Aircraft Accident/Incident Report

White Bear Lake, Minnesota 55110
Tuesady, April 20, 2010 16:01 CDT

NTSB Narrative Summary Released at Completion of Accident

The pilot reported that he conducted a normal preflight, run-up, and takeoff. The engine stopped during the takeoff climb, about 150–200 feet above ground level. The pilot restarted the engine 3–4 times, but the engine was producing less power each time. The engine stopped and the pilot executed a forced landing to a field with trees in it. The airplane sustained substantial damage on impact with trees and terrain. Postaccident inspection of the airplane’s fuel system revealed that the fuel line between the fuel sump (strainer) and the carburetor was full of water. The inspection of the airplane revealed no other anomalies.

NTSB Probable Cause Narrative

A total loss of engine power during takeoff due to fuel contamination as a result of the pilot's inadequate preflight inspection.
