(Reuters) – The Federal Aviation Administration on Friday proposed fining Boeing (BA.N), opens new tab $3.1 million for a series of safety violations, including actions tied to the January 2024 Alaska Airlines 737 MAX 9 mid-air emergency and for interfering with safety officials’ independence.

The FAA found hundreds of quality system violations at Boeing’s 737 factory in Renton, Washington, and Boeing subcontractor Spirit AeroSystems’ (SPR.N), opens new tab 737 factory in Wichita, Kansas.

The FAA also said Boeing presented two unairworthy aircraft to the FAA for airworthiness certificates and failed to follow its quality system rules.
