Pratt & Whitney (a division of United Technologies) and its subcontractor, PCC Airfoils LLC, agreed to pay $52.3 million to the federal government to resolve False Claims Act allegations that they knowingly sold defective turbine blade replacements for engines used in F-15 and F-16 fighter aircraft. According to the Department of Justice, between 1994 and 2003, replacement turbine blades designed by Pratt & Whitney and cast by PCC failed to meet a critical design dimension. Under the settlement, Pratt & Whitney will pay $45.5 million and provide $4.8 million for re-inspecting potentially serviceable blades bought by the Air Force.
