Accident Overview

The pilot then realized that the flaps had not been retracted when takeoff power was applied. He retracted the flaps and reduced engine power, then attempted to abort the takeoff. Despite these actions, the airplane veered off the left side of the runway, struck an embankment, and nosed over, coming to rest inverted.
