Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-120 Series Airplanes
Model EMB-120 series airplanes as listed in EMBRAER Service Bulletin 120-25-0264, Change 01, dated July 22, 2002; certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain EMBRAER Model EMB-120 series airplanes, that requires either revising the Airplane Flight Manual (AFM) to require a maximum operating altitude of 25,000 feet; or modifying the flight attendant's seat or reworking the oxygen bottle kit, as applicable, and revising the AFM to require a maximum operating altitude of 30,000 feet. This action is necessary to prevent the unavailability of supplemental oxygen to the flight attendant in the event of cabin decompression, which could result in loss of consciousness of the flight attendant. This action is intended to address the identified unsafe condition.
