## Analysis

THE ACFT APPROACH WAS HIGH AND FAST. THE LANDING WAS MADE WITH 500-600 FT OF RUNWAY REMAINING. THE ACFT BRAKES WERE NOT SUFFICIENT TO STOP ON THE RUNWAY. THE PILOT ADDED POWER AND VEERED LEFT OFF THE END OF THE RUNWAY TO AVOID A HEAVILY TRAVELED ROAD, THE AIRCRAFT COLLIDED WITH TREES.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
