Airworthiness Directive 2025-11-12
one-timeAirworthiness Directives; Airbus SAS Airplanes
What this AD requires
The FAA is superseding Airworthiness Directive (AD) 2020-03- 14, which applied to all Airbus SAS Model A350-941 and -1041 airplanes. AD 2020-03-14 required an inspection of affected crew oxygen cylinder assemblies for any discrepancy and replacement of discrepant crew oxygen cylinder assemblies with serviceable parts, and allowed installation of affected parts under certain conditions. Since the FAA issued AD 2020-03-14, the supplier introduced an improved crew oxygen cylinder assembly, that will ensure the correct function of the system. This AD continues to require the actions in AD 2020-03-14, requires replacement of all affected parts with redesigned parts, and also prohibits the installation of affected parts. The FAA is issuing this AD to address the unsafe condition on these products.
Which aircraft AD 2025-11-12 applies to
Whether AD 2025-11-12 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
