Circumstances:
While descending to Nha Trang Airport, the crew encountered poor weather conditions with limited visibility due to heavy rain falls. On approach, the aircraft deviated from the W13 airway by six km when it struck trees, lost height and crashed on the slope of a mountain located 350 metres, about 33 km southwest of Nha Trang. The wreckage was found eight days later at an altitude of 970 metres. A passenger was seriously injured while 30 other occupants were killed. At the time of the accident, weather conditions were poor due to the presence of typhoon 'Forest' approaching the area.
Probable cause:
Following negligences and wrong interpretation of instrument settings, the aircraft deviated from the prescribed W13 airway by 6 km until it impacted the ground.
