Boeing’s 777-9 flight test programme continues to progress, with the seventh prototype aircraft, registered N2008K, successfully completing its maiden flight.
The flight lasted around three hours and was conducted over the U.S. states of Washington, Idaho and Oregon, marking another significant milestone for the test fleet.
Following its first flight, the aircraft will be prepared for ETOPS certification testing, a critical requirement for long-haul operations. These tests are designed to demonstrate that a twin-engine aircraft can operate safely over oceans and remote areas far from suitable diversion airports.
According to Boeing, the combined flight time of the 777-9 test fleet has now exceeded 4,800 hours.
Another notable milestone saw five Boeing 777-9 prototypes operating simultaneously within a 24-hour period. Six flights were conducted over two days, generating around 18 hours of test activity. Aircraft systems, engines and cabin equipment were evaluated, while the seventh prototype completed its first flight. Various ground tests were also carried out in parallel.
Boeing aims to complete certification of the 777-9 and begin initial deliveries in 2027.
