- Date: August 10, 2014
- Aircraft: HESA IrAn-140-100
- Location: Tehran-Mehrabad, Tehran City District, Iran
- Fatalities: 40
- Phase of flight: Takeoff and climb
- Cause: Iran CAO: a faulty engine control unit temporarily malfunctioned, shutting down engine No 2 about 2 seconds before liftoff. Contributing factors were an unclear flight manual performance chart that led the crew to overestimate maximum takeoff weight, the failure to feather the failed engine propeller promptly and an overloaded takeoff.
Shortly after takeoff from Tehran Mehrabad on a scheduled flight to Tabas, the HESA IrAn 140 registered EP GPA lost power from its No 2 engine about 2 seconds before liftoff and crashed near the airport. The aircraft was destroyed by impact forces and a post crash fire, and 40 of the 48 people on board died, including all six crew. The Iranian Civil Aviation Organization found that a temporary engine control fault, an overestimated takeoff weight and crew actions including a late propeller feathering were the main factors.
