Summary
We propose to adopt a new airworthiness directive (AD) for Airbus Helicopters Model EC225LP, AS332C, AS332L, AS332L1, and AS332L2 helicopters. This proposed AD would require inspecting each TECALEMIT flexible hydraulic hose (hose) installed in the main gearbox (MGB) compartment and replacing the hose if a crack, cut, or other damage exists. This proposed AD is prompted by reports about the loss of in- flight hydraulic pressure on Eurocopter helicopters. The proposed actions are intended to prevent loss of the hydraulic system and consequently, loss of helicopter control.
