The New York Times reports Boeing has discovered yet another massive flaw with its troubled 737 MAX jets. A December audit of the plane’s safety, ordered by the Federal Aviation Administration, or the FAA, found previously unreported concerns with the wiring in 737 MAX airplanes, which could potentially cause a short circuit and a crash if pilots did not respond adequately. Last month, Boeing CEO Dennis Muilenburg was fired just weeks after the corporation halted production of the jet, following outrage over two crashes in Ethiopia and Indonesia that killed all 346 people on board.
