Airworthiness Directive · Amendment 39-23214 · Main rotor blades
Airbus Helicopters
This AD applies to Airbus Helicopters Model SA341G and SA342J helicopters, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model SA341G and SA342J helicopters. This AD was prompted by reports of disbonding of the stainless steel leading edge protection of certain part-numbered main rotor blades (MRB). This AD requires repetitively tap inspecting the MRB and, depending on the results, repairing or replacing the MRB. This AD also prohibits installing those MRB unless certain requirements are met. The FAA is issuing this AD to address the unsafe condition on these products.
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 2023-0155, dated July 31, 2023 (EASA AD 2023-0155).
(1) Where EASA AD 2023-0155 requires compliance in terms of flight hours, this AD requires using hours time-in-service.
(2) Where EASA AD 2023-0155 refers to its effective date, this AD requires using the effective date of this AD.
(3) Where the material referenced in paragraph (2) of EASA AD 2023-0155 specifies sending removed blade(s) to Airbus Helicopters, this AD does not require that action.
(4) This AD does not adopt the “Remarks” section of EASA AD 2023-0155.
Although the material referenced in EASA AD 2023-0155 specifies to submit certain information to the manufacturer, this AD does not include that requirement.
