Boeing’s Brand New 777-9 Makes First Flight

Boeing’s test campaign involving the 777-9 continues to inch closer to completion, with another important puzzle piece added to the jigsaw in the seventh model completing its first flight.

The seventh aircraft, having now completed its first flight, will immediately begin the relevant ETOPS and function-and-reliability testing that is the last step in getting the upcoming long-haul jet certified.

The roughly three-hour flight over Washington, Idaho, and Oregon for Boeing is part of efforts to get the final stretch of deliverables for certification over the line.

Boeing’s New Production 777-9 Joins The Testing

The new aircraft lifted off from Paine Field in Everett and returned to the same location at 1735 PT. It followed a standard first-flight profile that aligns closely with other test units. The jet was flown by Capt. Dan Mangel and Capt. Jake Miller.

Onboard the aircraft were system operators, analysts, and specialists whose job was to track the jet’s behaviour during its first flight and, in real time, analyze the key structures and systems installed on the 777-9 to validate its safety and integrity.

Boeing says the 777-9 performed beautifully, and this not being a prototype but rather a production-configured jet is a step in the right direction. The manufacturer adding the performance, seeing no anomalies, and completing its tasks safely is key in ongoing efforts to get the unit certified.

ETOPS Becomes The Focus

With the seventh Boeing 777-9 now taking flight, attention turns immediately to moving through the remaining pillar preventing certification; this airframe is being prepared for ETOPS testing.

ETOPS testing, flagged by the Federal Aviation Administration (FAA), which is overseeing the campaign, and Boeing, is a process that allows the twin-engine widebody to fly for extended periods and across long distances that are far from diversion airports. ETOPS approval is crucial to unlocking transoceanic flying, especially, and saving necessary time and fuel while route planning is conducted.

For the 777-9 especially, a widebody flagship not only intended to carry strong numbers but also fly long distances, ETOPS is a vital asset in certification so it can conduct the operations it was launched for. Boeing is using the production jet to test the capabilities of not just a plane destined for an airline, but to check off further boxes critically.

The ETOPS campaign comes immediately after years of extensive testing across the 777-9 fleet designated for the certification campaign, from ground tests to engines, and the now flight test process that is nearing its endpoint. The campaign has seen more than 4,800 flight test hours alone and many thousands more on the ground and in labs.

For Boeing, the pathway to certification has been unlike any other; the debut of the 777-9 came in an era where the planemaker saw quality and safety lapses take centre stage across multiple existing commercial aircraft programmes.

Unfortunately for the 777X, as a direct consequence of Boeing’s missteps in other divisions, this was made to be an example for the FAA, which has not only set new standards in the certification process but has also been less lenient than it once was in approving new jets.

Over time, the delays to the 777-9 have compounded, and a 2027 expected certification and first delivery will come seven years after initial expectations. While airlines have been patient, they have equally been frustrated at what has transpired, as much as Boeing, which wants its new flagship in the skies, but safely.
