The FAA is now investigating Boeing’s manufacturing practices and production lines, including those involving subcontractor Spirit AeroSystems, bolstering its oversight of Boeing, and examining potential system change.
On Friday, the FAA announced requirements for a rigorous inspection and maintenance process as a new and necessary step before the FAA contemplates any further steps in the process to return the Boeing 737-9 MAX to service.
The first 40 inspections that are part of that process are now complete, and the FAA will thoroughly review the data from them.
All 737-9 MAX aircraft with door plugs will remain grounded pending the FAA’s review and final approval of an inspection and maintenance process that satisfies all FAA safety requirements.
Once the FAA approves an inspection and maintenance process, it will be required on every grounded 737-9 MAX prior to future operation.
