Abstract
The FAA is superseding Airworthiness Directive (AD) 2019-03-12 for certain Airbus Helicopters Model EC225LP helicopters. AD 2019-03-12 required repetitively inspecting, cleaning, and lubricating each life raft inflation cylinder percussion system bellcrank (bellcrank). This new AD continues to require the actions specified in AD 2019-03-12, and requires replacing any affected bellcrank with a serviceable bellcrank, which terminates the repetitive actions. This AD was prompted by reports of jammed bellcranks in the life raft jettison inflation cylinder percussion system. The actions of this AD are intended to address an unsafe condition on these products.
