SUPPLEMENTARY INFORMATION: 

Comments Invited 

The FAA invites you to send any 

written relevant data, views, or 

arguments about this proposed AD. 

Send your comments to an address 

listed under the ADDRESSES section. 

Include ‘‘Docket No. FAA–2020–0831; 

Project Identifier 2019–CE–031–AD’’ at 

the beginning of your comments. The 

most helpful comments reference a 

specific portion of the proposal, explain 

the reason for any recommended 

change, and include supporting data. 

The FAA will consider all comments 

received by the closing date and may 

amend this proposal because of those 

comments. 

Except for Confidential Business 

Information (CBI) as described in the 

following paragraph, and other 

information as described in 14 CFR 

11.35, the FAA will post all comments 

received, without change, to https://

www.regulations.gov, including any 

personal information you provide. The 

agency will also post a report 

summarizing each substantive verbal 

contact received about this NPRM. 

Confidential Business Information 

CBI is commercial or financial 

information that is both customarily and 

actually treated as private by its owner. 

Under the Freedom of Information Act 

(FOIA) (5 U.S.C. 552), CBI is exempt 

from public disclosure. If your 

comments responsive to this NPRM 

contain commercial or financial 

information that is customarily treated 

as private, that you actually treat as 

private, and that is relevant or 

responsive to this NPRM, it is important 

that you clearly designate the submitted 

comments as CBI. Please mark each 

page of your submission containing CBI 

as ‘‘PROPIN.’’ The FAA will treat such 

marked submissions as confidential 

under the FOIA, and they will not be 

placed in the public docket of this 

NPRM. Submissions containing CBI 

should be sent to Ronald ‘‘Ron’’ 

Wissing, Aviation Safety Engineer, 

Atlanta ACO Branch, FAA, 1701 

Columbia Avenue, College Park, Georgia 

30337. Any commentary that the FAA 

receives which is not specifically 

designated as CBI will be placed in the 

public docket for this rulemaking. 

Background 

The FAA was advised of a failed floor 

beam support link at right butt line 

(RBL) 6 on a Gulfstream Model GV 

airplane. The failed support link 

resulted from seizure of the retaining 

sleeve and bushing at the lower 

attachment point due to undetected 

corrosion. The floor beam support links 

at RBL 6, fuselage stations (FS) 499, 531, 

and 569.5 have a two-piece installation 

with straight bushings rather than 

spherical bearings in the inboard link 

lower end. Design of the support links 

allows floor beam movement when the 

cabin is pressurized. Seizure of the 

lower bushing will not allow the link 

assembly to move as designed, resulting 

in bending stress and potential failure of 

the link, which may compromise the 

integrity of the pressure vessel floor. 

Gulfstream determined that the 

procedures for the existing Aircraft 

Maintenance Manual (AMM) inspection 

does not reliably detect corrosion in the 

floor beam support link lower bushings. 

Accordingly, Gulfstream has revised the 

airworthiness limitation requirements to 

the AMM by adding a detailed 

inspection with an initial and repetitive 

inspections at intervals of 96 months 

and including references for removal 

and installation instructions for RBL 6 

Floor Beam Support Links. 

This condition, if not addressed, 

could result in link failure, which can 

compromise the integrity of the pressure 

vessel floor and lead to loss of 

pressurization to the airplane. 

Related Service Information Under 1 

CFR Part 51 

The FAA reviewed Gulfstream GV 

Customer Bulletin Number 231, 

Revision A, dated July 30, 2019 

(Gulfstream CB 231A). The service 

information contains procedures for the 

inspection of the RBL 6, FS 499, 531, 

and 569.5, and the bushing in the lower 

end of the link and all attachments for 

corrosion. 

The FAA reviewed Gulfstream GV 

AMM, Section 05–10–10, Revision 51, 

dated February 28, 2020. The service 

information identifies tasks for a 

recurring detailed inspection of the floor 

beam and wing links FS 465 through FS 

576. 

