Incident Overview
A pilot reported an engine power loss while maneuvering for landing. The pilot was turning from base to final approach for runway 23 when he reduced power. As he continued the approach, he advanced the throttle, but the engine did not respond. He throttled forward three more times without engine response. The pilot verified that the mixture and carburetor heat controls were properly set.
Sequence of Events
During the approach, the pilot lowered the nose to increase airspeed, intending to flare above power lines in his path. However, the landing gear struck the power lines, and the airplane subsequently descended to the ground. The pilot stated that carburetor heat had been used earlier during the flight and was operational at that time.
Pilot Report
The pilot reported that there were no mechanical malfunctions with the aircraft. The weather conditions at the time included a temperature of 71°F and a dew point of 59°F. According to icing probability charts, these conditions were conducive to carburetor icing.
Investigation Findings
The investigation focused on the reported engine power loss. The pilot's actions included multiple throttle advances and checking engine controls. The absence of mechanical malfunction suggests that the power loss may have been related to environmental factors. The temperature and dew point spread indicated a potential for carburetor icing, which can cause engine power loss in certain conditions.
