Piper PA-31 Cheyenne

The flight crew was advised prior to initiating the approach that visibility at the airport had decreased to 1/8 mile with light rain, fog and obscuration. Published landing visibility minimums for the approach was 1 mile. The 150 feet wide runway had been plowed 100 feet wide, and there were snowbanks up to 3 feet high on both sides. The airplane touched down on the unplowed portion of the runway onto a snowbank, collapsing the landing gear. The flightcrew stated that the approach lights and runway were in sight during the entire approach, and that the second pilot told the pic that he was too far left and needed to correct to the right as the airplane was about to touchdown. The tower controller stated that he lost sight of the airplane as it landed due to fog.

En route at FL240, the plane entered a left spiraling descent and subsequently experienced an inflight break-up at 7,000 feet with separation of outboard wings, tail sections and internal vinyl from the nose baggage door. There was no distress call. Witnesses heard the engines and an explosive sound, then they saw the plane in a spin, trailed by falling debris. Debris was strewn over a distance of about 3.5 miles. Light weight pieces including vinyl from the baggage door, wing skin, and tail skin pieces were among the 1st debris on the wreckage path. Tail sections were found about 2.5 miles from the main wreckage with evidence of overload failure; pieces of the wings were found with evidence of downward/overload separation. No preexisting airframe failure was found that would have led to loss of control, inflight breakup, loss of pressurization or hypoxia. The plane was inactive for about 2 years before being purchased 2 months before accident. Last annual inspection was on 6/8/92. Icing was forecast from 9,000 feet to 17,000 feet msl; turbulence was forecast below 8,000 feet msl. Both occupants were killed.

On approach to Montreal-Dorval Airport, the pilot contacted ATC and reported longitudinal control problems. The aircraft started to roll left and right and the pilot maintained control using considerable aileron and rudder inputs. On short final, the twin engine aircraft crash landed short of runway 24L and came to rest in a grassy area. The pilot was injured and the aircraft was damaged beyond repair.

On final approach to Nairobi-Wilson Airport runway 07, during the last segment, the twin engine airplane lost height and landed hard. It bounced and landed hard a second time, causing the nose gear to collapse while taxiing for the apron. There were no casualties but the aircraft was damaged beyond repair. At the time of the accident, weather conditions were good but strong winds were reported.

The pilot tried to activate the radio-controlled runway boundary lights about 10 miles away, and also while he was in the traffic pattern, but he was unsuccessful. He continued his descent to approximately 500 feet above the ground using the vasi (visual approach slope indicator) lights. The pilot stated that he had the airport in sight and' felt well enough in sight to complete landing.' The airplane touched down in approximately 18 inches of snow 60 feet off the right side of the runway. The pilot reported that there was no mechanical malfunction. He said as he got closer to the ground he realized it was snow-mobile tracks and not the runway. He tried to go-around but the airplane impacted the ground collapsing the nose gear.

Shortly after takeoff from Cologne-Bonn Airport, while in initial climb, the pilot declared an emergency and was cleared to return. While completing a turn, he lost control of the airplane that entered a dive and crashed onto a house located in Lind, less than 2 km south of the airport. The pilot, sole on board, was killed. There were no casualties on the ground.

The pilots had entered into an agreement with the 5 pax to fly them to a ski resort. The airplane owner stated that the pic, who was the company pilot, did not have permission to use the airplane, nor did the owner know the pax. The airport at the ski resort is located in mountainous terrain at 6,750 feet msl. There is no instrument approach. There is no record of any weather briefings. The airplane collided with terrain (Mt Clark) at about 6,580 feet msl approximately 7.5 miles southwest of the destination airport. Weather for the area was: mountains locally obscured 3,000 to 5,000 feet scattered to broken with tops to 9,000, and widely scattered visibilities below 3 miles with snow and rain showers. Examination of the wreckage and impact site revealed the aircraft collided with the brush and snow covered 45° slope in a level left turn. All seven occupants were killed.

The twin engine aircraft departed Salzburg on a charter flight to Altenrhein, St Gallen, carrying five passengers and one pilot. On approach to Altenrhein Airport, the pilot encountered poor weather conditions. Unable to locate the runway due to low visibility, he abandoned the approach, initiated a go-around procedure and was cleared to divert to Friedrichshafen-Bodensee Airport that he reached few minutes later. On final approach, the aircraft stalled and crashed in a field located short of runway threshold. The aircraft was destroyed upon impact and all six occupants were killed. At the time of the accident, weather conditions were poor.

The pilot made routine radio communications in preparation for takeoff. The airplane departed from runway 25 in daylight instrument meteorological conditions (IMC) with light snow and fog. Shortly after takeoff, the airplane's radar target disappeared from the controller's scope. The airplane crashed on wooded terrain about two miles south-southwest of the departure end of runway 25. Impact occurred in an steep, nose down, left wing low attitude. The airplane was destroyed by ground impact forces and a post-impact fire. No physical incapacitation of the pilot-in-command was determined. No contributory mechanical malfunctions of the airplane were discovered. All three occupants were killed.

The flight was level at 10,000 feet msl in IMC conditions when the controller noticed the airplane take a sharp right turn and descend rapidly. Attempts to contact the flight were negative. Examination of the accident showed all the major components present, however, impact damage precluded any flight control continuity check. The engines could not be recovered from the impact crater. The accident site was not accessible with specialized equipment. The pilot, sole on board, was killed.
