Analysis

During a landing, the plt encountered a porpoise which increased in severity. He added full power, raised the nose & initiated a go-around, during which, the stall warning horn sounded. The plt reported that he left the carburetor heat on & left the flaps in a 2/3 exteneded postion. As he continued the go-around, he manuevered the acft to avoid hitting a pole. Immediately thereafter, the left wing tip struck snow covered ground & the acft cartwheeled to a stop. The elevation of the arpt was 6202 ft. the plt had recently received his private plt certificate & had just checked out in this make & model of acft.
