EASTERN DISTRICT OF LOUISIANA
TOMAS REY, et al. CIVIL ACTION
VERSUS NO. 21-1188
LCMC HEALTHCARE PARTNERS, SECTION M (1)
LLC, et al.
ORDER & REASONS
Before the Court is a motion in limine filed by defendants LCMC Healthcare Partners,
LLC, Louisiana Children’s Medical Center, Children’s Hospital, and LCMC Health Holdings, Inc.
(collectively, “Defendants”), seeking to exclude Arno Bommer’s expert opinions and testimony
and to bar any other expert testimony and opinions offered on plaintiffs’ behalf.1 Plaintiffs Tomas
Rey, Melisa Rey, Robert Denny, Victoria Emmerling, and Nicole Williamson (collectively,
“Plaintiffs”) respond in opposition,2 and both sides reply in further support of their respective
positions.3 Also before the Court is Defendants’ motion for summary judgment,4 to which
Plaintiffs respond in opposition,5 and both sides reply in further support of their respective
positions.6 Having considered the parties’ memoranda, the record, and the applicable law, the
Court issues this Order & Reasons.
I. BACKGROUND
This matter concerns complaints of noise caused by the operation of a patient-transport
helicopter to and from a helistop at Children’s Hospital in uptown New Orleans. Children’s

Hospital is a non-profit pediatric medical center that, since 1955, has operated as the Gulf South’s
only freestanding, comprehensive hospital for children.7 The hospital maintains a helicopter,
known as “Abby,” that transports critically ill and injured children from across the state and region
to the facility to receive life-saving care that cannot be provided elsewhere.8 Prior to May 18,
2020, Abby was operated from a helipad atop a one-story surgery building on the river side of the
hospital complex and next to one of the hospital’s towers.9 In December 2018, John Nickens, the
president and CEO of Children’s Hospital, decided to relocate the helipad to the top of the newly-
built “Infill Tower.”10 The Infill Tower is six stories high and “in the middle of [the hospital’s]
campus.”11 The City of New Orleans, the Louisiana Department of Transportation, and the Federal
Aviation Administration (“FAA”) granted the required approvals.12 The FAA “certified the new
helipad’s location, coordinates, dimensions, obstruction clearance and approved flight paths to and
from the new helipad.”13 On May 18, 2020, Defendants opened the new helipad and the old one
atop the surgery center was decommissioned.14
Plaintiffs, five residents who live near Children’s Hospital, filed this action in state court
as a putative class action alleging that Abby’s new helipad and flight path afflict them with
unacceptable levels of noise and vibration.15 They allege that the helicopter’s flights directly over
their homes and its takeoffs and landings from the heliport adjacent to the neighborhood “at all
hours of the day and night … emit deafening sounds and vibrations significant enough to cause

physical and mental discomfort, property damage, and annoyance,” and thus constitute a
nuisance.16 Plaintiffs seek an injunction requiring Defendants to move the heliport back to its old
location or to another area that will not continue to damage and interfere with the enjoyment of
their property.17 Alternatively, they seek an injunction requiring Defendants to abate the helicopter
noise and vibrations.18 Plaintiffs also seek damages for personal injury and property damage under
Louisiana Civil Code articles 667, 668, and 669 (nuisance) and articles 2315 and 2317
(negligence).19 Specifically, Plaintiffs contend that they have sustained the following items of
damages: (1) hearing loss; (2) sleep disturbance; (3) mental health issues; (4) diminution of
property value; (5) property damage; (6) loss of use of their property; (7) cost to remediate their
property; (8) physical and mental suffering; (9) inconvenience; (10) past, present, and future
medical expenses; and (11) past, present, and future physical and mental pain and suffering.20
Defendants removed the action from state court to this Court asserting federal-question
subject-matter jurisdiction on the premise that Plaintiffs’ claim for injunctive relief, which seeks
to compel the relocation of the heliport, is preempted by federal law, specifically, the Federal
Aviation Act (“FAA”), 49 U.S.C. §§ 40101 et seq.21 In their notice of removal, Defendants also
invoked diversity subject-matter jurisdiction under the Class Action Fairness Act (“CAFA”), 28
U.S.C. § 1332(d).22
Plaintiffs moved to remand.23 The Court denied the motion, holding that CAFA provided
diversity jurisdiction over this action under 28 U.S.C. § 1332, and thus, it was unnecessary for the

Court to analyze whether it also had federal-question jurisdiction under 28 U.S.C. § 1331.24
Plaintiffs then asked the Fifth Circuit for leave to appeal, which the appellate court denied.25
Thereafter, Plaintiffs amended their complaint to remove the class-action allegations and
moved this Court to decline supplemental jurisdiction under 28 U.S.C. § 1332 since the basis for
jurisdiction under CAFA no longer existed.26 The Court denied the motion, holding that Plaintiffs’
dismissal of the class-action allegations plainly amounted to forum shopping and that jurisdiction
was appropriately exercised under § 1367.27
Defendants then moved for partial judgment on the pleadings, arguing that the Plaintiffs’
request for a permanent injunction was preempted by the FAA.28 The Court denied the motion
without prejudice, permitting Defendants to reassert the arguments in an appropriate motion
following discovery.29
Next, Defendants moved to dismiss all claims of this lawsuit pursuant to Rule 12(c) of the
Federal Rules of Civil Procedure, arguing that the noise and vibration resulting from helicopter
operations at their helistop do not constitute actionable nuisance because the noise level complies
with local ordinances.30 Plaintiffs countered with a motion to strike Defendants’ motion to dismiss
as untimely pursuant to Rule 12(g) of the Federal Rules of Civil Procedure.31 The Court denied
both motions, finding that Plaintiffs’ claims were not ripe for resolution on the face of the
pleadings.32

Now that discovery has been conducted, Defendants file the instant motion in limine and
motion for summary judgment.33 In the motion in limine, Defendants argue that Bommer,
Plaintiffs’ sound expert, should be precluded from testifying because his opinions and
methodology do not satisfy Daubert.34 Defendants also argue that Plaintiffs should be precluded
from offering expert opinions from any other witness because they failed to produce expert reports
or summaries in compliance with Rule 26 of the Federal Rules of Civil Procedure.35 Defendants
also move for summary judgment, contending that Plaintiffs’ claim for injunctive relief is
preempted by the FAA and they cannot prevail on the nuisance and negligence claims for
damages.36
II. LAW & ANALYSIS
A. Defendants’ Motion In Limine
1. Arno Bommer
Plaintiffs retained Arno Bommer, a consultant with Collaboration in Science and
Technology Inc., to serve as an acoustics expert.37 In 1982, Bommer received a bachelor’s of
science degree in architectural design from the Massachusetts Institute of Technology and has
worked as an acoustical consultant ever since.38 He is a member of the Acoustic Society of
America and is board certified by the Institute of Noise Control Engineering.39 Bommer has
“designed walls and ceilings to improve noise isolation and/or speech privacy” for various types

of buildings, including residences.40 He has contributed to numerous publications and has
previously testified as an expert witness.41
In this case, Bommer attempted to measure the impact of the noise from Defendants’
helicopter using what he refers to as “a common method” that compares “the level of the intruding
sounds with the ambient sound level.”42 He explains that “[a]n increase of 10 dBA [(A-weighted
decibels)] is typically perceived as being about twice as loud and is used by some regulatory
agencies to define a significant increase.”43 Bommer cites six ordinances or guidelines that were
not promulgated in Louisiana and do not relate to aviation that “define a noise impact as 10 dBA
above ambient.”44 Using this method, Bommer took sound readings at several locations at various
times in the summer of 2021 and purports to show that the noise level increased significantly when
Defendants’ helicopter was in operation.45 Bommer explains that numerous factors contribute to
the noise level at the various locations, such as the distance from the helipad and obstructions that
block the noise.46 Ultimately, Bommer opines that:
Noise from hospital helicopter operations is loud and pervasive throughout the
neighborhood north of the hospital within about 1300 ft of the helipad. The levels
of sound are much greater than ambient sound levels and exceed common
guidelines. They are sufficiently loud to cause annoyance and aggravation, to
interfere with the use of property outside residences, and to interfere with sleep
within residences. This can reduce property values and adversely affect learning
and health. It is my judgment that sound levels from [the helicopter] are more
probable than not to constitute a nuisance to people of normal sensitivities. To
prevent this, significant reduction of sound levels must be achieved either by
relocating the helipad and flight paths and/or by significantly modifying the
residences for improved sound isolation.47
40 Id. at 22.
41 Id. at 23-24. Defendants do not generally contest that Bommer is qualified to testify as an acoustics expert.

