What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
The flight instructor reported that he asked the pilot receiving instruction to demonstrate a run-on landing on the sod between the runway and taxiway. He reported that as the helicopter touched down at about 25 miles per hour (21.72 knots), the pilot lowered the collective to the full down position while the helicopter was still moving forward with considerable momentum. The helicopter began to "lurch forward" and the nose of the helicopter started to lower. The flight instructor then came on the flight controls, but the helicopter had progressed to an "extreme nose low attitude," and he applied aft cyclic to prevent the main rotor blades from impacting terrain. The main rotor blades instead impacted and separated the tailboom. The fuselage continued moving forward and the nose impacted terrain and then settled back on the skids. The helicopter sustained substantial damage to the fuselage, main rotor system, tailboom, and tail rotor system.
As the FAA filed it
THE FLIGHT INSTRUCTOR REPORTED THAT HE ASKED THE PILOT RECEIVING INSTRUCTION TO DEMONSTRATE A RUN-ON LANDING ON THE SOD BETWEEN THE RUNWAY AND TAXIWAY. HE REPORTED THAT AS THE HELICOPTER TOUCHED DOWN AT ABOUT 25 MILES PER HOUR (21.72 KNOTS), THE PILOT LOWERED THE COLLECTIVE TO THE FULL DOWN POSITION WHILE THE HELICOPTER WAS STILL MOVING FORWARD WITH CONSIDERABLE MOMENTUM. THE HELICOPTER BEGAN TO "LURCH FORWARD" AND THE NOSE OF THE HELICOPTER STARTED TO LOWER. THE FLIGHT INSTRUCTOR THEN CAME ON THE FLIGHT CONTROLS, BUT THE HELICOPTER HAD PROGRESSED TO AN "EXTREME NOSE LOW ATTITUDE," AND HE APPLIED AFT CYCLIC TO PREVENT THE MAIN ROTOR BLADES FROM IMPACTING TERRAIN. THE MAIN ROTOR BLADES INSTEAD IMPACTED AND SEPARATED THE TAILBOOM. THE FUSELAGE CONTINUED MOVING FORWARD AND THE NOSE IMPACTED TERRAIN AND THEN SETTLED BACK ON THE SKIDS. THE HELICOPTER SUSTAINED SUBSTANTIAL DAMAGE TO THE FUSELAGE, MAIN ROTOR SYSTEM, TAILBOOM, AND TAIL ROTOR SYSTEM.
