v. 

FEDERAL AVIATION ADMINISTRATION, 

Defendant.

Civil Action No. 19-3749 (CKK) 

MEMORANDUM OPINION

(September 16, 2021) 

This lawsuit arises from a Freedom of Information Act (“FOIA”) request made by Plaintiffs 

Paul Hudson and Flyers Rights Education Fund, Inc. (“FlyersRights”) to Defendant Federal 

Aviation Administration (“FAA”). FlyersRights requested records pertaining to the FAA’s review 

of design changes to the The Boeing Company’s 737 MAX (“737 MAX”) in the wake of two fatal 

crashes involving that aircraft. 

Presently before the Court are FlyersRights’ [21] Motion for Summary Judgment and the 

FAA’s [23] Cross-Motion for Summary Judgment. Upon consider of the pleadings,1

 the relevant 

legal authorities, and the record as a whole, for the reasons stated below, the Court finds that the 

FAA has satisfied its burden to demonstrate that it properly withheld records pursuant to FOIA 

1

 The Court’s consideration has focused on the following: Plaintiffs’ Memorandum of Points & Authorities in Support 

of Motion for Summary Judgment (“Pls.’ Mot. for S.J.”), ECF No. 21-1; Plaintiffs’ Statement of Material Facts as to 

Which There is No Genuine Dispute (“Pls.’ Stmt.”), ECF No, 21-2; Combined Memorandum of Points & Authorities 

in Support of Defendant’s Cross-Motion for Summary Judgment and Opposition to Plaintiffs’ Motion for Summary 

Judgment (“Def.’s Cross-Mot. & Opp’n”), ECF No. 23-4; Defendant’s Statement of Material Facts as to Which There

Exemption 4, and so shall GRANT the FAA’s Cross-Motion for Summary Judgement and DENY

FlyersRights’ Motion for Summary Judgment. 

I. BACKGROUND 

A. Factual Background 

The 737 MAX is a twin-engine jet airplane manufactured by The Boeing Company 

(“Boeing”). Def.’s Stmt. ¶ 1. On October 29, 2018, a 737 MAX operated by Lion Air on Flight 

JT610 crashed after taking off from Jakarta, Indonesia, killing 189 passengers and crew members. 

Pls.’ Stmt. ¶ 1; Def.’s Resp. Stmt. ¶ 1. On March 10, 2019, a 737 MAX operated by Ethiopian 

Airlines on Flight ET302 similarly crashed after takeoff from Addis Ababa, Ethiopia, killing 157 

passengers and crewmembers. Pls.’ Stmt. ¶ 1; Def.’s Resp. Stmt. ¶ 1. 

Shortly after the second crash, on March 13, 2019, the FAA issued an emergency order 

prohibiting operation of 737 MAX series airplanes within the territory of the United States and by 

United States “certificated operators.” Pls.’ Stmt. ¶ 2; Def.’s Resp. Stmt. ¶ 2; see Operators of 

Boeing Company Model 737-8 and Boeing Company Model 737-9 Airplanes: Emergency Order 

of Prohibition, 84 Fed. Reg. 9,705 (Mar. 18, 2019). The FAA’s emergency order noted that “some 

similarities” between these two accidents “warrant[ed] further investigation of the possibility of a 

shared cause for the two incidents that needs to be better understood and addressed.” Id. at 9,706. 

The FAA, which is responsible for the safety and certification of all civil aircraft 

manufactured and operated in the United States, “instructed Boeing to make certain design changes 

to the 737 MAX.” Def.’s Stmt. ¶¶ 1, 2; Declaration of Susan Cabler (“Cabler Decl.”) ¶ 7, ECF 

No. 23-5; see also Pls.’ Stmt. ¶ 10. When “a manufacturer makes a major design change to an 

aircraft model with an existing type certificate,” it must obtain from the FAA an “amended type 

certificate.” Cabler Decl. ¶¶ 14, 15. In general terms, the certification process for an airplane 
3 

design change requires applicants to “show that the changed design complies with the applicable 

regulations and standards, to provide the means by which such compliance has been shown, and 

to submit a statement certifying compliance with applicable requirements.” Id. ¶ 17 (citing 14 

C.F.R. § 21.20). According to the FAA, proposed design changes by aircraft manufacturers “often 

consist of information the applicant considers trade secrets or proprietary commercial 

information.” Id.; see Def.’s Stmt. ¶ 3. 

B. Procedural Background 

FlyersRights submitted a FOIA request dated October 31, 2019 to the FAA, seeking 

records concerning the FAA’s review of Boeing’s design changes to the 737 MAX following the 

Lion Air and Ethiopian Air crashes. Pls.’ Stmt. ¶ 15; Def.’s Stmt. ¶ 5. Specifically, FlyersRights 

requested the following records on an expedited basis: 

• Records of all software changes, including [Maneuvering Characteristics 

Augmentation System (“MCAS”)], that Boeing has submitted to the FAA for 

the 737 MAX since October 28, 2019. 

