Boeing is managing two certification clocks simultaneously in 2026. One is running on schedule. The other is running out of runway. 777-9: April Is the Moment Boeing announced in February that the first flight of a production-standard 777-9 — specifically the Lufthansa-destined aircraft — was planned for April 2026. That window is now open. The Lufthansa airframe has completed fuel and engine tests at Paine Field in Everett. A first flight this month would be the single most important 777-9 program signal since Phase 4A clearance in March — confirming that a delivery-standard aircraft is real, not theoretical. Lufthansa's CEO expressed confidence in March that the first 777-9 will be delivered in 2027. A clean April first flight makes that credible. A slip into May or beyond starts to compress the certification timeline in ways that 2027 delivery targets cannot easily absorb. Lufthansa's patience has been tested. MAX 7 and MAX 10: Progress With Caveats The narrowbody certification story is more nuanced. Both MAX variants are held up by the same technical issue: a potential engine anti-ice system problem in which ice accumulation in rare icing conditions could damage engines or affect thrust performance. This issue links the approval timelines of both aircraft. The good news: the FAA cleared the MAX 10 for Phase 2 — the final stage — of its Type Inspection Authorization flight testing in late December 2025, with Boeing beginning those tests in early January 2026. Boeing has completed the engine anti-ice redesign and is now seeking FAA acceptance of its certification plan. The customer signal is cautiously positive. Ryanair CEO Michael O'Leary told reporters on March 20 that Boeing expects MAX 7 certification in 2Q and MAX 10 certification in 3Q26 — approximately six months ahead of Ryanair's first 15 MAX 10 deliveries planned for spring 2027. Southwest Airlines CEO Bob Jordan indicated he expects MAX 7 certification by 3Q26, with Southwest as launch operator. However, in Boeing's March O&D numbers, there is a mysterious 17 MAX 7 cancellation. The reason for the cancellation has not been disclosed; at this stage in the certification process, a 17-aircraft cancellation is a signal worth watching. WestJet, the MAX 10 launch customer, is planning to enter service in late 2026 or early 2027. Three MAX 10 in test flight now bear WestJet colors. The honest caveat: the MAX 10 is not certified yet, and Boeing has missed previous targets. The FAA has made clear it will not relax safety requirements to accommodate Boeing's commercial timeline. These are not procedural boxes to check — the engine anti-ice fix is a substantive technical requirement. Why It Matters Beyond the Variants Themselves Airbus can't keep up with demand for the A321neo - the market needs the MAX 10. Until MAX 10 certification is complete, Boeing cannot begin full-scale MAX 10 production at Everett — leaving one of its most commercially important derivatives effectively on standby. The fourth assembly line — the North Line — is built specifically for the MAX 10. Every month of certification delay is a month of that line's capacity sitting idle. The competitive read-across is direct. While Boeing works through certification, Airbus has continued executing in the high-capacity narrowbody segment with the A321neo at scale. The MAX 10 is Boeing's answer to the A321neo. Until it's certified, that answer remains incomplete. Bottom Line Boeing is running two certification programs simultaneously, and the stakes on each are different. The 777-9's first production flight this month is a milestone — proof that the program has moved from testing to delivery preparation. The MAX 7 and MAX 10 are moving, but on a timeline where any further slip starts to create real competitive and financial consequences. 2Q and 3Q are the windows to watch. Boeing has said thoroughness over speed. The FAA has said the same. The question is whether that shared philosophy produces certified aircraft before the year runs out.
