Show Low Regional Airport
Aircraft Accident/Incident Report

Show Low, Arizona 85901
Saturday, September 10, 2011 7:55 MST

NTSB Narrative Summary Released at Completion of Accident

The pilot reported that, after touchdown, the airplane immediately turned hard right and that he then applied engine power. The airplane subsequently exited the runway while still turning right and came to rest on its left side. A postaccident examination of the airplane and the braking system revealed no preimpact mechanical malfunctions or failures that would have precluded normal operation.

NTSB Probable Cause Narrative

The pilot’s failure to maintain directional control during the landing, which resulted in a ground loop.
