As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

UPON LANDING NEAR AGRICULTURE TENDER TRAILER, PILOT LOWERED THE SKIDS TO THE GROUND, LOWERED COLLECTIVE AND REDUCED POWER. AS THE ROTOR BLADES STARTED TO DROOP, THEY CAME IN CONTACT WITH THE TENDER TRAILER CAUSING THE AIRCRAFT TO SHAKE AGGRESSIVELY AND TAIL ROTOR TO CONTACT THE GROUND. PILOT ATTEMPTED TO SECURE THE AIRCRAFT BY TURNING OF THE MAGNETOS SWITCHES TO THE OFF POSITION AND MOVING THE MIXTURE CONTROL TO IDLE CUT OFF. WITH NEGATIVE RESULTS, THE PILOT EXITED THE AIRCRAFT AND THEN REENTERED TO SHUT THE FUEL FIREWALL SHUTOFF. WITHIN 35 SECONDS, THE ENGINE STOPPED.
