A Learjet 31A was destroyed when it impacted a field near Apaseo el Alto, Mexico. All four occupants were killed.
The aircraft departed Zacatecas at 15:16 hours local time on a flight to Toluca. Last contact with the flight was during the climb to FL380 when the first officer reported turbulence. After reaching FL360 the aircraft entered a high speed descent until it collided with terrain. Investigation showed that the flight crew were in the process of recovering from the loss of control before the aircraft hit the ground.
The cause of the accident could not be established. However, it was considered that the stabilizer trim position had caused flight instability, misinterpreted as turbulence. An extreme nose-up trim could have initiated the loss of control.
Probable Cause: "Loss of control in flight due to undetermined causes due to lack of tests and components having been removed from the site of the accident".
