Accident Details
While turning from downwind to base leg, the pilot advanced the throttle and experienced a sudden loss of engine power. Unable to reach the runway, the pilot conducted a forced landing in a flat open field located off the approach end of the runway. The initial touchdown was uneventful; however, during the rollout, the aircraft encountered an earthen berm and sustained substantial damage.
Investigation Findings
A post-accident inspection revealed that a significant portion of the carburetor throat was clogged with strips of paint. These paint strips had separated from the induction air inlet channel aft of the air filter. Further inspection of the air inlet channel uncovered other large areas of partially peeled paint.
The aircraft had been repainted approximately four months prior to the accident. According to the aircraft manufacturer, the surface of the inlet channel aft of the filter is not painted during the manufacturing process, and it should not be painted when new paint is applied to the airframe structure.
