Aircraft involved
Probable cause & findings
The loss of engine power due to carburetor icing and the pilot’s failure to utilize carburetor heat.
Factual narrative
The pilot reported that he was departing from a remote unimproved landing site. During takeoff, at about 200 feet above ground level, the engine lost all power. The pilot made a forced landing to a gravel sand bar, which resulted in substantial damage to the fuselage and both wing lift struts. The pilot stated that he believed that the carburetor developed ice as weather conditions were conducive to carburetor icing and he failed to apply carburetor heat. The pilot reported that there were no pre-accident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
