Aircraft: Cessna 180

Defining Event: Loss of control on ground

Flight Conducted Under: Part 91: General Aviation - Personal 

The pilot in the tailwheel-equipped airplane reported that he usually flies with two seat cushions, but he gave one cushion to his passenger. During the takeoff roll on the narrow grass surface private airstrip, he asserted that the missing cushion distorted his visual perception.

Using his peripheral vision, he felt the airplane had drifted to the left, so he applied right rudder and right brake. He recalled that the airplane's left wing struck bushes, but he continued the takeoff. The airplane's tail lifted, and the airplane veered left into the bushes.

Substantial damage was sustained to the right wing.

The pilot reported that there were no mechanical malfunctions or failures with the airplane that would have precluded normal operation.
