Comparison of Air Force and Navy Aircraft Engine Parts Reparability Coding

A survey was undertaken of depot overhaul and repair procedures for aircraft engines and their associated costs. In the survey, GAO noted that some aircraft engine parts, which both the Air Force and the Navy repair, are coded as reparable by the Air Force and nonreparable by the Navy. This is possible since both the Air Force and Navy consider in their coding of engine parts the purchase price, cost to repair, and the number of parts in each inventory.
