NTSB Narrative Summary Released at Completion of Accident

The commercial certificated pilot was landing a tundra tire-equipped airplane on an asphalt surface runway that was 3,616 feet long and 75 feet wide. The pilot said that during the landing roll, the airplane began to veer left and right, and he added engine power to control the airplane. The pilot indicated that the airplane departed off the runway surface to the right, and then ground looped to the right. The left main landing gear collapsed inward and upward, and the left wingtip struck the ground. The airplane received damage to the left landing gear and fuselage structure, the left wing lift strut, and left wingtip. The pilot reported the wind was from the south-southwest at 5 knots.

NTSB Probable Cause Narrative

The pilot's failure to maintain directional control of the airplane during the landing roll which resulted in an inadvertent ground loop and collapse of the left main landing gear.
