AD 2026-16-03 Airworthiness Directives; Airbus Helicopters
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 2025-0052, dated February 28, 2025 (EASA AD 2025-0052).
Unsafe condition
This AD was prompted by reports of cracks in the legs of the side support of the tail rotor transmission fan. The FAA is issuing this AD to detect and correct a cracked side support of the tail rotor transmission fan. The unsafe condition, if not addressed, could result in failure of the legs supporting the tail rotor transmission fan and displacement of the tail rotor transmission fan assembly, which could lead to the failure of the engine and main gearbox cooling function, loss of the tail rotor drive, and consequent loss of control of the helicopter.
Affected ADs
None.