Bommer offers the following suggestions for noise control: use quieter helicopters, move the
helipad oriented away from the residences, refuel the helicopter at the helipad to reduce flights,
use different flight paths away from the neighborhood, and modify the residences for better sound
isolation with certain types of windows, walls, doors, vents, and roofs.48
Defendants seek to preclude Bommer from testifying at trial because, say Defendants, he
failed to use a proper methodology and ensure that his noise-impact opinions were supported by
the facts.49 Defendants first argue that Bommer failed to establish that the noise from the helicopter
is excessive in light of local ordinances, specifically, the New Orleans Comprehensive Zoning
Ordinance and New Orleans Noise Ordinance (the “city noise ordinance”)50 that does not use a 10
dBA standard and from which emergency vehicles are exempt, and FAA noise regulations that
employ the day-night average sound level (DNL) to measure sound, which is a different measure
than the one used by Bommer.51 Defendants further argue that the “common method” Bommer
used, isolating the single-event noise (supposedly Defendants’ helicopter) from ambient sound, “is
what the on-point FAA standard is designed to avoid.”52 Next, Defendants contend that Bommer
48 Id. at 17-19.
49 R. Doc. 105-1 at 1, 5-11.
50 The city noise ordinance provides that the sound level limit for a residential area is between 60 L10 dBA
and 70 Lmax dBA from 7:00 a.m. to 10:00 p.m., and between 55 L10 dBA and 60 Lmax dBA from 10:00 p.m. to 7:00
a.m. CODE OF THE CITY OF NEW ORLEANS § 66-202 (2025). “L10 means the A-weighted sound pressure level which
is exceeded ten percent of the time period during which the measurement is made.” Id. § 66-136. “Lmax means the A-
weighted sound level allowed.” Id. “Noises resulting from any authorized emergency vehicles when responding to
an emergency” are exempt from the sound level limits. Id. § 66-138(2). “Emergency vehicles” are defined as
“authorized publicly or privately owned ambulances, or motor vehicles belonging to a fire or police department, or to
any federal, state, parish or municipal agency provided such vehicles are in use as emergency vehicles by one
authorized to use such vehicles for that purpose.” Id. § 66-136. “Emergency means any occurrence or set of
circumstances involving actual or eminent [sic] physical trauma or property damage which demands immediate
attention.” Id. (emphasis in original).
51 R. Doc. 105-1 at 5-10. DNL “means the 24-hour average sound level, in decibels, for the period from
midnight to midnight, obtained after the addition of ten decibels to sound levels for the periods between midnight and
7 a.m., and between 10 p.m., and midnight, local time.” 14 C.F.R. § 150.7. Aircraft noise at a level below 65 DNL
is considered compatible with all land uses. See id. § A150.101 & Table 1. “The DNL is the standard form of noise
measurement employed by the FAA, the United States Department of Housing and Urban Development, the
Department of Defense, and other federal agencies.” Zbitnoff v. James, 2016 WL 4251047, at *5 (D. Vt. Aug. 10,
2016), aff’d, 708 F. App’x 25 (2d Cir. 2017).

failed to ensure that sound spikes were emanating from the Defendants’ helicopter, and Plaintiffs’
attorneys, not Bommer, chose residences at which sound was measured, meaning that Bommer
cannot say that his measurements were representative of every single residence in the
neighborhood.53 Finally, Defendants urge that Bommer cannot offer opinions in “areas on which
he is not an expert or failed to conduct any expert analysis, such as health and medical conditions,
property values, home remediation and aviation safety.”54 At his deposition, say Defendants,
Bommer admitted that: (1) he is not a real estate expert and has not determined whether Plaintiffs
experienced a reduction in their property values; (2) he is not a medical doctor or an expert on
whether the noise caused any specific medical condition in any Plaintiff; (3) he has not inspected
Plaintiffs’ residences to determine what noise-reduction modifications would be appropriate or the
cost of such work; and (4) he is not an aviation expert and cannot opine on the feasibility of moving
the helipad back to its old location, changing flight paths, or using the helipad only for specific
purposes.55
Plaintiffs respond in opposition, arguing that Bommer’s use of the “common method” to
quantify noise was appropriate because it captured the effects of the “short, high-intensity
helicopter noise events,” which the DNL does not accurately measure in terms of noise impact.56
Plaintiffs explain how Bommer conducted his test and advocate that the test was appropriate to
measure “ambient conditions without helicopters and during helicopter takeoffs and landings” at
different locations to determine the effect the sudden noise has on the residents.57 Plaintiffs also

corporate representative, Evan Bertucci, and Defendants’ sound expert, Eugene M. Reindel. Id. at 3-7. Because the
testimony of Bertucci and Reindel is not relevant to determining whether Bommer may testify as an expert, the Court

contend that the FAA regulations do not apply to the private heliport at issue.58 Plaintiffs say that
the “question of the reliability of the application of the methodologies is dependent upon the
credibility of the results, which is a weight issue.”59 Further, Plaintiffs argue that Bommer is
qualified to testify as to ways to remediate the noise, which, in his opinion, ultimately involves
moving the helipad back to its old location.60 Finally, Plaintiffs urge that Bommer did not need to
consider the New Orleans noise ordinance because injunctive relief is available when excessive
noise amounts to an abuse of property rights.61
In reply, Defendants contend that Plaintiffs failed to “establish by a preponderance of the
evidence that Mr. Bommer’s methodology and opinions are reliable and supported by the facts.”62
Defendants again emphasize that Louisiana law requires the suppression of noise only if it is
excessive under local ordinances or customs, and Bommer failed to consider those ordinances in
rendering his opinions, particularly that the New Orleans Department of Health “has rejected
application of the [city noise] ordinance to [Defendants’] helicopter operations.”63 Defendants
continue to assert that the DNL standard employed by the FAA is the correct measure of aviation
noise and that Bommer cited “five obscure state or regulat[ory] provisions governing noise other
than aviation no[i]se” and failed to explain how they apply here.64 Moreover, say Defendants,
Plaintiffs failed to show that Bommer’s opinions are reliable and supported by the facts because
he testified that he did not verify whether the noise spikes he measured came from Defendants’

helicopter.65 Further, Defendants urge that, under Rule 702, “the sufficiency of an expert’s basis
and the application of the expert’s methodology” go to the admissibility of the testimony, not just
its weight.66 Defendants also maintain that Plaintiffs did not “establish that Mr. Bommer can offer
opinions on areas on which he is not an expert or failed to conduct any expert analysis,” such as
property values, health effects, sleep disturbances, residential sound modifications, or aviation
related topics.67
In their surreply, Plaintiffs reurge that Bommer’s method and the DNL are both appropriate
measures of noise, but that Bommer’s way is superior for the issue at hand.68 Plaintiffs also state
that Bommer did not need to calculate whether the helicopter violated the city noise ordinance.69
In a sur-surreply, Defendants again argue that Bommer’s methodology is unreliable
because he did not establish that the helicopter noise is excessive under the city noise ordinance, a
custom, or standard practice.70 Defendants assert that Bommer’s “common method” is not
“custom and standard practice,” but instead relies on “five obscure regulations dealing with
construction, wind farms, and other non-aviation noise to justify its use.”71 And again, Defendants
contend that the DNL is the customary method for measuring aviation noise.72 Finally, Defendants
note that “Plaintiffs do not address in their sur-reply why Mr. Bommer’s expert opinion on matters
on which he is not an expert or did not conduct any expert analysis should be excluded.”73
A district court has discretion to admit or exclude expert testimony under the Federal Rules

