2. Planning Information

A. Effectivity 

(1) F28 Mark 0070/0100 aircraft serial number(s): 

11244 thru 11585, if equipped with a Center Wing Tank. 

NOTE: aircraft s/n 11567, on which Technical Operational Variation TOV-00922 

was incorporated, is compliant with this Service Bulletin. 

B. Concurrent Requirements 

(1) Not applicable. 

C. Reason 

(1) The design review of the F28 Mk 0070/0100 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 center tanks. 

(2) Under certain failure conditions of the wiring of the Maximum Level Sensors, a 

short circuit may develop that causes a hot spot on the wiring conduit or puncturing 

of the wall of the wiring conduit in the tank. This may result in an ignition source in 

the center tank vapor space. 

(3) Fuses, packed in a jiffy junction will limit the current and thus prevent this ignition 

source in the center tank vapor space. 

D. Description 

(1) This Service Bulletin is divided in five Parts as follows: 

Part 1: Removal of one (1) Fuse in the Wiring of the Max Level Sensor on the 

Fuel Quantity Probe in the Center Wing Bag Tank (CWBT). 

(Applicable for aircraft serial number 11244 up to and including 11441, if 

in the POST SBF100-28-073 configuration) 

This Part tells you how to: 

- Remove a fuse in the Max Level sensor Wiring on the Fuel 

Quantity Probe of the CWBT. 

Part 2: Installation of two (2) Fuses in the Wiring of the Max Level Sensor on the 

Fuel Quantity Probe in the Center Wing Bag Tank (CWBT). 

(Applicable for aircraft serial number 11244 up to and including 11441, if 

in the PRE SBF100-28-073 configuration) 

This Part tells you how to: 

- Install fuses in the Max Level sensor Wiring on the Fuel Quantity 

Probe of the CWBT.
