Boeing Co. has found potential electrical flaws in two additional areas of the 737 Max’s cockpit, a week after a similar manufacturing defect prompted a temporary flying halt for recently delivered jetliners, said people familiar with the matter.
The planemaker has inspected the Max’s flight deck for other electrical faults near the flaw revealed last week with the plane’s standby power-control unit, and is crafting plans for repairs. The maintenance isn’t expected to be time-consuming or complicated, requiring only basic hardware such as nuts and bolts, according to a Max customer briefed by Boeing.
Still, the discovery of new problems adds to the embarrassment for Boeing, which is trying to engineer a smooth return for the Max after a 20-month grounding forced by two deadly crashes. The electrical issue potentially affects about 450 Max jets manufactured since early 2019, including about 90 aircraft operated by airlines with the rest still awaiting delivery.