• All software changes for the Boeing 737 MAX, including MCAS, that were 

proposed, required, or requested by the FAA since October 28, 2019. 

• Records describing and analyzing the flaws or needed adjustments to MCAS 

and other 737 MAX software. 

• Records describing the solutions or fixes to the aforementioned flaws that were 

either (1) proposed by the FAA, Boeing, [Joint Authorities Technical Review 

(“JATR”)], [Technical Advisory Board (“TAB”)], or any other federal 

government entity, (2) requested or required by FAA, JATR, TAB, or other 

federal government entity, (3) submitted to FAA, JATR, or TAB by Boeing. 

• Any cost-benefit analysis of grounding and ungrounding the 737 MAX either 

(1) conducted by the FAA or (2) submitted to the FAA by Boeing, [Aerospace 

Industries Association (“AIA”)], or any other party. 

• Records confirming whether a cost-benefit analysis has or has not been (1) 

conducted by the FAA, or (2) submitted to the FAA by Boeing or any other 

interested party.

Cabler Decl. Ex 1, at Cabler 000100. On December 16, 2019, FlyersRights initiated this action to 

compel the FAA to produce the requested records on an expedited basis. Pls.’ Stmt. ¶ 16; Def.’s 

Resp. Stmt. ¶ 16. Soon thereafter, on December 23, 20219, FlyersRights filed a motion for a 

preliminary injunction, seeking to compel its request for expedited processing. See Pls.’ Mot. for 

Prelim. Inj., ECF No. 3. 

The FAA performed an initial search for records responsive to FlyersRights’ FOIA request 

and identified 49,000 pages of responsive materials. Pls.’ Stmt. ¶ 17; Def.’s Resp. Stmt. ¶ 17; see

Joint Status Rep. (Jan. 13, 2020) at 1, ECF No. 8. The parties subsequently conferred and 

FlyersRights agreed to narrow its FOIA request to focus on those records upon which the FAA 

would rely in considering the 737 MAX’s “return to service.” Pls.’ Stmt. ¶ 17; Def.’s Resp. Stmt. 

¶ 17. The FAA reported that 86 records comprising 9,443 pages were responsive to this narrowed 

request. Pls.’ Stmt. ¶ 17; Def.’s Resp. Stmt. ¶ 17; Joint Status Rep. (Jan. 21, 2020), ECF No. 9. 

The Court ordered the FAA to provide Plaintiff with a list of the 86 responsive records, indicating 

the “title, author, recipient, date, and number of pages for each document.” See Minute Order (Jan. 

21, 2020). The Court also ordered FlyersRights to submit a status report, informing the FAA and 

the Court of its requested “prioritization of these documents.” Id. Both parties complied with 

these directives, see Pls.’ Status Rep., ECF No. 10, and Plaintiffs subsequently withdrew the 

motion for a preliminary injunction, see Pls.’ Mot. to Withdraw P.I. Mot., ECF No. 14; Minute 

Order (Mar. 6, 2020). 

The Court also required the FAA to provide to Boeing the documents it had identified as 

responsive to FlyersRights’ FOIA request, and directed that “Boeing shall indicate to [the FAA] 

over which documents it has objections and over which documents it has no objections.” Order, 

ECF No. 11. In a joint report dated March 20, 2021, the FAA indicated that it had provided the 
5 

documents to Boeing, and requested that Boeing identify “(1) which of the documents contain 

confidential trade secrets or commercial/financial information that it objects to releasing and (2) 

which of the documents it has no objections.” Joint Progress Rep. (Mar. 20, 2021) ¶ 1, ECF No. 

15. In response, Boeing identified 76 documents for which “it objects to the release of information 

falling under FOIA Exemption 4.” Id. ¶ 2. In the same report, the FAA indicated that it had 

produced to FlyersRights four documents in full and sixteen documents with names of Boeing 

employees redacted pursuant to FOIA Exemption 6. See id. ¶ 3; Pls.’ Stmt. ¶ 20; Def.’s Resp. 

Stmt. ¶ 20. 

As of September 2020, the FAA produced to FlyersRights the remaining responsive 

records, “all of which were redacted almost in their entirety except for cover memos and transmittal 

letters.” Pls.’ Stmt. ¶ 21; Def.’s Resp. Stmt. ¶ 21. On October 9, 2020, the FAA filed a Vaughn 

Index listing 108 documents. See Vaughn Index, ECF No. 19-1. Of the 108 documents, the FAA 

released five documents in full with no redactions, released 22 documents with redactions to 

“Boeing lower-level names” under Exemption 6, released 38 documents with redactions pursuant 

to Exemption 4 or a combination of Exemptions 4 and 6, and withheld in full 37 documents in full 

pursuant to Exemption 4 or a combination of Exemptions 4 and 6. See Cabler Decl. ¶ 11; Vaughn 

Index. 

