U.S. Air Force Airmen assigned to the Propulsion Flight of the 3rd Maintenance Squadron and the 525th Fighter Generation Squadron remove a Pratt & Whitney F119 engine from an F-22 Raptor at Joint Base Elmendorf-Richardson, Alaska, March 17. When an aircraft is grounded for a long duration, whether due to maintenance, storage, or operational pause: the engine can be vulnerable to internal corrosion, seal degradation, and other forms of wear that are not immediately visible. Re-preservation is a critical process that helps ensure the engine remains within performance and safety standards. Removing the F119 engine from an F-22 is a highly technical process that demands precision, coordination and safety at every stage. (U.S. Air Force video by Airman 1st Class Tala Hunt) More
