RICHMOND , Va., July 12 /PRNewswire-USNewswire/ -- In his day, BenjaminFranklin understood "critical" supply parts and wrote about the missing horseshoe nail that kept the rider grounded. Exchange "wing fitting" for nailand the same situation occurs with the Air Force's A-10 Thunderbolt II, a versatile aircraft popular with pilots for its effectiveness.
Earlier this year, in response to a fast suspense request from the Air Force for critical A-10 wing fittings, personnel at the Defense Logistics Agency and its Defense Supply Center Richmond , Va., were able to help keep the planes operational.
The A-10's mission is to attack armored vehicles and tanks, as well asprovide close air support of ground forces. The aircraft, nicknamed the"Warthog" for its profile, was first put in service by the Air Force in 1972 and is currently being used to support operations Iraqi and Enduring Freedom.
Earlier this year, the Air Force identified the aircraft wing fitting ofthe A-10 as a critical part. The fitting, which holds the wings on, was inshort supply.
"In early March, we got the request that these parts were needed by June,"said Ann Poythress , airframes division 3 chief, aviation supplier operations,DSCR. "We discovered that we didn't have an awarded contract that couldsupport that time frame."
This critical part is a forging, used wherever strong, durable parts arerequired.
"Forgings are made when metal is heated red hot and hammered in a giant steam hammer, taller than a two-story building," said Daniel Gearing, program manager at DLA's acquisition, technical and supply directorate. "This hammering makes the metal grain flow so it can carry the load without breaking. It's the same as a blacksmith making horseshoes, but on a giantscale, using special alloy steel."
The critical need set off a nationwide search for the steel needed too verhaul the aging aircraft.
"These planes are being flown so hard and so long that they are wearing out," Gearing said. "To keep them going, the Air Force has started overhaul lines at Ogden Air Logistics Center and several other locations."
DSCR plays a critical role in supporting these overhaul lines. "When we can't get parts, the line stops," Gearing said.
In order to manufacture the part, the forge company must first obtain the raw material for the item from the mill. "This unique material is known as maraging steel," said Dean Hutchins , DSCR casting and forging program manager in the Aviation Engineering Directorate.
Maraging steels are low carbon iron-nickel alloys used in components where ultra-high strength is required, along with good dimensional stability during heat treatment. According to Hutchins, mill runs of this type material are only melted by a few plants in the country and the material is relatively expensive and not usually stocked by material suppliers.
"This is why the current delivery time of over 30 weeks is required to obtain this specialty material," he said.
SIFCO Forge Group, the subvendor and the forging facility for the manufacturer ALKEM, was the critical forerunner who helped shorten the leadtime. "Through all of our efforts, SIFCO was able to locate the raw material and have it shipped to them within six days," Poythress said. "It was originally a 38-week lead time to receive the raw material."
Atec, Inc., was honored by the Defense Supply Center Richmond as one of the government's best suppliers at the Automated Best Value System award ceremony.
The company was recognized for its MB4 tow tractor, which met strict quality and delivery requirements established by the Defense Logistics Agency.
The contracts provide replacement parts and maintenance and repair services for the Army, Navy and Air Force. The total includes a five-year, $14.7 million contract.
Eaton's facilities in Costa Mesa, CA, and Irvine, CA, received silver awards for achieving 12-month scores of 99 percent on-time delivery in the DLA's Automated Best Value Supplier evaluation system.
