Aircraft Accident/Incident Report

Baker Lake, Washington 98237
Thursday, February 10, 2011 16:30 PST

NTSB Narrative Summary Released at Completion of Accident

According to the pilot, he performed about 20 touch-and-go practice takeoffs and landings on the dry lake bed prior to the accident. He stated that the terrain was mostly flat, but in places it was uneven and rough. During the last landing, the airplane's wheels became bogged down in the soft terrain, and the propeller struck the ground. The pilot shut down the engine, inspected the propeller, and examined the planned takeoff path for suitability. Thereafter, he attempted to depart. As the airplane accelerated, the left main landing gear encountered an area of soft dirt. The airplane impacted a berm whereupon it nosed over, bending the wing structure and the vertical stabilizer. The pilot further reported that no mechanical malfunction had precipitated the accident.

NTSB Probable Cause Narrative

The pilot's encounter with soft terrain during an attempted takeoff from a dry lake bed.
