Airworthiness Directives; Eurocopter France (Eurocopter) Model SE 3130, SE 313B, SA 3180, SA 318B, and SA 318C Helicopters

요약

This amendment adopts a new airworthiness directive (AD) that is applicable to Eurocopter Model SE 3130, SE 313B, SA 3180, SA 318B, and SA 318C helicopters. This action requires a visual inspection of the main rotor blade reinforcement strips for debonding between the reinforcement strips of the blade; and a visual inspection of the main rotor blade (blade) skin for cracks or corrosion, and replacement of the blade with an airworthy blade if certain debonding or a crack or corrosion is found. This amendment is prompted by an accident in which a blade separated in flight. The actions specified in this AD are intended to detect debonding, cracks, or corrosion in the affected blades and to prevent failure of a blade and subsequent loss of control of the helicopter.
