The FAA’s production audit into Boeing and supplier Spirit AeroSystems has found multiple instances where the companies allegedly failed to comply with manufacturing quality control requirements.

The FAA’s decision comes after a thorough review revealed concerns about the manufacturing process, raising alarms over the safety and reliability of the aircraft.

Boeing, a major player in the aerospace industry, now faces a setback as the FAA has ordered a temporary halt to the production of the 737 MAX until the identified quality control issues are addressed and rectified.
