The Federal Aviation Administration announced Wednesday that it is investigating Boeing’s manufacturing practices and production lines.
It includes processes involving Spirit AeroSystems, the Kansas-based company that builds the fuselages and other parts of Boeing planes.
The FAA said its investigation is also “examining potential system change.”
All 171 Boeing 737 Max 9 jets with a door plug have been grounded by the agency following the Alaska Airlines Flight 1282 incident.
“The safety of the flying public, not speed, will determine the timeline for returning these aircraft to service,” the FAA added.
