The pilot reported that during the landing roll he realized the airplane was not going stop within the remaining runway distance. He further reported that he aborted the landing and became airborne, but during the initial climb the airplane entered an aerodynamic stall and impacted terrain about 300 feet beyond the runway threshold.
The fuselage and both wings sustained substantial damage.
The pilot reported no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
