Regulation

Airworthiness Directives; Leonardo S.p.a. Helicopters

Passed / Signedtransportation

Introduced: March 16, 2026

Progress

Summary

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.
