## Analysis

THE TURF RWY WAS WET FROM RECENT RAINS. THE PLT STATED THAT DURING TAKEOFF, THE ACFT HAD ACCELERATED TO NEAR THE ROTATION SPEED WHEN IT WAS SLOWED BY A SOFT SPOT IN THE RWY NEAR MID FIELD. AT THE SAME POINT, AN UPSLOPE PORTION OF THE RWY WAS ENCOUNTERED & THE ACFT WAS SLOW TO ACCELERATE. AS THE ACFT NEARED THE END OF THE RWY, LIFT-OFF SPEED HAD NOT BEEN REACHED, SO THE PLT INITIATED AN ABORT. THE ACFT CONTINUED OFF THE END OF THE RWY, CROSSED A ROAD & A DRAINAGE DITCH, THEN CAME TO REST IN A BEAN FIELD. THIS RESULTED IN SEPARATION OF THE GEAR & DAMAGE TO THE ENG MOUNTS & LEFT WING SPAR. THE PLT SPECULATED THAT THE RIGHT, FRONT SEAT, PASSENGER MAY HAVE ENADVERTENTLY BEEN RIDING THE BRAKES DURING THE LATTER PART OF THE TAKEOFF ROLL WHICH WOULD HAVE CONTRIBUTED TO THE SLOW RATE OF ACCELERATION.

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.
