Boeing Makes Design Changes: Boeing Commercial Airplanes has made design changes to prevent wiring and plumbing mistakes such as those found on 94 Boeing jets in a recent government-ordered inspection, company officials said. Boeing said it was using different-sized fittings, putting the connections in different locations and using labels and color-coding to prevent the problems found in jetliner engine and cargo hold fire detection and extinguishing systems.
