Airworthiness Directive · Amendment 39-22056 · Rotorcraft flight control
Leonardo S.p.a. Helicopters
This AD applies to Leonardo S.p.a. Model A109S helicopters, serial number (S/N) 22735, 22736, and 22737, and equipped with Trekker Kit; and Model AW109SP helicopters S/N 22407, 22408, 22409, 22412, 22414 through 22427 inclusive, and 22429, certificated in any category.
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 a report of a protective sheath, installed around a fixed flight control rod, which should have been removed during assembly. This AD requires borescope inspecting certain parts, and removing any foreign object if detected, 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, European Union Aviation Safety Agency (EASA) AD 2021-0255, dated November 15, 2021, and corrected November 24, 2021 (EASA AD 2021-0255).
(1) Where EASA AD 2021-0255 requires compliance in terms of flight hours, this AD requires using hours time-in-service.
(2) Where EASA AD 2021-0255 refers to its effective date, this AD requires using the effective date of this AD.
(3) Where paragraph (1) of EASA AD 2021-0255 specifies “inspect each affected part in accordance with the instructions of the applicable ASB,” for this AD replace “in accordance with the instructions of the applicable ASB” with “in accordance with the Accomplishment Instructions, Section 3, paragraph 5. of the applicable ASB.”
(4) Where paragraph (2) of EASA AD 2021-0255 specifies “if, during the inspection as required by paragraph (1) this AD, any foreign object is found on an affected part, before next flight, remove that foreign object in accordance with the applicable ASB,” this AD requires if any foreign object is found, before further flight, remove the foreign object. The instructions in the “applicable ASB” are for reference only and are not required for the actions in paragraph (2) of EASA AD 2021-0255.
(5) This AD does not mandate compliance with the “Remarks” section of EASA AD 2021-0255.
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.
