AD 96-10-05 61 FR 20125 Active

This amendment adopts a new airworthiness directive (AD) that applies to certain Maule Aerospace Technologies, Inc. (Maule) Models M- 4-210 and M-4-210C airplanes that have Dual Exhaust System 5230F installed. This action requires relocating the gascolator and electric fuel pump away from the dual exhaust system. The Federal Aviation Administration (FAA) recently became aware that, with these dual exhaust systems installed on the affected airplanes, the left-hand exhaust stack is routed almost directly below the fuel gascolator. The close proximity of the flammable fuel to the exhaust system presents an unsafe condition and violates current regulations. The actions specified by this AD are intended to prevent an airplane engine fire caused by the close proximity of the fuel gascolator and electric fuel pump to the exhaust system.