Pharmaceuticals, Inc., 509 U.S. 579, 589 (1993), the Supreme Court held that Rule 702 of the
Federal Rules of Evidence requires a district court to act as a gatekeeper to ensure that “any and
all scientific testimony or evidence admitted is not only relevant, but reliable.” Rule 702 provides:
A witness who is qualified as an expert by knowledge, skill, experience, training,
or education may testify in the form of an opinion or otherwise if the proponent
demonstrates to the court that it is more likely than not that:
(a) the expert’s scientific, technical, or other specialized knowledge will help the
trier of fact to understand the evidence or to determine a fact in issue;
(b) the testimony is based on sufficient facts or data;
(c) the testimony is the product of reliable principles and methods; and
(d) the expert’s opinion reflects a reliable application of the principles and methods
to the facts of the case.
The reliability inquiry requires a court to assess whether the reasoning or methodology
underlying the expert’s testimony is valid. See Daubert, 509 U.S. at 592-93. In Daubert, the
Supreme Court listed several non-exclusive factors for a court to consider in assessing reliability:
(1) whether the theory has been tested; (2) whether the theory has been subjected to peer review
and publication; (3) the known or potential rate of error; and (4) the general acceptance of the
methodology in the scientific community. Id. at 593-95. However, a court’s evaluation of the
reliability of expert testimony is flexible because “[t]he factors identified in Daubert may or may
not be pertinent in assessing reliability, depending on the nature of the issue, the expert’s particular
expertise, and the subject of his testimony.” Kumho Tire Co. v. Carmichael, 526 U.S. 137, 150
(1999) (quotations omitted). In sum, the district court must ensure “that an expert, whether basing
testimony upon professional studies or personal experiences, employs in the courtroom the same
level of intellectual rigor that characterizes the practice of an expert in the relevant field.” Id. at
152. The party offering the testimony must establish its reliability by a preponderance of the
evidence. See Moore v. Ashland Chem. Inc., 151 F.3d 269, 276 (5th Cir. 1998).
Next, the district court must determine whether the expert’s reasoning or methodology
“fits” the facts of the case and whether it will assist the trier of fact to understand the evidence,
i.e., whether it is relevant. Daubert, 509 U.S. at 591. An expert’s testimony is not relevant and
may be excluded if it is directed to an issue that is “well within the common sense understanding
of jurors and requires no expert testimony.” Vogler v. Blackmore, 352 F.3d 150, 155 (5th Cir.
2003). Further, an expert cannot make “legal conclusions reserved for the court,” credit or
discredit witness testimony, or “otherwise make[] factual determinations reserved for the trier of
fact.” Highland Cap. Mgmt., L.P. v. Bank of Am., N.A., 574 F. App’x 486, 491 (5th Cir. 2014).
Rule 702 also requires that an expert be properly qualified. Generally, if there is some
reasonable indication of qualifications, the district court may admit the expert’s testimony, and
then the expert’s qualifications become an issue for the trier of fact. Rushing v. Kan. City S. Ry.
Co., 185 F.3d 496, 507 (5th Cir. 1999), superseded in part by statute on other grounds as noted in
Lester v. Wells Fargo Bank, N.A., 805 F. App’x 288, 291 (5th Cir. 2020). A witness qualified as
an expert is not strictly confined to his area of practice but may testify regarding related
applications; a lack of specialization goes to the weight, not the admissibility of the opinion. Cedar
Lodge Plantation, L.L.C. v. CSHV Fairway View I, L.L.C., 753 F. App’x 191, 195-96 (5th Cir.
2018).
The facts, data, and sources used in an expert’s opinion are generally considered by the
jury in weighing the evidence, but “in some cases ‘the source upon which an expert’s opinion
relies is of such little weight that the jury should not be permitted to receive that opinion.’” Jacked
Up, L.L.C. v. Sara Lee Corp., 807 F. App’x 344, 348 (5th Cir. 2020) (quoting Viterbo v. Dow
Chem. Co., 826 F.2d 420, 422 (5th Cir. 1987)). As the gatekeeper, a district judge must “extract
evidence tainted by farce or fiction. Expert evidence based on a fictitious set of facts is just as
unreliable as evidence based upon no research at all.” Guillory v. Domtar Indus. Inc., 95 F.3d
1320, 1331 (5th Cir. 1996). “Generally, the fact-finder is entitled to hear an expert’s testimony
and decide whether the predicate facts on which the expert relied are accurate. At the same time,
however, expert testimony that relies on completely unsubstantiated factual assertions is
inadmissible.” Moore v. Int’l Paint, L.L.C., 547 F. App’x 513, 515 (5th Cir. 2013) (internal
quotation marks, alterations, and citations omitted). Ultimately, the expert must “‘bring to the jury
more than the lawyers can offer in argument.’” Salas v. Carpenter, 980 F.2d 299, 305 (5th Cir.
1992) (quoting In re Air Crash Disaster at New Orleans, 795 F.2d 1230, 1233 (5th Cir. 1986)).
Here, Bommer is qualified to testify as an expert in acoustics. While his methodology
differs from that employed by Defendants’ expert and the FAA, the Court cannot say that it was
an improper means to measure the effects of the helicopter noise on the surrounding neighborhood.
That the FAA standard (DNL) has been applied by other courts, see Seattle Cmty. Council Fed’n
v. FAA, 961 F.2d 829, 833 (9th Cir. 1992); Hausrath v. U.S. Dep’t of the Air Force, 491 F. Supp.
3d 770, 788 (D. Idaho 2020); Friends of the E. Hampton Airport, Inc. v. Town of E. Hampton, 152
F. Supp. 3d 90, 110-11 (E.D.N.Y. 2015), and “‘courts have consistently upheld the [FAA’s]
discretion to choose its cumulative noise impact methodology [DNL] instead of single-event noise
analysis’” when the agency evaluates the noise impact of aircraft, Citizens of the Ebey’s Rsrv. for
a Healthy, Safe & Peaceful Env’t v. U.S. Dep’t of the Navy, 122 F. Supp. 3d 1068, 1079-80 (W.D.
Wash. 2015) (quoting City of Bridgeton v. FAA, 212 F.3d 448, 460 (8th Cir. 2000)), does not mean
that the DNL is the only way to measure the impact of aviation noise for purposes of a state-law
nuisance claim. Defendants do not cite, and the Court is not aware of, any cases applying the
FAA’s DNL to such claims. Moreover, Bommer’s failure to calculate whether the noise complied
with the city noise ordinance is not fatal to the admissibility of his testimony. As discussed later
in this opinion, the city noise ordinance is but one factor that is considered in determining whether
the helicopter is a nuisance under state law, so Defendants’ compliance or noncompliance with it
is not determinative. Defendants can address the differences between Bommer’s methodology,
and the methodology and measure used by their expert, the FAA, and the city noise ordinance,
through vigorous cross-examination and the presentation of countervailing expert testimony.
More concerning is Bommer’s failure to verify that the sound spikes he measured emanated
from Defendants’ helicopter. Bommer admitted in his deposition that he did not use the flight logs
provided by Defendants to verify whether the supposed helicopter noise recorded during his study
was actually produced by a helicopter at all, much less Defendants’ helicopter.74 This lapse may
reduce the reliability of Bommer’s testimony, but it does not undermine it completely. Again,
Defendants can employ vigorous cross-examination and countervailing expert testimony to expose
this hole in Bommer’s opinions.
Lastly, the Court does hold that Bommer cannot offer opinions on topics for which he is
not an expert or failed to conduct any expert analysis. In his deposition, Bommer admitted that he
did not conduct any analysis concerning what noise-remediation modifications could be made on
the Plaintiffs’ homes and he is not giving an opinion on that topic.75 He also admitted that he is
not a real estate expert and has not analyzed whether the Plaintiffs’ property values decreased as a
result of Defendants’ relocation of the helipad.76 Further, Bommer testified that he is not a medical
doctor or expert on whether the helicopter noise caused any specific medical condition in any

plaintiff.77 And, finally, Bommer has no expertise in aviation.78 Accordingly, because Bommer
lacks expertise or did not perform any expert analysis in these areas, he cannot offer any expert
testimony in the areas of property valuation as a function of the helicopter noise, health effects of
the helicopter noise, sleep disturbances caused by the helicopter noise, residential sound
modifications to abate the helicopter noise, or aviation-related topics, such as the feasibility of
moving the helipad back to its old location, changing flight paths, or using the helipad only for
specific purposes.
2. Other Experts
Defendants move to exclude any expert opinions and testimony from individuals not
properly disclosed by Plaintiffs pursuant to Rule 26.79 Defendants indicate that, save for Bommer,
Plaintiffs did not disclose or produce under Rule 26(a)(2)(B) reports for any retained experts, nor
did Plaintiffs provide proper disclosures for any non-retained experts pursuant to Rule
26(a)(2)(C).80 However, say Defendants, Plaintiffs’ witness list “discloses several individuals
whose description of testimony could be expert opinions although the cryptic summaries make
that unclear.”81 Specifically, the witness list says that: Dr. Mario Sicassa, Helen Cappo, Malies
Harold Counseling, and Debbie Granier will testify for plaintiff Melisa Rey about “[m]ental health
issues associated with helicopter noise”; Dr. Michael Darrin will testify about a “[s]leep study to
help Melisa Rey find ways to manage her sleep”; architect Gregory J. Hackenberg will testify
about “[a]coustic recommendations”; and Brien Rau of Rau Builds, LLC will testify about
“[e]stimates for acoustic recommendation work” and “the remediation work performed on the

[Reys’] house, including sound proofing.”82 Defendants argue that, to the extent any of the
healthcare providers or therapists are being called to offer medical causation opinions, their
testimony should be excluded because Plaintiffs did not provide the disclosures required by Rule
26(a)(2)(C).83 Similarly, Defendants contend that, “to the extent [Hackenberg and Rau] are being
called to offer acoustic analysis and recommendations and whether they could be applied to
Plaintiffs’ residence[s] or other residences,” those witnesses should be excluded because Plaintiffs
did not provide Rule 26(a)(2)(B) reports or Rule 26(a)(2)(C) disclosures.84 Finally, Defendants
assert that Plaintiffs cannot elicit expert opinions from Bill Davis, the president of Heliport
Systems, Inc. (“Heliport Systems”), because Plaintiffs did not produce a Rule 26(a)(2)(B) expert
report for Davis or disclose him as a non-retained expert under Rule 26(a)(2)(C).85 Defendants
are concerned that Plaintiffs seek to use Davis as an expert because Plaintiffs state in their witness
list that Davis will testify about topics that Defendants say “clearly require expert opinions,” such
as “moving the helistop to its original location and reducing flights,” as well as “the FAA’s
involvement with the noise associated with landings and take offs.”86 Defendants represent that
their concern stems from Plaintiffs’ prior request for an extension of time to obtain an expert report
from Davis, which idea Plaintiffs abandoned in favor of Davis being a fact witness when
Defendants objected to the requested extension.87 Defendants further explain that Davis testified
as Heliport Systems’ corporate representative in a deposition taken pursuant to Rule 30(b)(6) of

the Federal Rules of Civil Procedure, and as such, say Defendants, any attempt by Plaintiffs to use
that deposition as the basis for expert testimony would be improper.88
Plaintiffs oppose the motion, arguing that Melisa Rey “disclosed all medical providers who
treated her for sleep disturbances and stress and anxiety from the helicopter noise in her initial
response to discovery in April of 2022 and in a second set of discovery sent by [Defendants].”89
Plaintiffs state that Defendants obtained Dr. Rebekah A. Byrne’s90 and Harold’s records for their
treatment of Melisa Rey, which contain their respective opinions that Defendants’ helicopter is a
cause of her anxiety and sleep issues.91 Plaintiffs also say that “Melissa [sic] Rey provided a
detailed explanation of her medical treatment in her responses to discovery and deposition” and
that “[h]er medical records note her history, diagnosis and treatment.”92 As to Hackenberg and
Rau, Plaintiffs contend that they met their discovery obligations by sending Defendants’ counsel
“all of the architecture plans, estimate and work performed, including the acoustical work.”93
Further, with respect to Davis, Plaintiffs assert that they “notified [Defendants’ counsel] by email
that Bill Davis would be called as an expert witness, attaching his Rule 26 testimony list and
curriculum vitae” and that “Davis further disclosed all of his opinions in his deposition.”94
In reply, Defendants reurge that Plaintiffs did not properly disclose Melisa Rey’s healthcare
providers and therapists or Hackenberg and Rau as retained or non-retained experts, and as such,
none of them can offer expert testimony.95 Defendants explain that production of the medical
records and construction contract documents in discovery is insufficient to satisfy the mandates of

