Engines: managing the maintenance
Staff Sgt. Joshua Crane, 2nd Maintenance Squadron assistant engine manager, goes through engine jacket files on Barksdale Air Force Base, La., Aug. 22. The files are used to keep track of the maintenance and inspection history of each engine. Once an engine has accumulated 6,000 hours of operation, the engine is shipped to the Maintenance Depot at Tinker AFB, Okla. (U.S. Air Force photo/Airman 1st Class Micaiah Anthony)(RELEASED)
