Boeing targets April for first production 777X flight
February 5, 2026
Following a review of company documents, Reuters reports that Boeing is preparing to fly the first production-standard 777X as early as April 2026.
It would be a pivotal milestone for a widebody programme that is already about six years behind schedule and has generated more than $15 billion in development charges.
First production 777X advances
The aircraft, which is currently undergoing fuel testing at Paine Field in Everett, is destined for launch customer Lufthansa. The first flight will support certification—regulators require testing with a delivery-configured production jet.
“In addition to the dedicated flight test fleet, some production aeroplanes will support testing that does not require flight-test unique equipment and instrumentation,” a Boeing spokesperson told Reuters.
Boeing still expects certification later in 2026 and potential entry into service in 2027, depending on airline readiness and regulatory progress.
Ongoing 777X programme risks: engine durability and programme delays
Despite the April flight target, uncertainties remain. GE Aerospace is analysing a potential durability issue involving a seal in the GE9X engine, which could require redesign or retrofit work during maintenance. Boeing leadership maintains that deliveries can still begin in 2027.
The 777X programme has already faced repeated delays tied to certification scrutiny and development challenges.
Training infrastructure ramps up ahead of 777X entry into service
Supporting the aircraft’s eventual rollout, CAE is installing Asia-Pacific’s first Boeing 777X full-flight simulator at the Singapore-CAE Flight Training Centre.
The 7000XR simulator will allow regional airlines to train crews locally as the aircraft approaches service entry, reflecting strong expected demand from operators such as Singapore Airlines, Cathay Pacific, ANA and Air India.
“The B777X is the latest widebody aircraft developed in the market and is central to many airlines’ long-haul strategies, particularly in Asia and the Middle East,” said Alexandre Prévost, President, Civil Aviation at CAE, in the company’s announcement. “
With this simulator in Singapore, we are providing the training infrastructure where it is needed most, at the crossroads of Asia-Pacific aviation. This will allow airlines to train their B777X pilots within their region.”
CAE says the Singapore deployment positions training capacity where it is needed most and provides carriers with practical access to 777X pilot preparation in the region’s fast-growing aviation market.
“This simulator gives airlines in the region a practical option to train their pilots closer to home, at a time when fleet renewal and growth are driving demand for widebody training. In addition, the B777X gives the Singapore-CAE Flight Training centre one of the most comprehensive Boeing training portfolios in the region,” Prévost added.
April’s first production 777X flight would clear a major hurdle for the troubled programme
If Boeing achieves a successful first production 777X flight in April, it would represent the clearest signal yet that the long-troubled flagship widebody is nearing certification and commercial service.
Yet unresolved engine questions and the programme’s history of delay make the coming months decisive—not only for the 777X itself, but for Boeing’s credibility in the long-haul aircraft market.
