Airworthiness Directive · Amendment 39-21844 · Electrical power system wiring
Leonardo S.p.a. Helicopters
This AD applies to Leonardo S.p.a. Model A109S and AW109SP helicopters, certificated in any category, as identified in European Union Aviation Safety Agency (EASA) AD 2021-0065, dated March 8, 2021 (EASA AD 2021-0065).
The FAA is adopting a new airworthiness directive (AD) for certain Leonardo S.p.a. Model A109S and AW109SP helicopters. This AD was prompted by the discovery that rubber protection of certain electrical wiring had not been installed in the baggage avionics bay during production. This AD requires installing protective rubber borders on the edge of the baggage avionics bay frames, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
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 2021-0065.
(1) Where EASA AD 2021-0065 requires compliance in terms of flight hours, this AD requires using hours time-in-service.
(2) Where EASA AD 2021-0065 refers to its effective date, this AD requires using the effective date of this AD.
(3) This AD does not mandate compliance with the “Remarks” section of EASA AD 2021-0065.
Although the service information referenced in EASA AD 2021-0065 specifies to submit certain information to the manufacturer, this AD does not include that requirement.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
