14 CFR Part 91: General Aviation
Accident occurred Wednesday, July 27, 2016 in Alamosa, CO
Probable Cause Approval Date: 08/31/2016
Aircraft: ALON A2, registration: N5690F
Injuries: 1 Uninjured.

NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.

The pilot reported that during the takeoff roll from a private, dirt airstrip the airplane encountered a bump and became airborne prematurely. The pilot further reported that he attempted to reduce the angle of attack, but the left wing aerodynamically stalled and the airplane impacted terrain.

The airplane sustained substantial damage to the fuselage, left wing, right wing and aileron, and right vertical stabilizer.

The pilot reported that there were no preimpact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.

The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
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.