 The FAA filed contemporaneously with its Vaughn Index a declaration of Jeffrey Allen, a 

paralegal in Boeing’s Law Department. See Declaration of Jeffrey Allen (“Allen Decl.”), ECF 

No. 19-2. Mr. Allen indicates that based on Boeing’s review of the records identified by the FAA 

as responsive to FlyersRights’ FOIA request, “Boeing has concluded that the majority of 

documents requested by Plaintiffs contain trade secrets and other proprietary commercial 

information that Boeing customarily and actually treats as private and that Boeing provided to the 

7 

Susan Cabler, the Deputy Director in the FAA’s Certification Service, Cabler Decl. ¶ 1, a 

Declaration of David Polland, Director of Product and Services Safety at Boeing, see Declaration 

of David Polland (“Polland Decl.”) ¶ 1, ECF No. 23-6 and a Declaration of Earl Lawrence, the 

Executive Director of the FAA’s Certification Service, see Declaration of Earl Lawrence 

(“Lawrence Decl.”) ¶ 1, ECF No. 23-7. The FAA contends that it is entitled to summary judgment 

because each of the above-listed records contains “confidential commercial information” obtained 

from Boeing, for which it properly invoked the protection of FOIA Exemption 4. See Def.’s CrossMot. & Opp’n at 6; Cabler Decl. ¶ 19 (the above-listed records comprise “highly technical 

documents that heavily incorporate proprietary information about Boeing’s certification-related 

processes and technical data, and provide detailed descriptions of how the specific 737 MAX 

design changes comply with applicable regulations and standards”). The parties’ cross-motions 

are fully briefed and ripe for the Court’s consideration. 

II. LEGAL STANDARD 

Congress enacted the Freedom of Information Act, 5 U.S.C. § 552, to “pierce the veil of 

administrative secrecy and to open agency action to the light of public scrutiny.” Dep’t of Air 

Force v. Rose, 425 U.S. 352, 361 (1976) (citation omitted). Congress remained sensitive to the 

need to achieve balance between these objectives and the potential that “legitimate governmental 

and private interests could be harmed by release of certain types of information.” Critical Mass 

Energy Project v. Nuclear Regulatory Comm’n, 975 F.2d 871, 872 (D.C. Cir. 1992) (en banc) 

(citation omitted), cert. denied, 507 U.S. 984 (1993). To that end, FOIA “requires federal agencies 

to make Government records available to the public, subject to nine exemptions for categories of 

material.” Milner v. Dep’t of Navy, 131 S. Ct. 1259, 1261–62 (2011). Ultimately, “disclosure, not 

secrecy, is the dominant objective of the act.” Rose, 425 U.S. at 361. For this reason, the 
8 

“exemptions are explicitly made exclusive, and must be narrowly construed.” Milner, 131 S. Ct. 

at 1262 (citations omitted). 

When presented with a motion for summary judgment in this context, the district court 

must conduct a “de novo” review of the record, which requires the court to “ascertain whether the 

agency has sustained its burden of demonstrating that the documents requested . . . are exempt 

from disclosure under the FOIA.” Multi Ag. Media LLC v. Dep’t of Agriculture, 515 F.3d 1224, 

1227 (D.C. Cir. 2008) (citation omitted). The burden is on the agency to justify its response to the 

plaintiff’s request. 5 U.S.C. § 552(a)(4)(B). “An agency may sustain its burden by means of 

affidavits, but only if they contain reasonable specificity of detail rather than merely conclusory 

statements, and if they are not called into question by contradictory evidence in the record or by 

evidence of agency bad faith.” Multi Ag Media, 515 F.3d at 1227 (citation omitted). “If an 

agency’s affidavit describes the justifications for withholding the information with specific detail, 

demonstrates that the information withheld logically falls within the claimed exemption, and is not 

contradicted by contrary evidence in the record or by evidence of the agency’s bad faith, then 

summary judgment is warranted on the basis of the affidavit alone.” Am. Civil Liberties Union v. 

Dep’t of Defense, 628 F.3d 612, 619 (D.C. Cir. 2011) (citations omitted). “Uncontradicted, 

plausible affidavits showing reasonable specificity and a logical relation to the exemption are 

likely to prevail.” Ancient Coin Collectors Guild v. Dep’t of State, 641 F.3d 504, 509 (D.C. Cir. 

2011) (citation omitted). Summary judgment is proper when the pleadings, the discovery materials 

on file, and any affidavits or declarations “show[] that there is no genuine dispute as to any material 

fact and the movant is entitled to judgment as a matter of law.” Fed. R. Civ. P. 56(a). With these 

principles in mind, the Court turns to the merits of the parties’ cross-motions for summary 

judgment.

III. DISCUSSION 

FOIA Exemption 4 shields from disclosure “trade secrets and commercial or financial 

information obtained from a person and privileged or confidential.” 5 U.S.C. § 552(b)(4). 

