Circumstances:
On a flight from Porto Alegre to Rio de Janeiro, while cruising at an altitude of 33,000 feet, the aircraft entered an uncontrolled descent. The crew did not send any distress call. The aircraft descended with a rate of 20,000 feet per minute. At an altitude of 1,500 feet, it disintegrated in the air and eventually crashed. Both pilots were killed.
Probable cause:
It is believed that the crew failed to prepare the flight according to published procedures, did not follow the pre-departure checklist and failed to verify the position of the pressurization mode selector prior to take off. At an altitude of 33,000 feet, after suffering hypoxia, both pilot lost consciousness and situational awareness. Maybe one of them fell and the control column, causing the aircraft to enter an uncontrolled descent.

Circumstances:
Following an uneventful charter flight from Berlin, the crew was cleared to descend from FL140 and started the approach to Salzburg-Wolfgang Amadeus Mozart Airport. After being established on the ILS, the crew was cleared to land when, on short final, the aircraft stalled and crashed in a wooded area located in Freilassing, about 5,5 km short of runway 16, bursting into flames. The aircraft was destroyed by impact forces and a post crash fire and all 10 occupants were killed. At the time of the accident, severe icing conditions were reported in the area.
Probable cause:
The exact cause of the accident could not be determined with certainty. It was reported that the aircraft' speed dropped on short final, causing the aircraft to stall. It was not established if the stall was the consequence of icing or not as the aircraft was totally destroyed by a post crash fire and no trace of any icing was found on the wreckage. It was also reported that the electrical system failed on approach, causing the autopilot system to be disconnected and the attitude indicator to be out of service.

Circumstances:
The flight was cleared for the VOR/DME approach to runway 17 at the Marco Island Airport. The CVR recorded conversation between the pilot and co-pilot reference to the approach, specifically the MDA both in mean sea level and absolute altitude for a straight-in-approach to runway 17. The flight crew announced that the flight was landing on runway 35. The flight crew did not discuss the missed approach procedure nor the circling minimums. The flight continued and the co-pilot announced that the flight was 5 miles from the airport to descend to the MDA to visually acquire the airport. While descending about 8.5 feet of the left wing of the airplane was severed by a guy wire about 587 feet above ground level from an antenna that was 3.36 nautical miles from the threshold of runway 17. The tower is listed on the approach chart that was provided to the flight crew. The airplane then rolled left wing low, recovered to wings level, then was observed to roll to the left, pitch nose down, and impacted the ground. A fireball was then observed by witnesses. The altimeters, air data computer, and pilot's airspeed indicator were last calibrated about 8 months before the accident. The co-pilots altimeter was found set .01 high from the last known altimeter setting provided to the flight crew. The CVR did not record any conversation pertaining to failure or malfunction of either the pilot or copilot's HSI, the DME or Altimeters. There were no alarms from the VOR/DME monitoring equipment the day of the accident. The flight crew of another airplane executed the same approach about 30 minutes before the accident and they reported no discrepancies with the approach. The MDA for the segment of the approach between where the tower is located is no lower than 974 feet above ground level.
Probable cause:
The pilot's disregard for the MDA for a specific segment of the VOR/DME approach which resulted in the inflight collision with a guy wire of an antenna and separation of 8.5 feet of the left wing.

Circumstances:
On final approach to Walker's Cay Airfield, the aircraft was too low and struck the ground few metres short of runway threshold. Out of control, it rolled to the right when the right wing collided with a tree and was torn off. The aircraft rolled for another 100 metres before coming to rest, bursting into flames. All five occupants were injured and the aircraft was destroyed.
Probable cause:
The runway at Walker's Cay is less than 800 metres which is insufficient for such aircraft. The crew elected to land as early as possible but landed too short, causing the aircraft to crash.

Circumstances:
The descent to Allendorf-Eder Airport was completed in poor weather conditions. On approach, the captain cancelled the IFR flight plan and decided to initiate a go-around procedure for unknown reasons. The aircraft nosed down to 30° then rolled to the right to 60° and crashed in a wooded area. Both pilots were killed. It was reported that the copilot was the PIC at the time of the accident.
