Total fatalities:

Circumstances:
The aircraft was engaged in charter flight in Colombia on behalf of the National Bank of Colombia, carrying four passengers, two pilots and a load of bank notes. Following a wrong approach configuration, the aircraft landed too far down the runway 32 (1,860 meters long) at Montería-Los Garzones Airport. Unable to stop within the remaining distance, the aircraft overran, lost its nose gear and both engines and came to rest 95 meters further. All six occupants escaped uninjured while the aircraft was damaged beyond repair.
Probable cause:
Poor approach and landing planning on part of the crew who continued the approach at a too high altitude, causing the aircraft to land too far down the runway, reducing the landing distance available. Poor crew coordination and the failure of the crew to initiate a go-around were considered a contributing factors.

Circumstances:
While approaching Ibagué-Perales Airport, the crew encountered poor weather conditions and was unable to locate the runway. In such conditions, the captain decided to initiate a go-around procedure and informed ATC that he would divert to the alternate airport if a second attempt-to-land would be abandoned. Few minutes later, while flying at an altitude of 5,000 feet, the aircraft struck the slope of Mt Saludo located 5,6 km west of the airport. The aircraft was destroyed by impact forces and all 15 occupants were killed.
Probable cause:
Controlled flight into terrain after the aircraft deviated from the published go-around route for unknown reasons.
