Probable cause
A partial loss of engine power for undetermined reasons and the pilot's failure to maintain clearance from a power line.
Findings · 3
NTSB’s coded findings. Those marked are part of the probable cause; the rest are factors or other findings. Under each, the cases with the same finding.
Sequence of events
The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.
Analysis
The pilot reported that while practicing ground reference maneuvers the airplane's engine had what he described as a temporary partial loss of power. The pilot was flying back to the airport when the nose landing gear struck a power line. The pilot continued the flight back to the airport. When he attempted to land, the nose landing gear collapsed aft, substantially damaging the firewall. While review of the carburetor icing probability chart revealed that the weather conditions during the flight--a temperature of 26 degrees Celsius and a dew point of 6 degrees Celsius--were conducive to light icing during glide and cruise power, the investigation was unable to determine a cause for the reported power loss.
