Traffic Control. At the time, the speed had reached its peak speed of 224 km/h before it began to drop. The aircraft then began to stall. Crash was inevitable as the altitude was too low to recover. Final report It was later determined that multiple factors had contributed to the accident. The aircraft was overloaded by , and was not properly trimmed for takeoff. The stabilizer should have been trimmed upwards between zero and six degrees, however the trim setting used during the accident flight was two degrees downwards. The rudder trim had not been centered. The flaps, which were supposed to be set at 15 degrees, were set only at ten degrees. During the takeoff roll, a malfunction in the electronic fuel delivery system caused a loss of power in the right engine. Two seconds later, although rotation speed had not yet been reached, the captain brought the plane into the air. Shortly afterwards, the crew noticed the engine failure but did not immediately attempt to feather the propeller. The plane began to lose airspeed, reaching a maximum height of before descending and eventually entering an aerodynamic stall. By the time the crew feathered the propeller, 17 seconds after the initial failure, it was too late to recover the plane, which impacted a highway from the end of the runway.
