U.S. Airmen from the 20th Component Maintenance Squadron gather at a test cell facility at Shaw Air Force Base, S.C., March 3, 2017. Airmen at the facility are responsible for testing F-16CM Fighting Falcon engines to ensure they function safely. (U.S. Air Force photo by Airman 1st Class Kathryn R.C. Reaves)

An F-16CM Fighting Falcon engine rests on a stand at a test cell facility at Shaw Air Force Base, S.C., March 3, 2017. The facility is responsible for troubleshooting approximately 30 engines per year, which is done by running the engine in a controlled environment.

U.S. Air Force Staff Sgt. Dale Rodgers, 20th Component Maintenance Squadron aerospace propulsion craftsman, holds the throttle for an F-16CM Fighting Falcon engine at a test cell facility at Shaw Air Force Base, S.C., March 3, 2017. The throttle controls the engine being tested and can quickly shut the engine down in case of an emergency. (U.S. Air Force photo by Airman 1st Class Kathryn R.C. Reaves)

An F-16CM Fighting Falcon engine runs at a test cell facility at Shaw Air Force Base, S.C., March 3, 2017. At about 15 feet in length, the F110-GE-129 turbofan engine produces approximately 29,000 pounds of thrust. (U.S. Air Force photo by Airman 1st Class Kathryn R.C. Reaves)

After running an F-16CM Fighting Falcon engine, an inspection is performed to check for leaks and damage. (U.S. Air Force photo by Airman 1st Class Kathryn R.C. Reaves)

U.S. Air Force Senior Airman Jarrod Adams, 20th Component Maintenance Squadron aerospace propulsion journeyman, checks a magnetic chip detector (MCD) at a test cell facility at Shaw Air Force Base, S.C., March 3, 2017. While an F-16CM Fighting Falcon engine is tested, the MCD attracts metal shavings from bearings in the engine. Because each bearing is made of a different type of metal, nondestructive inspection Airmen can pinpoint which bearing is failing and needs replacement.
