AAR wins certification from Pratt & Whitney to overhaul APUs on UH-60 Black Hawk Helicopters

AAR has won an endorsement from Pratt & Whitney to enhance the U.S. Army contract to upgrade and overhaul Auxiliary Power Units (APUs) for its UH-60 Black Hawk helicopters. The new certification augments work being performed at AAR’s Aircraft Component Services facility in Garden City on Long Island as part of a five-year contract, which began in 2014. The original agreement, valued in excess of US$23m, covers work on 60 APUs from the U.S. Army’s Redstone Arsenal in Huntsville, Ala., with a maximum of 520 APUs over the life of the contract. Pratt & Whitney is a world leader in the design, manufacture and service of aircraft engines and auxiliary power units. AAR also upgrades and overhauls the Jet Fuel Starter used on F-16 fighter aircraft. Similar to Jet Fuel Starters, APUs are used on commercial and military aircraft to power the aircraft on the ground and to start the main engines.
