TM 55-1680-320-23 & P2-11. RESCUE HOIST - INSPECT (cont)2-115.6.Inspect electrical components for corrosion and damage.Check for evidence of overheating and shorting, Inspect electrical wiring for frayed and broken insulation.Check for cuts and tears. Inspect electrical connectors for bent,broken and missing pins.Inspect identification and lubrication plates for legibility and security of attachment.Table 2-3. INSPECTION REQUIREMENTSNOTEMinor component defects (small scratches, minor dents, etc.) are acceptable in some cases, providing thedefect does not effect t& performance of the component. It is up to the user to determine whether a defectis acceptable, whether minor repair can return the component to use, or whether the component should bediscarded and replaced.Burr -A small, thin section of metal extending beyond a regular surface,usually located at the comer or edge of a bore or hole. Burr shall beremoved to prevent injury to personnel and damage to adjacent components,and resulting scratch or score shall be repaired,Corrosion -Loss of metal from a surface by chemical or electrochemicalaction. Corrosion products are usually easily removed by mechnicalmeans. Refer to Avionic Cleaning and Corrosion Prevention manual forcorrosion identification, removal, and surface refinish.crack -A physical separation of two adjacent portions of metal, evidenced bya fine or thin line that crosses surface. Caused by excessive stress, itmay extend inward from surface a few thousandths of an inch, or runcompletely t.hrough section thickness. Cracks pose a serious threat tocomponent operation and may cause injury to operator. Cracks must berepaired immediately. Extensively cracked surfaces shall result incomponent replacement.Dent -Indentation in metal surface produced by an object striking withforce. The surface surrounding the indentation will usually be slightlyupset. Dents may be removed providing the repair does not structurallyweaken component. Minor dents may be left in surface if they do not rubagainst or contact adjacent parts.Nick -Local break or notch on edge. Usually displacement of metal ratherthan loss. Nick shall be blended into surface, or removed if blendingproves impossible.Pitting -Sharp, localized breakdown of metal surface. Usually with definededges, may result in a small, deep cavity, Refer to Avionic Cleaning andCorrosion Prevention manual for pitting identification, removal, andsurface refinish.GO TO NEXT PAGE2-40
