As the Pentagon weighs whether to recommend legislation to require more disclosure by contractors, the House Committee on Oversight and Reform will review the audit and TransDigm’s pricing policies in a hearing on Wednesday.

The inspector general’s report “exposes how a company entrusted with supporting our military men and women took advantage of American taxpayers by overcharging the government more than $16 million” in parts sales sold between 2015 and 2017, Oversight Chairman Elijah Cummings said in a statement. The hearing will “investigate whether these pricing issues are more widespread, and demand answers,” he said.

From 2013 through 2015, according to the audit, the contractor increased the price of a valve that opens and closes to change the pressure of fuel moving through an engine to $9,801 from $543. In those years, TransDigm also charged $1,443 each for a “non-vehicular clutch disk” that cost $32 to make.

The Pentagon’s inspector general first raised pricing concerns over TransDigm in a 2006 report, followed by the one this year that was released in redacted form in February.

TransDigm manufactures spare parts for airplanes and helicopters including the AH-64 Apache, C-17 Globemaster III, F-16 Fighting Falcon and the CH-47 Chinook. From April 2012 through January 2017, DOD issued 4,942 contracts valued at $471 million to TransDigm.

Liza Sabol, a spokeswoman for the Cleveland-based company, said in an email “that we are not providing comments on specific questions related to the IG report.”
