Accident Overview
A pilot reported losing directional control during takeoff from a grass strip. The pilot stated that while taking off, the aircraft drifted to the left. Due to tall grass, the pilot could no longer distinguish the runway strip from the surrounding field area.
Pilot Actions and Aircraft Response
The pilot applied full right rudder, but the aircraft continued to swerve to the left and would not accelerate above 52 miles per hour. To avoid a 15-foot-high berm, the pilot pulled back on the control yoke. The aircraft flew over the berm and a small pond before stalling.
Additional Factors
The pilot reported being unaware of the effect tall grass has on an aircraft during takeoff and stated an intention to obtain additional instruction on soft-field takeoff procedures. The density altitude was approximately 5,400 feet.
