Probable cause

The pilot's failure to maintain directional control during the landing roll which resulted in an inadvertent ground loop/swerve.

Sequence of events

NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.

Analysis

The pilot reported that a normal approach to runway 08 was initiated and the wheel landing appeared normal. During the landing roll, the left wing started to dip and the pilot tried to lift the wing with aileron control and the application of the wheel brakes to straighten the ground path. The aircraft immediately veered off the runway and spun around with the left wing making contact with the ground. The pilot thought that the main wheel tire might have been low or flat. Post accident inspection revealed that the tire valve stem was displaced and the tire was flat. The condition of the tire before the accident could not be determined.
