Forty people are killed when Sepahan Airlines Flight 5915 crashes at Tehran's Mehrabad Airport.
Sepahan Airlines Flight 5915 was a scheduled domestic passenger flight from Iranian capital Tehran Mehrabad International Airport to Tabas, South Khorasan Province, Iran. On 10 August 2014, the HESA IrAn-140 twin turboprop serving the flight crashed shortly after takeoff from Mehrabad International Airport, falling into a boulevard near the Azadi Stadium. Of the 42 passengers and six crew on board, 40 people died.Iran's Civil Aviation Organization mainly attributed the crash to mechanical error. The aircraft suffered a malfunction on one of its engines shortly after take-off. Mismanagement of the emergency by the crew caused the aircraft to lose altitude rapidly, causing it to crash onto a boulevard. Subsequently, investigators also blamed the confusing Aircraft Flight Manual (AFM) that caused the crew to over-estimate the maximum take-off weight.
