The flight was categorized as scheduled revenue flight and the reported phase was landing (descent or approach) at a airport (less than 10 km from airport) crash site.

The listed crash cause is human factor. The aircraft departed Tehran-Mehrabad Airport at 1815LT with a delay of more than two hours due to poor weather conditions at destination. While descending to Orumiyeh Airport by night, the crew encountered poor weather conditions with snow falls, visibility 800 metres and three ceilings at 1,500, 2,000 and 6,000 feet. After the crew was unable to intercept the ILS, the decision to initiate a go-around procedure was taken. Approaching the stall speed, the stick shaker activated and the aircraft probably encountered icing conditions. In a left bank angle estimated between 26 and 40°, the engine n°3 and 1 failed. At an altitude of 600 feet and at a speed of 96 knots, the flaps were retracted, causing the aircraft to stall and to impact the ground. The aircraft broke in three but there was no fire. 70 passengers and 8 crew members were killed while 27 other occupants were injured, some seriously.

Aircraft reference details include registration EP-IRP, MSN 20945/1048, year of manufacture 1974.

Geospatial coordinates for this crash are approximately 37.5397°, 45.0703°.
