What happened
Upon landing on runway 15 at Chilpancingo-Doctor Alfonso G. Alarcón Airport, the aircraft lost control during the landing roll. The plane drifted toward the right side of the runway, exiting the paved surface and impacting several mounds of earth. The sequence of events concluded when the aircraft struck a concrete wall, which caused the plane to come to rest in an inverted position.
As a result of the accident, there were 4 fatalities and 14 injuries among the people on board.
Findings
Preliminary reports indicate that the aircraft was traveling at an excessive speed at the moment of touchdown, which contributed to the loss of directional control on the runway.
