Airworthiness Directive coverage
FAA / EASA public regulatory data
- EASAAD 2025-0297effective Feb 17, 2026Prohibition
No summary available - see the EASA publication.
- FAAAD 2025-26-06effective Jan 14, 2026Mixed actions
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.
- FAAAD 2025-25-02effective Dec 24, 2025Mixed actions
The FAA is adopting a new airworthiness directive (AD) for all aircraft equipped with certain Aerospace & Defense Oxygen Systems SaS portable breathing equipment (PBE). This AD was prompted by reports of occurrences of incorrect usage of certain PBEs. This AD requires incorporating revised procedures for donning the PBE. The FAA is issuing this AD to address the unsafe condition on these products.

Directives citing this part number in the FAA / EASA regulatory corpus we have processed — not a complete historical AD list. An AD is a compliance requirement that drives scheduled work (inspections, replacements, modifications) on the fleets that carry the part; a directive naming this PN as the replacement part is install demand, not an action against it — and none of this is a prediction that the part will fail.
