Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

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.

Factual narrative

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 (agl). The pilot restarted the engine 3 – 4 times, but the engine was producing less power each time. With the engine stopped, the pilot executed a forced landing to a field with trees in it. The airplane sustained substantial damage on impact with trees and terrain. The 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.
