Boeing 757s need new crack inspections on old repairs

The US aviation regulator is requiring new inspections for cracks on certain Boeing 757 airplanes. This means airlines must check specific parts of the plane's upper frame, especially where old repairs exist, to prevent structural failure.

Airlines have been flying Boeing 757s for decades, and some of these planes have had repairs that might hide structural problems. This rule means airlines can no longer assume those repairs are good enough. They must now actively look for hidden cracks that could lead to a single point of failure in the plane's frame.
