An FAA six-week audit released Monday found the Jan. 5 door blowout aboard an airborne Boeing 737-9 MAX was the result of multiple instances where Boeing and partner Spirit Aerosystems allegedly failed to comply with manufacturing quality requirements.
These failures where found in Boeing's manufacturing process control, parts handling and storage and product control.
Boeing last week was given 90 days by FAA Administrator Mike Whitaker to make corrections actions and they must include findings in the new audit as well as findings of an expert review panel that examined concerns with Boeing's safety culture.

On Jan. 24, the FAA halted production expansion of the Boeing 737 MAX and is exploring the use of a third party to conduct independent reviews of quality systems. The FAA is continuing its increased on sight presence at Boeing's production facility in Renton, Washington and at Spirit's facility in Wichita, Kansas.
Boeing last week said it would comply with the FAA and provide a comprehensive quality review ordered within 90 days.