Rules 26(a)(2)(B) or (C).96 As to Davis, Defendants reassert that Plaintiffs’ counsel asked for an
extension of the expert report deadline on the due date to obtain a report from Davis, but abandoned
the idea when Defendants’ counsel objected to the extension.97 Defendants also reiterate that
Davis was deposed as Heliport Systems’ corporate representative under Rule 30(b)(6), not as an
individual.98 In sum, Defendants contend that Davis can offer no expert opinions because
Plaintiffs did not properly disclose him as a retained or non-retained expert.99
Plaintiffs again claim in their surreply that production of Melisa Rey’s medical records and
“the completed remediation specifications for the renovation” are sufficient to prevent prejudice
to Defendants.100 Plaintiffs also argue that they should be able to use Davis as an expert witness,
even without a report, because Defendants were going to use him as an expert and relied on him
“for every facet of its original and new helistop.”101 Plaintiffs further assert that they referred to
Davis’s deposition because he “could not be forced to provide a report” and his opinions were
previously disclosed to Defendants.102
In their sur-surreply, Defendants reassert that Davis was not properly disclosed as an expert
under either Rule 26(a)(2)(B) or (C), and that Plaintiffs’ reference to Helistop Systems’ corporate
deposition does not suffice to make Davis an expert.103 Defendants also say that their own
consulting relationship with Davis does not “render him an expert” witness.104 Further, Defendants
reurge that production of Melisa Rey’s medical records is insufficient under Rule 26 to put them
“on notice that the medical providers would be experts” because they “should not have to guess as

to who Plaintiffs may call as non-retained experts or what opinions they may or may not offer
many of which, such as causation, may not be stated in the medical records.”105 Defendants state
that the same logic applies to Hackenberg and Rau.106 In sum, Defendants contend that they
“should not be required to depose multiple medical providers and contractors to determine what
their opinions are and guess whether they will provide expert rather than fact testimony at trial,”
because “Rule 26 and this Court’s Scheduling Order require more.”107
Rule 26(a)(2) of the Federal Rules of Civil Procedure governs the disclosure of expert
testimony. The rule provides a distinction between the type of report required of a retained expert
– someone with no prior knowledge of the case who is enlisted to provide expert testimony – and
a non-retained expert – a witness whose testimony arises from his or her “ground-level
involvement in the events giving rise to the litigation.” AX Wireless LLC v. Dell Inc., 2024 WL
1495784, at *1 (E.D. Tex. Apr. 5, 2024) (quotation omitted). The party sponsoring the testimony
must demonstrate whether its experts are retained or not. Id.
A retained expert is required to prepare and sign an expert report pursuant to Rule
26(a)(2)(B). The report must contain: “a complete statement of all opinions the witness will
express and the basis and reasons for them”; “the facts or data considered by the witness in
formatting them”; “any exhibits that will be used to summarize or support them”; “the witness’s
qualifications, including a list of all publications authored in the previous 10 years”; “a list of all
other cases in which, during the previous 4 years, the witness testified as an expert at trial or by
deposition”; and “a statement of the compensation to be paid for the study and testimony in the
case.” Fed. R. Civ. P. 26(a)(2)(B)(i)-(vi).

107 Id.
Prior to 2010, non-retained experts were exempt from Rule 26’s expert reporting
requirements. See Tucker v. United States, 2019 WL 4198254, at *2 (E.D. La. Sept. 4, 2019). In
2010, Rule 26(a)(2)(C) was added, which provides a modified disclosure requirement applicable
to non-retained experts, such as treating physicians. Id. Rule 26(a)(2)(C) requires that a party,
with respect to a non-retained expert, provide a written disclosure, in lieu of a report, stating: “(i)
the subject matter on which the witness is expected to present evidence under Federal Rule of
Evidence 702, 703, or 705; and (ii) a summary of the facts and opinions to which the witness is
expected to testify.”
A Rule 26(a)(2)(C) disclosure “need not be extensive,” but must include “an abstract,
abridgement, or compendium of the opinion and facts supporting the opinion.” Causey v. State
Farm Mut. Auto. Ins. Co., 2018 WL 2234749, at *2 (E.D. La. May 16, 2018) (quotation omitted;
emphasis in original); see AX Wireless, 2024 WL 1495784, at *1 (stating that “when a party fails
to provide a meaningful summary of the facts and opinions forming the basis of a non-retained
expert’s testimony, the disclosure is insufficient” (quotation, internal quotation marks, and
alteration omitted)). Although “the rule does not require overly comprehensive disclosure … it
does require disclosure in at least some form” in order “to provide opposing parties the opportunity
to prepare for effective cross-examination and to arrange for testimony from other experts, if
necessary.” Causey, 2018 WL 2234749, at *2 (emphasis in original); see also Collett v.
Weyerhaeuser Co., 512 F. Supp. 3d 665, 672 (E.D. La. 2021) (“In lieu of a report, the treating
physician’s records, summaries of the treatment, or a letter or summary report is produced
containing information sufficient to allow opposing counsel to understand the scope of the
expected testimony and supplement the information with a pretrial deposition.”), aff’d, 2022 WL
2387352 (5th Cir. July 1, 2022).
Rule 37(c)(1) states that, “[i]f a party fails to provide information or identify a witness as
required by Rule 26(a) …, the party is not allowed to use that information or witness to supply
evidence on a motion, at a hearing, or at a trial, unless the failure was substantially justified or is
harmless.” Further, this Court’s scheduling order states that “[t]he Court will not permit any
witness, expert or fact, to testify or any exhibits to be used unless there has been compliance with
this Order as it pertains to the witness and/or exhibits, without an order to do so issued on motion
for good cause shown.”108 The Fifth Circuit has outlined a four-factor standard to determine
whether the failure to meet Rule 26 disclosure requirements was substantially justified or is
harmless. Williams v. Louisiana, 2015 WL 5438596, at *5 (M.D. La. Sept. 11, 2015) (citing Sierra
Club, Lone Star Chapter v. Cedar Point Oil Co., 73 F.3d 546, 572 (5th Cir. 1996)). “To avoid
abusing their discretion, courts must: (1) examine the importance of the witness’s testimony; (2)
consider the prejudice, if any, to the opposing party of allowing the witness to testify; (3) decide
whether there is a possibility of curing such prejudice by granting a continuance; and (4) consider
the explanation, if any, for the party’s failure to comply with the discovery requirements.” Id.
(citing Sierra Club, 73 F.3d at 572).
Plaintiffs utterly failed to comply with Rules 26(a)(2)(B) and (C) with respect to disclosing
Davis, Hackenberg, Rau, and Melisa Rey’s healthcare providers and therapists, whether as retained
or non-retained experts. With respect to Davis, Plaintiffs do not deny that they did not obtain an
expert report from Davis, but rather baldly state that sending Davis’s curriculum vitae and “Rule
26 testimony list” to defense counsel constitutes a sufficient disclosure because Davis was
deposed.109 The lack of a Rule 26(a)(2)(B) expert report is fatal to Plaintiffs’ misguided attempt
to use Davis as a retained expert. Moreover, Davis cannot testify as a non-retained expert because
108 R. Doc. 93 at 3.
109 R. Docs. 120 at 13; 138 at 4-5.
Plaintiffs provided no meaningful summary of the facts and opinions forming the basis of Davis’s
testimony as would satisfy Rule 26(a)(2)(C), “[a]nd referral to depositions is not an adequate
substitute for the summary required by Rule 26.” AX Wireless, 2024 WL 1495784, at *1 (quotation
omitted). Plaintiffs offer no explanation for their failure and the Court sees no good cause to
excuse them from complying with Rule 26. Thus, although Davis may testify as a fact witness,
Plaintiffs may not attempt to elicit expert opinions from him.
Plaintiffs also failed to provide Rule 26(a)(2)(C) summaries of the expected testimony from
Melisa Rey’s healthcare providers and therapists. Instead, Plaintiffs insist that providing the
records from these witnesses is sufficient “to provide notice of the nature and extent of the
testimony that is going to be offered.”110 It is not. “Providing medical records and expecting
defendants to search for the opinions that may be contained therein does not satisfy Rule
26(a)(2)(C).” Matthews v. Amtrust Grp., Ins., 2020 WL 206186, at *2 (E.D. La. Jan. 14, 2020).
To allow such a practice places the onus on Defendants to search the medical records for any
causation opinions and the supporting facts, which opinions, say Defendants, are not present in the
medical records.111 Again, Plaintiffs offer no explanation for their failure and the Court sees no
good cause to excuse them from complying with Rule 26. Accordingly, none of Melisa Rey’s
healthcare providers or therapists can offer causation opinions as an expert, although they can
testify about any causation determination necessary to and made during the course of Melisa Rey’s
treatment, if contained in the medical records.112 See Rea v. Wis. Coach Lines, Inc., 2014 WL
4981803, at *5-6 (E.D. La. Oct. 3, 2014) (excluding treating physician’s causation opinions that

