Circumstances:
For unknown reasons, the four engine airplane landed hard at Bucaramanga-Palonegro Airport and bounced several times before landing firmly on the last third of the runway. Aware that he would be unable to stop the airplane within the remaining distance, the captain decided to veer off runway and made a sharp turn to the right when both left main gear and nose gear collapsed. Both left engines struck the ground and the airplane veered off runway and came to rest. All 22 occupants were evacuated safely while the aircraft was damaged beyond repair.

Circumstances:
The aircraft was completing a regular schedule flight from Kristianstad to Stockholm-Bromma with intermediate stop in Växjö and Jönköping, carrying 19 passengers and a crew of three on behalf of Linjeflyg. On approach to Bromma Airport, the crew encountered marginal weather and icing conditions. At an altitude of 1,150 feet and a speed of 137 knots, flaps were deployed at an angle of 40° when control was lost. The airplane entered a nose down attitude and crashed at an angle of 110° and a speed of 210 knots in a parking lot located in the residential area of Kälvesta, about 4,5 km short of runway 12 threshold. The aircraft was totally destroyed by impact forces and a post crash fire and all 22 occupants were killed. At the time of the accident, weather conditions were considered as marginal with icing conditions and a horizontal visibility of 5 km with a cloud base at 700 feet.
Probable cause:
Loss of control on final approach due to an excessive accumulation of ice on the horizontal stabilizers after the crew lower the flaps from 32° to 40°. When control was lost, both right engines n°3 and 4 were not running at full power for undetermined reasons, which caused the deicing system to produce an insufficient temperature.

Circumstances:
The airplane departed Quito-Mariscal Sucre Airport at 0806LT on a regular schedule flight EH232 to Cuenca, carrying four crew members and 55 passengers. At 0827LT, while cruising at 18,000 feet, the crew reported over Ambato. Eight minutes later, while cruising in limited visibility, the four engine airplane struck the slope of Mt Chimborazo (6,263 metres high). As the airplane failed to arrive at destination, SAR operations were initiated but eventually suspended few days later as no trace of the aircraft nor the 59 occupants was found. The wreckage was apparently localized on 17 October 2002 and a team of 20 alpinists was able to reach the crash site on 18 February 2003. Debris of the airplane were found, confirming this was flight EH232.
Probable cause:
Controlled flight into terrain.

Circumstances:
While descending to Porlamar-Del Caribe-General en Jefe Santiago Mariño Airport, the crew encountered poor weather conditions with low visibility and heavy rain falls. In accordance with ATC, the crew decided to divert to Cumaná Airport and while completing a turn to change heading, the four engine airplane struck the peak La Gloria located about 10 km northeast of Porlamar Airport. The wreckage was found eight meters below the summit and the copilot, seriously injured, was evacuated to an hospital in Caracas while 47 other occupants were killed. 17 days later, the copilot Ivan Rodolfo Magallanes died from his injuries.
Probable cause:
It is believed that the crew may have lost his orientation during the few seconds preceding impact with the ground, maybe following a malfunction of several instruments whose parameters were probably badly influenced by static electricity accumulated in the stormy weather. At the time of the accident, hurricane 'Alma' was approximately 100 km east of Margarita Island.
