WASHINGTON, D.C. - After grounding 171 Boeing 737-9 MAX airliners, the Federal Aviation Administration is now investigating Boeing’s manufacturing practices and production lines, including those involving subcontractor Spirit AeroSystems, increasing its oversight of Boeing, and examining potential changes to Boeing's production system.
Last week 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 Boeing 737-9 MAXs 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. The FAA is supporting the National Transportation Safety Board’s investigation into Alaska Airlines Flight 1282. The NTSB is in charge of the investigation and will provide any updates.
