## Probable cause

The pilot’s decision to conduct a steep departure at a high-density altitude and the exceedance of the airplane’s critical angle of attack during a climb, which resulted in an accelerated stall and subsequent loss of control. Contributing to the accident was the installation of a high pitch angle propeller that was not designed for the installed engine which likely degraded the airplane’s performance.
