The FAA certified the Boeing 737 MAX 7 on 3 August 2026, more than eight years after the smallest MAX variant first flew. Launch customer Southwest Airlines expects first passenger flights in early 2027, while Boeing turns to the MAX 10 and a 737 line cleared to build 47 jets a month.

The US Federal Aviation Administration granted type certification to the Boeing 737 MAX 7 on 3 August 2026, clearing the smallest member of the MAX family for commercial service more than eight years after its March 2018 first flight. Launch customer Southwest Airlines is now preparing for first deliveries, with chief executive Bob Jordan saying the carrier expects its first MAX 7 passenger flights in the first quarter of 2027.
The 737-7 was originally due in service in 2019 but was blocked first by the worldwide MAX grounding, then by a tougher post-crash certification regime, and finally by a flawed engine anti-ice system that Boeing had to redesign. The programme logged roughly 440 certification test flights and nearly 700 flight-test hours, plus about 350 hours of ground testing, according to Boeing. "The certification validates the rigor of your design and recognizes your determination and resilience," Boeing Commercial Airplanes chief executive Stephanie Pope told employees.
The approval also matters for Boeing's wider recovery. Around 30 already-built MAX 7s sit in storage awaiting retrofit and delivery, and the milestone strengthens Boeing's hand in the Airbus–Boeing 2026 delivery race just as 737 output climbs to its highest rate since the January 2024 door-plug accident.
Why did the 737 MAX 7 take eight years to certify?
The 2019–2020 global grounding of the MAX family after two fatal crashes froze all variant approvals. When work resumed, the FAA had stripped back Boeing's delegated self-certification authority, and post-crash reform legislation forced deeper documentation and review of every system.
Then, in 2021, engineers identified a problem with the engine anti-ice (EAI) system shared across the MAX family — the issue that ultimately defined the MAX 7's timeline, according to Air Data News. Finally, the Alaska Airlines MAX 9 door-plug blowout of January 2024 triggered intense political and regulatory scrutiny that killed any prospect of a certification shortcut. For the wider backdrop, see our review of the aviation supply-chain crisis and the world's ageing fleet.
What was the engine anti-ice problem, and how did Boeing fix it?
The EAI system heats the engine inlet to shed ice. On the MAX, regulators found that if crews left it running in dry air, the inlet could overheat — potentially causing engine damage, fuselage penetration and even loss of aircraft control, as the FAA warned in an airworthiness directive cited by FLYING Magazine.
Boeing initially asked the FAA for a time-limited safety exemption so the MAX 7 could be certified before a permanent fix existed. Under mounting pressure after the door-plug accident, Boeing withdrew that request on 30 January 2024 and committed to a full engineering solution. The redesigned system, completed and flight-tested in 2026, eliminates the overheating risk — and testing showed side benefits of lower engine noise and reduced fan flutter, Air Data News reported.
When will Southwest Airlines fly the 737 MAX 7?
Southwest is the type's launch customer and by far its biggest buyer, with 672 firm orders split between the MAX 7 and MAX 8, per Simple Flying; industry-wide, the MAX 7 has accumulated about 282 firm orders, according to Air Data News. The Dallas-based carrier plans to use the jet to replace its ageing 737-700s.
First deliveries follow final production preparations and retrofits of the roughly 30 stored airframes, with revenue flights expected in Q1 2027. Beyond Southwest, Luxembourg's Luxair became the European launch customer with an order for four MAX 7s placed at the 2023 Paris Air Show, ch-aviation reported. The unlock lands just after a mixed Q2 2026 US airline earnings season in which fleet costs loomed large.
What does certification mean for Boeing's 737 production ramp?
The FAA capped 737 output at 38 aircraft per month in January 2024 after the door-plug accident, then approved a step to 42 in October 2025. In May 2026 Boeing passed the regulator's capstone review, clearing the line to rise from 42 to 47 jets a month, chief executive Kelly Ortberg said, and Boeing is targeting 52 a month by early 2027. Certification of the MAX 7 — and the roughly 30 stored airframes it releases — converts that rate into billable deliveries rather than parked inventory.
Next on the docket is the 737 MAX 10, Boeing's answer to the Airbus A321neo and more than a quarter of its remaining MAX backlog. The flight-test campaign is essentially complete and Boeing is targeting MAX 10 certification later in 2026. The MAX family overall has logged more than 7,200 orders, with 2,360 delivered through June 2026, Boeing says — momentum that fed directly into the order flurry we covered at the Farnborough Airshow 2026.
How big is the 737 MAX 7 and how far can it fly?
The MAX 7 is the smallest and longest-range member of the 737 family, aimed at thin, long routes and hot-and-high airports.
| 737 MAX 7 at a glance | Detail |
|---|---|
| Seats (two-class) | 135–160 |
| Range | 3,800 nm (7,040 km) — longest of any 737 |
| Fuel burn / CO2 vs jets replaced | About 20% lower |
| Noise footprint | Roughly 50% smaller |
| Firm orders (type) | About 282 |
| First flight / certification | March 2018 / 3 August 2026 |
Boeing pitches the -7 at about 10% more range than other MAX variants, with the same LEAP-1B engines and common type rating that let operators like Southwest slot it straight into an all-737 fleet. The FAA, for its part, says it will keep inspectors on site at Boeing's factories to monitor production quality even as rates rise.
Frequently asked questions
When was the Boeing 737 MAX 7 certified?
The FAA granted type certification on 3 August 2026, roughly eight years after the variant's first flight in March 2018 and seven years after its originally planned 2019 service entry.
Why was the 737 MAX 7 delayed for so long?
The global MAX grounding of 2019–2020, a stricter post-crash certification regime, and an engine anti-ice system flaw discovered in 2021 all stacked up. Boeing withdrew a requested safety exemption for the anti-ice issue in January 2024 after the Alaska Airlines door-plug accident and completed a full redesign before certification could proceed.
When will Southwest passengers fly on the MAX 7?
Southwest, the launch customer, expects to put the MAX 7 into revenue service in the first quarter of 2027. The jets will progressively replace the airline's oldest 737-700s.
Is the 737 MAX 10 certified yet?
Not yet. Boeing has essentially completed its flight-test campaign and is targeting FAA approval later in 2026. The MAX 10 is Boeing's largest single-aisle jet and its principal rival to the Airbus A321neo.
