Boeing must fix faulty water pipe clamps on 787s, again

The US aviation regulator is proposing a new rule that requires Boeing to replace certain water pipe clamps on its 787 Dreamliner airplanes. This means airlines will have to inspect and replace specific clamps that are missing safety straps, or install new, safer clamps.

This is a small, specific fix, but it points to a recurring problem with manufacturing quality control at Boeing. The regulator is stepping in to mandate a design change after an earlier inspection requirement found the problem was more widespread than initially thought. This kind of repeated intervention suggests that Boeing's internal processes are not catching these issues before planes are delivered.