This service information is reasonably 

available because the interested parties 

have access to it through their normal 

course of business or by the means 

identified in the ADDRESSES section. 

FAA’s Determination 

The FAA is issuing this NPRM after 

determining that the unsafe condition 

described previously is likely to exist or 

develop in other products of the same 

type design. 

Proposed AD Requirements 

This proposed AD would require a 

one-time inspection of the RBL 6 floor 

beam inboard support links and 

bushings for corrosion along with any 

repairs necessary. This proposed AD 

would require a recurring inspection of 


jbell on DSKJLSW7X2PROD with PROPOSALS
Federal Register / Vol. 85, No. 238 / Thursday, December 10, 2020 / Proposed Rules 79445 

the floor beam support links. This 

proposed AD also recommends sending 

the inspection results to Gulfstream. 

Differences Between This Proposed AD 

and the Service Information 

Gulfstream CB 231A requires 

reporting the results of the inspection to 

Gulfstream and this proposed AD would 

not. 

Costs of Compliance 

The FAA estimates that this proposed 

AD would affect 148 airplanes of U.S. 

registry. 

The FAA estimates the following 

costs to comply with this proposed AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Inspection per the Customer 

Bulletin, all 3 locations.

120 work-hours × $85 per hour = $10,200 ............................ Not applicable $10,200 $1,509,600 

Revise the AMM ..................... 1 work-hour × $85 per hour = $85 ......................................... Not applicable 85 12,580 

The FAA estimates the following 

costs to do any necessary replacements 

that would be required based on the 

results of the proposed inspection. The 

FAA has no way of determining the 

number of airplanes that might need 

these replacements: 

ON-CONDITION COSTS

Action Labor cost Parts cost Cost per 

product 

Replacement of all 3 links ............... 40 work-hours × $85 per hour = $3,400 ................................................... $316 $3,716 

According to the manufacturer, some 

of the costs of this proposed AD may be 

covered under warranty, thereby 

reducing the cost impact on affected 

individuals. The FAA does not control 

warranty coverage for affected operators. 

As a result, the FAA has included all 

costs in this cost estimate. 

Authority for This Rulemaking 

Title 49 of the United States Code 

specifies the FAA’s authority to issue 

rules on aviation safety. Subtitle I, 

section 106, describes the authority of 

the FAA Administrator. Subtitle VII: 

Aviation Programs, describes in more 

detail the scope of the Agency’s 

authority. 

The FAA is issuing this rulemaking 

under the authority described in 

Subtitle VII, Part A, Subpart III, Section 

44701: General requirements. Under 

that section, Congress charges the FAA 

with promoting safe flight of civil 

aircraft in air commerce by prescribing 

regulations for practices, methods, and 

procedures the Administrator finds 

necessary for safety in air commerce. 

This regulation is within the scope of 

that authority because it addresses an 

unsafe condition that is likely to exist or 

develop on products identified in this 

rulemaking action. 

Regulatory Findings 

The FAA determined that this 

proposed AD would not have federalism 

implications under Executive Order 

13132. This proposed AD would not 

have a substantial direct effect on the 

States, on the relationship between the 

national government and the States, or 

on the distribution of power and 

responsibilities among the various 

levels of government. 

For the reasons discussed above, I 

certify this proposed regulation: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866, 

(2) Will not affect intrastate aviation 

in Alaska, and 

(3) Will not have a significant 

economic impact, positive or negative, 

on a substantial number of small entities 

under the criteria of the Regulatory 

Flexibility Act. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Incorporation by reference, 

Safety. 

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 14 CFR part 

39 as follows: 

PART 39—AIRWORTHINESS 

DIRECTIVES 

■ 1. The authority citation for part 39 

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 [Amended] 

■ 2. The FAA amends § 39.13 by adding 

the following new airworthiness 

directive: 

Gulfstream Aerospace Corporation: Docket 

No. FAA–2020–0831; Project Identifier 

2019–CE–031–AD. 

