NTSB Factual Report

The pilot started the takeoff roll from runway 21L with a slight crosswind from the left. He indicated that the start of the roll seemed normal, but then the airplane started to drift to the right side of the runway. He started a correction to the left, and the airplane did an abrupt left turn. It then turned sharply back to the right with the tail swinging left. The airplane departed the right side of the runway surface, and the left main landing gear snapped off. The left wing and aileron sustained substantial damage.

NTSB Probable Cause

The pilot's failure to maintain directional control during the takeoff roll, resulting in a runway excursion.
