The Federal Aviation Administration issued $3.1 million in proposed fines against The Boeing Company for safety violations in factories, including the Renton factory as a violator.

The safety violations in question occurred between Sept. 2023 and Feb. 2024, and include actions related to the Jan. 5, 2024, door plug blowout, and interference with safety officials’ independence, the FAA said.

The FAA identified hundreds of quality system violations at Boeing’s 737 factory in Renton and Boeing subcontractor Spirit AeroSystems’ 737 factory in Wichita, Kansas. They said two of Boeing’s aircraft failed the “airworthiness certificate” test when presented for testing and the company failed to follow its quality system.

The FAA also reported that a non-Organization Designation Authorization (ODA) Boeing employee pressured a Boeing ODA unit member to sign off on a Boeing 737-MAX airplane to meet a delivery schedule after the ODA member determined the aircraft did not comply with standards.

The FAA said utilizing the maximum statutory civil penalty authority is consistent with the law with the $3,139,319 fine, and Boeing has 30 days to respond to the agency after receiving the FAA’s penalty letters.

Boeing’s 737 factory has 1.1 million square feet in factory space and has rolled out more than 10,600 737 jets since the program began in 1967, according to Boeing. The facility employs approximately 12,000 people at the Renton location.
