Analysis

The acft began to lose power at 700 ft MSL during climbout. The pilot tried the boost pumps and was able to regain some power momentarily. When all power was lost the pilot was forced to land short of the airport on a frozen river. The rough ice sheared the nose gear during roll-out. The pilot stated in an interview that he was unaware of trapped water in fuel tanks and he did not drain the fuel sumps during pre-flight.
