6-5. GENERAL

Inspect wiring for cut, burned, or abraded insula-

tion exposing bare connector; abrupt V bends

which weaken conductor; points or abrasion not

insulated; pinched or damaged wires; broken or

Inspect the internal connectors for broken, loose,

loose lacing; loose clamps.

bent, corroded, or missing pins; cracked insulation.

Inspect printed circuit cards for broken, cracked,

b. Inspect hardware for missing screws, nuts, bolts,

or burned parts, broken circuitry, chipped con-

rivets and Iockwashers; screws, nuts, or bolts with

tacts, copper showing on contacts or circuitry;

stripped threads,

cracks, holes or burns in cards, defective solder

Inspect for missing, incorrect, illegible, or oblit-

joints; cracks, bubbles or holes, lifted pads, broken

erated markings, decals, or reference designators.

or missing eyelets, loose or dangling wires, bent or

d. Inspect solder connections for no solder, cold or

shorted wire wrap pins,

crystallized joints.
