Abstract
We are adopting a new airworthiness directive (AD) for Eurocopter France (Eurocopter) Model AS332C, AS332L, AS332L1, AS332L2, and EC225LP helicopters. This AD requires inspecting the intermediate gearbox (IGB) fairing for a crack and inspecting the IGB fairing gutter (gutter), if installed, for a crack, separation, or interference. This AD is prompted by reports of cracks, separation of the IGB fairing from the gutter and attachment supports, and subsequent interference with the tail rotor (T/R) inclined drive shaft. These actions are intended to detect a crack and prevent separation of the IGB fairing, which could result in interference with the T/R inclined drive shaft and subsequent loss of control of the helicopter.
