## Abstract

The FAA is adopting a new airworthiness directive (AD) for certain Airbus Helicopters Model EC225LP helicopters. This AD requires determining the total hours time-in-service (TIS) of the free wheel shafts of certain main rotor gearboxes (MGBs), replacing the MGB or right-hand side (RH) free wheel shaft, installing placard(s), and revising the Rotorcraft Flight Manual (RFM) for your helicopter. This AD was prompted by a report of wear of the ramps of the RH free wheel shaft. The actions of this AD are intended to address an unsafe condition on these products.
