## Probable cause

The pilot’s failure to maintain adequate airspeed while conducting a go-around and his exceedance of the airplane’s critical angle of attack, which resulted in an aerodynamic stall/spin at too low of an altitude to recover. Contributing to the accident were the pilot’s lack of preflight planning, including his failure to obtain a briefing on the challenging, one-way airstrip, and his unfamiliarity with operating into and out of the airstrip, which was surrounded by mountainous terrain.
