Aircraft Accident/Incident Report

Plum City, Wisconsin 54761
Sunday, September 5, 2010 8:45 CDT

NTSB Narrative Summary Released at Completion of Accident

According to the pilot, he departed with approximately 10 gallons of fuel onboard the experimental amateur-built airplane. About 20 minutes into the cross-country flight, the airplane's engine lost power and the pilot performed a forced landing to rolling terrain. A postaccident examination of the airplane and engine revealed no mechanical malfunctions or failures that would have precluded normal operation. Additionally, the on-scene inspection revealed that the fuel system was intact and that the fuel sight gauge indicated that the fuel level was low.

NTSB Probable Cause Narrative

The pilot’s improper fuel planning, which resulted in a loss of engine power due to fuel exhaustion.
