US aviation regulators warned Boeing Co. that its 737 Max 7 model is at risk of missing a key deadline later this year, potentially forcing the planemaker to carry out an expensive and complex redesign of the aircraft.

The Federal Aviation Administration’s chief of aircraft certification told Boeing in a Sept. 19 letter that the agency had approved less than 10% of the required safety assessments submitted by the company for the Max 7. Another 70% of the documents are in “various stages of review and revision,” according to the letter, which was viewed by Bloomberg.
