Boeing must replace faulty lavatory door latches on 737s

The US aviation regulator proposes a new rule for certain Boeing 737 airplanes. It would require airlines to replace lavatory bifold door latches with an improved design.

This rule comes after a passenger got stuck in a lavatory during a flight. It means airlines will have to spend money to fix a small but critical safety issue. This is a routine safety update, but it highlights how even minor mechanical failures can become serious problems on an airplane.
