Models named: AS355E, AS355F, AS355F1, AS355F2, AS355N. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
This AD applies to all Airbus Helicopters Model AS355E, AS355F, AS355F1, AS355F2, and AS355N helicopters, certificated in any category.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
Except as specified in paragraphs (h) and (i) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, European Union Aviation Safety Agency AD 2024-0127, dated July 3, 2024 (EASA AD 2024-0127).
Unsafe condition
This AD was prompted by the determination that the tail rotor drive fan wheel and impeller second stage have been incorrectly identified during production. The FAA is issuing this AD to detect and address incorrect identification of the affected parts. The unsafe condition, if not addressed, may cause the loss of traceability of the affected parts, which could lead to undetected fatigue failure of the affected parts and result in loss of control of the helicopter.
Affected ADs
None.
