After a normal takeoff roll from runway 29R at Tehran-Mehrabad Airport, the pilot-in-command pulled on the control column and started the rotation when one of the engine failed. Control was lost and the aircraft crashed, bursting into flames. Three passengers were seriously injured while 35 other occupants were killed. All three survivors died from their injuries few hours after the accident.

While approaching Orūmīyeh Airport, the crew contacted ATC and reported technical problems with the landing gear. They seemed to be down but the three green lights did not came on in the cockpit panel. In accordance with ATC, the crew completed a low pass in front of the control tower then initiated a circuit when both engines flamed out. The aircraft went out of control and crashed in a field located 12 km from Orūmīyeh Airport. The aircraft was destroyed and all 11 occupants were killed, among them General Ahmad Kazemi, Chief Commander of the Revolutionary Guard Land Forces and Commander Hanif, Head of the Land Forces intelligence services.

The four engine aircraft departed Zahedan on a flight to Kerman, carrying 257 passengers and a crew of 18, most of them members of the Revolutionary Guards. On board were also several high ranking officers who just conducted a visit of the province of Zahedan, taking part to a narcotic control program. While descending to Kerman Airport by night, the crew encountered poor weather conditions with heavy snow falls and strong winds. On approach, the aircraft struck the slope of Mt Sirach located 32 km from the airport. First rescuers arrived on the scene the next morning. The wreckage was found about 100 metres below the summit and all 275 occupants have been killed.

Few minutes after takeoff from Mashhad Airport, while flying at FL230 about 80 km from his departure point, the crew encountered technical problems when the autopilot system disengaged and the engine n°4 caught fire. The crew elected to extinguish the fire but without success and was cleared to return to Mashhad for an emergency landing. The fire spread to the right wing and the engine n°4 detached. Nevertheless, the crew was able to land safely at Mashhad Airport 24 minutes later and stopped the airplane on the runway. All 230 occupants escaped uninjured while the aircraft was partially destroyed after the right wing broke off and fell on the ground.
