During the takeoff roll from the 1,400-foot-long runway, the airplane encountered water on the runway and "was not able to gain enough momentum." During the initial climb the airplane was unable to clear the surrounding trees. Therefore, the pilot elected to maneuver the airplane in order to avoid striking the trees. During the turn, the airspeed decreased and the pilot made an off airport landing to a nearby golf course. According to a witness, the airplane was about 40 feet off the ground when it began the turn. In addition, it looked like the airplane "turned too tight," and that the "wings never leveled out" prior to impacting the ground. During the off airport landing, the airplane incurred substantial damage to the left wing and fuselage. The pilot reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation. He further stated, "it was my fault, not the [airplane's]." At the time of the accident the winds were from the northwest at 4 knots.
