The pilot reported that during the takeoff roll from a private, dirt airstrip near Alamosa, Colorado, the Alon A2 encountered a bump and became airborne prematurely.
He attempted to reduce the angle of attack, but the left wing aerodynamically stalled and the airplane hit terrain.
The airplane sustained substantial damage to the fuselage, left wing, right wing and aileron, and right vertical stabilizer.
Probable cause: The pilot’s failure to maintain aircraft control during takeoff on an uneven runway surface, which resulted in it becoming airborne prematurely, an aerodynamic stall, and impact with terrain.

Capt R Bud Fuchs says
The dragging brake accident:
It’s a glaring omission that AILERONES, ADVERSE YAW was not applied to counter the dragging brake.
Ailerons ALWAYS proportionally, opposite the puny, stalled rudder on roll out & take offs.
At least 2Xs the area and twice the leverage of a stalled rudder.
Ailerons have 3 basic chores, and this example is the least understood sample where we are failing our clients.
