Aircraft Accident/Incident Report

Spanish Fork, Utah 84660
Thursday, September 12, 2013 14:30 MDT

NTSB Narrative Summary Released at Completion of Accident

The pilot reported that on the day of the accident, he elected to fly with a light, and slightly uneven, load of fuel to accommodate for the extra equipment and people onboard. During the low altitude flight, the pilot was not transferring fuel from the right wing fuel tanks to the left wing fuel tanks. Subsequently, the left wing fuel tanks ran empty and the forward engine lost power. The pilot elected to land in a nearby corn field. During the landing, the airplane's forward engine firewall sustained substantial damage. The pilot reported no preimpact mechanical failures or malfunctions with the airframe or engines that would have precluded normal operation.

NTSB Probable Cause Narrative

The pilot's failure to properly manage fuel which resulted in fuel exhaustion and subsequent loss of power to the forward engine.