FlyersRights argues that the FAA has not satisfied its burden to demonstrate that all of the 

withheld records are “confidential.” FlyersRights also contends that the FAA has failed to 

demonstrate that documents in the category of “FAA comments” were “obtained from a person.” 

The Court shall address each issue in turn, beginning with the latter challenge, which implicates 

only a handful of records. 

A. The FAA Has Demonstrated that the Withheld Records Were “Obtained from a 

Person.” 

FlyersRights argues that four documents listed on the Vaughn Index (Documents 41, 45, 

50, and 83) contain “comments by the FAA,” which do not meet Exemption’s 4 requirement that 

the information was “obtained from a person.” Pls.’ Mot. for S.J. at 27. FlyersRights also contends 

that Document 32, which contains comments by the European Union for Aviation Safety Agency 

(“EASA”) should be disclosed because “although EASA could be a ‘person,’” it did not have “any 

objection” on the record to “disclosure of its comments.” Id. at 28. The FAA argues that all of 

these disputed records contain information obtained directly from Boeing, satisfying Exemption 

4’s requirement that it was obtained from “a person.” See Def.’s Cross Mot. & Opp’n at 17–19. 

The Court concludes that FAA has demonstrated that the information at issue in these five records 

was “obtained from a person,” (Boeing) as required by FOIA Exemption 4. 5 U.S.C. § 552(b)(4). 

“Person” is defined in FOIA to include corporations, partnerships, associations, and other 

private organizations. See 5 U.S.C. § 551(2). FlyersRights correctly notes that information 

“generated within the Government” is not “obtained from a person” and therefore cannot qualify 

for Exemption 4. Pls.’ Mot. for S.J. at 27 (citing Ctr. for Auto Safety v. Dep’t of Treasury, 133 F. 
10 

Supp. 3d 109, 120 (D.D.C. 2015) (additional citations omitted)); see also S. All. for Clean Energy 

v. Dep’t of Energy, 853 F. Supp. 2d 60, 68 (D.D.C. 2012) (explaining that information that 

“constitutes that agency’s own analysis” is “the agency’s information, and not ‘obtained from a 

person’ under Exemption 4”). However, “information originally obtained from an outside source 

but later included in agency documents, may be considered ‘obtained from a person.’” COMPTEL 

v. FCC, 910 F. Supp. 2d 100, 117 (D.D.C. 2012). “[I]nformation in an agency-generated 

[document] is still ‘obtained from a person’ if such information was supplied to the agency by a 

person or could allow others to ‘extrapolate’ such information.” Ctr. for Auto Safety, 133 F. Supp. 

at 123 (internal citations and quotation marks omitted); see also Judicial Watch, Inc. v. ExportImport Bank, 108 F. Supp. 2d 19, 28 (D.D.C. 2000) (“[D]ocuments prepared by the federal 

government may be covered by Exemption 4 if they contain summaries or reformulations of 

information supplied by a source outside of the government.”). 

FlyersRights argues that the Vaughn Index entries for Documents 41, 45, 50, and 83 

describe “FAA comments,” which are “generated by the government,” and therefore not provided 

by a “person.” Pls.’ Mot. for S.J. at 27–28. The FAA responds that these comments addressed 

information that was provided “directly from a Boeing employee acting on behalf of Boeing.” 

Def.’s Cross-Mot. & Opp’n at 17. In support of its argument, the FAA cites Ms. Cabler’s 

declaration, in which she attests that the “seventy-nine pages withheld in their entirety [Documents 

45 and 50] consisted of charts created through collaboration by Boeing and FAA,” containing 

“FAA comments to Boeing’s project deliverables,” which “would reveal technical data and 

Boeing’s proprietary methods of compliance if released.” Cabler Dec. ¶ 51. Ms. Cabler further 

states that, with respect to the eight pages produced with redactions (Documents 41 and 83), the 

FAA redacted only the information that originated with Boeing. Id. The Court finds that the FAA 
11 

has provided sufficient information to conclude that these “FAA comments” involve information 

“obtained from” Boeing, the disclosure of which “could allow others to extrapolate” Boeing’s 

information. Ctr. for Auto Safety, 133 F. Supp. at 123. Accordingly, the FAA has satisfied its 

obligation to demonstrate that the information at issue in Documents 41, 45, 50, and 83 meets the 

“obtained from a person” requirement of Exemption 4. 

With respect to Document 32, which includes “EASA comments,” FlyersRights argues 

only that “there is no evidence” that “EASA had any objection to the disclosure of its comments” 

Pls.’ Mot. for S.J. at 28. The FAA responds that the withheld page “was not authored by EASA, 

but is rather Boeing’s description of EASA comments to Boeing’s certification documentation, 

and steps that Boeing took to address these comments.” Def.’s Cross-Mot. & Opp’n at 18–19 

(citing Cabler ¶ 52). The FAA’s description, in its Vaughn Index and supporting affidavit of Ms. 

