I know. But the parts of the plane in the "boneyard" are keep to the current ones flying.
In 2012 AMARG "pulled" more than 10,000 parts, with a value of $472 million. In that year the five fleets calling for the most parts were the Air Force's F-15, B-1B, F-16, C-5, and C-135. The only Navy airplane on the top 10 list, the P-3 Orion, came in sixth.Orders for spare parts are received by AMARG on a Form 44. It documents the requesting base/unit, its priority, whether it supports a combat mission, classification, special handling requirements, acceptable substitutions, and other information.
