Federal Register / Vol. 86, No. 87 / Friday, May 7, 2021 / Proposed Rules 39.13

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

Airbus SAS: Docket No. FAA20210343;
Project Identifier MCAI202100013T.
a Comments Due Date The FAA must receive comments on this airworthiness directive AD by June 21, 2021.
b Affected ADs None.
c Applicability This AD applies to all Airbus SAS Model A350941 and 1041 airplanes, certificated in any category.
d Subject Air Transport Association ATA of America Code 52, Doors.
e Reason This AD was prompted by a report that during an inspection of the flight deck escape hatches it was found that they were difficult to open from the inside, and several hatches were found impossible to open from the outside. Subsequent investigation revealed corrosion on the flight deck escape hatch mechanism due to condensation penetrating inside the mechanism. The FAA is issuing this AD to address possible inaccessibility of the flight deck escape hatch, which could impede flightcrew evacuation during an emergency.

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, European Union Aviation Safety Agency EASA AD 20210004, dated January 6, 2021 EASA AD 20210004.

The FAA is proposing this AD to address the unsafe condition on these products.

SUMMARY:

The FAA must receive comments on this proposed AD by June 21, 2021.
