After contacting the Ilaga Flight Information Services Officer (FISO), the pilot was advised of calm wind, ground fog on left base and final for runway 25, and visibility of 3 to 4 km. The pilot joined left downwind, selected full flaps, and turned left base at 9,000 feet. At approximately 3 nautical miles from the runway threshold, the pilot reported final and was informed the runway was clear.

The aircraft continued to the right, veered off the runway, and the right wing tip struck a slope at the edge of the runway shoulder, which was higher than the runway elevation. The aircraft's heading changed by approximately 45 degrees, and it came to rest about 20 meters to the right of the runway pavement.
