This is the best summary I could come up with:

Bolts in need of "additional tightening" have been found during inspections of Boeing 737 Max 9s, United Airlines has said.

Inspections began after a section of the fuselage fell from an Alaska Airlines 737 Max 9 on Friday.

United Airlines said "installation issues" relating to door plugs would be "remedied" before the aircraft type would return to service.

In its statement, United said: "Since we began preliminary inspections on Saturday, we have found instances that appear to relate to installation issues in the door plug - for example, bolts that needed additional tightening."

The door plug is a piece of fuselage with a window that can be used as an emergency exit in certain configurations.

It was this part of the Alaska Airlines plane which dramatically fell off mid-flight over the US state of Oregon, eventually landing in a teacher's back garden.
