Airworthiness Directive · Amendment 39-19525 · Airborne auxiliary power
Fokker Services B.V. Airplanes
This AD applies to Fokker Services B.V. Model F28 Mark 0070 and 0100 airplanes, certificated in any category, all serial numbers.
We are adopting a new airworthiness directive (AD) for all Fokker Services B.V. Model F28 Mark 0070 and 0100 airplanes. This 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 AD requires the removal of certain clamps and replacement of the flexible APU fuel drain line. We are issuing this AD to address the unsafe condition on these products.
Within 12 months after the effective date of this AD: Remove the two additional clamps, part number (P/N) MS21919WCH5 and P/N MS21919WCH13, and replace APU fuel drain line P/N D67066-409 with a new APU fuel drain line P/N W67066-401, in accordance with the Accomplishment Instructions of Fokker Service Bulletin SBF100-49-037, dated October 31, 2016.
Accomplishing the actions required by paragraph (g) of this AD terminates all requirements of AD 95-21-20.
