EASA AD 2021-0218-CN
CANCELLED: Oxygen — Crew and Passenger Oxygen Cylinders — Inspection / Replacement
Summary
EASA Airworthiness Directive 2021-0218-CN is a cancellation notice issued by the European Union Aviation Safety Agency for ATR 42 and ATR 72 aeroplanes. It cancels the previous AD 2021-0218, which addressed inspection and replacement of certain oxygen cylinders used in crew and passenger oxygen systems. The affected parts included specific batches of oxygen cylinders with part numbers 89794077 and 891311-14 that were subject to inspection due to a manufacturing defect.
What Changed
This document cancels EASA AD 2021-0218, which required inspections and possible replacement of affected oxygen cylinders on ATR 42 and ATR 72 aircraft. The cancellation follows the adoption of FAA AD 2023-13-11 by EASA, which now covers all the requirements previously mandated by EASA AD 2021-0218. No further actions are required under this cancelled directive.
Why It Matters
The cancellation of EASA AD 2021-0218 means that operators and maintenance organizations for ATR 42 and ATR 72 aircraft should now follow FAA AD 2023-13-11 for compliance regarding oxygen cylinder inspections and replacements. This streamlines regulatory requirements and avoids duplication of efforts, ensuring continued safety without redundant directives. It is important for compliance teams to update their records and maintenance programs accordingly.
What To Do
Affected stakeholders should discontinue compliance with EASA AD 2021-0218 and instead comply with FAA AD 2023-13-11 for inspection and replacement of the specified oxygen cylinders. There are no new compliance deadlines from this cancellation notice, but operators must adhere to the deadlines specified in FAA AD 2023-13-11.
