Analysis

The student pilot said she was practicing soft field takeoffs and landings during the solo instructional session. Ground witnesses at the airport reported that the aircraft achieved a very steep climb angle after rotation for the takeoff initial climb. The aircraft then began drifting to the left in a nose high descent attitude and the left wing collided with a tree on a golf course adjacent to the airport. The aircraft was examined by FAA airworthiness inspectors. Control system continuity was established throughout the aircraft. No abnormal system conditions were noted during the examination. The rudder trim control was found positioned at about 50 percent to the left.
