Abstract
This amendment adopts a new airworthiness directive (AD), applicable to Eurocopter France Model AS 332C, L, and L1 helicopters that requires replacing main rotor blades with modified main rotor blades. This amendment is prompted by reports of an investigation that found broken braids on main rotor blade de-icers. The actions specified by this AD are intended to prevent loss of deicing capabilities of the main rotor blades, adverse performance during flight in icing conditions, and subsequent loss of control of the helicopter.
