The 1,000-hour commercial pilot reported that during takeoff roll on runway 01 (a 3,800-foot long and 50-foot wide asphalt runway), the airplane veered to the left, exited the runway, and traveled through a muddy area adjacent to the runway. Subsequently, the right main landing gear collapsed, and the airplane came to rest in an upright position. The pilot reported that the wind was from the west at about 8-10 knots at the time of the accident.
