The airplane deviated from the prescribed flight plan when, at an altitude of 9,670 feet, it struck the slope of Mt Trujillo located in the region of Buenaventura, about 75 km northwest of Cali Airport. SAR operations were suspended after few days as no trace of the aircraft nor the crew was found. Eventually, the wreckage was found in a ravine on October 31st 1974. All 27 occupants were killed.

Circumstances:
The crew was completing a local training flight at Mariquita Airport. On final approach, the instructor simulated an engine failure and reduced the power on the left engine when the pilot-in-command lost control of the airplane that stalled and crashed 500 meters short of runway 18 threshold. Two pilots were killed while four others were injured.
Probable cause:
It was determined that the accident was the consequence of a poor crew coordination while the instructor failed to supervise properly the pilot under training. He also failed to pay sufficient attention to the approach configuration and failed to realize that the approach speed was too low.

Circumstances:
While descending to Cúcuta-Camilo Daza Airport in good weather conditions at an altitude of 7,000 feet, the four engine airplane went out of control and crashed on the slope of Mt San Isidro located near the Colombia - Venezuela border. The aircraft was totally destroyed and all 44 occupants were killed.
Probable cause:
Aircraft structure factor - tail unit, involving the failure in flight of the tailplane spar, so that the left tailplane and elevator became detached and control of the aircraft was lost. An examination of the aircraft wreckage revealed that the upper flange of the left tailplane spar had sustained a fatigue fracture, two distinct areas being visible, namely the area of progressive fatigue and the area of instantaneous failure. This evidence obviously explained the accident, since the already weakened structure was not able to withstand the loads imposed when the aircraft entered an area of turbulence. Laboratory tests subsequently carried out confirmed the failure.

Few minutes after takeoff from Cali-Palmaseca Airport at noon, while passing over Marmato beacon, the right engine failed. The crew was unable to feather the propeller when the engine caught fire. After few seconds, the crew was able to extinguish the fire and to feather the propeller but as the airplane lost too much altitude, the captain decided to attempt an emergency landing. The aircraft crash landed in a field located few km from the airport and came to rest. While both pilots were uninjured, the aircraft was damaged beyond repair.
Probable cause:
Detachment of an engine cowling in flight followed by the failure of the cylinder n°5 on the right engine.
