The last of 247 US Air Force’s 5th-generation F-22 Raptors recently completed the structural repair program that has been generating aircraft for the last 14 years.

The F-22 System Program Office worked with Lockheed Martin and Boeing to perform structural modifications to increase total flying hour serviceability on each aircraft by 8,000 hours.

“This is a great milestone for the program,” said Misty Stone, 574th AMXS director. “Since Hill Air Force Base gained the F-22 workload in 2006, the 574th AMXS team of 400 employees has remained focused and dedicated on expanding the combat capabilities of the F-22 weapon system,”

The maintenance team processed 247 F-22 Raptors through six unique maintenance machines for structural repair, modification, coatings restoration and aircraft damage repair.

With the program completed, the 574th AMXS will shift from a workload that was a structural based requirement to a 10-year reversion workload, which is a new sustainment modification that was first prototyped in 2019.

This new modification will refurbish the low observable coatings on the engine inlets, and provide an inspection and overhaul of the aircraft’s flight controls.

Over the past several years, the aircraft maintenance squadron has also supported the warfighter by overhauling five aircraft that had been damaged through the unscheduled depot level maintenance program totaling 50,900 hours.

“We have already ramped up our new reversion workload producing nine aircraft totaling nearly 200,000 hours to date. In conjunction with this workload, we are currently posturing ourselves to accomplish avionics upgrades that will greatly improve the already amazing capabilities of the F-22,” said Paul Woolever, 574th Production/Flight Test section chief. “The success of the 574th AMXS ability to produce modifications, repairs, and upgrades to the Raptor is a direct result of the amazing team of skilled mechanics, dedicated supervisors, and the expert knowledge of the planning and scheduling department that we have.”