(a) Comments Due Date 

The FAA must receive comments on this 

airworthiness directive (AD) by January 25, 

2021. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to Gulfstream Aerospace 

Corporation Model GV airplanes, all serial 

numbers, certificated in any category. 

(d) Subject 

Air Transport Association of America 

(ATA) Code 53: Fuselage Structure. 

(e) Reason 

This AD was prompted by a report that 

current inspection procedures of floor beam 

support links, which can fail due to 

corrosion, are inadequate. The FAA is issuing 

this AD to detect and correct corrosion on a 

floor beam support link lower bushing. This 

condition, if not addressed, could result in 

link failure, which can compromise the 

integrity of the pressure vessel floor and lead 

to loss of pressurization of the airplane. 

(f) Actions and Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Action 

(1) Within 24 months after the effective 

date of this AD, inspect the right butt line 6 

floor beam inboard support links at fuselage 

stations (FS) 499, 531, and 569.5 for 

corrosion by following the Accomplishment 

Instructions, steps A through M, of

this paragraph, the Manager’s approval letter 

must specifically refer to this AD. 

(2) Within 24 months after the effective 

date of this AD, revise the airworthiness 

limitations section of your maintenance 

manual or inspection program to incorporate 

the airworthiness limitations specified in 

Table 13: Fuselage Inspection Table, of 

Gulfstream GV Aircraft Maintenance Manual, 

Section 05–10–10, Revision 51, dated 

February 28, 2020. Thereafter, except as 

provided in paragraph (h) of this AD, no 

alternative inspection intervals may be 

approved for the fuselage floor beam and 

wing link FS 465–FS 576. 

(h) Alternative Methods of Compliance 

(AMOCs) 

(1) The Manager, Atlanta ACO Branch, 

FAA, has the authority to approve AMOCs 

for this AD, if requested using the procedures 

found in 14 CFR 39.19. In accordance with 

14 CFR 39.19, send your request to your 

principal inspector or local Flight Standards 

District Office, as appropriate. If sending 

information directly to the manager of the 

certification office, send it to the attention of 

the person identified in paragraph (i)(1) of 

this AD. 

(2) Before using any approved AMOC, 

notify your appropriate principal inspector, 

or lacking a principal inspector, the manager 

of the local flight standards district office/ 

certificate holding district office. 

(3) Except as required by paragraph (g) of 

this AD: For service information that 

contains steps that are labeled as Required 

for Compliance (RC), the following 

provisions apply. 

(i) The steps labeled as RC, including 

substeps under an RC step and any figures 

identified in an RC step, must be done to 

comply with the AD. An AMOC is required 

for any deviations to RC steps, including 

substeps and identified figures. 

(ii) Steps not labeled as RC may be 

deviated from using accepted methods in 

accordance with the operator’s maintenance 

or inspection program without obtaining 

approval of an AMOC, provided the RC steps, 

including substeps and identified figures, can 

still be done as specified, and the airplane 

can be put back in an airworthy condition.

SUPPLEMENTARY INFORMATION: 

Authority for This Rulemaking 

The FAA’s authority to issue rules 

regarding aviation safety is found in 

Title 49 of the United States Code. 

Subtitle I, Section 106 describes the 

authority of the FAA Administrator. 

Subtitle VII, Aviation Programs, 

describes in more detail the scope of the 

agency’s authority. This rulemaking is 

promulgated under the authority 

described in Subtitle VII, Part A, 

Subpart I, Section 40103. Under that 

section, the FAA is charged with 

prescribing regulations to assign the use 

of the airspace necessary to ensure the 

safety of aircraft and the efficient use of 

airspace. This regulation is within the 

scope of that authority as it would 

modify the route structure as necessary 

to preserve the safe and efficient flow of 

air traffic within the National Airspace 

System (NAS).
