Aircraft Accident/Incident Report

Minden, Nebraska 68959
Thursday, June 28, 2012 6:45 CDT

NTSB Narrative Summary Released at Completion of Accident

The pilot reported that during the aerial application flight he made the first pass over a field where the wind was light and variable. He then turned around and flew a pass over a tree line and descended "maybe a little low," where he flew the airplane through the wake turbulence from his previous pass. According to the pilot, the turbulence disrupted the "round out" to the field and the airplane's wheels and left wing contacted the corn. The airplane turned sideways, slid backwards, and its empennage sustained substantial damage when it deformed. The pilot indicated that there were no mechanical malfunctions with the airplane during the flight.

NTSB Probable Cause Narrative

The pilot’s failure to maintain clearance from the wake turbulence from a previous pass.
