Sepahan Airlines Flight 5915 (August 10, 2014)

Date: August 10, 2014
Passengers: 42
Crew: 6
Fatalities: 40
Cause: "1. Electronic engine control (SAY-2000) failure simultaneously with engine No. 2 shutdown, just about two seconds before aircraft lift-off --- 2. AFM confusing performance chart resulting in the pilots relying on performance calculation that significantly over-estimated the aircraft MTOM."
