A version of the JT3D turbofan engine designated TF33 by the U.S. Air Force, the majority of these engines built are still flying today.  Among others, the TF33 engine powers the B-52 Stratofortress, a mainstay of the USAF heavy bomber fleet.  FSI holds repair approvals for numerous TF33 components, resulting in a significant reduction in aircraft time out of service, and savings of millions of dollars over replacement part costs.
   

The F100 series of engines are powering a wide selection of aircraft, on behalf of numerous countries. The USAF employs these engines in aircraft such as the F-15 Eagle and the F-16 Fighting Falcon. Flight Support continues to gain approval from the USAF on the F100, successfully bringing its innovative approach to necessary repairs.

An axial-flow turbojet developing up to 11,200 pounds of thrust, these engines powered U.S. Navy jets for decades.  Flight Support repair of various components in J52 engines ensured that cost-effective steps have been available to keep these legacy engines aloft.
