Boeing 737 Max 9 Grounded After Fuselage Incident

Loose bolts on door plugs found in other 737 Max 9's, prompting FAA to require immediate safety inspections.

A piece of fuselage known as a door plug fell from the Boeing 737 Max 9 plane operating Alaska Airlines flight 1282 as it climbed out of Portland International Airport.
Two of the largest Max 9 operators — Alaska and United Airlines — have since said they found loose bolts on door plugs of other 737 Max 9's in their fleet.
The Federal Aviation Administration (FAA) grounded approximately 171 of the Boeing 737 Max 9 aircraft operating worldwide, requiring immediate and enhanced safety inspections.
Boeing's CEO, Dave Calhoun, held an all-hands safety meeting with staff, acknowledging the company's mistake and promising full cooperation with the FAA and the NTSB investigations.
United and Alaska Airlines, both operators of the 737 Max 9, have had to cancel hundreds of flights due to the grounding.
