Eurocopter France (ECF) Model EC120B Helicopters: Airworthiness Directive Amendment
The Federal Register publishes an amendment to Airworthiness Directive (AD) 2010-05-51, which requires U.S. owners and operators of ECF Model EC120B helicopters to inspect the main rotor head rotor hub for cracks at specified intervals, and replace it if found damaged, following an investigation by the European Aviation Safety Agency (EASA) into an emergency landing due to excessive vibrations.
