AGENCY:
Federal Aviation Administration (FAA), DOT.
ACTION:
Final rule; request for comments.
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.
DATES:
This AD is effective March 31, 2026.
The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of March 31, 2026.
The FAA must receive comments on this AD by April 30, 2026.
