Probable cause

The pilot's misjudgement of altitude and distance to the runway, while on final approach, and his failure to attain the proper touchdown point for landing. The fence was a related factor.

Analysis

While on final approach to land at a private grass strip, the aircraft struck a fence post. During impact, most of the right stabilizer & all of the right elevator separated from the aircraft. The aircraft continued flying & the pilot flew it back to the point of departure & landed successfully.
