Final rule.

We are adopting a new airworthiness directive (AD) for Eurocopter France (Eurocopter) Model EC225LP helicopters. This AD requires inspecting the swashplates for corrosion or a crack, and making the appropriate repairs or replacement of parts. This AD was prompted by the discovery of corrosion on the swashplates when the main rotor hub (MRH) assemblies were reconditioned. The actions of this AD are intended to detect corrosion or a crack in the swashplates, which could lead to failure of the swashplates and subsequent loss of helicopter control.
