NTSB Narrative Summary Released at Completion of Accident

THE PILOT SAID HE WAS PERFORMING TOUCH-AND-GO PATTERN OPERATIONS AND THE ENGINE LOST POWER SHORTLY AFTER LIFT-OFF ON RUNWAY 29R. THE PILOT LANDED ON THE RUNWAY, BUT HAD INSUFFICIENT PAVEMENT REMAINING TO STOP THE AIRCRAFT. THE AIRCRAFT OVERRAN THE END OF THE RUNWAY AND NOSED OVER WHEN SOFT, RECENTLY PLOWED DIRT WAS ENCOUNTERED. THE PILOT REPORTED THAT HE EXAMINED THE ENGINE COMPARTMENT AND FOUND THE DUCT HOSE FROM THE HEAT BOX TO THE CARBURETOR CRIMPED, BLOCKING HOT AIR FLOW TO THE CARBURETOR. THE ENGINE WAS EXAMINED WITH NO DISCREPANCIES NOTED. THE PILOT SUSPECTED CARBURETOR ICE AS THE CAUSE OF THE ENGINE POWER LOSS. THE TEMPERATURE AND DEW POINT AT THE AIRPORT WERE 58 AND 51 DEGREES, RESPECTIVELY. REVIEW OF A CARBURETOR ICING PROBABILITY CHART REVEALED THAT THE NOTED TEMPERATURES WERE WITHIN AN AREA OF THE CHART ANNOTATED 'SERIOUS ICING -- CRUISE OR CLIMB POWER.'

NTSB Probable Cause Narrative

A blockage in the carburetor heat air duct which limited the effectiveness of the system's ability to prevent the formation of carburetor ice and resulted in a loss of power. A factor in the accident was the soft nature of the recently plowed ground in the runway overrun area.
