A fourth aircraft is now part of the Gulfstream G650 flight-test program, Gulfstream Aerospace Corp. announced today. The newest ultra-large-cabin, ultra-long-range test aircraft flew for the first time June 6 and has spent more than five hours in the air.

Unlike its three predecessors, the fourth G650 (S/N 6004) is a production aircraft. S/N 6004 will be the first G650 outfitted and tested with a full interior, which will be installed later this summer. The aircraft, which will be used to evaluate the aircraft's cabin systems, is expected to resume flight testing following the installation.

"We're delighted with the performance we're seeing out of these aircraft," said Pres Henne, senior vice president of Programs, Engineering and Test, Gulfstream. "We're equally thrilled with the streamlined manufacturing process, which involves 50 percent fewer parts, bonded materials and precision build carts, which allow us to easily put aircraft pieces together. Our use of these advanced materials and systems - along with the three-dimensional solid models we utilized in the design process - have provided impressive results. We couldn't be more pleased."
