## Summary

We propose to adopt a new airworthiness directive (AD) for Airbus Helicopters Model EC225LP helicopters. This proposed AD would require modifying the emergency lubrication system (EMLUB). This proposed AD is prompted by two incidents of emergency ditching after there was a warning of a loss of oil pressure and a false EMLUB failure. The proposed actions are intended to address an unsafe condition on these products.
