Airworthiness Directives; Fokker Services B.V. Airplanes

We are superseding Airworthiness Directive (AD) 2008-06-20 R1, which applied to all Fokker Services B.V. Model F28 Mark 0070 and 0100 airplanes, and certain Model F28 Mark 1000, 2000, 3000, and 4000 airplanes. AD 2008-06-20 R1 required revising the Airworthiness Limitations Section (ALS) of the Instructions for Continued Airworthiness for certain airplanes, and the maintenance or inspection program, as applicable, for certain other airplanes, to incorporate new limitations for fuel tank systems. AD 2008-06-20 R1 also clarified the intended effect on spare and on-airplane fuel tank system components, regarding the use of maintenance manuals and instructions for continued airworthiness. This new AD was prompted by revised fuel airworthiness limitation items (ALI) tasks, and critical design configuration control limitations (CDCCL) items, and associated thresholds, intervals, and instructions. This AD requires contacting the FAA to obtain instructions for addressing the unsafe condition on these products, and doing the actions specified in those instructions. We are issuing this AD to address the unsafe condition on these products.
