## Abstract

This amendment supersedes an airworthiness directive (AD) for Eurocopter France Model EC 155B helicopters that currently requires, before each flight, visually checking each sliding door to ensure that each door roller is inside its rail. This amendment requires modifying the cabin sliding door rails and replacing the roller fitting. This amendment is prompted by the development of a modification that mechanically restrains the roller within its rail. The actions specified by this AD are intended to prevent in-flight loss of a cabin sliding door, impact with the main rotor or fenestron, and subsequent loss of control of the helicopter.
