Airworthiness Directives; Eurocopter France Helicopters

Streszczenie

We propose to adopt a new airworthiness directive (AD) for Eurocopter France EC130B4 helicopters. This proposed AD is prompted by an in-flight cracking and failure of a center windscreen. The proposed actions are intended to detect a crack in the blending radii of the center windscreen to prevent failure of the windscreen, injury to the flight crew, and subsequent loss of control of the helicopter.
