Table 1. Inspection Requirements (Continued).
Necking
Necking is defined as the decrease in cable diameter at a specific point. Necking is normally
an indication of broken wires and is cause for cable replacement.
Nick
Local break or notch on edge. Usually displacement of metal rather than loss. Nick shall be
blended into surface, or removed if blending proved impossible.
Pitting
Sharp, localized breakdown of metal surface. Usually with defined edges, may result in a
small, deep cavity. Refer to TM 1-1500-344-23 series, Cleaning and Corrosion Control
manual for pitting identification, removal, and surface refinish.
Scoring
Tear or break in metal surface caused by contact under pressure. Deeper than scratch. May
show discoloration from temperature produced by friction. Scoring may be a sign of much
larger problems. Carefully inspect mating and adjacent components for damage. Inspect
area for cause of damage and remedy prior to next operation. Repair minor surface scoring.
Replace component if scoring is extensive, or if component is causing damage to other
parts.
Scratch
Slight tear or break in metal surface caused by light, momentary contact with foreign
material. Scratches shall be blended to remove sharp edges and prevent injury to
personnel. If scratch mars adjacent surface, both components shall be replaced.
