An Airman from the 92nd Maintenance Group used his innovative ideas to potentially save the KC-135 Stratotanker fleet more than $1 million in parts and man-hours by creating a unique piece of equipment.

Tech Sgt. Shawn Roberge has developed a mechanism to hold the landing-gear doors closed on the nose of the 1950’s era plane, a problem persists with every KC-135.

“The KC-135 has areas prone to damage,” Roberge said. “One of the major areas is where the nose landing doors catch on the outside fuselage skin, tearing it from the current frame design.”

The mechanism could potentially save the Air Force about $1.5 million if Roberge’s invention is used on the entire fleet of 431 Stratotankers that are still in commission.

Roberge created the part with aluminum, keeping it simple, sturdy and durable. The design incorporates three arms that are connected by hinges. Two arms secure it to the underside of the wheel well of the aircraft’s nose, and the third arm hangs down below the doors. When Roberge swings the doors up, a latch on the third arm locks them into place.

Roberge’s design is one fourth the weight of his previous steel design.

When the plane is in flight and preparing to land, two doors open on the bottom of the plane’s nose, and out spring the landing gear and its wheels. But when the plane is being taxied around the air base for repair, the doors must be held shut.

The old technology, which consists of a webbed strap to keep the doors closed, causes the edges of the doors to snag and peel back the sheet metal. Each time it happens, it causes about $3,500 in repair time and material costs.

Roberge’s invention solves the problem.

“The Air Force is empowering our airmen to think outside the box,” Roberge said. “In the past, you couldn’t do that.”
