EAKAGE DEFINITIONS FOR ORGANIZATIONAL PMCS

TM 10-3990-203-13&P

(a) Keep it clean: Dirt, grease, oil and debris only get in the way

and may cover up a serious problem. Clean as you work and as needed. Use

dry cleaning solvent (P-D-680) to clean metal surfaces. Use soap and water

when you clean rubber or plastic material.

(b) Bolts, nuts and screws: Check that they are not loose, missing,

bent or broken. You can't try them all with a tool, of course, but look for

chipped paint, bare metal or rust around bolt heads. Tighten any bolts,

nuts, and screws that you find loose.

(c) Welds: Look for loose or chipped paint, rust or gaps where parts

are welded together. If you find a bad weld, report it to direct support.

(d) Hoses and fluid lines: Look for wear, damage and leaks. Make sure

clamps and fittings are tight. Wet spots show leaks, of course, but a stain

around a fitting or connector can mean a leak. If a leak comes from a loose

fitting or connector, tighten it. If something is broken or worn out, either

correct it or report it to direct support (refer to MAC Chart).

5. It is necessary for you to know how fluid leaks affect the status of your

equipment. The following are definitions of the types/classes of leakage you

need to know to be able to determine the status of your equipment. Learn

and be familiar with them and REMEMBER -- when in doubt, notify your supervisor.
