Airworthiness Directive 2025-24014
one-timeAirworthiness Directives; Aerospace & Defense Oxygen Systems SaS (Part of Safran Aerosystems) (Formerly Known as Air Liquide)
What this AD requires
The FAA is superseding Airworthiness Directive (AD) 2025-25- 02, which applied to all aircraft equipped with certain Aerospace & Defense Oxygen Systems SaS portable breathing equipment (PBE). AD 2025- 25-02 required incorporating revised procedures for donning the PBE. Since the FAA issued AD 2025-25-02, the agency determined the unsafe condition may be addressed by incorporating the updated procedures into documentation that is not identified in AD 2025-25-02 and that certain requirements in AD 2025-25-02 must be revised. This AD requires incorporating updated procedures for donning the PBE. The FAA is issuing this AD to address the unsafe condition on these products.
Which aircraft AD 2025-24014 applies to
Whether AD 2025-24014 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.
