FAA increases oversight of Boeing 737 Max 9 jets following near-disaster Alaska Airlines incident

The Federal Aviation Administration will start conducting more oversight of Boeing 737 Max 9 jets, following problems with its fuselage.

"The FAA is increasing its oversight of Boeing’s production lines and suppliers, and limiting certain approvals until we are satisfied that the quality control issues uncovered during this process are resolved," the agency announced Monday, according to NBC News.

This announcement comes after the administration opened up a probe into Boeing after a door plug on one of its commercial jets used by Alaska Airlines recently detached mid-flight, leaving a gaping hole in the fuselage. 

This resulted in the FAA grounding about 171 out of 218 Boeing 737 Max 9 airplanes after it was revealed the plane that had the door fly off had loose bolts. 

More recently a supplier spotted some problems with holes incorrectly drilled in the window frames of some Max jets. 

FAA Deputy Associate Administrator for Aviation Safety Jodi Baker said that the agency has already inspected multiple Alaska and United Airlines jets and that 135 of them have returned to service, NBC News reports. 

The oversight process is expected to take six weeks, according to Yahoo Finance.
