A HESA IrAn-140 passenger plane, operated by Sepahan Airlines, crashed shortly after takeoff from Tehran-Mehrabad Airport (THR), Iran. According to a statement by the Civil Aviation Organization (CAO), there were 40 passengers and 8 crew members on board. FARS news agency reported nine occupants survived.

The airplane took off from runway 29L at Mehrabad Airport. Instead of performing the left hand procedure turn after takeoff, the airplane banked right and lost altitude. It impacted the ground, broke up and burst into flames. Takeoff was accomplished with a tailwind component of approximately 6 knots, according to weather reports.
Officials reported that the right hand engine failed and that the airplane was overloaded for the prevailing temperature. A preliminary report quoted non-compliance with instructions for calculating the weight of cargo and passengers as a factor, along with the wrongly calculated VR speed.

The IrAn-140 is an Antonov 140 turboprop aircraft, built under license by HESA in Iran. Sepahan Air, which is a division of HESA, operated six IrAn-140's.
