Accident Details

The accident occurred during takeoff from a private airstrip. The pilot was departing toward the south and had just reached lift-off airspeed.

Sequence of Events

As the aircraft accelerated, both the pilot and passenger noticed an unidentified object running across the runway under the main wheels. The pilot believed the object was either a dog or a child. In an attempt to avoid hitting the object, the pilot abruptly pulled the control stick aft. At the same time, the passenger depressed the right rudder pedal. These simultaneous control inputs caused the right wing to strike the runway surface.

Outcome

Following the wing strike, the aircraft ground looped and nosed over.