that “[t]he Court will not permit any witness, expert or fact, to testify or any exhibits to be used unless there has been
compliance with this Order as it pertains to the witness and/or exhibits, without an order to do so issued on motion for
good cause shown”).
were not established by the medical records when plaintiff failed to comply with the disclosure
requirements of Rule 26(a)(2)(C)).
Lastly, it is unclear from the cryptic entries on the witness list whether Hackenberg and the
contractor Rau are being offered by Plaintiffs as retained or non-retained experts. Regardless, they
cannot testify as either type of expert because Plaintiffs failed to provide a Rule 26(a)(2)(B) report
or a Rule 26(a)(2)(C) disclosure with respect to these witnesses. And, again, Plaintiffs offer no
explanation for such failure and the Court sees no good cause to excuse them from complying with
Rule 26. As with the other improperly disclosed purported experts, the architect and contractor
can testify as fact witnesses, if appropriate, but Plaintiffs cannot elicit any expert opinions from
them.113
B. Defendants’ Motion for Summary Judgment
1. Summary Judgment Standard
Summary judgment is proper if the pleadings, depositions, answers to interrogatories, and
admissions on file, together with the affidavits, if any, show that there is no genuine issue as to
any material fact and that the moving party is entitled to a judgment as a matter of law. Celotex
Corp. v. Catrett, 477 U.S. 317, 322 (1986); Fed. R. Civ. P. 56. “Rule 56(c) mandates the entry of
summary judgment, after adequate time for discovery and upon motion, against a party who fails
to make a showing sufficient to establish the existence of an element essential to that party’s case,
and on which that party will bear the burden of proof at trial.” Celotex, 477 U.S. at 322. A party
moving for summary judgment bears the initial burden of demonstrating the basis for summary
judgment and identifying those portions of the record, discovery, and any affidavits supporting the
conclusion that there is no genuine issue of material fact. Id. at 323. If the moving party meets
113 The Court will not attempt to rule in a vacuum as to what these witnesses can or cannot say, but instead
will rule on contemporaneous objections lodged at trial.
that burden, then the nonmoving party must use evidence cognizable under Rule 56 to demonstrate
the existence of a genuine issue of material fact. Id. at 324.
A genuine issue of material fact exists if a reasonable jury could return a verdict for the
nonmoving party. See Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 248 (1986). The substantive
law identifies which facts are material. Id. Material facts are not genuinely disputed when a
rational trier of fact could not find for the nonmoving party upon a review of the record taken as a
whole. See Matsushita Elec. Indus. Co. v. Zenith Radio Corp., 475 U.S. 574, 587 (1986); EEOC
v. Simbaki, Ltd., 767 F.3d 475, 481 (5th Cir. 2014). Unsubstantiated assertions, conclusory
allegations, and merely colorable factual bases are insufficient to defeat a motion for summary
judgment. See Anderson, 477 U.S. at 249-50; Little v. Liquid Air Corp., 37 F.3d 1069, 1075 (5th
Cir. 1994); Hopper v. Frank, 16 F.3d 92, 97 (5th Cir. 1994). In ruling on a summary-judgment
motion, a court may not resolve credibility issues or weigh evidence. See Delta & Pine Land Co.
v. Nationwide Agribusiness Ins. Co., 530 F.3d 395, 398-99 (5th Cir. 2008). Furthermore, a court
must assess the evidence, review the facts, and draw any appropriate inferences based on the
evidence in the light most favorable to the party opposing summary judgment. See Tolan v. Cotton,
572 U.S. 650, 656-57 (2014); Daniels v. City of Arlington, 246 F.3d 500, 502 (5th Cir. 2001). Yet,
a court only draws reasonable inferences in favor of the nonmovant “when there is an actual
controversy, that is, when both parties have submitted evidence of contradictory facts.” Little, 37
F.3d at 1075 (citing Lujan v. Nat’l Wildlife Fed’n, 497 U.S. 871, 888 (1990)).
After the movant demonstrates the absence of a genuine issue of material fact, the
nonmovant must articulate specific facts showing a genuine issue and point to supporting,
competent evidence that may be presented in a form admissible at trial. See Lynch Props., Inc. v.
Potomac Ins. Co., 140 F.3d 622, 625 (5th Cir. 1998); Fed. R. Civ. P. 56(c)(1)(A), (c)(2). Such
facts must create more than “some metaphysical doubt as to the material facts.” Matsushita, 475
U.S. at 586. When the nonmovant will bear the burden of proof at trial on the dispositive issue,
the moving party may simply point to insufficient admissible evidence to establish an essential
element of the nonmovant’s claim in order to satisfy its summary-judgment burden. See Celotex,
477 U.S. at 322-25; Fed. R. Civ. P. 56(c)(1)(B). Unless there is a genuine issue for trial that could
support a judgment in favor of the nonmovant, summary judgment must be granted. See Little, 37
F.3d at 1075-76.
2. FAA preemption
Defendants move for summary judgment on Plaintiffs’ request for a preliminary injunction
requiring them to relocate the helipad and change the flight paths to abate the noise, arguing that
such a remedy is preempted by the FAA, because both moving the helipad and changing flight
paths affect federally controlled airspace.114 Defendants point to the testimony of Bertucci and
Heliport Systems and the report of Keith Cianfrani, their aviation expert, to support their
argument.115 Bertucci, say Defendants, testified that “the FAA determined the primary and
secondary routes to and from the helipad based on historical wind patterns, obstructions, and
helipad orientation.”116 And Helipad Systems, which “designed, constructed and installed the new
helipad at [Children’s Hospital] testified about the FAA approval process for the relocated
helipad,” involving the FAA’s “evaluat[ion] whether the proposed flight paths conflict with flight
paths from other airports or helipads and … confirm[ation] that there are no obstructions that the
helicopter can hit using those flight paths.”117 Then the FAA issues a letter of determination.118

115 Id. at 13-14.
116 Id. at 13.
117 Id.
118 Id.
Defendants observe that aviation expert Cianfrani, in his report, explains that, before the helipad
could be moved back to its old location, the FAA would have to conduct a new airspace study, and
approval is not guaranteed, because the old helipad has been decommissioned for five years during
which time circumstances could have changed.119
In their opposition, Plaintiffs argue that their request for an injunction arises from their
state-law nuisance claim, which they say is not preempted by the FAA.120 Plaintiffs contend that
their request for injunctive relief is not preempted because they “do not seek to control flight paths,
altitudes, or airspace management,” but “[r]ather, they challenge a discretionary land-use decision:
[Defendants’] choice to relocate [their] helipad from a buffered site to the rooftop of a tower
adjacent to homes,” which, say Plaintiffs, make “[t]he resulting noise and nuisance … questions
of state property law, not federal preemption.”121 While Plaintiffs acknowledge that FAA
regulations preempt state laws affecting airspace, they assert that the case law recognizes that state
and local authorities have control over land use for airports and heliports and allows for state-law
nuisance claims related to noise.122 Plaintiffs cite testimony from Bertucci, Heliport Systems, and
Cianfrani, which they claim supports their theory that the FAA does not regulate helipad noise or
site selection.123 Plaintiffs further admit that they “are not seeking to eliminate helicopter
operations or impede patient care,” but instead, “[t]hey seek only to require that the helipad be
located in a place that balances hospital needs with community welfare” in accord with local land-
use regulations and state nuisance law.124
119 Id. at 13-14. Defendants also argue that Plaintiffs cannot meet their burden to secure a mandatory
permanent injunction. Id. at 14-15. The Court need not discuss this because the Court finds that Plaintiffs’ request
for an injunction is preempted by the FAA.

