Incident Overview
A pilot was conducting touch-and-go pattern operations at an airport. Shortly after lifting off from runway 29R, the engine lost power. The pilot executed a landing on the same runway but determined that insufficient pavement remained to bring the aircraft to a stop. The aircraft subsequently overran the end of the runway and nosed over upon encountering soft, recently plowed dirt.
Pilot Actions
Following the incident, the pilot examined the engine compartment. He discovered that the duct hose from the heat box to the carburetor was crimped, which blocked the flow of hot air to the carburetor. The pilot suspected that carburetor ice caused the engine power loss.
Post-Incident Findings
An examination of the engine revealed no discrepancies. The crimped duct hose was identified as the only anomaly in the engine compartment.
Weather Conditions
The temperature at the airport was 58°F with a dew point of 51°F. A review of a carburetor icing probability chart indicated that these conditions fell within an area marked 'SERIOUS ICING -- CRUISE OR CLIMB POWER.'
