Probable cause

The pilot's failure to maintain a proper descent rate. Contributing to the accident was the rising terrain and the tailwind condition.

Analysis

The pilot stated that an airplane on the ground reported the wind to be from the north at 8 knots. During the final approach, the airplane began to sink at a higher than desired sink rate. The pilot applied power, but the airplane bounced three times. On the third bounce he added full power and attempted a go around into rising terrain. The tail of the airplane struck some brush and then the left wing struck a tree and the pilot aborted the go around. They were landing to the north into rising terrain and the airplane's angle of climb was equal to the angle of the rising terrain. The pilot stated that once on the ground he noticed that the wind was from the south.
