Abstract
This amendment adopts a new airworthiness directive (AD) that is applicable to certain Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-135 and EMB-145 series airplanes. This action requires revising the FAA-approved Airplane Flight Manual to prohibit in-flight auxiliary power unit (APU) starts, and installing a placard on or near the APU start/stop switch panel to provide such instructions to the flight crew. This action is necessary to prevent flame backflow into the APU compartment through the eductor during in-flight APU starts, which could result in fire in the APU compartment. This action is intended to address the identified unsafe condition.