124 Id. at 16.
In reply, Defendants reurge that Plaintiffs’ request for a mandatory injunction is
preempted.125 Defendants explain that their “motion does not argue that the FAA regulations
preempt state law nuisance and negligence claims or local land use regulation, such as zoning and
permitting.”126 But “[r]ather, [Defendants] argue[] only that FAA regulations preempt Plaintiffs’
request for a mandatory injunction that [Defendants] be ordered to ‘relocate [their] heliport’ and
otherwise abate noise from helicopters by relocating the helipad, which would necessarily
implicate FAA airspace and require FAA approval.”127 Defendants also point out that Plaintiffs’
injunction request is preempted by the FAA because: “(1) Plaintiffs testified that the flight paths
were an issue; and (2) the relocation of the helipad necessarily involves the FAA approving flight
paths to and from the helipad.”128 Again, Defendants contend that moving the helipad would
“require the FAA to conduct an aeronautical study to determine if the flight paths to the old pad
conflict with existing flight paths or obstructions in the area, some of which could have been put
in place during the previous five years.”129
Plaintiffs file a surreply reasserting that they only challenge Defendants’ land-use decision
on relocating the helipad and do not seek to control flight paths, altitudes, or airspace.130 Plaintiffs
acknowledge, however, that an injunction requiring a change in flight paths to abate noise is one
component of their claim.131 Additionally, Plaintiffs admit that “the FAA may be involved in
reviewing flight paths” for a helipad but, say Plaintiffs, that involvement does not warrant
preemption of their request for an injunction because “the process is straightforward” for
Defendants to “simply resubmit its proposed flight paths, and the FAA would either object or not

object.”132 Plaintiffs further maintain that the siting of helipads is a matter of local concern that is
not preempted by the FAA.133
In their sur-surreply, Defendants argue that, although “Plaintiffs admit that the FAA would
be involved in reviewing flight paths to and from the relocated helipad,” they downplay this
involvement without disputing “that the relocated helipad would not be allowed to operate unless
and until the flight paths were not objected to (approved) by the FAA.”134 Defendants again cite
evidence – namely, Heliport Systems’ testimony – of the necessity of the FAA’s involvement in
approving the location of the helipad.135
The analysis must begin with a discussion of preemption. The Supreme Court has
explained:
The Supremacy Clause provides that “the Laws of the United States” (as well
as treaties and the Constitution itself) “shall be the supreme Law of the Land ... any
Thing in the Constitution or Laws of any state to the Contrary notwithstanding.”
Congress may consequently pre-empt, i.e., invalidate, a state law through federal
legislation. It may do so through express language in a statute. But even where …
a statute does not refer expressly to pre-emption, Congress may implicitly pre-empt
a state law, rule, or other state action.
It may do so either through “field” pre-emption or “conflict” pre-emption. As
to the former, Congress may have intended “to foreclose any state regulation in the
area,” irrespective of whether state law is consistent or inconsistent with “federal
standards.” In such situations, Congress has forbidden the State to take action in
the field that the federal statute pre-empts.
By contrast, conflict pre-emption exists where “compliance with both state and
federal law is impossible,” or where “the state law ‘stands as an obstacle to the
accomplishment and execution of the full purposes and objectives of Congress.’”
In either situation, federal law must prevail.

Oneok, Inc. v. Learjet, Inc., 575 U.S. 373, 376-77 (2015) (internal citations omitted; emphasis in
original). Defendants here advocate for the application of “field preemption.”
Field preemption of “areas that have been traditionally occupied by the States” occurs only
where “congressional intent to supersede state laws [is] clear and manifest.” English v. Gen. Elec.
Co., 496 U.S. 72, 79 (1990) (quotations omitted); see also City of Burbank v. Lockheed Air
Terminal Inc., 411 U.S. 624, 643 (1973) (Rehnquist, J., dissenting) (recognizing that “noise
regulation has traditionally been an area of local, not national, concern”). Courts do not “infer pre-
emption from the comprehensiveness of regulations” because “agencies normally address
problems in a detailed manner and … we can expect that they will make their intentions clear if
they intend for their regulations to be exclusive.” Hillsborough Cnty. v. Automated Med. Lab’ys,
Inc., 471 U.S. 707, 717-18 (1985). Absent clear field preemption, state and local authorities may
identify additional needs or impose further requirements in a federally regulated field. Id. at 717.
However, once a court determines that field preemption applies, it must then determine whether
the state law at issue falls within the scope of the preemption. Goodspeed Airport LLC v. E.
Haddam Inland Wetlands & Watercourses Comm’n, 634 F.3d 206, 211 (2d Cir. 2011). “The key
question is thus at what point the state [law] sufficiently interferes with federal regulation that it
should be deemed pre-empted.” Gade v. Nat’l Solid Wastes Mgmt. Ass’n, 505 U.S. 88, 107 (1992).
As noted in Lewis v. Bell Helicopter Textron, Inc., “[c]ases addressing preemption in the
context of suits [related to air transportation] or airports commonly involve a state or local
government that, using its police powers, passes a law or ordinance regulating the operation of an
airport or air carrier.” 2015 WL 3542887, at *4 (Tex. App. June 4, 2015). This case, like Lewis,
instead “involves a different scenario” whereby Plaintiffs seek to use state “nuisance laws that do
not expressly mention or address aviation to regulate” the location of a heliport and the helicopter
flight paths. Id.
Defendants do not contend that Plaintiffs’ nuisance claim is entirely preempted by the
FAA. Indeed, Plaintiffs’ nuisance claim for damages is not. See, e.g., id., at *8-9 (refusing to hold
that the FAA preempted plaintiffs’ state-law nuisance claim for damages caused by helicopter
noise); Wood v. City of Huntsville, 384 So. 2d 1081, 1084-85 (Ala. 1980) (holding that a private
nuisance action related to helicopter noise was not preempted by the FAA). Rather, Defendants
argue that Plaintiffs’ requested injunctive relief is preempted. The question presented, then, is: if
Plaintiffs prove that the helicopter is a nuisance under Louisiana law, can this Court issue an
injunction requiring Defendants to relocate their helipad and reroute their helicopter flights to abate
noise? The answer is resoundingly no.
The FAA states that “[t]he United States Government has exclusive sovereignty of airspace
of the United States.” 49 U.S.C. § 40103(a)(1). The administrator of the FAA is charged with
“develop[ing] plans and policies for the use of navigable airspace and assign[ing] by regulation or
order the use of the airspace necessary to ensure the safety of aircraft136 and the efficient use of
airspace.” Id. § 40103(b)(1). That duty includes “prescrib[ing] air traffic regulations on the flight
of aircraft (including regulations on safe altitudes) for (A) navigating, protecting, and identifying
aircraft; (B) protecting individuals and property on the ground; (C) using the navigable airspace
efficiently; and (D) preventing collision between aircraft, between aircraft and land or water
vehicles, and between aircraft and airborne objects.” Id. § 40103(b)(2).
136 “Aircraft” is defined as “any contrivance invented, used, or designed to navigate, or fly in, the air.” 49
U.S.C. § 40102(a)(6). “[T]he term ‘aircraft’ includes helicopters which are designed and used to fly in the air.” United
States v. Greene, 2013 WL 5488653, at *15 (E.D. Tenn. Sept. 30, 2013).
These statutes clearly “indicate that the federal government has exclusive sovereignty over
assigning the use of the United States airspace in order to efficiently use the airspace and to protect
individuals and property on the ground.” Lewis, 2015 WL 3542887, at * 6 (citing City of Burbank,
411 U.S. at 633-34). As such, due to field preemption, this Court certainly cannot issue an
injunction requiring Defendants to change their helicopter flight paths to abate noise under the
auspice that the noise is a nuisance under Louisiana law.
The murkier question is whether this Court can issue an injunction requiring Defendants to
move the helipad if it is determined to be a nuisance. Courts have held that state and local
authorities are empowered to enact ordinances regulating the location of airports and helipads.
Hoagland v. Town of Clear Lake, 415 F.3d 693, 697 (7th Cir. 2005) (holding that “[t]he siting of
an airfield – so long as it does not interfere with existing [air] traffic patterns, etc. – remains an
issue for local control” because the court was not “convinced that Congress meant to take the siting
of air fields out of the hands of local officials”); Gustafson v. City of Lake Angelus, 76 F.3d 778,
783 (6th Cir. 1996) (distinguishing between “the United States’ sovereign regulation of the
airspace over the United States and the regulation of aircraft in flight” and “the regulation of the
designation of plane landing sites, which involves local control of land … use”); Thul v. State, 657
N.W.2d 611, 619 (Minn. App. 2003) (holding that the ordinance at issue was not preempted by
the FAA “because regulating the location of heliports has been determined to be within the
province of local governments”); City of Cleveland v. City of Brook Park, 893 F. Supp. 742, 751
(N.D. Ohio 1995) (stating that the FAA has the “authority to regulate the use of airspace, but this
does not of necessity lead to the conclusion that localities are no longer free to regulate the use of
land within their borders, even where land use regulations may have some tangential impact on
the use of airspace”); Condor Corp. v. City of St. Paul, 912 F.2d 215, 219 (8th Cir. 1990) (stating
that the court saw “no conflict between a city’s regulatory power over land use, and the federal
regulation of airspace, and ha[d] found no case recognizing a conflict”). However, this case does
not involve a state or local ordinance regarding the siting or location of a helipad. Instead,
Plaintiffs rely on a private action under Louisiana nuisance law to attempt to force Defendants to
move the helipad. In Wood v. City of Huntsville, the court upheld the issuance of an injunction
prohibiting the defendant from operating a helicopter from his home because it was determined to
be a nuisance. 384 So. 2d at 1082-85. Thus, it appears that this Court could, under state nuisance
law, enjoin Defendants from operating a helipad on their property if the equities favor Plaintiffs.
See Badke v. USA Speedway, LLC, 139 So. 3d 1117 (La. App. 2014) (upholding an injunction
prohibiting the operation of a racetrack as a nuisance); see also Par. of E. Feliciana ex rel. E.
Feliciana Par. Police Jury v. Guidry, 923 So. 2d 45, 51 (La. App. 2005) (upholding an injunction
prohibiting the operation of a motocross track as a nuisance). But Plaintiffs expressly state that
they “are not seeking to eliminate helicopter operations or impede patient care.”137 And the parties
have not cited, nor is the Court aware of, any case in which a court has issued an injunction under
state nuisance law requiring a helipad, particularly a hospital helipad, to be moved.
So what we are left with is the determination that the FAA preempts any state or local law
that would affect airspace, but it does not preempt any state or local laws regulating land use. Here,
the requested injunction – to move the helipad – would affect airspace. Although the relocated
helipad would still be on Defendants’ property, it would be in a different location and the flight
paths would necessarily be different, even if only slightly. As explained by Bertucci, Heliport
Systems, and Cianfrani, the FAA is involved in approving the location of a helipad by conducting
an aeronautical airspace study to examine whether the proposed flight paths interfere with existing
137 R. Doc. 123 at 16.
air traffic patterns.138 Depending on the results of that study, the FAA then issues a letter of
determination, either objecting or not objecting to the location of the helipad.139 Cianfrani further
states in his report that approval is not guaranteed, even for the Defendants’ old helipad, because
it has been decommissioned for five years and flight paths, airspace use, and obstructions in the
area could have changed in the interim.140 Plaintiffs have offered no countervailing evidence.
Plaintiffs try to downplay the FAA’s involvement in the approval of helipad locations by labeling
the application and approval process as “straightforward,” but they admit that the FAA is involved
in reviewing flight paths.141 Plaintiffs position seems to be that the Court should be able to issue
the requested injunction because FAA will likely allow a helipad relocation to the former site as,
in their view, that would involve minimal change to the flight paths. However, the amount of
change to the flight paths – especially from a lay vantage point – is immaterial. The FAA would
still need to be involved in determining that the flight paths to and from the relocated helipad do
not conflict with other airspace use. And it is this impingement on airspace that is fatal to
Plaintiffs’ injunction request. See Lewis, 2015 WL 3542887, at *7 (holding that a court cannot
compel a new flight path as a remedy for nuisance through the application of state law because the
federal government occupies the field of flight path regulation). Accordingly, Defendants’ motion
for summary judgment is granted as to Plaintiffs’ request for injunctive relief, and that claim is
DISMISSED WITH PREJUDICE.

