Probable cause

Failure of the pilot in command to adequately preflight the aircraft resulting in a front cockpit seat cushion interfering with the rudder pedals and brakes.

Analysis

The pvt plt said that during the takeoff roll of the homebuilt acft, the plane veered to the left. The plt was unable to directionally control the acft, and it veered off the runway and rolled over. Post accident investigation revealed the front seat cushion, of the open cockpit tandem seated acft, had fallen to the cockpit floor causing a restriction of the front passenger's brake pedals. The front cockpit had a cover over it making it inconvenient to visually inspect it during the preflight.
