Sepahan Airlines Flight 5915 (SPN 5915) was a scheduled domestic passenger flight from Tehran to Tabas, Iran. On 10 August 2014, the HESA IrAn-140 aircraft serving the flight crashed shortly after takeoff from Mehrabad International Airport, falling into a residential area near the Azadi Stadium.[2][3] Of the 42 passengers and six crew on board, 40 people died.[4]

Accident[edit]

The aircraft crashed into a residential block on Mina Glass Boulevard in western Tehran at 09:18 local time (04:48 UTC). The crash resulted in a fire erupting. IRNA, the Iranian state news agency, suggested that the aircraft suffered an engine failure.[5]

Passengers and crew[edit]

There were 42 passengers and a crew of six. Of the 42 passengers, 36 were adults and six were children.[6][4]

Cause[edit]

Fars News Agency quoted Mohammad Ilkhani, head of the Iran Airports Company as stating, "Failure of one of the plane's engines caused the plane to crash on the northern side of the Tehran-Karaj highway [Expressway]."[7] Survivors reported that the number two engine had stopped during the takeoff.[8] The pilots reportedly turned back four minutes after takeoff upon experiencing technical difficulties, but were unable to maintain altitude.[9] The Antonov An-140 (upon which the HESA IrAn-140 is based) is a relatively recent development, with knock-down kits being delivered for domestic Iranian assembly as recently as 2007.[10]

The final investigation reports:[4]

The accident investigation team determined that the main cause of this accident was combination of:
1. Electronic engine control (SAY-2000) failure simultaneously with engine No: 2 shutdown, just about 2 seconds before aircraft lift-off.
2. AFM Confusing performance chart resulted the pilots relying on performance calculation that, significantly over-estimate the aircraft MTOM.
