What happened
During the ground roll for takeoff, the pilot raised the tail of the aircraft before the right side of the plane began to sink. This movement caused the main landing gear to break away from the aircraft, resulting in the plane veering off to the left side of the runway.
An FAA inspector examined the airstrip and identified a mud hole located on the runway at the exact point where the tail wheel would have been lifted off the ground. The inspection suggested that the pilot steered too close to this soft spot, causing the right main landing gear to travel into the mud hole.
