discrete wire failure, the landing gear 

extension and retraction system 

(LGERS) may not be able to complete 

landing gear retraction when 

commanded by moving the landing gear 

lever to the UP position. This AD 

requires revising the operator’s existing 

FAA-approved minimum equipment list 

(MEL) for the LGERS, as specified in a 

European Union Aviation Safety Agency 

(EASA) AD, which is incorporated by 

reference. The FAA is issuing this AD 

to address the unsafe condition on these 

products. 

DATES: This AD is effective April 11, 

2022. 

The Director of the Federal Register

SUPPLEMENTARY INFORMATION: 

Background 

EASA, which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA AD 2021–0161, 

dated July 6, 2021 (EASA AD 2021– 

0161) (also referred to as the MCAI), to 

correct an unsafe condition for all 

Airbus SAS Model A350–941 and –1041 

airplanes. 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to all Airbus SAS Model A350– 

941 and –1041 airplanes. The NPRM 

was published in the Federal Register 

on December 17, 2021 (86 FR 71587). 

The NPRM was prompted by a report 

that in the event of a specific discrete 

wire failure, the LGERS may not be able 

to complete landing gear retraction 

when commanded by moving the 

landing gear lever to the UP position. 

The NPRM proposed to require revising 

the operator’s existing FAA-approved 

MEL for the LGERS, as specified in 

EASA AD 2021–0161. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received a comment from 

The Air Line Pilots Association, 

International (ALPA), who supported 

the NPRM without change. 

Conclusion 

The FAA reviewed the relevant data, 

considered the comment received, and 

determined that air safety requires 

adopting this AD as proposed. Except 

for minor editorial changes, this AD is 

adopted as proposed in the NPRM. 

None of the changes will increase the 

economic burden on any operator. 

Accordingly, the FAA is issuing this AD 

to address the unsafe condition on these 

products.

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. 

Costs of Compliance 

The FAA estimates that this AD 

affects 19 airplanes of U.S. registry. The 

FAA estimates the following costs to 

comply with this AD: 

ESTIMATED COSTS FOR REQUIRED ACTIONS

product 

Cost on U.S. 

operators 

2 work-hours × $85 per hour = $170 .......................................................................................... $0 $170 $3,230 

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 

This AD will not have federalism 

implications under Executive Order 

13132. This AD will 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 this AD: 

(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 Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA amends 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: 

2022–05–07 Airbus SAS: Amendment 39– 

21958; Docket No. FAA–2021–1059; 

Project Identifier MCAI–2021–00797–T. 

(a) Effective Date 

This airworthiness directive (AD) is 

effective April 11, 2022. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to all Airbus SAS Model 

A350–941 and –1041 airplanes, certificated 

in any category. 

(d) Subject 

Air Transport Association (ATA) of 

America Code 32, Landing gear. 

(e) Unsafe Condition 

This AD was prompted by a report that in 

the event of a specific discrete wire failure, 

the landing gear extension and retraction 

system (LGERS) may not be able to complete 

landing gear retraction when commanded by 

moving the landing gear lever to the UP 

position. The FAA is issuing this AD to 

address this condition, which, if one engine 

is inoperative at takeoff, could lead to a 

reduction of the flight path clearance and 

possibly result in damage to the airplane and 

injury to occupants. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Requirements 

Except as specified in paragraph (h) of this 

AD: Comply with all required actions and 

compliance times specified in, and in 

accordance with, EASA AD 2021–0161, 

dated July 6, 2021 (EASA AD 2021–0161). 

(h) Exceptions to EASA AD 2021–0161 

(1) Where EASA AD 2021–0161 refers to its 

effective date, this AD requires using the 

effective date of this AD. 

(2) Whereas paragraph (1) of EASA AD 

2021–0161 specifies to ‘‘inform all flight 

crews, and, thereafter, operate the aeroplane 

accordingly,’’ this AD does not require those 

actions as those actions are already required 

by existing FAA operating regulations. 

(3) The ‘‘Remarks’’ section of EASA AD 

2021–0161 does not apply to this AD. 

(i) Additional AD Provisions 

The following provisions also apply to this 

AD:

SUPPLEMENTARY INFORMATION: 

Background 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to certain GE CF34–10E2A1, 

CF34–10E5, CF34–10E5A1, CF34–10E6, 

CF34–10E6A1, CF34–10E7, and CF34– 

10E7–B (CF34–10E) model turbofan 

engines. The NPRM published in the 

Federal Register on August 24, 2021 (86 

FR 47264). The NPRM was prompted by 

a manufacturer investigation that 

revealed Teflon material in the strainer 

assembly screen after several reports of 

IFSDs and UERs on airplanes operating 

with GE CF34–10E5, CF34–10E5A1, 

CF34–10E6, and CF34–10E7 model 

turbofan engines. After investigation, 

the manufacturer determined that the 

failures were the result of Teflon oil 

seals disbonding from the aluminum 

housing when used with either high 

thermal stability (HTS) or high 

performance capability (HPC) oils. The 

stationary oil seal deterioration resulted 

from the failure of the bonding 

adhesive, known as EA9658, which 

does not have the high temperature 

capabilities as designed and is 

negatively impacted by the use of HTS 

or HPC oils. This deterioration results in 

Teflon particles collecting in the 

strainer assembly. The manufacturer 

determined that CF34–10E2A1, CF34– 

10E6A1, and CF34–10E7–B model 

turbofan engines are subject to the same 

unsafe condition. In the NPRM, the FAA 

proposed to require initial and 

repetitive visual inspections of the 

strainer assembly screen. As a 

terminating action to the initial and 

repetitive visual inspections, the FAA 

proposed to require the replacement of 

the stationary oil seal, part number (P/ 

N) B1316–00453 or P/N B1316–01274, 

installed at the No. 1 forward bearing. 

The FAA is issuing this AD to address 

the unsafe condition on these products. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received comments from 

four commenters. The commenters were 

the Air Line Pilots Association, 

International (ALPA), GE, Helvetic 

Airways AG (Helvetic Airways), and 

JetBlue Airways (JetBlue). The following 

presents the comments received on the 

NPRM and the FAA’s response to each 

comment. 

Request To Change the Applicability 

GE, Helvetic Airways, and JetBlue 

requested that the FAA change 

paragraph (c), Applicability, of this AD 

to align with GE CF34–10E Service 

Bulletin (SB) 72–0365 R04, dated April 

27, 2021 (GE CF34–10E SB 72–0365 

R04). GE specifically requested that the 

FAA include language that specifies the 

timeframe (after September 2014) to 


khammond on DSKJM1Z7X2PROD with RULES
