The pilot's failure to maintain adequate altitude/clearance from rising terrain while maneuvering at a low altitude, which resulted in an in-flight collision with terrain. Factors associated with the accident were a downdraft, the pilot's intentional low altitude flight, and his inadequate weather evaluation.

The pilot's inadvertent stall/mush during the final approach to land. Factors associated with the accident are the pilot's misjudged flare, and the rough and uneven terrain.
