Boeing must replace faulty water couplings on 787s, again

The US aviation regulator is forcing Boeing to replace certain water system couplings on its 787 airplanes. These parts were found to be missing safety straps, which could lead to leaks or other failures.

This rule means Boeing has to fix a known design flaw across a specific fleet of its planes. The original fix was incomplete, so now they have to do it again with a better part. This is a direct cost for Boeing and a safety improvement for airlines and passengers.
