See figure 14-25. Nonrepairable Damage Nonrepairable damage exceeds published criteria or limits. Nonrepairable damage may be reclassified as repairable, if cognizant engineering authority prescribes a repair on an individual basis. Normally, nonrepairable damage requires the changing of components. See figure 14-26.
Repairable damage is divided into several classifications.
Information contained in the SRM includes damage classifications, inspection procedures, typical repair procedures, and tool and material lists. Damage exceeding any of these classifications require engineering disposition. Class I Cuts, scratches, pits, erosion or abrasions not exceeding 0.005 inch in depth and 5 inches in length. Class II Damage with dents in the skin up to 3 inches in diameter and 0.01 inch in depth, with no delamination between skin plies, no cracks or graphite fiber breakage, or skin to honeycomb core separation. Class IV Skin damage including delami-nation, cracks, cuts, scratches or skin erosion exceeding 0.015 inch in depth, but less than full penetration, with no damage to honeycomb core.
