## Abstract

This amendment adopts a new airworthiness directive (AD) for Eurocopter France Model EC 155B helicopters. This AD requires, before each takeoff with a cabin sliding door in the open position, visually checking each sliding door to ensure that each door roller is inside its rail. If a roller is outside its rail, before further flight, each roller on each door must be replaced inside its rail. This AD also revises the Limitations section of the Rotorcraft Flight Manual (RFM) by prohibiting the opening and closing of a cabin sliding door in flight. This AD is prompted by the loss of a cabin sliding door in flight. 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.
