Proposing a redistribution of F-4 inspections to (1) reduce inspection workload at base by 75 percent without decreasing compliance with the applicable Technical Order, (2) increase routine and emergency aircraft availability, (3) increase reliability, (4) reduce maintenance workload for deployed units, and (5) help in more efficient scheduling. Under the present phased inspection system for the F-4, 70 percent or 80 percent of the scheduled intermediate level inspection workload at base is repeated at the Air Materiel Area during Programmed Depot Maintenance (PDM--formerly called Mod/IRAN). PDM is done on a calendar time basis and phased inspections on a flying-hour basis, with no coordination between them. Each phased inspection at base keeps the plane unavailable an average of 6.6 days. Aircraft have more aborts and need more maintenance following any such inspection, however small. By eliminating duplication, Quick Fix cuts base inspection dock visits 75 percent and consequently improves reliability, as well as availability. Appended calculations by John DeOlden show $1 million yearly saving in CONUS direct maintenance personnel alone.
