Boeing must replace incorrectly made parts on some 787s

The US aviation regulator is ordering Boeing to replace certain floor beam fittings on some 787-9 and 787-10 airplanes. These parts were made with the wrong material, which could make the planes unsafe.

This is a routine safety order, but it points to ongoing manufacturing quality control issues at Boeing. The company has faced increased scrutiny over its production processes, leading to multiple investigations and grounded planes. This order means Boeing must spend money and time to fix these specific planes.
