Britain's Sky News network quoted former auditors Taylor Smith and Jeannine Prewitt as saying Boeing accepted defective parts for 737s and other jets from Ducommun, a Carson, Calif., supplier, and installed them even though they knew they were faulty and potentially dangerous.
The components allegedly had incorrectly drilled holes and other physical defects that made them more likely to fail, Sky News reported.
The allegations involve the 737NG models built between 1994 and 2002, the report said.
While officials with Ducommun did not respond to questions from the network, a Boeing statement said the allegations were "without merit" and claimed its multi-tiered control process has been effective in maintaining quality and safety.
