## Abstract

The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model EC225LP helicopters. This AD was prompted by reports of an oil leak from the main gearbox (MGB) during engine start up. This AD requires modifying and performing subsequent repetitive function testing of the MGB emergency lubrication (EMLUB) system as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference (IBR). The FAA is issuing this AD to address the unsafe condition on these products.
