Boeing grounds dozens of 737 Max Jets
Boeing Co. has grounded dozens of 737 Max jets to repair an electrical flaw that emerged just months after the planes were cleared to return to the skies, forcing airlines to cancel flights and line up replacement aircraft.
U.S. carriers including Southwest Airlines Co., American Airlines Group Inc. and United Airlines Holdings Inc. parked a combined 67 of the workhorse planes Friday, about a third of the Max jets currently in service around the world. The manufacturing glitch affects aircraft at 16 airlines, not the entire Max fleet, Boeing said in a statement.
The U.S. Federal Aviation Administration said the potential lapse “could affect the operation of a backup power control unit,” adding the agency is in “contact with the airlines and the manufacturer and will ensure the issue is addressed.”
While the problem isn’t related to the flight-control system that was at the center of the Max’s nearly two-year grounding, it takes the luster off the comeback of Boeing’s most important product.
The Chicago-based planemaker has been picking up orders for the Max since U.S. regulators lifted a grounding mandate in November and the company recently secured a bumper commitment from Southwest, which had publicly flirted with a smaller single-aisle jet made by Airbus SE.
The issue appears mostly limited to 737 Max planes delivered since the FAA grounding was rescinded.
Boeing fell 1.4% to $251.36 as of 11:17 a.m. in New York, the biggest drop on the Dow Jones Industrial Average. The shares had gained 19% this year through Thursday, double the Dow’s increase.
The newest Max disclosure comes as Boeing contends with quality lapses and manufacturing flaws that have damaged its reputation and affected its 787 Dreamliner, KC-46 military aerial tanker and Starliner spacecraft. The aerospace titan also has fired and sued a subcontractor on another high-profile project: turning two 747 jumbo jets into the next Air Force One fleet to haul U.S. presidents.
The latest issue was discovered by Boeing mechanics “on a production airplane during normal build activity,” according to a message to customers that was reviewed by Bloomberg. Operators were notified just hours after a separate email touting the growing number of flight hours and planes in service since the grounding ended in the U.S.
Boeing declined to say how many aircraft were affected of the 183 Max jets that have been put back into service since December. About 20 operators have been conducting about 400 daily flights, according to a separate memo.
“Boeing has traced the issue to a production change made in the installation process that occurred after our last aircraft was delivered before the fleet grounding in March 2019, which means 24 of our 737 Max aircraft are not affected by this issue,” David Seymour, American’s operations chief, said in a message to employees Friday.
Boeing wouldn’t estimate how much time the repairs will require. “It could take a matter of hours or a few days,” said Jessica Kowal, a Boeing spokeswoman.
