Airworthiness Directives; Eurocopter France Helicopters
We are adopting a new airworthiness directive (AD) for Eurocopter France (Eurocopter) Model EC120B and EC130B4 helicopters with a certain emergency flotation gear (float) installed. This AD requires inspecting the float for chafing of the fabric covering and adding protectors to the float installation to prevent contact between the float and the protruding sections of the installation. This AD was prompted by a report of a float that would not inflate during overhaul because one of the float compartments was punctured due to chafing. The actions of this AD are intended to prevent failure of float and subsequent loss of control of the helicopter during an emergency water landing.
