After having 171 Boeing 737 MAX 9 grounded and inspected following the fall of a door in mid-flight, the Federal Aviation Administration (FAA) now indicates that it is investigating “the manufacturing practices” of the American aircraft manufacturer and its subcontractor Spirit AeroSystems.

The FAA made the announcement as part of an update on actions taken since the January 5 incident of Alaska Airlines Flight 1282. Spirit AeroSystems is the supplier that builds and installs the panel that flew into the air.

The organization that regulates and controls the civil aviation in the United States indicates that it wants to examine possible system changes in particular. The investigation will be conducted with the National Transportation Safety Board.

The FAA also indicates that it has completed the first phase of 40 inspections and must now review the data collected.

All 737 MAX 9 aircraft equipped with the same door system will remain grounded pending FAA review and final approval of an inspection and maintenance process that meets all safety requirements.

Once this inspection and maintenance process is approved, each grounded aircraft will need to be assessed before it can be returned to service. Public safety, not speed, will determine the timetable for returning these planes to service, concludes the FAA.

According to several specialists who looking at this model, in particular the head of the specialized site The Air Current, Jon Ostrower, it seems that the MAX 9 has a door that is blocked off and hidden by a partition which only reveals a porthole, which would be at x27;origin of the accident.

For his part, aeronautical specialist Xavier Tytelman believes that this incident could reveal a design flaw in the aircraft rather than a maintenance problem.

Boeing's stock is at its lowest level in two months, having lost nearly 20% since the incident, which however did not cause any casualties.

A Wells Fargo analysis report released Tuesday warned that a Federal Aviation Administration audit would open a whole new can of worms and that Multiple consequences are expected.

Wells Fargo downgraded Boeing's stock in part due to a slowdown in planned 737 MAX deliveries in 2024, which will reduce free cash flow by US$2 billion.
