AD 2023-23-01 Airworthiness Directives; Airbus Helicopters
Models named: EC130T2. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
This AD applies to Airbus Helicopters Model EC130T2 helicopters, certificated in any category, as identified in European Union Aviation Safety Agency (EASA) AD 2023-0028, dated February 1, 2023 (EASA AD 2023-0028).
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
Except as specified in paragraph (h) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, EASA AD 2023-0028.
Unsafe condition
This AD was prompted by a report of degradation of the rear transmission shaft bearing support and the determination that all the attachment rivets of the transmission shaft bearing support were sheared. Also, it has been reported that some attachment rivets of the transmission shaft bearing may have been painted over, preventing detection of this unsafe condition. The FAA is issuing this AD to address sheared attachment rivets of the transmission shaft bearing support. This condition, if not addressed, could lead to failure of the tail rotor drive shaft and subsequent loss of yaw control of the helicopter.
Affected ADs
This AD replaces AD 2022-01-05, Amendment 39-21893 (86 FR 74353, December 30, 2021) (AD 2022-01-05).
