What happened
The pilot initiated a normal approach to runway 08, and the initial wheel landing appeared to be normal. However, during the landing roll, the left wing began to dip. The pilot attempted to correct the movement using aileron control and by applying the wheel brakes to straighten the aircraft's ground path. Despite these efforts, the aircraft immediately veered off the runway and spun around, causing the left wing to make contact with the ground.
The investigation
Following the accident, an inspection of the aircraft was conducted. This examination revealed that the tire valve stem had been displaced and the tire was flat. Investigators were unable to determine the condition of the tire prior to the accident.
