Boeing Commercial Airplanes expects the Federal Aviation Administration to grant final certification for its 737 MAX 10 aircraft soon, in September or October. That would follow the FAA’s expected certification of the 737 MAX 7, which is expected this summer.

The recent details have been reported by Bloomberg News citing individuals close to the certification proceedings. Neither FAA nor Boeing has commented on the possibility.

The 737 MAX 10 is the largest variant of Boeing’s most in-demand jet series. In its Q1 2026 statement, Boeing detailed that the 737 MAX 10 is in the final stage of certification flight testing for new aircraft, FAA’s Type Inspection Authorization 2, which precedes authorization of the aircraft’s conformity and airworthiness inspections.

Reuters reported in June that the FAA’s counterpart the European Air Safety Authority is moving toward 737 MAX 7 and MAX 10 certification on a similar pace.

Both the MAX 7 and MAX 10 have had FAA certification delayed by a series of complications, including the grounding of the 737 MAX program during 2019-2020, tightening of FAA certification standards following the crashes that precipitated that grounding, and intensified FAA oversight of the 737 program following the January 2024 sidedoor panel midflight incident.

A parallel delay has been a technical issue concerning the aircraft’s anti-icing system, after FAA concluded that extended use of the system in dry air could overheat engine inlet components. Boeing redesigned the system to FAA’s satisfaction.

Final certification will be significant for Boeing’s financial outlook, as it will allow the OEM to begin scheduling deliveries of the aircraft, and thereby record its revenue for the sale.

The 737 MAX series is Boeing’s most popular aircraft, and it has close to 5,000 orders in its backlog, for all four variants. The 737 MAX 10 orders represent about 30% of those, with large-volume orders in place from United Airlines, Alaska Airlines, Ryanair, and Delta Airlines.
