Airbus SAS Model A350941 and 1041
airplanes. 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. This AD requires replacing all affected flight deck escape hatches with serviceable hatches, 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 September 9, 2021.

EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 20210004, dated January 6, 2021 EASA AD 2021
0004 also referred to as the Mandatory Continuing Airworthiness Information, or the MCAI, to correct an unsafe condition for all Airbus SAS Model A350941 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
published in the Federal Register on May 7, 2021 86 FR 24549. The NPRM
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 NPRM proposed to require replacing all affected flight deck escape hatches with serviceable hatches, as specified in EASA AD 20210004.
The FAA is issuing this AD to address possible inaccessibility of the flight deck escape hatch, which could impede flightcrew evacuation during an emergency. See the MCAI for additional background information.
Comments The FAA gave the public the opportunity to participate in developing this final rule. The Air Line Pilots Association, International ALPA
indicated its support for the NPRM.
The FAA reviewed the relevant data, considered the comment received, and determined that air safety and the public interest require adopting this final rule as proposed, except for minor editorial changes. The FAA has determined that these minor changes:
Are consistent with the intent that was proposed in the NPRM for addressing the unsafe condition; and Do not add any additional burden upon the public than was already proposed in the NPRM.
Related Service Information Under 1
CFR Part 51
EASA AD 20210004 describes procedures for replacing all affected flight deck escape hatches with serviceable flight deck escape hatches.
