Airworthiness Directive · Amendment 39-23120 · Main rotor control
Leonardo S.p.A. Helicopters
This AD applies to Leonardo S.p.A. Model A109A, A109A II, A109C, A109K2, A119, and AW119 MKII helicopters, certificated in any category, as identified in European Union Aviation Safety Agency (EASA) AD 2025-0142, dated July 7, 2025 (EASA AD 2025-0142).
The FAA is adopting a new airworthiness directive (AD) for all Leonardo S.p.A. Model A109A, A109A II, A109C, A109K2, and A119 helicopters and certain AW119 MKII helicopters. This AD was prompted by a report of incorrect installation of the bolts that attach the pitch (longitudinal) actuator assembly and the roll (lateral) actuator assembly to their respective bellcrank assemblies of the cyclic control system. This AD requires inspecting the bolts for proper installation and, depending on the results, performing corrective actions. 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, EASA AD 2025-0142.
(1) Where EASA AD 2025-0142 refers to its effective date, this AD requires using the effective date of this AD.
(2) Where EASA AD 2025-0142 refers to flight hours, this AD requires using hours time-in-service.
(3) Where EASA AD 2025-0142 refers to damage or damaged, for this AD, damage means any wear.
(4) Where paragraph (3) of EASA AD 2025-0142 states “contact Leonardo for approved corrective action instructions and accomplish those instructions accordingly”, this AD requires replacing that text with “repair the discrepancy using a method approved by the Manager, International Validation Branch, FAA; or EASA; or Leonardo Helicopters' EASA Design Organization Approval (DOA). If approved by the DOA, the approval must include the DOA-authorized signature”.
(5) Where paragraph (6) of EASA AD 2025-0142 states “From the effective date of this AD, do not accomplish any maintenance action on a helicopter in accordance with Leonardo maintenance instructions as listed in Table 1 of this AD”, this AD requires replacing that text with “After the effective date of this AD, revise the existing maintenance or inspection program to prohibit the use of the Leonardo maintenance instructions listed in Table 1 of EASA AD 2025-0142”.
(6) This AD does not adopt the “Remarks” section of EASA AD 2025-0142.
Although the material referenced in EASA AD 2025-0142 specifies to submit certain information to the manufacturer, this AD does not require that action.
