The dispatcher gave permission to descend to 300 meters for the fourth turn and provided landing conditions with a magnetic course of 127°.

Although these conditions were above the minimum, the actual weather had deteriorated significantly, with visibility at 3 kilometers and a lower cloud boundary at 200 meters.

According to eyewitnesses, the aircraft flew over a point 2700 meters northwest (azimuth 307°) of the runway threshold, almost on the landing course with a left turn.

The flight operations supervisor knew that the weather reported by AMSG at 12:15 was below the minimum but did not take action to direct the aircraft to an alternate airport.

The crew then entered clouds in mountainous terrain and decided to attempt a second approach without sufficient conditions for visual flight.

[2] The main cause of the accident was the significant deviation of the aircraft's flight path from the established procedure during the go-around.
