Circumstances:
After takeoff from Karsi Airport, the aircraft climbed at an insufficient speed of 470 km/h with a max speed of 515 km/h. The cruising altitude of 11,600 meters was reached after 40 minutes and 20 seconds. The speed dropped to 400 km/h then the aircraft reached a critical angle of attack (+20°) when vibrations started. The crew misinterpreted these vibrations and failed to judge properly the situation in reducing the engine power to idle. The speed dropped to 290 km/h when the aircraft stalled and entered a spin. The aircraft eventually went into a flat attitude and crashed in an isolated and desert area located in the region of Ushquduq. The aircraft was totally destroyed upon impact and all 200 occupants were killed.
Probable cause:
It was determined that the climb configuration was incorrect and the crew led the aircraft adopting a critical angle of attack once the cruising altitude was reached. This situation affected the air flow into the three engines and the aircraft went into inappropriate flight conditions. The crew misinterpreted the situation and failed to identify the wrong flight configuration until the aircraft entered stall condition.

The crew was returning to Germany following an expedition in the South Pole (Antarctica). The aircraft departed Dakar on a leg to Lanzarote, and was following another Dornier DO228 from the same Alfred Wegener Institute christened Polar 2 that was flying higher than Polar 3. En route, the aircraft was shot down by a surface-to-air missile and crashed in a desert area located south of Dakhla. All three crew members were killed.
Probable cause:
Shot down by a surface-to-air missile from the Front Polisario.

Circumstances:
The aircraft was found where it had crashed and burned on a rough lava bed. The crash site was about one mile northeast of a road where drug smuggling aircraft had been known to land in the past. There was evidence that cocaine had been removed from the accident site. The wreckage had been camouflaged by placing lava rocks on the shiny pieces of metal. There was evidence that the plane had crashed in a left wing low attitude while in a landing configuration. No preimpact/mechanical part failure or malfunction was found. The elevation of the crash site was about 2,930 feet. The aircraft wreckage was discovered on 6/2/84. The actual time of the accident was not determined. Both occupants were killed.
Probable cause:
Occurrence #1: in flight collision with terrain/water
Phase of operation: unknown
Findings
1. Stolen aircraft/unauthorized use - performed - pilot in command
2. (f) terrain condition - rough/uneven
3. (c) clearance - misjudged - pilot in command

Circumstances:
The non-instrument rated pilot was on ferry flight from Bartlesville, OK to Ontario, CA. An en route stop was made at Tucumcari, NM, where the aircraft was refueled and 14 qts of oil was added to the left engine. The line boy who serviced the aircraft saw no visible oil leaks or spillage around the engine. While on the next leg of the flight, the aircraft crashed near interstate highway 40. Two witnesses that saw the crash stated rain was falling, the wind was blowing very strong and there were low ceilings. Reportedly, a squall line was moving thru the area and there was moderate to severe turbulence. An exam of the wreckage revealed the aircraft had crashed in a steep nose down attitude, with 20° to 30° left bank and at high speed. No preimpact, mechanical failures were found and both engines had evidence that they were operating during impact. The weather briefer said the pilot indicated he would fly around the area of precipitation and remain VFR. Radar info showed the pilot had been following the interstate highway and varying his alt between 7,900 and 6,300 feet msl. Both occupants were killed.
Probable cause:
Occurrence #1: in flight encounter with weather
Phase of operation: cruise - normal
Findings
1. (f) flight into known adverse weather - initiated - pilot in command
2. (f) light condition - dark night
3. (f) weather condition - low ceiling

5. (f) weather condition - rain
6. (c) VFR flight into IMC - continued - pilot in command
