TINKER AIR FORCE BASE, Okla. --  Maintenance crews from the 137th and 507th Air Refueling Wings came together for a crash damaged disabled aircraft recovery (CDDAR) exercise at the Aircraft Battle Damage Repair (ABDR) facility on June 20.

The CDDAR is an annual exercise designed to give members of the crash teams a real world experience by performing an actual aircraft lift while using related equipment.

The scenario for this year's exercise has a KC-135 Stratotanker's nose gear collapse upon landing. The crash crew was notified of the incident and responded.

After being released by the on scene commander, the 507th maintenance team chief determines if the aircraft will have to be airbag lifted from the nose for inspection. The CDDAR team is dispatched along with a KC-135 airframe engineer and jacking subject matter expert as well as the equipment to support the lift.

The team simulates defueling the aircraft and readies it to be lifted. Two aircraft 26-ton airbags are placed at the nose in order to lift and perform the inspection, while four of the same airbags are placed at the tail station to stabilize and prevent the aircraft from sitting on the tail.

Although the base has cranes that would normally be used to lift an aircraft in the event of nose gear failure Master Sgt. Jason Lawson, exercise facilitator of the 507th Maintenance Squadron said, "I think simulation with the aircraft airbags is great training in the event we could not get access to the cranes for any reason."

This year's training was an historic event of sorts. The members of the 137th and 507th did not have access to the ABDR in the past. All simulation for the exercise occurred next to an aircraft or in the hangar.

"We would simulate with just one airbag off to the side," said Lawson. "It's good for the crew to be able to get one of those airbags out and inflated, but it's not nearly the same as lifting the aircraft off the ground."

Master Sgt. Shaun Loeffler, 507th Maintenance Squadron crew chief said getting access to the ABDR facility really added a lot to this year's training.

"We don't typically use the lifting bags," he said. "It was good that we went through the process and the trainer's did a great job of getting everyone involved."

According to Crew Chief Master Sgt. Robert Harding, 137th Maintenance Squadron, Oklahoma Air National Guard, pulling off a training exercise of this magnitude was truly a joint effort and something that the 137th and 507th association will try to build on.

"Even though this is an annual exercise, we tried to give it more realism this year and will try to make it even bigger next year," he said.

He also said this training had more than just 137th and 507th MXS members involved. Crews from the 552nd, 512th and 566th Maintenance Squadrons attended as well as base crane operators, field training detachment instructors, students and other civilians from the base.

"This was hands down the best crash exercise we have done since I became a member of the 507th MXS several years ago," Loeffler said.

Moving forward Lawson said the next CDDAR training will be coordinated with all base team members and will provide a sling lift procedure. They will utilize a crane and put the sling around the belly of the plane and lift it up in order to fold the nose gear up in the wheel well. The team will then carefully sit the aircraft on its nose. They would then assemble a team to pick it up using a crane and/or airbags.

"The point of that would be to get everyone real experience in a controlled training environment." He said.

For now, Lawson said he's very happy they got a chance to work on one of the old model KC-135's and will keep building off that experience in order to get his members the best, real world training possible.
