Inspections of grounded Boeing 737 Max 9 jetliners underway
United Airlines said Monday it found loose bolts and other “installation issues” on a part of some Boeing 737 Max 9 jets that were inspected after a mid-flight fuselage blowout on a similar Alaska Airlines jet Friday. The inspections are focused on plugs used to seal an area set aside for extra emergency doors that are not required on United and Alaska Max 9s. That plug is the part that blew off the Alaska plane as it cruised 16,000 feet (4,900 meters) over Oregon.
