Read the full NTSB narrative
WHILE DISPENSING A HERBICIDE, 'THE ENGINE LOST POWER, RPM, AND A VIBRATION WAS FELT. THE ENGINE RECOVERED TO FULL POWER CAUSING THE HELICOPTER TO YAW.' THIS EVENT OCCURRED THREE ADDITIONAL TIMES FOR UNDETERMINED REASONS DURING AN ATTEMPTED RUN-ON LANDING TO A FIELD. AS THE HELICOPTER'S SKIDS CONTACTED THE GROUND, THE PILOT HEARD A 'BOOM', THE HELICOPTER YAWED, THE SKIDS SEPARATED FROM THE FUSELAGE, AND THE HELICOPTER CAME TO REST ON ITS SIDE.
