Incident Summary
During initial climb following a touch-and-go, the aircraft's engine lost power. The pilot executed a landing on the remaining runway, but the aircraft departed the runway end and came to rest in a ditch.
Pilot Report
The pilot stated that at approximately 100 feet above ground level, the engine "suddenly stopped running."
Aircraft Manual
An instruction manual for the aircraft describes the carburetor air heat system: when the throttle is fully closed, carburetor air heat is applied automatically through a linkage connected with the throttle arm. From half throttle to full throttle, cold air is fed automatically to the engine. A manual control is also provided and can be used to keep hot air feeding to the carburetor at more than half throttle setting when icing conditions prevail.
Postaccident Examination
A postaccident examination of the aircraft and engine failed to reveal any preexisting anomalies.
Weather and Carburetor Icing Information
A weather report for the accident airport recorded a temperature of 14 degrees Celsius and a dewpoint of 14 degrees Celsius. A carburetor icing probability chart from Transport Canada indicates that a temperature of 14 degrees Celsius, and a dewpoint of 14 degrees Celsius, is in the range of serious carburetor icing potential at any power setting. A Federal Aviation Administration Advisory Circular states that "the effect of throttle icing is a progressive decline in the power delivered by the engine."
