Boeing expects to complete certification of its smallest variant of the B737 MAX family, the B737-7, and begin deliveries of the aircraft this year. However, the larger variant of the model, the B737-10, will not be delivered before 2023, two years behind the original schedule.

“This schedule reflects several factors, including an updated assessment of global certification requirements informed by ongoing discussions with regulators and resulting in management’s decision to make modifications to the aircraft design,” the manufacturer said in its annual report.
With recertification of the B737-8 and B737-9 completed, Boeing has moved on to certifying the variants that have yet to obtain regulatory approval.

The B737-7 made its first flight in March 2018. It was close to certification when the family was grounded worldwide. Boeing currently has 79 firm orders, including four B737-7 BBJs, with Southwest Airlines as the largest customer with 30 aircraft.
The B737-10, meanwhile, was announced in 2017 and was originally due to begin delivery in 2021. Boeing has firm orders for 467 B737-10s, including 128 from United Airlines and 106 from VietJetAir.
The third B737 MAX variant not yet certified is the B737-8-200, a modified high-density B737-8 intended for the low-cost segment. It is in the final stages of certification and is scheduled for initial delivery to Ryanair Holdings this quarter.
