Dozens of 737 Max jets due to Boeing-based errors | Aviation News

U.S. carriers, including Southwest Airlines Co, American Airlines Group Inc. and United Airlines Holdings Inc., parked a combined Ked 67 on a workhorse plane on Friday, currently holding about one-third of the world’s maximum Max aircraft.

Boeing Co. was able to repair an electrical fault to several thousand 777 Max jets that forced the airline to cancel flights and line up replacement aircraft just months after the planes were cleared to return to the skies.

Southwest Airlines Co., American Airlines Group Inc. And the U.S. Air Force, including United Airlines Holdings Inc., parked one-third of the world’s largest Max Jet employee aircraft on Friday. Boeing said in a statement that production boundaries affect aircraft at 16 airlines, not the entire Max fleet.

The U.S. Federal Aviation Administration said the potential crash could “affect the operation of the backup power control unit,” adding that the agency had “contacted the airline and the manufacturer and would confirm the matter.”

While the problem isn’t related to the flight-control system that was at the center of Max’s nearly two-year grounding, it will take illumination from the return of Boeing’s most important product. The Chicago-based aircraft maker has been receiving orders for the maximum since U.S. regulators revoked the grounding mandate in November, and the company recently received bumper commitments from the Southwest, which was publicly revealed with a small single-easel jet made by Airbus SE.

One analyst said the matter is mostly confined to the 7337 Max plane that FAA grounding was withdrawn. “The timing is well understood and the timing will depend on the availability of access to technicians and equipment,” Jefferies analyst Sheila Kahayoglu wrote in a research note to clients. “Changing equipment can take hours or days to be corrected, a moderate exception.”

The biggest drop in the Dow Jones Industrial Average was at 11:11 a.m. in Boeing New York, and 11.1 a.m. in New York. It fell 1.4% to 251.36. Shares rose 19% this year through Thursday, doubling Dow’s growth.

Boeing opposes the fight against quality laps and production defects that have damaged its reputation and damaged its 7৮7 Dreamliner, KC-46 military military aircraft tanker and Starliner spacecraft. Aerospace’s Titan has fired and sued a subcontractor in another high-profile project: turning two 744bo jumbo jets into two Air Force One fleets to take action against US presidents.

The latest problem was discovered by Boeing mechanics “on top of a production aircraft during normal construction,” according to a message addressed to customers reviewed by Bloomberg. Operators were notified of the growing number of flights and the growing number of planes in services after grounding in the United States a few hours after the separate email.

The Boeing 183 Max aircraft, which has been put back into service since December, declined to say how many planes were hit. According to a separate memo, about 20 operators are operating about 400 flights a day.

“The Boeing issue discovered that our last aircraft was delivered before the fleet was grounded in March 2019. Our last aircraft came after delivery, which means that 24 of our 737 Max aircraft are not affected by this problem,” said David Seymour, Chief of American Operations. , In a message addressed to staff on Friday.

Can’t estimate how long it will take to repair the Boeing. “It could take hours or even days,” said Jessica Coyle, a Boeing spokeswoman.

Airline effect

Southwest said it had flown a maximum of 30 jets since the scheduled time, adding that it had flown only 15 of its 57 Max aircraft per day and expected “minimal” disruptions to its operations. The Dallas-based carrier said it did not experience any operational problems related to electrical problems identified by Boeing.

American 17 Max planes were removed from service while United shut down 16 planes, and Alaska stopped four flights each.

The 7337 Max, the latest generation of Boeing’s single-isle workhorse, landed in Indonesia and Ethiopia in 2011 and 2019 after two accidents five months apart, killing 346 people.

In November, U.S. regulators cleared the plane to fly again, followed by regulators in other major markets, excluding Europe and China and India.
