Airworthiness Directives; Fokker Services B.V. Airplanes
We are superseding Airworthiness Directive (AD) 2011-17-10, for all Fokker Services B.V. Model F.28 Mark 1000, 2000, 3000, and 4000 airplanes. AD 2011-17-10 required inspecting for a by-pass wire between the housing of each in-tank fuel quantity indication (FQI) cable plug and the cable shield, and corrective actions if necessary. AD 2011-17- 10 also required revising the airplane maintenance program. This new AD removes certain airplanes from the applicability. This new AD applies only to Model F.28 Mark 1000 airplanes and also requires revising the airplane maintenance or inspection program by incorporating the instructions in revised service information. This AD was prompted by the issuance of revised service information to update the critical design configuration control limitations (CDCCLs) that address potential ignition sources inside fuel tanks. We are issuing this AD to prevent potential ignition sources inside the fuel tanks, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.