3. Nuisance claim for damages
a. Viability of the claim
Defendants argue that Plaintiffs’ nuisance claim fails as a matter of law.142 Defendants say
that they cannot be liable for nuisance because Louisiana Civil Code article 669 “only allows
suppression of certain inconveniences if they are excessive under local ordinances or customs,”
and their helicopter, as an emergency vehicle, is exempt from the city noise ordinance, meaning
that Plaintiffs cannot prove that the helicopter noise is excessive under a local ordinance or
custom.143 Defendants also point out that Plaintiffs’ sound expert, Bommer, did not calculate the
noise from the Defendants’ helicopter operations in light of the city noise ordinance, and that the
New Orleans Department of Health has opined that the helicopter is exempt from the ordinance
when it is responding to an emergency.144 Defendants further contend that “[t]he FAA regulates
permissible levels of noise from general aviation operations, and it is undisputed that the noise
emanating from [their] heliport and helicopter is well within the levels permitted by the FAA.”145
Defendants support that argument by citing to the opinions of their sound expert, Reindel, and the
testimony of Heliport Systems, which was the company involved in designing the heliport.146 In
summary, Defendants conclude that “Plaintiffs’ nuisance claim must be dismissed as a matter of
law,” because, “[a]t most, the alleged noise emanating from the helicopter is nothing more than an
inconvenience permissible under [article] 669.”147
Plaintiffs respond in opposition, arguing that the FAA regulations do not establish a
permissible noise threshold for hospital helicopter operations and, in their view, Bommer’s method

143 Id. at 16, 18-19 (emphasis in original).

appropriately measured the impact of the helicopter noise on the neighborhood.148 Plaintiffs also
argue that Defendants’ helicopter is exempt from the city noise ordinance only when it is
responding to emergencies, and Defendants have not identified “which specific flights were true
emergency responses and which were not,” meaning that, in Plaintiffs’ view, “Defendants cannot
establish as a matter of law that the [city] [n]oise [o]rdinance is inapplicable.”149 Plaintiffs further
contend that Defendants’ “compliance with zoning or noise regulations does not immunize their
operations from nuisance liability,” and “[w]hether the helicopter operations at issue rise to [the]
level [of nuisance] requires a fact-intensive inquiry,” which precludes summary judgment.150
Additionally, Plaintiffs assert that there are disputed issues of material fact concerning whether
Defendants knew or should have known that relocating the helipad to its current location would
cause Plaintiffs real damages or excessive inconvenience.151
In their reply, Defendants reassert that Plaintiffs’ nuisance claim fails as a matter of law
because Defendants have “firmly established that any noise is not excessive under local ordinances
and customs” and Plaintiffs have not presented any evidence to show that it is.152 Defendants also
reurge that courts have adopted the FAA’s method for calculating noise, as have Reindel and
Heliport Systems.153 Further, Defendants point out that Plaintiffs have not “cite[d] to any record
evidence to describe or measure the noise [about] which Plaintiffs complain.”154
In their surreply, Plaintiffs contest Defendants’ assertion that courts, Reindel, and Heliport
Systems have accepted the FAA’s method for calculating noise but insist, nonetheless, that any

154 Id. at 7.
such acceptance by a court does not apply to preclude “state-law nuisance claims against a
privately owned helipad.”155
In their sur-surreply, Defendants once again say that Plaintiffs’ nuisance claim fails as a
matter of law because they do not “present any reliable and valid evidence that the aviation noise
they complain of is excessive under local ordinance or custom as required by Louisiana nuisance
law.”156 They also reurge that the DNL is the proper standard for measuring aviation noise, as
attested by Reindel and Heliport Systems.157
Claims for nuisance are governed by the vicinage articles 667 through 669 of the Louisiana
Civil Code. Article 667 states in pertinent part:
Although a proprietor may do with his estate whatever he pleases, still he cannot
make any work on it, which may deprive his neighbor of the liberty of enjoying his
own, or which may be the cause of any damage to him. However, if the work he
makes on his estate deprives his neighbor of enjoyment or causes damage to him,
he is answerable for damages only upon a showing that he knew or, in the exercise
of reasonable care, should have known that his works would cause damage, that the
damage could have been prevented by the exercise of reasonable care, and that he
failed to exercise such reasonable care.
La. Civ. Code art. 667. Article 668, however, appears to place a limit on the conduct actionable
under article 667, as it implies that mere inconvenience is noncognizable: “Although one be not at
liberty to make any work by which his neighbor’s buildings may be damaged, yet every one has
the liberty of doing on his own ground whatsoever he pleases, although it should occasion some
inconvenience to his neighbor.” Id. art. 668. Finally, notwithstanding article 668’s seeming
tolerance of inconveniences, article 669 states:
If the works or materials for any manufactory or other operation, cause an
inconvenience to those in the same or in the neighboring houses, by diffusing
smoke or nauseous smell, and there be no servitude established by which they are
155 R. Doc. 134 at 5-6 (quote at 6).

