An aircraft impacted the terrain shortly after takeoff from runway 15 at Toluca International Airport in Mexico. The airplane was partially consumed by the post-impact fire and two pilots experienced fatal injuries during takeoff. The flight crew received a warning about engine thrust reverser deployment at a speed above V1, and continued takeoff despite this. During initial climb, the flight crew inadvertently deployed the drag chute, resulting in a left bank and loss of control. The aircraft collapsed due to low speed and abrupt maneuvers and turns towards the engine side in idle position. The probable cause was a loss of control resulting from the deployment of the reverse of the engine number one during the take-off run above V1, consistent with training and standard operating procedures, leading to the collapse of the aircraft.An aircraft impacted the terrain shortly after takeoff from runway 15 at Toluca International Airport in Mexico.
