Analysis

The private pilot elected to abort the takeoff attempt from an abandoned roadway too late to stop in time to avoid going into brush and small trees. He said he decided against the takeoff at about the mid-point in the 4000 foot gravel section of the road. The brakes caused the wheels to slide and he was not able to stop in the remaining one-quarter mile.
