Aircraft Accident/Incident Report

Peoria, Arizona 85381
Tuesady, February 26, 2013 9:30 MST

NTSB Narrative Summary Released at Completion of Accident

The pilot reported that he was practicing touch-and-go landings. The airplaneā€™s engine lost power while on the base leg of the traffic pattern, and the pilot decided to land on a dirt road. He landed uneventfully, but a wing collided with a road sign during the landing roll. The airplane spun off the road into desert terrain and sustained substantial damage to the wing and fuselage. Postaccident examination of the engine revealed a cracked cooling fan housing that likely resulted in misalignment of the magnets in the ignition system, which led to an ignition failure and loss of engine power. The fan housing was not a manufacturer-supplied part.

NTSB Probable Cause Narrative

A cracked cooling fan housing, which led to a malfunction of the ignition system and a loss of engine power during the landing approach.
