Aircraft Accident/Incident Report

Crowley Ranch, Oregon 97911
Wednesday, October 3, 2007 14:10 PDT

NTSB Narrative Summary Released at Completion of Accident

According to witnesses near the accident site, the pilot was maneuvering the airplane while herding cattle when the accident occurred. A witness reported that he observed the airplane "...dive down at the cows and then pull up at a pretty sharp angle." The witness stated this occurred twice, and after the second maneuver, the pilot initiated a 360 degree turn. After completing the turn, with the wings level, the airplane collided with a series of power transmission lines that were located at the pilot's 12 o'clock position. The airplane subsequently collided with terrain. Postaccident examination and teardown of the airframe and engine revealed no evidence of a mechanical malfunction or failure prior to impact.

NTSB Probable Cause Narrative

The pilot's failure to maintain adequate clearance from a power transmission line while maneuvering. Contributing to this accident was the pilot's diverted attention, and decision to maneuver at a low altitude.
