## Summary

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