Airworthiness Directives; AvCraft Dornier Model 328-100 Airplanes

The FAA is adopting a new airworthiness directive (AD) for all AvCraft Dornier Model 328-100 airplanes. This AD requires modifying the electrical wiring of the fuel pumps; installing insulation at the hand flow control and shut-off valves, and other components of the environmental control system; and installing markings at fuel wiring harnesses. This AD also requires revising the Airworthiness Limitations section of the Instructions for Continued Airworthiness to incorporate new inspections of the fuel tank system. This AD is prompted by the results of fuel system reviews conducted by the airplane manufacturer. We are issuing this AD to reduce the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.
