Summary

We propose to supersede Airworthiness Directive (AD) 2008-05- 18 R1 for certain Fokker Services B.V. Model F.27 Mark 050, 200, 300, 400, 500, 600, and 700 airplanes. AD 2008-05-18 R1 currently requires revising the Airworthiness Limitations Section (ALS) of the Instructions for Continued Airworthiness to incorporate new limitations for fuel tank systems. Since we issued AD 2008-05-18 R1, revised service information has been issued to update the Fuel Airworthiness Limitations Items (ALIs) and critical design configuration control limitations (CDCCLs) that address fuel tank system ignition sources. This proposed AD would require a new maintenance or inspection program revision to incorporate the revised ALIs and CDCCLs. This proposed AD would add certain airplanes to the applicability. We are proposing this AD to prevent 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.
