Narrative:
The amateur-built aircraft was substantially damaged during a forced landing following a loss engine power shortly after takeoff. The pilot reported: "After doing a run-up prior to my departure I applied full throttle and departed the runway. Moments later I noticed a loss of power and the engine quit running." The pilot attempted a forced landing on a four-lane roadway adjacent to the airport. The pilot landed on the shoulder of the roadway and proceeded into an adjacent ditch. A post-accident engine examination was conducted and did not find any anomolies. Weather conditions reported in the vicinity of the accident location included an air temperature and dew point of 7 degrees Celsius and -2 degrees Celsuis, respectively. According to data provided by Transport Canada, a possibility of serious carburetor icing at descent power existed at the time of the accident.

Probable Cause: The loss of engine power due to carburetor ice. A contributing factor was the ditch adjacent to the roadway.
