## Analysis

THE AIRCRAFT HAD A FULL LOAD OF FUEL AND CHEMICALS ON BOARD FOR THIS TAKEOFF. THE PILOT STATED THAT THE BRAKES LOCKED ON THE TAKEOFF GROUND RUN AND REDUCED THE AIRCRAFTS ACCELERATION. A RAILROAD CROSS TIE BARRIER AT THE END OF THE RUNWAY MADE AN ON GROUND OVER RUN UNDESIRABLE/NOT POSSIBLE. HE LIFTED OFF PREMATURELY, THE AIRCRAFT STALLED AND CRASHED ABOUT ONE HALF MILE FROM THE RUNWAY. THE AIRCRAFT BURNED AFTER GROUND IMPACT.

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.
