Engine plots from the recovered flight-data recorder shows the flame-out warning of the right engine at an altitude of around 1,200 ft was infact false and the right engine had actually shifted into idle mode. As a result the engine propeller feathered.
Seconds later the fuel flow into the left engine was cut off, with no reported stall warnings. The same time, pilot reported engine flame out, according to air traffic communications.
42 seconds later the pilot attempted unsuccesful left engine restarts, which was followed by stall warning.
Sixteen seconds later the flight data recoder stopped, indicating the crash.
The 2014 built ATR 72-600 was powered by two Pratt and Whitney PW127M turboprop engines. The engines were recently replaced.
Modern twin engine aircraft are designed to fly even with a single engine in case of a emergency.
The low speed as a result of the power loss stalled the airplane, leading to the crash.
