2016-11096: Airworthiness Directives; ATR-GIE Avions de Transport Régional Airplanes

Summary

We are revising an earlier proposed airworthiness directive (AD) for certain ATR--GIE Avions de Transport R[eacute]gional Model ATR42-500 and Model ATR72-212A airplanes. The NPRM proposed to require measuring the gap between the Type III Emergency Exit doors and certain overhead stowage compartment fittings; removing certain fittings from the overhead stowage compartments and measuring the gap between the Type III Emergency Exit doors and the overhead stowage compartment hooks, if necessary; and re-installing or repairing, as applicable, the Type III Emergency Exit doors. The NPRM was prompted by a report indicating that interference occurred between a Type III Emergency Exit door and the surrounding passenger cabin furnishing during a production check. This action revises the NPRM by adding new proposed requirements for modifying the overhead stowage compartments. We are proposing this supplemental NPRM (SNPRM) to prevent interference between a Type III Emergency Exit door and the overhead stowage compartment fitting installed on the rail; which could result in obstructed opening of a Type III Emergency Exit door during an emergency evacuation. Since these actions impose an additional burden over those proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes.
