Planning Information A. Effectivity (1) F28 Mark 1000 through 4000 aircraft serial number(s): 11003 thru 11241, 11991 and 11992. (2) Production version of this change: Not applicable. B. Concurrent Requirements (1) Before, or at the same time as, you do this Service Bulletin Appendix, you must do: - SBF28-28-049 - FUEL - General - The introduction of a Fuse in the Collector Tank Level Float Switch Wiring. - SBF28-28-051 - FUEL - General - The Introduction of a Fuse in the Level Control Pilot Valve Wiring. C. Reason (1) The design review of the F28 Mk 1000 thru 4000 fuel system, in accordance with the guidelines related to FAA SFAR 88 and JAA INT/POL/25/12, revealed that an unsafe condition may develop in the wing tanks. (2) Under certain failure conditions of the Solenoid of the Level Control Pilot Valve, the Main Tank Overflow Valve Reed Switch, the Collector Tank Level Float Switch or the Main Tank Fueling Shut-Off Valve Solenoid, a short circuit may develop. Such a short circuit may result in an ignition source in the wing tank vapor space. (3) Fuses, packed in a fuse assembly will limit the current and thus prevent this ignition source in the wing tank vapor space. D. Description (1) This Service Bulletin Appendix is divided in four (4) Parts as follows: Part 1: Installation of fuse assembly for the Level Control Pilot Valve Solenoid. This Part tells you how to: - Install a fuse assembly (with 1A fuse) in the return wire of the Level Control Pilot Valve Solenoid, close to tank entry point. - Perform system functional tests. Part 2: Installation of fuse assembly for Main Tank Overflow Valve Reed Switch. This Part tells you how to: - Install fuse assemblies (with 0.25A fuse) in the signal and return wires of the Main Tank Overflow Valve Reed Switch, close to tank entry point. - Perform system functional tests.
