Bolts appeared to be missing on the plane when it left Boeing's factory, a preliminary investigation found.

United was contracted to receive 43 Boeing 737 Max 8 and 34 Max 9 models this year, but expects to get 37 and 19 of them, respectively, according to a company filing. It also had contracted deliveries of 80 Max 10s in 2024, the largest model in the bestselling Max family, but expects none of them this year. The plane hasn't yet been certified yet by the Federal Aviation Administration and is years behind schedule.

United's CEO, Scott Kirby, in January said the carrier is making a fleet plan without the Max 10.

"As you know, United has hundreds of new planes on order and while we remain on a path to be the fastest growing airline in the industry, we just won't grow as fast as we thought we would in 2024 due to