Cabler, establishes that this information was generated by Boeing, not the government and 

therefore satisfies the “obtained from a person” requirement of Exemption 4. 

The Court turns next to FlyersRights’ primary argument in support of its motion for 

summary judgment—that the FAA has failed to demonstrate that the withheld records are 

“confidential.” 

B. The FAA Has Demonstrated that the Withheld Records Are “Confidential.” 

FlyersRights argues that it is entitled to summary judgment because the FAA has failed to 

demonstrate that the withheld records are “confidential.” The Supreme Court recently considered 

the meaning of “confidential” in FOIA Exemption 4, concluding “commercial or financial” 

information is “confidential” “at least where” it is “[1] both customarily and actually treated as 

private by its owner [2] and provided to the government under an assurance of privacy.” Food 

Marketing Inst. v. Argus Leader Media, 139 S. Ct. 2356, 2366 (2019). The Court shall address the 

parties’ arguments with respect to each prong of the Supreme Court’s test. 
12 

1. Customarily and Actually Treated as Private by Its Owner. 

FlyersRights does not appear to dispute that FAA has satisfied the first prong of the Food 

Marketing test—that the withheld information was “both customarily and actually treated as 

private” by Boeing. Id. FlyersRights does, however, contend that two categories of withheld 

information—“means of compliance” and “safety analyses”—involve public information, and so 

cannot be “confidential” within the meaning of Exemption 4. See Pls.’ Mot. for S.J. at 18, 21. 

Accordingly, the Court briefly addresses the arguments as to these two categories, as they appear 

to fall within the first prong of the Food Marketing test. 

Whether information is “customarily and actually treated as private by its owner” turns on 

“how the particular party customarily treats the information, not how the industry as a whole treats 

the information.” Ctr. for Auto Safety v. Nat’l Highway Traffic Safety Admin., 244 F.3d 144, 148 

(D.C. Cir. 2001) (emphases added) (citing Critical Mass Energy, 975 F.2d at 872, 878–80). 

FlyersRights contends that the information contained in the “means of compliance” 

category is publicly available, and therefore “cannot be proprietary.” Pls.’ Mot. for S.J. at 18. 

FlyersRights indicates that “means of compliance” are “standard specifications and testing used 

by an aircraft manufacturer to demonstrate compliance with FAA regulations,” most of which “are 

publicly available.” Id. The FAA acknowledges that some “means of compliance” methods are 

publicly available and that applicants for certification can “choose to use these publicly available 

methods to show compliance.” Cabler Decl. ¶ 29. But applicants can also “develop their own 

means of compliance that are specific to their airplane design, which is not publicly available” 

because “an applicant’s design will dictate how compliance will be shown[.]” Id. ¶¶ 26, 29 

(emphasis added). In such cases, manufacturers maintain “means of compliance” as “confidential 

business information or trade secret information” because it is specific to a particular design. Id. 
13 

Ms. Cabler indicates in her declaration that Boeing did not use publicly available means of 

compliance methods, but instead used methods developed by Boeing, and specific to the 737 MAX 

aircraft. Id.; see also id. (“I am not aware of any instance where Boeing has made this information 

publicly available.”). Such “means of compliance” information, therefore, is “completely 

proprietary” because it is “entirely intertwined with Boeing’s substantiating technical data, 

drawings, and safety analyses”: it “describes each piece of the proposed design change that is new 

or different from previously certificated models, and explains how Boeing will show that each 

piece complies with applicable FAA regulations and standards.” Cabler Decl. ¶ 27. 

In reply, FlyersRights argues that because Boeing’s “means of compliance” set forth the 

procedures that the FAA will follow to ensure that a manufacturer’s design complies with FAA 

regulations, they constitute “legally binding agency policy,” which is not confidential and must be 

disclosed to prevent the FAA from developing a “body of secret law.” Pls.’ Reply & Opp’n at 17–

18 (internal citations and quotation marks omitted). But, as the FAA points out, “[o]nly applicable 

regulations are binding on the manufacturer.” Def.’s Reply at 8–9 (emphasis added). The FAA 

explains that it “does not follow [the manufacturer’s] means of compliance,” but instead 

determines whether a manufacturer has demonstrated that its design complies with the appliable 

regulations; the manufacturer develops “means of compliance” as a way of “demonstrating their 

compliance to the FAA.” Id. at 9 (citing Second Declaration of Susan Cabler (“2d Cabler Decl.”) 

¶¶ 14–15, ECF No. 28-1). Based on this information, the Court concludes that the FAA has 

demonstrated that Boeing’s “means of compliance” are not “binding agency policy” and that they 

are customarily and actually treated by Boeing as confidential. 

