The efforts are part of a long-term global safety initiative, first reported by Reuters in 2019, to reduce risks such as those faced by the crews in two 737 MAX crashes. Missing the deadline could require Boeing to revamp the jet's crew alerting system and mean separate pilot training - raising costs to airlines and putting orders at risk.ĭelaney's comments came during a media event where Boeing unveiled new pilot training tools and a revamped data-sharing system. The deadline for changes was introduced as part of broader regulatory reforms at the Federal Aviation Administration after fatal 737 MAX crashes in 20. planemaker is facing an increasingly high-stakes battle to win certification for the largest variant of the 737 MAX before a new safety standard on cockpit alerts takes effect.

The manufacturing change that led to the original problem was considered so minor that it didn’t require an FAA approval or a review by Boeing employees deputized as agency representatives, the regulator said.The embattled U.S. In some instances, coating such as paint may affect the electrical grounding path, causing a unit that controls backup power for the aircraft to malfunction, the people said. “The FAA will thoroughly review any proposed fix that Boeing presents to us,” the agency said in an emailed statement.Īviation Week reported earlier that the flaws were traced to a manufacturing change made in early 2019 that involves fasteners and a coating. The FAA hasn’t mandated any repairs yet while Boeing continues to assess the situation. The shares fell 1.2% to $248.18 at the close in New York.

The bulletins focus on ensuring a sufficient ground path in the flight deck of affected airplanes.” Federal Aviation Administration have an action plan, said one of the people, who asked not to be identified as the matter is confidential.īoeing said it “is working with customers on service bulletins that will be submitted to the FAA for approval. The work should take a few days for each airplane once Boeing and the U.S. 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. 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 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.

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. Boeing 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.
