Summary
The FAA proposes the adoption of a new airworthiness directive (AD) for Agusta S.p.A. Model A109E helicopters. The proposed AD would require modifying the passenger compartment sliding doors by installing certain locking mechanism kits. The proposed AD is prompted by accidental opening of a passenger compartment sliding door (door) inflight due to a door locking mechanism that is too easy to accidentally open. The actions specified by the proposed AD are intended to prevent accidental opening of a door in flight and subsequent loss of objects that could damage the rotor system.
