Gulfstream G650

On April 2, 2011, about 0934 mountain daylight time, an experimental Gulfstream Aerospace Corporation GVI (G650), N652GD, crashed during takeoff from runway 21 at Roswell International Air Center, Roswell, New Mexico. The two pilots and the two flight test engineers were fatally injured, and the airplane was substantially damaged by impact forces and a post crash fire. The airplane was registered to and operated by Gulfstream as part of its G650 flight test program. The flight was conducted under the provisions of 14 Code of Federal Regulations Part 91. Visual meteorological conditions prevailed at the time of the accident. The accident occurred during a planned one-engine-inoperative (OEI) takeoff when a stall on the right outboard wing produced a rolling moment that the flight crew was not able to control, which led to the right wingtip contacting the runway and the airplane departing the runway from the right side. After departing the runway, the airplane impacted a concrete structure and an airport weather station, resulting in extensive structural damage and a post crash fire that completely consumed the fuselage and cabin interior.

The pilot allowed the aircraft to stall at an altitude which was too low to effect recovery before ground impact occurred. He was in the process of performing VMC test and maximum performance single engine climbs during the test flight. Witness description of the aircrafts movements at the beginning of the accident sequence suggests that the VMC test were in progress immediately before the accident occurred. Both occupants were killed.

The aircraft had been on sales demonstration flights and was on a delivery flight from Memphis, TN to Dallas, TX. The plane was observed departing at 1550 CDT in a max performance climb. Radar info from mode C of the transponder returns indicated that the aircraft climbed from 1,000 to 16,000 feet in 7 min and 14 seconds. Level flight was indicated at 16,300 ft from 1558:16 to 1601:17 CDT. The last alt return was from 16,000 ft at 2201:07. Two more returns were received at 2201:49 and 2202:08, but with no altitude readout. At about that time, the aircraft was observed spiraling down, counterclockwise, with a portion of the left wing missing. The wing tip (outer wing panel outboard from about wing station 190), left aileron and left engine tail cone panel were found about 3 miles from the main wreckage impact point. An examination revealed that the wing panel separation occurred upward from positive overload forces. No evidence was found of fatigue or pre-existing failure. Light to moderate turbulence was reported between 14,000 and 18,000 ft msl. The pilot, sole on board, was killed.
