Accident Sequence
The pilot was receiving vectors for spacing around other traffic. After being cleared to land, the aircraft was higher than the traffic pattern altitude. To dissipate the excess altitude, the pilot performed a slip. When the throttle was advanced, the engine did not respond. The pilot conducted an off-airport forced landing. During the landing, the aircraft collided with a curb, a stop sign, a bus sign, and a fence.
Investigation Findings
Following the accident, the engine was functionally tested and operated satisfactorily. An FAA aviation safety inspector offered the opinion that the power loss may have been due to the engine 'loading up.' At the time of the accident, the airport temperature was 33°C (91.4°F) and the dew point was 9°C (48.2°F). According to the Carburetor Icing Probability Curve, light icing at glide and cruise power settings is possible under these conditions.
