EASA AD CF-2023-52
Oxygen — Portable Oxygen Bottles — Oxygen Masks Not Connected to Oxygen Bottles After Servicing
Summary
The Canadian Airworthiness Directive CF-2023-52 addresses an issue with portable oxygen bottles and oxygen masks on certain Airbus Canada Limited Partnership aircraft models BD-500-1A10 and BD-500-1A11. It mandates inspection and correction of oxygen masks that are not connected to their respective portable oxygen bottles after maintenance. This directive ensures proper oxygen supply to cabin crew and passengers during decompression or emergency situations.
What Changed
CF-2023-52 introduces a mandatory inspection and corrective action requirement to verify that oxygen masks are properly connected to portable oxygen bottles on specified Airbus Canada aircraft. This follows findings during production flight tests that revealed some masks were not connected due to missing maintenance instructions. The directive enforces compliance with a previously issued service bulletin that had not been fully implemented fleet-wide.
Why It Matters
This directive is critical for aviation professionals because unconnected oxygen masks pose a serious safety risk during sudden decompression or medical emergencies at altitude. Operators and maintenance organizations must ensure compliance to maintain airworthiness and passenger safety. Failure to comply could result in regulatory penalties and increased risk during in-flight emergencies.
What To Do
Operators of affected Airbus Canada BD-500-1A10 and BD-500-1A11 aircraft must inspect portable oxygen bottles and connect any disconnected oxygen masks in accordance with Airbus Canada Service Bulletin BD500-353001, edition 001 or later approved revisions. These actions must be completed within six months from the directive's effective date of July 26, 2023.
