## Summary

We propose to adopt a new airworthiness directive (AD) for Eurocopter France (Eurocopter) Model AS332C, AS332L, AS332L1, AS332L2, and EC225LP helicopters. This proposed AD would require 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 proposed 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 (TR) inclined drive shaft. The proposed actions are intended to detect a crack and prevent separation of the IGB fairing, which could result in interference with the TR inclined drive shaft and subsequent loss of control of the helicopter.
