Aerospatiale Model ATR72 Series Airplanes
Model ATR72 series airplanes, certificated in any category; except those airplanes on which modification 5297 has been accomplished in production, or on which Avions de Transport Regional (ATR) Service Bulletin ATR72-92-1006, dated September 28, 2001, has been accomplished in service.
This amendment adopts a new airworthiness directive (AD), applicable to certain Aerospatiale Model ATR72 series airplanes, that requires installing brackets and ramps under floor panels between frames 23C and 23D and installing wire bundles on the ramps. The actions specified by this AD are intended to prevent chafing damage to the electrical wire cables, which could lead to an electrical short circuit and potential for a fire under the floor panels. This action is intended to address the identified unsafe condition.
