The pilot's premature retraction of the wing flaps and his subsequent failure to maintain pitch control during an attempted go-around, which resulted in the airplane exceeding its critical angle-of-attack and an aerodynamic stall. Contributing to the accident were the pilot’s inadequate in-flight fuel planning; his internal pressure to reach the airport expediently due to low fuel, which led to a high and fast approach; and his subsequent decision to go around when low on fuel.
