Deadhorse

The crew was conducting a GPS instrument approach in a Douglas DC-6B airplane under IFR conditions. Both pilots were certificated and type-rated in the Douglas DC-6B airplane. The first pilot, seated in the right seat, was one of the company's senior check airman, and possessed a right seat dependency endorsement. The second pilot, seated in the left seat, had less experience in the DC-6B airplane. It had been previously agreed that the second pilot would fly the leg of the flight on which the accident occurred. The first pilot reported that light snow showers were present, with visibility reported at 4 miles. During final approach as the airplane passed over the airstrip threshold, a higher than normal sink rate was encountered. He said that the initial touchdown was "firm," but was thought to be within acceptable tolerances. Just after touchdown, the left wing broke free from the airplane at the wing to fuselage attach point. The airplane veered to the left, continued off the left side of the 5,000 feet long by 75 feet runway, down an embankment, and came to rest in an area of wet, tundra covered terrain. A postcrash fire heavily damaging the center section of the fuselage. The cockpit voice recorder (CVR) revealed that as the airplane progressed along the approach, the first pilot says: "You're only one mile from it....Take it on down ah three." As the airplane passes over the runway threshold, the first pilot says: "Keep that, keep that (expletive) power off.... Just push forward on the nose." The sound of impact is heard 4 seconds later. The minimum descent altitude (MDA) for the approach is 400 feet msl (383 feet agl). A contract weather observer reported lower ceilings, with about 1 mile visibility, over the approach end of the runway at the same time as the accident.

The airline transport certificated pilot was landing at a remote village on a scheduled domestic commuter flight with nine passengers. The accident airplane, a twin-engine turboprop certified for single-pilot operations, was equipped with a fuselage-mounted belly cargo pod. Witnesses saw the airplane touch down on the gravel runway with the landing gear retracted. The belly pod lightly scraped the runway for about 40 feet before the airplane transitioned to a climb. The propeller tips did not contact the runway. As the airplane began climbing away from the runway, the landing gear was extended. The airplane climbed to about 100 to 150 feet above the ground, and then began a descending left turn, colliding with tundra-covered terrain. A postcrash fire destroyed the fuselage, right wing, and the right engine. The flaps were found extended to 40 degrees. The balked landing procedure for the airplane states, in part: "power levers to maximum, flaps to 15 degrees, landing gear up, and then retract the flaps." Five passengers seated in the rear of the airplane survived the crash. The survivors did not recall hearing a gear warning horn before ground contact. The airplane was landed gear-up eight months before the accident. The airplane was nearly landed gear-up four months before the accident. Each time, a landing gear warning horn was not heard by the pilot or passengers. A postcrash examination of the airplane and engines did not locate any preimpact mechanical malfunction. The FAA's Fairbanks, Alaska, FSDO conducted an inspection of the operator six months before the accident, and recommended the operator utilize two pilots in the accident airplane. Following the accident, the Fairbanks FSDO required the operator to utilize two pilots for passenger flights in the accident airplane make and model.

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.

During initial climb, the cargo shifted, causing the aircraft to stall and to crash in flames within the runway. The aircraft was destroyed and all three crew members were killed.

During a final approach completed in limited visibility due to low clouds and fog, the crew failed to realize that his altitude was too low when the airplane struck the ground and crashed 914 metres short of runway threshold. Both pilots and four passengers were killed while two other passengers were seriously injured.

On approach to Deadhorse Airport, the crew encountered poor weather conditions when the airplane struck the runway surface 1,000 feet past its threshold. After initial impact, the left wing was torn off and the airplane went out of control. On a snow and ice covered runway, the airplane veered off runway to the left before coming to rest in flames few hundred yards further. All three crew members escaped uninjured while the aircraft was destroyed.

Following an IFR descent to Deadhorse Airport, the crew cancelled the IFR flight plan and continued under VFR mode. During the last segment, the crew failed to realize his altitude was too low when the right main gear struck the ground short of runway threshold and was torn off. Power was increased and decision was taken to make a go-around but the right engine failed to respond properly. The airplane stalled and belly landed, slid for 460 meters and came to rest. While both pilots were uninjured, the aircraft was damaged beyond repair.

The airplane was completing a cargo flight from San Francisco to Deadhorse with an intermediate stop in Fairbanks, carrying a crew of three and 17,000 liters of fuel. After touchdown on a gravel runway covered by snow and ice, control was lost. The airplane veered off runway to the left, contacted an embankment then came to rest on a road. All three crew members escaped uninjured while the aircraft was partially destroyed by fire.

During the takeoff roll, the right engine lost power. The pilot lost control of the airplane that veered off runway and collided with a snow bank. All three occupants were injured and the aircraft was damaged beyond repair.

While descending in marginal weather conditions, the pilot lost his orientation and descended too low without any ground reference when the airplane struck the ground and crashed 28 NM south of the airport. Two passengers were killed while three other occupants were injured.
