Aircraft Accident/Incident Report
San Martin, California 65046
Saturday, April 7, 2007 15:00 PDT
NTSB Narrative Summary Released at Completion of Accident
The pilot reported that he entered the pattern on left base for landing. During the turn from base to final approach, the aircraft was low so the pilot added power, however, the engine did not respond. The pilot realized that he would not make the runway and chose an open field for an off airport landing. During the landing roll, the pilot intentionally ground looped the aircraft to avoid a collision with a fence. The aircraft sustained substantial damage to the right landing gear attach fitting and longeron as well as the right wing tip. After the aircraft was recovered from the field and taken to the airport, the engine was started and found to run without anomaly on the main fuel tank. The pilot reported that after the accident he pulled up the weather current at the time of the accident and compared it to the probable carburetor icing chart, he noted that the temperature and dew point fell into the range of serious icing at glide power. The nearest weather reporting facility indicated a temperature of 70 degrees F. and a dew point of 55 degrees F.
NTSB Probable Cause Narrative
Carburetor icing conditions which resulted in a loss of engine power during the base turn to final approach. The pilot's inadequate preflight planning/preparation for the flight was a factor.
