From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

Airman was conducting swath runs on a north/south orientation in a cornfield with high tension power lines running diagonally through the field from a southwest to north east direction. The airman had completed approximately six or seven swath runs , flying underneath the powerlines. The airman stated on the next swath run just as he was about to pass underneath the wires that he observed a slight rise in the terrain under the wires. He stated he attempted to miss the wires by flying down into the corn crop, however the wire deflection cable and rudder cap clipped the lower powerline. The aircraft received minor damage to the rudder cap, severed the wire deflection cable and slightly bent the vertical stabilizer spar. The pilot, the sole occupant, received no injuries. The power lines were undamaged
