Summary
This document proposes adopting a new airworthiness directive (AD) for the specified Eurocopter France (Eurocopter) model helicopters. This proposal would require inspecting the fuel air vent hoses (air vent hoses) for chafing and fuel leakage in the interference areas, inspecting the length of the latch support attachment screws, installing spacers to prevent interference with the latch support attachment screws, and removing one tyrap clamp support. This proposal is prompted by a report of a fuel leak in the air vent hose at the 9o frame on the pilot's side of the helicopter. The actions specified by this proposed AD are intended to prevent fuel leakage, toxic fumes inside the cabin creating a fire hazard that could lead to a fire and smoke in the cabin, and subsequent loss of control of the helicopter.
