E. Inspection/Check - Fuel Storage System
A wet or stained spot on the wing can be an indication of a fuel leak. Not all fuel leaks require immedi-
ate repair. Fuel leaks which do not constitute a flight hazard can be repaired at the next scheduled ser-
vicing. Fuel leaks that do not constitute a flight hazard are stains, seeps, and heavy seeps which are
not in an enclosed area. Fuel tanks are sealed with MIL-S-8802 Type ll sealant.
Repairs that break the fuel tank access panel seal will necessitate resealing of that fuel tank. All
repairs made within the fuel tank must be fay surface sealed and fillet sealed. All boundaries and any
other place that could leak must be sealed. Stains and seeps which are not immediately repaired must
be inspected prior to and immediately after each flight until they have been repaired.
(1) Stain
(a) Stains are 3/4 of an inch in size or less.
(2) Seep
(a) Seeps range in size from 3/4 of an inch up to 1 1/2 inches.
(3) Heavy seep
