De Havilland DHC-6 Twin Otter

The aircraft departed overweight for a 17-hour ferry flight. Early in the flight the crew experienced some fuel problems and decided to continue when they resolved the problem. The crew indicated the en route winds were close to forecast. The ferry fuel system is a simple 5- tank gravity fuel feed into the fore and aft main tanks. About 6 hours from destination, they realized the ferry tanks were not flowing into the main tanks as planned. They began manually transferring fuel from the rear ferry tank to the forward ferry tank, and shut down the right engine to reduce fuel consumption. This did not stop the negative fuel flow from the main tanks. At the time of ditching, the crew estimated the fuel remaining in the ferry tanks was about 170 gallons, most of which was in the 3 aft ferry tanks. An aero engineer calculated that the aircraft was at least 10 inches behind the maximum aft cg at the time of ditching, and suggested that the ferry fuel system was not managed to maintain the cg within the allowable limits, a task made more difficult with the rear fuselage cargo.

During the takeoff roll on runway 20 at Kathmandu-Tribhuvan Airport, the aircraft failed to get airborne, overran, went through a fence and came to rest in a field. A passenger and a pilot were killed while all other occupants were rescued.

En route from Bima to Ruteng, the crew encountered poor weather conditions. Control was lost and the aircraft crashed in the Molo Strait off Rinca Island. All 14 occupants were killed.

The crew was engaged in a local training flight at Bili Airfield. During the takeoff roll on a grassy airstrip, the crew lost control of the airplane that veered off runway, lost its undercarriage and came to rest. Both pilots escaped uninjured and the aircraft was damaged beyond repair.

The twin engine aircraft departed Tabubil and a regular schedule flight to Selbang, carrying 26 passengers and two pilots. After passing over Olsobip, the crew encountered poor visibility due to clouds. While flying at an altitude of 6,400 feet in clouds, the aircraft struck the slope of a mountain located about 9 km south of Selbang. The aircraft was destroyed and all 28 occupants were killed. At the time of the accident, the cloud layer was reported from 4,000 to 10,000 feet.

The twin engine aircraft departed Rothera Station runway 18 on a charter flight to Terra Nova, carrying two passengers and two pilots. During initial climb, the airplane became unstable and rolled side to side. From a height of about 100 feet, it stalled and crashed on the slope of an iceberg facing the airport, bursting into flames. All four occupants were killed.

The twin engine aircraft was completing a charter flight from Nabire to Obano, carrying two passengers and two pilots on behalf of the Nabire Bakti Mining Company. While approaching the destination, the crew encountered clouds when the aircraft collided with Mt Deyjay (2,115 metres high) located about 8 km southwest of Obano. All four occupants were killed.

The captain, first officer, and two passengers departed from the Fish Egg Inlet logging camp, located 56 nautical miles (nm) north of Port Hardy, British Columbia, for a 16 nm visual flight rules (VFR) flight to Pruth Bay. This was the second leg of a flight which had originated at Port Hardy. The first officer, who occupied the left pilot seat and was handling the controls, taxied the aircraft a short distance away from the dock and took off. The captain occupied the right pilot seat. As the aircraft climbed through 100 feet, and just as the flaps were retracting, the aircraft pitched up violently and stalled. The pilots were unable to regain control of the aircraft, and it crashed into the water about 100 feet from the shore and sank immediately. The captain, who sustained serious injuries from the crash, escaped from the wreckage and swam to shore. The first officer and the two passengers remained in the aircraft and drowned. When the aircraft failed to arrive at Pruth Bay, personnel from Pacific Coastal Airlines (the company) notified the Rescue Coordination Centre and started their own search. A search pilot spotted debris in the water near the logging camp at about 1430 Pacific daylight saving time (PDT) that day. He landed to investigate, found the captain on the shore nearby, and transported him to the Port Hardy hospital. The accident occurred during daylight hours at approximately 1148 PDT, at latitude 51°36'N and longitude 127°41'W. There were no witnesses, other than the aircraft captain, to this accident.

While descending to Abuja-Nnamdi Azikiwe Airport, the crew encountered poor weather conditions with low clouds, heavy rain falls and moderate to severe turbulences. As the ILS was out of calibration, the crew decided to perform a VOR/DME approach but following a misunderstanding of the VOR location, the crew started the final approach prematurely. Too low, the aircraft struck the slope of a mountain located 12,2 km short of runway 22. Two people survived while three others were killed.

En route from Taura to Latacunga, the crew was cleared to climb to FL155 when, at an altitude of 13,400 feet, the twin engine aircraft stuck the slope of Mt Lozan shrouded in clouds. All 17 occupants were killed. The wreckage was found 100 metres below the summit.
