Boeing 787s must fix kinked oxygen lines, and no more bad parts can be installed

The US aviation regulator is ordering inspections and repairs for oxygen supply lines on all Boeing 787 airplanes. This is because the lines can kink when certain passenger service units are installed, which could cut off oxygen.

A kinked oxygen line is a serious safety issue, especially on long-haul flights where the 787 is often used. This order means airlines must now find and fix these problems, ensuring passengers would have oxygen in an emergency. It also stops new planes from being built with the same defect.