With respect to “safety analyses,” FlyersRights argues that the FAA “publicly released” 

information about its safety analysis of the 737 MAX, including a description of “the functionality 
14 

and failure effects of the angle of attach sensors,” so it is “inconsistent” for the FAA to withhold 

as confidential the contested “safety analyses.” Pl.’s Mot. for S.J. at 21. In response, the FAA 

indicates that the publicly released information to which FlyersRights refers includes “layman’s 

terms” descriptions, but the withheld records “heavily incorporate and describe Boeing’s technical 

data” and include information “intrinsic to Boeing’s design of its proprietary flight control 

software, and reveals elements of how Boeing designed those proprietary features.” Cabler Decl. 

¶ 34. The Court finds that the FAA’s explanation and supporting affidavit show that these “safety 

analyses” incorporate Boeing’s technical and proprietary information, which the company 

“customarily and actually” treats as private. 

As noted above, FlyersRights does not appear to dispute that the remaining categories of 

withheld records involve information “customarily and actually” treated as private by Boeing. 

Based upon its review of Boeing’s and the FAA’s supporting affidavits, the Court is satisfied that 

Boeing “customarily and actually” treats the remaining categories of disputed information as 

“private,” satisfying the first prong of Food Marketing. See, e.g., Cabler Decl. ¶¶ 22–23 

(explaining that “certification plans” involve “proprietary data” and detailed “technical changes” 

and that Boeing treats “certification plans” as confidential commercial information.”); id. ¶ 24 

(nothing that “testing methods, plans, and conditions” are tailored to an applicant’s “specific 

proprietary design”); id. ¶¶ 30–31 (explaining that “flight test plans” are “specific to a particular 

manufacturer’s airplane design” and tailored to each proprietary design, so “the flight test plan is 

highly sensitive commercial information); Polland Decl. ¶ 4 (“The majority of documents 

requested by the Plaintiffs contain trade secrets and other proprietary information that is 

confidential and commercially sensitive. Boeing customarily and actually treats this information 

as private and does not make it available to the public.”); id. ¶¶ 5–6 (explaining that the withheld 
15 

materials “reflect and embody the technical know-how and expertise that Boeing developed over 

decades designing, certifying, and manufacturing aircraft” and that Boeing “limits access to such 

information and does not disclose it publicly, in order to prevent competitors from gaining 

commercial advantage by obtaining detailed technical knowledge about Boeing’s products and 

methods of conducting certification activities”); Allen Decl. ¶ 12 (“Boeing does not make public 

any of the information that it objects to release to Plaintiffs and, in fact Boeing goes to great lengths 

to keep it private.”). 

2. Provided to the Government Under an Assurance of Privacy. 

FlyersRights focuses largely on the second prong of the Food Marketing definition, 

contending that the FAA has failed to demonstrate that Boeing provided the FAA the withheld 

records “under an assurance of privacy.” See Pls.’ Mot. for S.J. at 11–26; Pls.’ Reply & Opp’n at 

6–17. As other courts in this jurisdiction have observed—and as FlyersRights concedes, see Pls.’ 

Mot. for S.J. at 12—the Supreme Court in Food Marketing did not resolve whether the second 

condition is “mandatory,” and therefore it is “an open question . . . whether government assurance 

that information will remain private is necessary for such information to qualify” as confidential 

under Exemption 4. Renewable Fuels Ass’n v. E.P.A., Civil Action No. 18-2031 (JEB), 2021 WL 

602913, at *6 (D.D.C. Feb. 16, 2021) (quoting WP Co. v. Small Bus. Admin., 502 F. Supp. 3d 1, 

16 (D.D.C. 2020)). 

FlyersRights nonetheless contends that courts in this jurisdiction have “effectively applied 

both prongs of the [Food Marketing] test,” Pls.’ Mot. for S.J. at 12, because “in every case they 

have either assumed an assurance of privacy was a requirement, found that this condition has been 

met, or found it highly relevant[,”] Pls.’ Reply & Opp’n at 6–7 (emphasis added). Although other 

courts addressing Exemption 4 disputes since Food Marketing have noted that “whether an agency 
16 

provided ‘an assurance of privacy’ is undoubtedly relevant to determining whether commercial 

information possessed by the agency is confidential,” WP Co., 502 F. Supp. 3d at 16–17 (quoting 

Shapiro v. Dep’t of Justice, Civil Action No. No. 12-313 (BAH), 2020 WL 3615511, at *26 

(D.D.C. July 2, 2020); see also Stotter v. Agency for Int’l Dev., No. 14-2156, 2020 WL 5878033, 

at *5 (D.D.C. Oct. 3, 2020), “none has held that this potential second prong must be met.” 

