Boeing Co said on Sunday it will have to do more work on about 50 undelivered 737 MAX airplanes, potentially delaying some near-term deliveries, after its supplier Spirit AeroSystems discovered two mis-drilled holes on some fuselages.
Boeing confirmed the findings in response to a Reuters query after industry sources said an “edge margin”, or spacing problem, had been found in holes drilled on a window frame on some jets.
Boeing, which has been under fire from regulators and airlines since the Jan. 5 blowout of a door plug on a 737 MAX 9, said safety was unaffected and existing 737s could keep flying.
