Narrative:
THE PLT WAS DEMONSTRATING SKI LANDINGS ON RIVER ICE. THE OAT WAS AT LEAST MINUS 20 DEG F. AFTER A PROLONGED POWER-OFF DESCENT HE RECOGNIZED A NEED FOR ADDITIONAL POWER BUT THE ENG WOULD NOT RESPOND. THE PLT ATTEMPTED TO STRETCH HIS GLIDE BUT THE ACFT STALLED & THE RIGHT SKI-GEAR COLLAPSED. THE PLT LATER STATED HE HAD NOT CONSIDERED THE EFFECT OF THE EXTREME COLD ON THE NON-WINTERIZED ENG. HE COULD NOT RECALL HAVING THE CARB HEAT CONTROL ON, NOR DID HE KNOW THAT THE HEAT WAS REQUIRED TO PRECLUDE A TOO-LEAN MIXTURE FOR THIS ENG.
