About three minutes later, the aircraft stalled and collided with the Padre Amaya mountain, some 20-30 m below the summit at an altitude of 7147 feet (airfield elevation is 4940 feet). The aircraft had been overloaded by 170 lbs (77 kg).

Probable Cause:

PROBABLE CAUSES: "Failure of the crew in the flight technique applied during the take-off phase, by not evaluating the performance of the aircraft, considering the high weight in front of the obstacles to climb over on the ascent trajectory.
Contributing Factors:
- Errors presented in the dispatch, since the weights were not totaled correctly, possibly due to errors in the handling of cargo and unaccompanied luggage.
- Attitude of complacency on the part of the crew, due to excellent meteorological conditions that caused an excess of confidence in the planning of the flight on the part of the crew.
