This October 2007 accident report is provided by the National Transportation Safety Board. Published as an educational tool, it is intended to help pilots learn from the misfortunes of others.
Aircraft: Piper Super Cub.
Location: Crowley Ranch, Ore.
Injuries: 1 Fatal.
Aircraft damage: Destroyed.
What reportedly happened: The pilot was using the airplane to herd cattle. A witness told investigators the pilot dove the airplane over the herd, then pulled up sharply. He did this twice, then initiated a 360° turn. After completing the turn, with the wings level, the airplane hit a series of power transmission lines that were in its flight path. The airplane then hit the ground.
The post-accident examination of the airframe and engine revealed no evidence of a mechanical malfunction or failure prior to impact.
Probable cause: The pilot’s failure to maintain adequate clearance from power transmission lines while maneuvering. The pilot’s diverted attention and decision to maneuver at a low altitude were factors.
