## Summary

We propose to supersede 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 currently requires 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 requires revising the airplane maintenance program. Since we issued AD 2011-17-10, revised service information has been issued to update the critical design configuration control limitations (CDCCLs) that address potential ignition sources inside fuel tanks. This proposed AD would require revising the airplane maintenance or inspection program by incorporating the instructions in the revised service information. The proposed AD also removes certain airplanes from the applicability. We are proposing 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.
