Summary
We propose to adopt a new airworthiness directive (AD) for all Fokker Services B.V. Model F.28 Mark 0070 and 0100 airplanes. This proposed AD was prompted by the need for more restrictive fuel airworthiness limitations. This proposed AD would require revising the maintenance program or inspection program, as applicable, to incorporate certain fuel system airworthiness limitations. We are proposing 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.
