## Abstract

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