2. Inspection of the Electrical Bonding Jumpers in the Fuel System_______________________________________________________________
A. General
(1)
This task contains visual, mechanical and physical inspections of the electrical bonding jumpers in the fuel system.
(2)
The tin plating on the bonding jumper usually supplies a smooth finish. When there is deterioration of the tin plating on the bonding jumper and the copper in the wire reacts with any sulfur compounds in the tank, the finish becomes rough to the touch and the bonding jumper can show signs of fraying.
