## Analysis

THE PILOT HAD JUST PURCHASED THE AIRCRAFT AND WAS MAKING TOUCH AND GO LANDINGS FOR FAMILIARIZATION. HE WAS USING A PAVED RUNWAY WITH PATCHES OF ICE AND WAS LANDING WITH ABOUT A 10 KNOT RIGHT CROSSWIND. ON ABOUT HIS EIGHTH LANDING, THE PLANE BEGAN TO DRIFT TO THE RIGHT. THE PILOT REPORTED THAT HE WAS UNABLE TO CORRECT ENOUGH TO AVOID RUNNING OFF THE RUNWAY. THE PLANE STRUCK A SNOWBANK AND TURNED OVER ON ITS BACK.
