Abstract
The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model EC225LP helicopters. This AD was prompted by a report of water in the oil of a main gearbox (MGB). This AD requires replacing certain main rotor (M/R) mast upper stops assembly screws. This AD also requires inspecting certain M/R mast cover plates and accomplishing MGB oil analyses and, depending on the results, taking corrective action. This AD prohibits installing certain M/R mast upper stops assembly screws, M/R masts with an affected M/R mast upper stops assembly screw installed, and used M/R mast cover plates on any helicopter. Lastly, this AD prohibits installing affected M/R masts unless the inspections are done. These actions are specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
