South America

The following factors were identified:
- Attention – undetermined.
It was found the possibility that the PT-ONJ aircraft crew had their attention (focused vision) on the runway at the expense of maintaining proper separation with the terrain on a visual approach.
- Piloting judgment – a contributor.
Regarding the approach to landing profile, there was an inadequate assessment of the aircraft's operating parameters, since the downwind leg was elongated by a significantly greater distance than that expected for a "Category B" aircraft in landing procedures under VFR.
- Memory – undetermined.
It is likely that, based on the experience of ten years of operation in a company governed by the RBAC 121, the PIC procedural memory has influenced the decisions made concerning the conduct of the aircraft. The habit of performing long final approaches in another type of operation may have activated his procedural memory, involving cognitive activities and motor skills, making the actions automated in relation to the profile performed in the accident.
- Flight planning – undetermined.
A possible non-use of the available aeronautical charts (CAP 9453 and WAC 3189), which were intended to meet the needs of visual flight, may have contributed to low situational awareness about the characteristics of the relief around the SNCT Aerodrome and the presence of the power grid that interfered with the aircraft's landing approach.

The accident was the consequence of a controlled flight into terrain after the decision of the pilot to continue the flight under VFR mode in IMC conditions.
The following contributing factors were identified:
- The pilot took the decision to continue the flight to destination instead of returning to Flandes (Girardot) or to divert to the alternate airport,
- A low situational awareness on part of the pilot who failed to take into account the geographical environment and to maintain a safe separation from the terrain.
