Boeing: Possible wing defect unlikely to delay return of Max

A possibly defective part in the wings of Boeing 737 Max jets can be quickly fixed and is unlikely to delay return of the airliner to commercial service, officials said on Monday.

Boeing told the US Federal Aviation Administration, or FAA, that leading-edge slat tracks on some 737 Max and NG jets may have been improperly manufactured by a subcontractor and therefore may not meet regulatory requirements for strength and durability.

"Although a complete failure of a leading-edge slat track would not result in a loss of the aircraft, a risk remains that a failed part could lead to aircraft damage in flight," the FAA said in a statement released on Sunday. "The FAA will mandate Boeing's service actions to identify and remove the discrepant parts from service within 10 days."
