Japan’s All Nippon Airways Co. (ANA) has found another problem on the 787 Dreamliner from Boeing Co. (BA). On Wednesday, a flight from Tokyo to Frankfurt was delayed due to faulty wiring in a fire suppression system for one of the plane’s engines.
According to reports, the system may activate a fire extinguisher on the wrong engine in the event of a fire on one of the 787’s two engines.
Boeing’s solution is to ask airlines to check their own 787s using an instruction sheet the aircraft maker will supply. A company spokesman told Bloomberg News that the inspections will take only a few minutes and the problem “doesn’t present an immediate flight-safety issue” because there are “multiple redundancies with the fire extinguishing system.”
Boeing is blaming the problem on the supplier, Kidde, a division of United Technologies Inc. (UTX), which said it is working to resolve the issue.
ANA inspected all 20 of its 787 Dreamliners and found three with the faulty fire-suppression system. So far no other airlines have said that they have found the same problem.
Boeing’s shares are inactive in premarket trading, having closed on Thursday at $102.73 in a 52-week range of $69.03 to $109.49.
