While cruising at the altitude of 18,000 feet, the aircraft suffered a hydraulic failure. Some instruments failed and the crew elected to gain height to have a better visibility when shortly later, the right engine backfired and lost power. The captain decided to make an emergency landing but encountered local patches of fog. The aircraft eventually belly landed on a plateau and came to rest. All three crew members were rescued.
Probable cause:
Hydraulic failure for unknown reasons.
