Federal Register / Vol. 86, No. 153 / Thursday, August 12, 2021 / Proposed Rules the FAA proposes to amend 14 CFR part 39 as follows:

i No Reporting Requirement
PART 39AIRWORTHINESS
DIRECTIVES

Although the service information referenced in EASA AD 20210112 specifies to submit certain information to the manufacturer, this AD does not include that requirement.

1. The authority citation for part 39
continues to read as follows:

Authority: 49 U.S.C. 106g, 40113, 44701.
39.13

Amended
2. The FAA amends 39.13 by adding the following new airworthiness directive AD:

Airbus SAS: Docket No. FAA20210657;
Project Identifier MCAI202100478T.
a Comments Due Date The FAA must receive comments on this airworthiness directive AD by September 27, 2021.
b Affected ADs None.
c Applicability This AD applies to Airbus SAS Model A350941 and 1041 airplanes, certificated in any category, as identified in European Union Aviation Safety Agency EASA AD
20210112, dated April 22, 2021 EASA AD
20210112.
d Subject Air Transport Association ATA of America Code 57, Wings.
e Reason This AD was prompted by a report indicating that during maintenance, a fuse pin retaining the main landing gear support structure MLGSS was found incorrectly engaged in the trunnion block and improperly secured with the associated retaining pin, due to incorrect installation during assembly. The FAA is issuing this AD
to address incorrect fuse pin installations, which could lead to premature failure of the retaining pin and subsequent fuse pin migration and disconnection, and could ultimately lead to main landing gear collapse and possible damage to the airplane.
f Compliance Comply with this AD within the compliance times specified, unless already done.
