The Federal Aviation Administration (FAA) announced on Monday that its inspection of the production of the 737 Max aircraft, conducted at Boeing and its supplier Spirit AeroSystems, found multiple instances where both companies failed to comply with manufacturing quality control requirements. The agency stated that the investigation revealed "noncompliance issues in Boeing's manufacturing process control, parts handling and storage, and product oversight." It mentioned that it has sent a summary of its findings to both companies but has not disclosed them due to the ongoing investigation. Both companies did not immediately comment on the news.
The investigations began following an incident in which a door detached from a Boeing 737 Max 9 mid-flight on January 5. The FAA had previously prohibited Boeing from expanding the production of 737 Max aircraft. Mike Whitaker, the FAA Administrator, stated last week that Boeing must "commit to meaningful and deep improvements." Boeing has rushed to enhance safety measures following the incident that led the FAA to ground Max 9 aircraft for several weeks in January.
