Primary finding
Probable cause
The pilot’s failure to maintain adequate airspeed while maneuvering on final approach which resulted in a high sink rate and subsequent collision with a fence.
Investigator assessment
Analysis narrative
The pilot reported he was on final approach for a short field landing when the airplane developed an unexpected sink rate from which he did not have time to recover. The airplane subsequently struck a fence bordering the runway and impacted the ground, which resulted in substantial damage to the airframe. A witness located on the approach end of the runway reported that the airplane appeared to be low and at an abnormally slow airspeed, and immediately before impact with the fence, the airplane pitched up rapidly. The pilot stated that he got behind the airplane on approach and there were no mechanical malfunctions or failures with the airplane that would have precluded normal operation.
