## Analysis

THE PILOT REPORTED THAT DURING THE TAKEOFF ROLL, A WIND GUST CAUSED THE LEFT WING TO RAISE AND THE AIRPLANE VEERED TO THE RIGHT. HE IMMEDIATELY APPLIED LEFT AILERON AND RUDDER, BUT TO NO AVAIL. THE AIRPLANE WENT OFF THE RUNWAY, HIT A TREE AND FENCE, AND SUBSEQUENTLY CAME TO REST WITH ITS NOSE IN A DRAINED SWIMMING POOL. NO PREIMPACT MECHANICAL MALFUNCTION OR FAILURE WAS REPORTED. THE WIND WAS REPORTED TO BE FROM THE NORTHWEST AT 25 GUSTING 30 KNOTS. THE MAXIMUM DEMONSTRATED CROSSWIND CAPABILITY OF THE AIRPLANE WAS 17 KTS.
