Probable cause
The pilot’s failure to maintain directional control during the landing roll, as a result of a flat left main landing gear tire.
NTSB analysis
According to the pilot, when the airplane touched down on the runway, he felt a vibration followed by the airplane pulling to the left. The pilot added right brake in attempt to realign the airplane; however, it continued to the left and exited the left side of the runway. The airplane traversed over the gravel adjacent to the runway and into brush, where it came to rest. A postaccident examination of the airplane revealed that the airplane’s left main landing gear tire was flat. No other anomalies were noted that would have precluded normal flight.
