14 CFR Part 39 

[Docket No. FAA–2023–1805; Project 

Identifier AD–2023–00019–T] 

RIN 2120–AA64 

Airworthiness Directives; Gulfstream 

Aerospace Corporation Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to 

supersede Airworthiness Directive (AD) 

2020–23–04, which applies to certain 

Gulfstream Aerospace Corporation 

Model GVII–G500 and GVII–G600 

airplanes. AD 2020–23–04 requires 

revising the existing airplane flight 

manual (AFM) and airplane 

maintenance manual (AMM) to include 

information pertaining to the fuel boost 

pump. Since the FAA issued AD 2020– 

23–04, an inspection for a missing or 

misplaced impeller shaft key of suspect 

fuel boost pumps has been developed 

that would terminate the actions of AD 

2020–23–04. This proposed AD would 

retain the requirements of AD 2020–23– 

04 and require inspecting affected fuel 

boost pumps for proper installation of 

the impeller shaft key, marking affected 

fuel boost pumps that pass that 

inspection, and replacing fuel boost 

pumps that fail. This proposed AD 

would also limit installation of affected 

fuel boost pumps. The FAA is proposing 

this AD to address the unsafe condition 

on these products. 

DATES: The FAA must receive comments 

on this proposed AD by October 20, 

2023. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following

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 Jared Meyer, Aviation 

Safety Engineer, FAA, 1701 Columbia 

Avenue, College Park, GA 30337; phone: 

404–474–5534; email: 9-ASO-ATLACOADs@faa.gov. Any commentary that the 

FAA receives that is not specifically

public docket for this rulemaking. 

Background 

The FAA issued AD 2020–23–04, 

Amendment 39–21320 (85 FR 71232, 

November 9, 2020) (AD 2020–23–04), 

for certain Gulfstream Aerospace 

Corporation Model GVII–G500 and 

GVII–G600 airplanes. AD 2020–23–04 

was prompted by a report of 

misassembled impellers on the shaft of 

the fuel boost pump during production. 

AD 2020–23–04 requires revising the 

existing AFM and AMM to include 

information pertaining to the fuel boost 

pump. The agency issued AD 2020–23– 

04 to prevent the ignition of flammable 

vapors in the fuel tank as a result of 

frictional heating or sparks caused by a 

dislodged impeller shaft key inside the 

fuel boost pump, which, if the pump 

were to run dry, could result in a fuel 

tank fire or fuel tank explosion. 

Actions Since AD 2020–23–04 Was 

Issued 

The preamble to AD 2020–23–04 

specifies that the FAA considers the 

requirements ‘‘interim action’’ and that 

the manufacturer is developing a 

modification that will address the 

unsafe condition. That AD explains that 

the FAA might consider further 

rulemaking if a modification is 

developed, approved, and available. The 

manufacturer now has developed 

inspection instructions for fuel boost 

pumps to determine correct installation 

of the impeller shaft key, including 

replacement or re-identification, as 

applicable, that will terminate the 

requirement to update the AFM and 

AMM, and the FAA has determined that 

further rulemaking is indeed necessary; 

this proposed AD follows from that 

determination.

Federal Register / Vol. 88, No. 170 / Tuesday, September 5, 2023 / Proposed Rules 60607 

FAA’s Determination 

The FAA is issuing this NPRM after 

determining that the unsafe condition 

described previously is likely to exist or 

develop on other products of the same 

type design. 

Related Service Information Under 1 

CFR Part 51 

The FAA reviewed Gulfstream GVII– 

G500 Customer Bulletin No. 069 and 

Gulfstream GVII–G600 Customer 

Bulletin No. 037, both Revision A, both 

dated February 2, 2023, which describe 

procedures for inspecting affected fuel 

boost pumps for proper installation of 

the impeller shaft key, marking affected 

fuel boost pumps that pass that 

inspection, and replacing fuel boost 

pumps that fail. These documents are 

distinct since they apply to different 

airplane models. 

This proposed AD would also require 

the following Gulfstream service 

information, which the Director of the 

Federal Register approved for 

incorporation on November 24, 2020 (85 

FR 71232).

Proposed AD Requirements in This 

NPRM 

This proposed AD would retain all 

requirements of AD 2020–23–04. This 

proposed AD would also require 

accomplishing the actions identified as 

‘‘RC’’ (required for compliance) in the 

Accomplishment Instructions of 

Gulfstream GVII–G500 Customer 

Bulletin No. 069 and Gulfstream GVII– 

G600 Customer Bulletin No. 037, both 

Revision A, both dated February 2, 

2023, already described, except as 

discussed under ‘‘Differences Between 

the Service Information and this 

Proposed AD.’’ This proposed AD 

would also limit the installation of 

affected parts. 

Difference Between Service Information 

and This Proposed AD 

For this AD, step III.D. of Gulfstream 

GVII–G500 Customer Bulletin No. 069, 

Revision A, dated February 2, 2023, and 

Gulfstream GVII–G600 Customer 

Bulletin No. 037, Revision A, dated 

February 2, 2023, as applicable, is also 

RC. 

Costs of Compliance 

The FAA estimates that this AD, if 

adopted as proposed, would affect 89 

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 

Incorporate information into AMM and AFM (retained actions from AD 2020–23–04).2 work-hours × $85 per hour = $170 ................. $0 $170 $15,130 

Impeller shaft key inspection (new proposed action).36 work-hours × $85 per hour = $3,060 ............ 0 3,060 272,340 

The FAA estimates the following 

costs to do any necessary part marking 

and fuel boost pump replacements that 

would be required based on the results 

of the proposed inspection for proper 

installation. The FAA has no way of 

determining the number of aircraft that 

might need these actions: 

ON-CONDITION COSTS

Action Labor cost Parts cost Cost per 

product 

Part marking ...................................................................... 0.5 work-hour × $85 per hour = $42.50 .......................... $10 $52.50 

Fuel pump replacement (per fuel boost pump) ................ 10 work-hours × $85 per hour = $850 ............................. 106,706 107,556 

The FAA has included all known 

costs in its cost estimate. According to 

the manufacturer, however, some or all 

of the costs of this proposed AD may be 

covered under warranty, thereby 

reducing the cost impact on affected 

operators. 

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. 


ddrumheller on DSK120RN23PROD with PROPOSALS1
60608 Federal Register / Vol. 88, No. 170 / Tuesday, September 5, 2023 / Proposed Rules 

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 has 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 that the proposed regulation: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866, 

(2) Would not affect intrastate 

aviation in Alaska, and 

(3) Would 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
