US aviation regulators plan to require Boeing to rewire all 737 MAX aircraft before allowing the troubled planes fly again, the Wall Street Journal has reported. The MAX has been grounded worldwide since an Ethiopian Airlines flight crashed shortly after take-off last March, less than six months after the same model was involved in a similar fatal accident in Indonesia. Regulators have since concluded that the current wiring layout violated safety standards to prevent short-circuits that could cause similar sharp drops in aircraft pitch, the newspaper said Sunday.
