Airworthiness Directives; Fokker Services B.V. Airplanes

Краткое содержание

We propose to adopt a new airworthiness directive (AD) for all Fokker Services B.V. Model F28 Mark 0070 and 0100 airplanes. This proposed AD was prompted by reports of electrical arcing between the auxiliary power unit (APU) starter motor positive terminal and the APU fuel drain line. This proposed AD would require the removal of certain clamps and replacement of the flexible APU fuel drain line. We are proposing this AD to address the unsafe condition on these products.
