Official Findings

According to the official investigation, the accident was the consequence of a controlled flight into terrain in below-minima weather conditions. The captain decided to conduct the flight despite poor weather and failed to return, violating all established procedures.

Additionally, the meteorologist had published bulletins with inaccurate information, as weather conditions were worse than predicted. Mismanagement of the flight, poor organization of operations, and poor decisions by various actors involved in organizing the flight were considered contributing factors.
