Airworthiness Directives; Eurocopter France Model SA330F, G, and J Helicopters

概要

This amendment supersedes an existing airworthiness directive (AD) that applies to Eurocopter France Model SA330F, G, and J helicopters and requires inspecting the tail rotor blade (blade) skin for cracks and replacing, as necessary, the blade. This amendment requires skin bonding and eddy current inspections of the blade skin for cracks and would reference a more recent service bulletin (SB). This amendment is prompted by improved inspection methods and by the manufacturer revising the SB referenced in the current AD. The actions specified by this AD are intended to prevent fatigue cracking of a blade, failure of a blade, and subsequent loss of control of the helicopter.
