Initial Flight and Engine Irregularity
Before departure, the pilot conducted a visual check of the fuel levels. Approximately one hour into the flight, while cruising at 4,500 feet, the engine began to run rough. The pilot responded by applying full mixture and moving the fuel selector to the right tank, after which the engine resumed normal operation.
Communication and Diversion Plan
The pilot notified Cairns Approach Control of the engine problem and stated his intention to divert to Andalusia.
Secondary Failure and Forced Landing
Shortly thereafter, the engine failed again. The pilot attempted to restart the engine but was unsuccessful. He then executed a forced landing in a plowed field. During the landing, the aircraft struck a furrow, causing the nose gear to detach and the firewall to bend aft.
Post-Incident Inspection
A post-accident examination found no fuel in either fuel tank, and the carburetor was dry. The integrity of the fuel tanks was intact, with no breaches detected.
Probable Cause
No probable cause was provided in the available information.
