During takeoff from a remote private ranch strip, the pilot noticed brush on the runway but deemed it non-threatening. The left main gear struck the debris, causing loss of control and a nose-over accident.

What happened

The incident occurred during the takeoff phase at a remote private ranch airstrip. As the aircraft was preparing for departure, the pilot observed a quantity of brush lying on the runway surface. Despite this observation, the pilot determined that the debris would not constitute an obstacle to the intended flight path and chose not to clear it from the runway.

During the acceleration roll for takeoff, the left main landing gear made contact with the accumulated brush. This impact caused the pilot to lose control of the aircraft. The airplane veered off the side of the runway and subsequently nosed over.

Findings

The primary factor contributing to this accident was the pilot's decision to proceed with takeoff despite visible debris on the runway. The failure to remove or avoid the brush resulted in a gear strike, which directly led to the loss of directional control and the subsequent nose-over damage.

Probable cause

The pilot's failure to clear the runway of debris prior to takeoff, which resulted in the left main gear striking the brush and causing a loss of control.
