NTSB Narrative Summary Released at Completion of Accident

The airplane collided with a vehicle during an overrun following an attempted aborted landing during a training flight. The accident occurred on the first landing of the flight. The CFI stated the landing approach was normal and the student landed the airplane "a couple hundred feet past the displaced threshold." He stated the airplane bounced and he instructed the student to initiate a "go around." He stated the student added full power, turned off the carburetor heat, and gradually retracted the flaps. The CFI stated the airplane was not climbing at a rate sufficient enough to clear the 41 foot tall trees at the end of the runway. The CFI stated he took control of the airplane, retarded the throttle, and brought the airplane back to the runway. He stated that once the airplane touched down, he applied heavy braking and the tires locked up. The airplane slid off the end of the runway and onto a road where it contacted a passing car. The student stated he touched down 50 feet past the displaced threshold. Winds were clam at the time of the accident. The Airport/Facility Directory shows the total runway length is 2,582 feet with a 1,089 foot displaced threshold and trees at both ends of the runway.

NTSB Probable Cause Narrative

The pilot's misjudged distance/speed which led to an overrun and collision with a vehicle. Contributing to the accident was the flight instructor's delayed remedial action in executing a go-around.
