>>2044677Fuel contamination is unlikely to strike both engines at the same exact time. Based on what the whistleblowers were saying, it's possible metal shavings were left next to the wiring insulation and wore it down over time as the aircraft flexes, causing total electrical failure. But we have to wait for the report to find out.
"The next incident occurred in 2019 when,as The New YorkTimesreportedin an exposé at the time, John Barnett, a former quality manager who retired in 2017, revealed that he had filed a whistleblower complaint, alleging sloppy work around the wires that connect the planes’ flight control systems, with metal shavings being left behind when bolts were fastened. The risk existed that the shavings would penetrate the wires’ insulation, leading to consequences that Barnett called “catastrophic.”
Barnett also alleged that damaged or substandard parts were being installed in 787s, including a dented hydraulic tube that a senior manager retrieved from a bin of what was supposed to contain scrap. The FAA inspected several 787s that were said to be free of the shavings Barnett reported and found that they were indeed there, reported theTimes. The FAA then ordered that Boeing correct the problems before the planes were delivered to customers."
