Airworthiness Directive · Amendment 39-23289 · Placards and markings
Leonardo S.p.a. Helicopters
This AD applies to Leonardo S.p.a. Model AB139 and AW139 helicopters having serial number 31087, 31133, 31269, 31305, 31351, 31502, 31712, 31735, 31757, 31865, 31869, 41582 and 41583, certificated in any category, modified in accordance with Supplemental Type Certificate (STC) SR00049IB.
The FAA is adopting a new airworthiness directive (AD) for certain Leonardo S.p.a. Model AB139 and AW139 helicopters with a certain supplemental type certificate (STC) installed. This AD was prompted by the absence of instructions on the information placards located next to the rear-facing seats to lock the seat headrest in the highest position during takeoff and landing. This AD requires revising the existing rotorcraft flight manual supplement (RFMS) and replacing the information placard with one that specifies instructions for locking the seat headrest. 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 2024-0088, dated April 15, 2024; corrected May 14, 2024 (EASA AD 2024-0088).
(1) Where EASA AD 2024-0088 refers to its effective date, this AD requires using the effective date of this AD.
(2) Where EASA AD 2024-0088 specifies compliance in terms of flight hours, this AD requires using hours time-in-service.
(3) This AD does not adopt the “Remarks” section of EASA AD 2024-0088.
Although the material referenced in EASA AD 2024-0088 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.
