MIAMI — Boeing announced that General Electric-powered 787-9s have received a go-ahead by the FAA on Friday. The airplanes are thus cleared for delivery.

The green-light clears all existing engine types for the jet to fly. The stretched Dreamliner offers two options, the GEnx manufactured by General Electric and the Trent 1000 manufactured by Rolls Royce.

Flight testing to certify the GEnx-powered 787-9 was conducted on-board United Airlines bound N-38950 (LN181). The plane made its first flight on July 11th and is now awaiting delivery in Everett, Washington. N-38950 will be the first of 26 787-9 aircraft bound for the Chicago carrier, which currently operates a growing fleet of 787s including the original -8 model.

A Rolls Royce-powered 787-9 variant received its type certification in late June, and has since seen aircraft delivered to Air New Zealand and All Nippon Airways.

Production the the 787-9 has greatly increased in recent weeks due to both types receiving their amended type certificates. At this time, 10 787-9’s have completed final assembly with two deliveries (Air New Zealand and All Nippon Airways). The Boeing North Charleston plant is expected to begin production of their first 787-9 later this fall when line number 269 destined for United Airlines comes around.

Any induction of a new plane type brings new customer aircraft as well. The next few months will welcome many planes rolling off of the Everett assembly line destined for new carriers to the 787 program. Some newcomers to the 787-9 family will include Etihad, Scoot Airlines, and Virgin Atlantic.
