Probable cause
The pilot's failure to maintain directional control during the landing roll, which resulted in a runway excursion and separation of the left main landing gear.
NTSB analysis
During the landing roll, the airplane began to swerve to the left and continued off the runway, after which the left main landing gear assembly separated from the airplane. Examination revealed substantial damage to the left wing and horizontal stabilizer.
The pilot did not provide a written statement, nor did he complete the NTSB Pilot/Operator Aircraft Accident/Incident Report Form 6120.1; therefore, the pilot's flight experience and the airplane's maintenance history could not be determined. The accident is consistent with the pilot's failure to maintain directional control during the landing roll.
