First SLEP Upgrade F-16 Rolled OUT

The Ogden Air Logistics Complex at Hill AFB in Utah has reached a major milestone in extending the life of the USAF’s F-16 fighter fleet. An USAF Thunderbird jet is the first of what will be roughly 300 refurbished C and D model F-16s that will roll off the shop floor of the 573rd Aircraft Maintenance Squadron after receiving multiple structure-strengthening modifications.

The F-16 Service Life Extension Program will keep the jets flying until nearly 2050, thanks to a partnership between the Ogden Air Logistics Complex and the Air Force Lifecycle Management Center’s F-16 Systems Program Office.  The programme combines a dozen structural modifications into one repeatable package – from bulkheads to wings and canopy.  The jets, which became operational in 1979, and were originally deemed air worthy for up to 8,000 flight hours, will have their life extended up to 12,000 flying hours – possibly more, said Capt Randy Nemerson, F-16 SLEP acquisition manager.

All the stateside SLEP modifications will be completed at Hill AFB.  Years of planning and testing have gone into the programme, with AFLCMC, depot and contract engineers having worked together to lay the groundwork, said Nemerson.

The Thunderbird jet was the first of four F-16s that will be used as ‘validation and verification’ aircraft.  Maintainers use the challenges and lessons learned on these first aircraft to better establish the cost, workflow and timeline for the modifications.  “The Thunderbird jet presented some challenges.  This is the largest structural upgrade we’ve ever done,” said Joe Gardenhour, civilian leader in the 573rd AMXS.  “But we’re excited. This programme moves beyond the usual modifications into a standard package of repairs, and it is going to bring stable workload into the depot for years to come.”

As with nearly every major maintenance programme, SLEP is a group effort in the complex.  The maintenance support group is hunting for space for the increased workload.  The entire team is working on hiring, training and certifying a new crop of mechanics and technicians to take on SLEP.

In the commodities maintenance group, where F-16 wings will be refurbished, advanced and automated machinery needs to be purchased and installed along with older, refurbished machines and jigs.  Repairing the wings in-house is a big undertaking, doubling the squadron’s current wing workload, but engineers say it will save millions of dollars.  Schedules between the back shops and aircraft maintenance also need to be closely coordinated so parts and tools are ready at the proper times for tear down and reassembly.

“This is really is a big initiative across the complex, but in commodities we support everyone – F-35, F-22, C-130, A-10s, so there’s always something new and we’re pretty accustomed to taking on the challenge,” said Shane Olsen, leader of the 533rd Commodities Maintenance Squadron.  Once the final processes and workforce are in place, the goal is to complete each SLEP jet in 9 months at a cost of $2.4 million, a small fraction of the cost of buying a new aircraft.  The F-16 Systems Program Office is also working on a separate software and technology upgrade for the type.