157 Id. at 3-4.
regulated, their sufferance must be determined by the rules of the police, or the
customs of the place.
Id. art. 669.
Louisiana’s vicinage articles thus “‘embody a balancing of rights and obligations
associated with the ownership of immovables.’” Ellis v. Evonik Corp., 604 F. Supp. 3d 356, 374
(E.D. La. 2022) (quoting Badke, 139 So. 3d at 1126). While a landowner has wide latitude to
“‘exercise his rights of ownership in any manner he sees fit’” and may subsequently cause some
inconvenience to neighbors, activities cannot cause “‘real damage to his neighbor.’” Id. (quoting
Badke, 139 So. 3d at 1126). Article 667 “prohibits uses which cause damage to neighbors or
deprive them of the enjoyment of their property, while [article] 668 permits uses which merely
cause neighbors some inconvenience. [Article] 669 allows suppression of certain inconveniences
if excessive under local ordinances or customs, and requires tolerance of lesser inconveniences.”
Barrett v. T.L. James & Co., 671 So. 2d 1186, 1190 (La. App. 1996). “A finding of liability under
[a]rticle 667 requires either proof of personal injury or physical damage to property or proof of the
presence of some type of excessive or abusive conduct.” Myers v. Union Carbide Corp., 2022
WL 17092121, at *4 (E.D. La. Nov. 21, 2022) (quotation and alteration omitted).
“With the exception of the ‘ultrahazardous’ activities of pile driving and blasting with
explosives – neither of which is at issue here – a claim under any or all of these three Code articles
requires a showing of negligence.” Id. Thus, to prevail on a nuisance claim under any or all of
these articles, a plaintiff must prove that “a defendant is: (1) a proprietor who (2) negligently (3)
conducts ‘work’ on his property (4) that causes damage to his neighbor.” Ictech-Bendeck v.
Progressive Waste Sols. of LA, Inc., 2019 WL 4111681, at *2 (E.D. La. Aug. 29, 2019).
In analyzing whether conduct is excessive or abusive, i.e., more than an inconvenience, a
court must determine the reasonableness of the conduct in light of the circumstances including
“the character of the neighborhood, the degree of the intrusion and the effect of the activity on the
health and safety of the neighbors.” Rodrigue v. Copeland, 475 So. 2d 1071, 1077 (La. 1985).
“[W]hether an inconvenience is excessive or not is to be determined in the light of local ordinances
and customs.” Barrett, 671 So. 2d at 1191. But “local nuisance ordinances must be construed in
reference to the applicable civil code provisions.” Par. of E. Feliciana, 923 So. 2d at 51.
Moreover, for noise to constitute a nuisance that is subject to an action for damages, the noise must
be “excessive, unreasonable in degree, and of such character as to produce actual physical
discomfort and annoyance to a person of ordinary sensibilities.” King v. W. Club, Inc., 587 So. 2d
122, 124 (La. App. 1991). “When the actions or work cease to be inconveniences and become
damaging is a question of fact.” Badke, 139 So. 3d at 1126.
Defendants hinge their argument that Plaintiffs’ nuisance claim fails as a matter of law on
the premise that Plaintiffs must, and cannot, prove that Defendants violated a local ordinance or
custom.158 This is not what Louisiana nuisance law requires. Nowhere does Louisiana law provide
that compliance with a noise ordinance provides an escape hatch to a nuisance claim. However,
while a city ordinance or permit cannot validate a nuisance or, conversely, invalidate a nuisance
claim, Meyer v. Kemper Ice Co., 158 So. 378, 381 (La. 1934), a court “must consider” the zoning
and planning standards as one of several relevant factors in determining whether an alleged
nuisance exists. Jones v. Capitol Enters., 89 So. 3d 474, 508 (La. App. 2012) (stating that among
the relevant factors are “[t]he place where the activity occurs,” which includes “consider[ing] the
neighborhood, zoning and planning standards, environmental goals”). Indeed, under Louisiana
law, whether an inconvenience is so excessive as to rise to the level of a nuisance is evaluated in
light of numerous factors that include not only local ordinances and customs, but also the character
158 R. Doc. 106-1 at 15-20.
of the neighborhood, the degree of intrusion, the effect of the activity on the health and safety of
the neighbors, and whether it causes actual physical discomfort and annoyance to a person of
ordinary sensibilities. See Barrett, 671 So. 2d at 1191; Rodrigue, 475 So. 2d at 1077; King, 587
So. 2d at 124. In short, the Defendants’ compliance (or not) with the city noise ordinance is one
factor that will be considered by the factfinder in determining whether their helicopter is a
nuisance. The same is true of the FAA aviation noise standard. Defendants have not shown that
this standard applies in such a way as to negate a state-law nuisance claim arising from the
operation of a private helicopter.159 Thus, Defendants’ compliance with the FAA standard, as with
the city noise ordinance, is a factor to be evaluated in determining whether their helicopter
operations constitute a nuisance. At this juncture, viewing the evidence in the light most favorable
to Plaintiffs, they have identified sufficient disputed issues of material fact (e.g., their own
experiences with the noise) to defeat Defendants’ motion for summary judgment on their nuisance
claim for damages.
b. Damages
Defendants argue that Plaintiffs cannot recover damages for personal injuries, including
(1) hearing loss, (2) sleep disturbance, (3) mental health issues, (4) physical and mental suffering,
(5) past, present, and future medical expenses, and (6) past, present, and future mental pain and
suffering, because “Plaintiffs have failed to identify or disclose any retained or non-retained
experts to offer expert general or specific causation testimony for their alleged medical injuries.”160
Defendants also contend that Plaintiffs cannot recover for diminution of property value and
159 Defendants cite Seattle Cmty. Council Fed’n, 961 F.2d at 834-35, for the proposition that “courts have
consistently upheld this FAA standard [i.e., the DNL] to measure noise impacts from aviation operations.” R. Doc.
125 at 7-8. While the DNL standard is one way to measure noise, Defendants have not cited, nor is the Court aware
of, any case establishing that the DNL is the only way to measure aviation noise, particularly in the context of a state-
law nuisance claim.
160 R. Doc. 106-1 at 22-23 (quote at 23).
property damage because they “did not disclose a real estate expert and have no evidence to
establish the diminution of value to [their] residences.”161 Lastly, Defendants argue that Plaintiffs
cannot recover damages for the cost to remediate their properties because they “have no expert
who can opine on what sound remediation is needed for each of the three homes, the costs, and the
success of such remediation.”162 To that end, Defendants observe that Plaintiffs listed an architect
(Hackenberg) and contractor (Rau) on their witness list, but failed to properly designate them as
retained or non-retained experts, and “there has been no disclosure on how much if any [of] the
cost [Plaintiffs incurred] was for sound remediation as opposed to other construction work,
including adding on a bedroom, bathroom, and replacing the electrical and plumbing.”163
Plaintiffs did not address these arguments in their summary-judgment response.164 They
thus concede that they cannot prevail on these items of damages. See Magee v. Life Ins. Co. of N.
Am., 261 F. Supp. 2d 738, 748 n.10 (S.D. Tex. 2003) (stating that “failure to brief an argument in
the district court waives that argument in that court”); see also Kellam v. Metrocare Servs., 2013
WL 12093753, at *3 (N.D. Tex. May 31, 2013) (“Generally, the failure to respond to arguments
constitutes abandonment or waiver of the issue.” (quotation omitted)), aff’d, 560 F. App’x 360
(5th Cir. 2014). Moreover, in ruling on Defendants’ motion in limine this Court held that Plaintiffs
failed to properly disclose retained or non-retained experts to address these issues. Accordingly,
Plaintiffs’ claims for damages related to: (A) personal injuries, including (1) hearing loss, (2) sleep
disturbance, (3) mental health issues, (4) physical and mental suffering, (5) past, present, and future
medical expenses, and (6) past, present, and future mental pain and suffering; (B) diminution of

164 See R. Doc. 123.
property value; (C) property damage; and (D) the cost to remediate their properties, are
DISMISSED WITH PREJUDICE.165
4. Negligence
Defendants assert that Plaintiffs’ negligence claim must be dismissed because it is not an
independent general negligence claim, but rather a nuisance-negligence claim that is subsumed by
Plaintiffs’ claim under the vicinage articles.166 In response, Plaintiffs affirm that they “have not
asserted a stand-alone negligence claim under article 2315, but rather a nuisance claim under Civil
Code articles 667-669, which incorporates negligence as a component.”167
Under Louisiana law, “[i]t is well established [that] any negligence action based on the
vicinage articles is governed by the same duties and considerations as a direct action under those
Code [a]rticles. In other words, whether it is called a negligence action or an action under 667-
669, the same legal standards apply.” Yokum v. Pat O’Brien’s Bar, Inc, 2023 WL 11893172, at
*5 (La. Dist. Ct. May 24, 2023). And while “there is a distinction between a general negligence
claim under article 2315 and the distinct negligence requirements for a nuisance claim under the
vicinage articles,” id. (citing LeBouef v. Evonik Corp., 620 F. Supp. 3d 463, 474 (E.D. La. 2022)),
because Plaintiffs admit that they allege only a nuisance-negligence action under the vicinage
articles, any negligence claim purportedly stated in the complaint is DISMISSED WITH
PREJUDICE.
165 What remains to be tried is Plaintiffs’ nuisance claim for damages related to loss of use of their property
and inconvenience. See R. Doc. 1-1 at 10.
166 R. Doc. 106-1 at 20-22.
167 R. Doc. 123 at 20. Defendants acknowledge Plaintiffs’ admission in their reply but argue that the claim
should also be dismissed because Plaintiffs cannot prevail on a nuisance claim. R. Doc. 125 at 9.
III. CONCLUSION
Accordingly, for the foregoing reasons,
IT IS ORDERED that Defendants’ motion in limine to exclude Bommer’s opinions and
testimony from trial (R. Doc. 105) is GRANTED as to excluding Bommer’s testimony and
opinions regarding property valuation, health effects and sleep disturbances caused by noise,
residential sound modifications, and aviation-related topics, such as the feasibility of moving the
helipad back to its old location, changing flight paths, or using the helipad only for specific
purposes. The motion is otherwise DENIED.
IT IS FURTHER ORDERED that Defendants’ motion in limine to exclude any other
retained or non-retained experts from offering opinions for Plaintiffs at trial (R. Doc. 105) is
GRANTED. However, these witnesses (i.e., Melisa Rey’s healthcare providers and therapists,
Hackenberg, and Rau) may testify as fact witnesses, if appropriate.
IT IS FURTHER ORDERED that Defendants’ motion for summary judgment (R. Doc.
106) is GRANTED as to dismissing Plaintiffs’ claim for injunctive relief, which is DISMISSED
WITH PREJUDICE.
IT IS FURTHER ORDERED that Defendant’s motion for summary judgment (R. Doc.
106) is DENIED as to dismissing Plaintiffs’ nuisance claim for damages, generally.
IT IS FURTHER ORDERED that Defendant’s motion for summary judgment (R. Doc.
106) is GRANTED as to dismissing Plaintiffs’ stand-alone negligence claim, and that claim is
DISMISSED WITH PREJUDICE.
IT IS FURTHER ORDERED that Defendants’ motion for summary judgment (R. Doc.
106) is GRANTED as to dismissing Plaintiffs’ claims for damages related to: (A) personal injuries,
including (1) hearing loss, (2) sleep disturbance, (3) mental health issues, (4) physical and mental
suffering, (5) past, present, and future medical expenses, and (6) past, present, and future mental
pain and suffering; (B) diminution of property value; (C) property damage; and (D) the cost to
remediate their properties, and those claims are DISMISSED WITH PREJUDICE.
