Depot Inspection and Repair Capability
Unique or Redundant?
This report presents the results of a study to determine if inspection and repairs undertaken at the depot could be done at the base. Six F-4 aircraft were followed through depot inspections, and the 1932 defects discovered were rated by depot personnel in terms of where, base or depot, each defect could have been discovered and repaired, its effect on the aircraft, and related issues. A subsample of 177 of these defects was also judged by base maintenance personnel. Both base and depot judges estimated that almost all defects in the sample could have been discovered and repaired at base level without additional equipment. Although normal mission wear causes most defects, faulty maintenance accounts for a large percentage. Study results clearly indicate that inspection and repair of defects discovered in depot IRANs could be accomplished at base level with rare exception.