Renewable Fuels, 2021 WL 602913, at *7 (citing Ctr. for Investigative Reporting v. Customs & 

Border Prot., 436 F. Supp. 3d 90, 113 (D.D.C. 2019); CREW v. Dep’t of Commerce, Civil Action 

No. 18-3022 (CJN), 2020 WL 4732095, at *3 (D.D.C. Aug. 14, 2020)). “Put differently, no court 

has yet held that ‘privately held information lose[s] its confidential character for purposes of 

Exemption 4 if it’s communicated to the government without’ privacy assurances.” Id. (quoting 

Food Marketing, 139 S. Ct. at 2363). 

The Court need not determine whether the second prong of Food Marketing is mandatory 

because it is satisfied that the withheld information was provided by Boeing to the FAA under an 

“assurance of privacy.” The FAA first cites three examples of “express” assurances of privacy. 

First, the FAA points to its FAA Order 8110.4C, Type Certification, which provides that the FAA 

“must not release proprietary information (descriptive, design, and substantiating data received 

from applicants) to any party who does not have written permission from the applicant (or the 

certificate holder).” Cabler Decl. Ex. 2, at Cabler 000212 (emphasis in original). Second, the 

FAA cites its Advisory Circular 20-179, Certification Data Retention Agreements and 

Government Records, which advises certificate applicants that FAA employees “have an 

obligation to protect your proprietary data from unauthorized release[.] Cabler Decl. Ex. 3, at 

Cabler 000302–303. And third, the FAA notes that it has a longstanding agreement with Boeing, 

entered on May 24, 1982, requiring the FAA to obtain Boeing’s written permission to “copy or 
17 

incorporate” Boeing’s information into “FAA prepared airworthiness documents” and to solicit 

Boeing’s response to any request for public disclosure of certain “Airworthiness approval records.” 

Cabler Decl. Ex. 4, at Cabler 000402. 

FlyersRights contends that none of these examples of “express assurances” are sufficient 

because they merely “provide that in handling Boeing proprietary information, the agency will 

comply with the applicable law—including FOIA.” Pls.’ Reply & Opp’n at 9–10. In other words, 

according to FlyersRights, these examples provide “no assurance of privacy for any technical or 

proprietary information not subject to Exemption 4 under otherwise applicable legal standards.” 

Pls.’ Reply & Opp’n at 10 (emphasis added). As the FAA observes, this position is not persuasive 

because FOIA does not mandate public disclosure of “privileged or confidential” “commercial or 

financial information”; it explicitly exempts such information from public release. See 5 U.S.C. § 

552(b)(4). 

In any event, the supporting declarations of Mr. Polland and Ms. Cabler also both detail 

“implied” assurances of privacy based on context and the history of the FAA and Boeing’s 

relationship. See, e.g., Besson v. Dep’t of Commerce, Civ. A. No. 18-2527 (APM), 2020 WL 

4500894, at *5 (D.D.C. Aug. 5, 2020) (finding that information was supplied to agency based on 

implied assurance of confidentiality); CREW, 2020 WL 4732095, at *4 (“The context in which 

[the company] provided [the agency] information—to grow its business in foreign market— 

supports the notion that it did so under an implied assurance of confidentiality.”). For example, 

Mr. Polland of Boeing states: “For decades, Boeing has submitted to the FAA information of the 

sort sought by Plaintiffs with an understanding and expectation that the FAA would treat it as 

private.” Polland Decl. ¶ 23. Mr. Polland testifies that “the FAA has repeatedly made clear, in a 

variety of guidance documents made available to the industry and the public, that it will protect 
18 

from public disclosure confidential information submitted by manufacturers such as Boeing in 

connection with product certification activities to substantiate and demonstrate compliance.” Id. ¶ 

25. Ms. Cabler of the FAA further states: “[T]he FAA has a longstanding history of maintaining 

confidentiality of documents that applicants provide to show compliance with FAA regulations, 

and ultimately obtain a type certificate” and “historically has not released this information to the 

public without the express consent of the applicant.” Cabler Decl. ¶ 62. 

In an effort to contradict these sworn statements, FlyersRights devotes significant portions 

of its briefing and supporting affidavits to discussing public statements made by FAA and Boeing 

officials, indicating that review of the 737 MAX’s design in the wake of the two crashes would be 

“transparent” to the public. See, e.g., Pls.’ Mot. for S.J. at 13–24; Pls.’ Reply & Opp’n at 11–17. 

For example, FlyersRights quotes FAA Administrator Stephen Dickinson’s testimony before a 

Congressional committee, during which he stated, “We believe that transparency, open and honest 

communication, and our willingness to improve our systems and processes are the keys to restoring 

public trust in the FAA and the safety of the 737 MAX.” Pls.’ Mot. for S.J. at 15; The Boeing 737 

MAX: Examining the Federal Aviation Administration’s Oversight of the Aircraft’s Certification: 

Hearing Before the H. Comm. on Transportation and Infrastructure, 116th Cong. 12 (2019) 

(statement of Stephen M. Dickinson, Administrator, FAA). Administrator Dickinson also 

indicated, “The FAA both welcomes and invites scrutiny of our processes and procedures.” Pls.’ 

