AGENCY: Federal Aviation

ACTION: Proposed rule; withdrawal. 

SUMMARY: The FAA is withdrawing a 

notice of proposed rulemaking (NPRM) 

that proposed to adopt a new 

airworthiness directive (AD) for certain 

Gulfstream Aerospace Corporation 

(Gulfstream) Model GVII–G500 

airplanes. The NPRM was prompted by 

a report of a fuel quantity disparity 

between the overhead panel touch 

screens and the touch screen 

controllers. The NPRM proposed to 

require incorporating operating 

limitations into the airplane flight 

manual (AFM) until the fuel quantity 

management system (FQMS) software is 

updated. Since issuance of the NPRM, 

the FAA has determined that there is 

not an unsafe condition because all 

affected airplanes have updated 

software. Accordingly, the NPRM is 

withdrawn. 

DATES: As of July 23, 2021, the proposed 

rule, which published in the Federal 

Register on July 28, 2020 (85 FR 45345), 

is withdrawn.

SUPPLEMENTARY INFORMATION: 

Background 

The FAA issued an NPRM that 

proposed to amend 14 CFR part 39 by 

adding an AD that would apply to 

certain serial-numbered Gulfstream 

Model GVII–G500 airplanes. The NPRM 

published in the Federal Register on 

July 28, 2020 (85 FR 45345). The NPRM 

was prompted by a report of the affected 

airplanes exhibiting a disparity between 

the fuel quantities displayed on the 

overhead panel touch screens and the 

fuel quantities displayed on the touch 

screen controllers. An investigation 

revealed two known failure conditions 

that the Model GVII–G500 FQMS does 

not properly detect and report to the 

crew. These failure conditions are fuel 

quantity probe drift and an FQMS overcurrent condition, which could result in 

erroneous and misleading fuel quantity 

indications and could also result in 

erroneous and misleading fuel 

imbalance indications. These conditions 

could cause a false annunciation of a 

fuel imbalance, a failure to annunciate 

an actual fuel imbalance, and a 

condition where the actual fuel quantity 

is less than or greater than the indicated 

fuel quantity. The FQMS software logic 

does not properly detect or compensate 

for these failure conditions. This 

condition, if not corrected, could result 

in fuel starvation during flight, 

performance impacts of the airplane 

having more fuel than indicated, and a 

roll moment due to a fuel imbalance. 

The NPRM proposed to require 

incorporating operating limitations into 

the AFM until the fuel quantity signal 

conditioner FQMS software is updated 

to version 10003–42130–01–19.03. 

Actions Since the NPRM Was Issued 

After issuance of the NPRM, the FAA 

determined that all Gulfstream Model 

GVII–G500 airplanes are in compliance 

with the proposed software update, and 

the unsafe condition has been removed 

from the fleet. In addition, since 

Gulfstream controls the software, it is 

unlikely the unsafe condition will be reintroduced. 

Based on the above information, the 

FAA has determined that AD action is 

not warranted and the proposal should 

be withdrawn.

Comments 

The FAA received comments from 

Gulfstream and an individual 

commenter. 

Requests 

Gulfstream requested that the FAA 

change the credit for previous actions. 

The individual commenter requested 

the FAA clarify the correct revision of 

the service information to reference. 

The FAA acknowledges these 

comments. However, because the NPRM 

is being withdrawn, the commenters’ 

requests are no longer necessary. 

Withdrawal of the NPRM constitutes 

only such action and does not preclude 

the FAA from further rulemaking on 

this issue, nor does it commit the FAA 

to any course of action in the future. 

Regulatory Findings 

Since this action only withdraws an 

NPRM, it is neither a proposed AD nor 

a final rule. This action, therefore, is not 

covered under Executive Order 12866 or 

the Regulatory Flexibility Act.

The Withdrawal 

■ Accordingly, the notice of proposed 

rulemaking, which published in the 

Federal Register on July 28, 2020 (85 FR

Airworthiness Directives; Leonardo 

S.p.a. Helicopters 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to adopt a 

new airworthiness directive (AD) for 

certain Leonardo S.p.a Model AW169 

helicopters. This proposed AD was 

prompted by reports of in-flight pilot 

collective stick oscillation. This 

proposed AD would require a one-time 

measurement of the friction of the pilot 

collective stick assembly to verify that it 

is within the allowable range and, 

depending on findings, making an 

adjustment to restore the acceptable 

level of friction, as specified in a 

European Aviation Safety Agency (now 

European Union Aviation Safety 

Agency) (EASA) AD, which is proposed 

for incorporation by reference (IBR). 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 September 7, 

2021. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods: 

• Federal eRulemaking Portal: Go to 

https://www.regulations.gov. Follow the 

instructions for submitting comments. 

• Fax: (202) 493–2251.
