Leonardo S.p.A. Helicopters
This AD applies to Leonardo S.p.A. helicopters identified in paragraphs (c)(1) through (4) of this AD, certificated in any category.
(1) Model A109E helicopters, all serial numbers (S/N).
(2) Model A109S helicopters without Trekker Kit part number (P/N) 109G0000F01 installed, all S/Ns.
(3) Model A109S helicopters with Trekker Kit P/N 109G0000F01installed, S/N 22202, 22088, 22701 through 22741 inclusive, 22743 through 22746 inclusive, and 22748.
(4) Model AW109SP helicopters, S/N 22201, 22203, 22214 through 22362 inclusive, 22364 through 22460 inclusive, and 22462 through 22464 inclusive.
The FAA is adopting a new airworthiness directive (AD) for certain Leonardo S.p.A. Model A109E, A109S, and AW109SP helicopters. This AD was prompted by reports of incorrect installation of the motor (MTR) cables and the bonding braids connected to the engine fire extinguisher bottles. This AD requires inspecting the cables and bonding braids installation and, depending on the results, accomplishing corrective action, 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 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 2024-0193, dated October 11, 2024 (EASA AD 2024-0193).
(1) Where EASA AD 2024-0193 requires compliance in terms of flight hours, this AD requires using hours time-in-service.
(2) Where EASA AD 2024-0193 refers to its effective date, this AD requires using the effective date of this AD.
(3) Where paragraph (2) of EASA AD 2024-0193 states “any discrepancy,” this AD requires replacing that text with “an improper installation.”
(4) This AD does not adopt the “Remarks” section of EASA AD 2024-0193.
Although the material referenced in EASA AD 2024-0193 specifies to submit certain information to the manufacturer, this AD does not require that action.
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.
