Aircraft Accident/Incident Report

Lonsdale, Minnesota 55046
Sunday, October 10, 2010 14:15 CDT

NTSB Narrative Summary Released at Completion of Accident

The pilot reported that he departed from his private airstrip with a passenger for a local flight. Upon returning for landing, his neighbor was operating a combine harvester in a soybean field near the runway threshold. The pilot extended his traffic pattern to allow time for the machine to move out of the runway approach path. However, upon turning back toward the runway, the machine had not moved as far as he had expected. The pilot stated that at that point the airplane struck a power line. It subsequently came to rest upside down and was destroyed during the accident sequence. The pilot stated that there were no failures or malfunctions associated with the airplane prior to the accident.

NTSB Probable Cause Narrative

The pilot's failure to maintain clearance from a power line while on approach to land.
