757 MAINTENANCE MANUAL
 FUEL TANKS - APPROVED REPAIRS
_____________________________
 1.  General_______
 A.  This procedure contains eight tasks. The tasks are:
 (1)  
Make an analysis of the fuel leak type and the usual repair procedure

 (2)  
Make an analysis of the causes of the fuel leaks

 (3)  
Repair of sealant leaks in the fuel tank structure

 (4)  
Repair of fuel tank corrosion

 (5)  
Examination and closure of repaired fuel tanks

 (6)  
Fueling of repaired fuel tanks

 (7)  
Approved repairs of nonsealant leaks

 (8)  
Approved repairs of the secondary fuel barrier sealant.

 B.  
These procedures contain information on how to prepare, use and cure the sealant and finish materials, and apply the corrosion resistant finishes in the fuel tank. The sealant and recommended finish materials shown for use in this procedure can be used with each other. For example, you can use fully cured corrosion resistant finish as a topcoat that you can apply with a spray gun or brush over the sealant. If the surface has a finish layer (topcoat), remove all of the finish from the sealant repair area. This is not necessary if the finish is heat-cured (baked-on) BMS 10-20 Type II finish material (as it is applied to a new airplane in the factory).
