What the agency says
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Model EC225LP helicopters. This proposed 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 proposed AD would also require inspecting certain M/R mast cover plates and accomplishing MGB oil analyses and, depending on the results, replacing the M/R mast cover plate, accomplishing an additional inspection, or replacing the MGB. This proposed AD would also prohibit installing certain M/R mast upper stops assembly screws, M/R masts with an affected M/R mast upper stops assembly screw installed, or used M/R mast cover plates on any helicopter. Lastly, this proposed AD would prohibit 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 proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.
