### ATA 28 Fuel – Collector Tank Level Float Switch Wiring – Modification [Fuel Tank Safety]

Manufacturer(s): Fokker Aircraft B.V. (and predecessor companies)

Applicability: F28 Mark 1000, 1000C, 2000, 3000, 3000C, 3000R, 3000RC and 4000 aeroplanes, all serial numbers.

Reason: Prompted by an accident of a Boeing 74 7-131 (flight TWA800), the Federal Aviation Administration (FAA) has published Special Federal Aviation Regulation (SFAR) 88, and the Joint Aviation Authorities (JAA) has published Interim Policy INT/POL/25/12. The review conducted by Fokker Services on the Fokker F28 Type Design in response to these regulations revealed that, under certain failure conditions, a short circuit may develop in the collector tank level float switch wiring. Such a short circuit may result in an ignition source in the tank vapour space. This condition, if not corrected, could re sult in a wing fuel tank explosion and consequent loss of the aeroplane. For the reasons described above, this AD requires the installation of a fuse packed in a jiffy junction in the collector tank level float switch wiring.