Mot. for S.J. at 15; The Boeing 737 MAX: Examining the Federal Aviation Administration’s 

Oversight of the Aircraft’s Certification: Hearing Before the H. Comm. on Transportation and 

Infrastructure, 116th Cong. 14 (2019) (statement of Stephen M. Dickinson, Administrator, FAA). 

From these public statements, FlyersRights concludes that the FAA publicly committed to 

disclose to the public the information that it is now withholding, and, in light of these public 
19 

statements, it is “inconsistent” for the FAA and Boeing to claim now that this information was 

provided by Boeing under “an assurance of privacy.” See Pl’s Mot. for S.J. at 13–24; Pls.’ Reply 

& Opp’n at 2, 11–12. FlyersRights also discusses in great detail how disclosure of the information 

contained in the Disputed Information Categories is “important” to allowing outside experts or 

members of the public to assess the safety of the 737 MAX’s design revision (as “welcomed” by 

Administrator Dickinson in his public comments discussed above). Each of the experts who 

submitted a declaration in support of FlyersRights’ motion opines that disclosure of the 

information withheld by the FAA pursuant to Exemption 4 is necessary for any “independent 

expert, aviation journalist, or public interest advocate” to “advise the public” whether there is a 

sufficient basis for the FAA’s decision to return the 737 MAX to service, and that absent such 

information it is “impossible” for each of them to “express any view” or to “inform the public” as 

to the safety of the 737 MAX.5

 

As an initial matter, the FAA correctly observes that FlyersRights does not “identify any 

statements in which these executives and officials committed to releasing any specific document 

or any particular piece of Boeing’s proprietary information.” Def.’s Cross-Mot. & Opp’n at 22; 

Lawrence Decl. ¶ 10. Simply put, a commitment to “transparency” does not equate to a 

commitment to public release of proprietary or confidential information. Def.’s Reply at 7; 

Lawrence Decl. ¶ 13. Moreover, although the Court appreciates FlyersRights’ desire to 

independently analyze the safety of the 737 MAX, the “importance” or “necessity” of the withheld

materials to any such external scrutiny has no bearing on whether such material must be disclosed 

under FOIA. See Def.’s Reply at 8. 

The Court concludes that the FAA has carried its burden to demonstrate that the disputed 

records were provided to the agency under express and implied assurances of privacy, which 

satisfies the second prong of the Supreme Court’s Food Marketing test. Accordingly, the FAA 

has demonstrated that the material it withheld from production satisfies Exemption 4’s definition 

of “confidential” information. 

C. The FAA Has Demonstrated that it Released All Reasonably Segregable Information. 

Although the Court concludes that the FAA properly withheld the disputed records 

pursuant to Exemption 4, it must also “make specific findings of segregability regarding the 

documents to be withheld.” Stolt-Nielsen Transp. Grp., 534 F.3d at 734 (internal quotation marks 

omitted) (quoting Sussman v. U.S. Marshals Serv., 494 F.3d 1106, 1116 (D.C. Cir. 2007)); see 

also Morley v. CIA, 508 F.3d 1108, 1123 (D.C. Cir. 2007) (explaining that a district court has “an 

affirmative duty to consider the segregability issue sua sponte” (internal quotation marks omitted) 

(quoting Trans-Pac. Policing Agreement v. U.S. Customs Serv., 177 F. 3d 1022, 1028 (D.C. Cir. 

1999)). “Agencies are entitled to a presumption that they complied with the obligation to disclose 

reasonably segregable material.” Sussman, 494 F.3d at 1117. Affidavits attesting to the agency’s 

“line-by-line review of each document withheld in full” and the agency’s determination “that no 

documents contained releasable information which could be reasonably segregated from the 

nonreleasable portions,” in conjunction with a Vaughn index describing the withheld record, 

suffice. Id. (internal quotation marks omitted); see also Loving v. Dep’t of Defense, 550 F.3d 32, 

41 (D.C. Cir. 2008) (stating that “the description of the document set forth in the Vaughn index 
21 

and the agency's declaration that it released all segregable material” are “sufficient for [the 

segregability] determination”). 

Granting the FAA its due presumption of regularity, the Court finds that the FAA has 

discharged its burden concerning segregability with respect to these three categories of records. 

The sworn declaration of Ms. Cabler, submitted in support of the FAA’s Cross-Motion for 

Summary Judgment, establishes that each contested document was reviewed “line by line” and 

that “[w]here possible, the FAA segregated and release information not covered under any FOIA 

exemption.” Cabler Decl. ¶ 66. 

IV. CONCLUSION 

Because the Court finds that the FAA properly withheld the records at issue in this case 

pursuant to FOIA Exemption 4, the Court GRANTS the FAA’s motion for summary judgment 

and DENIES FlyersRights’ motion for summary judgment. An appropriate Order accompanies 

this Memorandum Opinion.
