The Pentagon inspector general has subpoenaed Pratt & Whitney after an audit revealed that the Air Force was at risk of overpaying for work on engines for C-17 planes, Bloomberg News reports.
The East Hartford-based company is accused of refusing to provide documentation for more than $1.54 billion worth of maintenance done on the engines, according to Bloomberg News.
A spokesperson for the company said Pratt & Whitney has been selling F117 engines to the Air Force since the early 1990s and has been providing repair service on the engines for 25 years.
"We believe Pratt & Whitney has provided the Air Force sufficient data to declare commerciality and determine price reasonableness for F117 engine fleet management sustainment services," Pratt & Whitney spokesperson Matthew Bates said in a statement Tuesday. "P&W investment in the F117 engine and the F117 PBL has saved the USAF significant Operations & Maintenance costs while successfully achieving safe operation and readiness targets."
Bates said the engine has saved the Air Force 1,000 shop visits and $3 billion in repair costs.
"We look forward to reviewing the findings of the DoD IG report and working with our customer to ensure we meet the highest standards of affordable readiness for the C-17 fleet," Bates said.
F117 engines power C-17 aircrafts and is derived from the PW2000, which powers the commercial Boeing 757, according to Bates.
