Rockwell Gulfstream 690C Jetprop 840

Crashed in unknown circumstances while approaching La Carlota-General Francisco de Miranda Airport. Both pilots were killed.

While in a descent for arrival at the destination airport, the aircraft sustained structural failure with the right outer wing, horizontal stabilizer, and vertical stabilizer separating from the aircraft. The aircraft impacted approximately 10 miles from the planned destination. According to radar data and other research, the descent was conducted at vne and known severe turbulence was present in the area at the time of the accident.

About 30 minutes into the flight, the pilot informed ATC about his position when contact was lost. It was later reported that the aircraft has been hijacked and crashed landed somewhere in the Sur Cayambe province. All seven occupants were released but the aircraft was damaged beyond repair.

On October 11, 1990, about 1730 Alaska daylight time, a wheel-equipped Gulfstream Aerospace 690C Turbine Commander airplane, N45Q, is presumed to have crashed in the Arctic Ocean about 200 miles north-northwest of Deadhorse, Alaska. Neither the airplane nor its occupants have been located. The airplane was being operated by the US Department of the Interior, as a visual flight rules (VFR) public use local game management flight, for the purpose of locating radio collared polar bears, when the accident occurred. The airplane, registered to Bowhead Equipment Company of Seattle, Washington, and operated by Alaska Helicopters, Inc. of Anchorage, Alaska, is presumed to have been destroyed. The certificated airline transport pilot, and the two passengers, are presumed to have received fatal injuries. Visual meteorological conditions prevailed at the point of departure. A VFR flight plan was filed by the pilot for a 5.5 hour flight originating and terminating at Deadhorse. The accident flight originated at the Deadhorse Airport about 1429. According to information received from the Federal Aviation Administration's (FAA), Air Route Traffic Control Center, radar contact was lost with the accident airplane while it was maneuvering at 22,000 feet msl, about 200 miles north-northwest of Deadhorse. The accident airplane did not reach the intended destination of Deadhorse, and was not located at any airport. The FAA issued an alert notice (ALNOT) at 2221. Search personnel began an extensive search effort that included a high altitude, special radar-equipped airplane, surface vessels, and ground search personnel. The search was suspended on October 26, 1990.

Crashed in unknown circumstances while on a flight from Cali to Bogotá. Both occupants were killed.

While on final approach to runway 09 the aircraft struck a 42 feet power pole with the right wing. The wing was torn from the aircraft. The aircraft landed inverted 400 feet east of the pole. The runway threshold lights are displaced 165 feet from the runway end for night operations. Reil lights are located at the runway end. A power line crosses the extended centerline 825 feet west of the runway end. Red obstruction lights mark the tops of the poles. On the night of the accident the obstruction lights were inoperative. Witnesses reported that the aircraft appeared to be flying lower than normal in the traffic pattern. 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.

While on a LOC/DME approach to Patterson-Harry P. Williams Airport in marginal weather conditions, the pilot was completing a left turn when the airplane collided with trees and crashed. Both occupants were killed.

On final approach to Parys Airport, the twin engine airplane went out of control and crashed few hundred meters short of runway, bursting into flames. All five occupants were killed.
