What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
The accident flight began at 1610PST conducting left hand traffic on runway 9 at cxp. The crew conducted two straight in autorotation?s without incident. The next pattern consisted of the co-pilot conducting a stuck pedal scenario. This resulted in the PIC calling for a go around and the pilot asked the PIC for a demonstration. The PIC took the controls and set up for the simulated emergency procedure of a stuck pedal condition (right pedal). As the helicopter came over the intended taxiway with a heading 40 degrees to the right of the runway heading the pilot on the controls reduced the throttle to bring the nose of the helicopter into runway alignment for touchdown. The helicopter yawed left 20 degrees and made unanticipated contact with the ground. The helicopter became airborne after contact and began a rapid right uncorrected yaw completing approximately 1 ¾ right rotations where the helicopter drifted to the right off of the runway making contact with the ground on the left skid that induced dynamic rollover to the left. The helicopter slid backwards coming to a rest on a heading of 350 on its left side in the drainage ditch. The crew exited the helicopter after performing an emergency engine shutdown and egressed through the left side cockpit window.
The crew was wearing military CWU/27P nomex flight suites, gloves and flight helmets.
The crew did not sustain any noted injuries in the accident/post-accident sequence.
As the FAA filed it
THE ACCIDENT FLIGHT BEGAN AT 1610PST CONDUCTING LEFT HAND TRAFFIC ON RUNWAY 9 AT CXP. THE CREW CONDUCTED TWO STRAIGHT IN AUTOROTATION?S WITHOUT INCIDENT. THE NEXT PATTERN CONSISTED OF THE CO-PILOT CONDUCTING A STUCK PEDAL SCENARIO. THIS RESULTED IN THE PIC CALLING FOR A GO AROUND AND THE PILOT ASKED THE PIC FOR A DEMONSTRATION. THE PIC TOOK THE CONTROLS AND SET UP FOR THE SIMULATED EMERGENCY PROCEDURE OF A STUCK PEDAL CONDITION (RIGHT PEDAL). AS THE HELICOPTER CAME OVER THE INTENDED TAXIWAY WITH A HEADING 40 DEGREES TO THE RIGHT OF THE RUNWAY HEADING THE PILOT ON THE CONTROLS REDUCED THE THROTTLE TO BRING THE NOSE OF THE HELICOPTER INTO RUNWAY ALIGNMENT FOR TOUCHDOWN. THE HELICOPTER YAWED LEFT 20 DEGREES AND MADE UNANTICIPATED CONTACT WITH THE GROUND. THE HELICOPTER BECAME AIRBORNE AFTER CONTACT AND BEGAN A RAPID RIGHT UNCORRECTED YAW COMPLETING APPROXIMATELY 1 ¾ RIGHT ROTATIONS WHERE THE HELICOPTER DRIFTED TO THE RIGHT OFF OF THE RUNWAY MAKING CONTACT WITH THE GROUND ON THE LEFT SKID THAT INDUCED DYNAMIC ROLLOVER TO THE LEFT. THE HELICOPTER SLID BACKWARDS COMING TO A REST ON A HEADING OF 350 ON ITS LEFT SIDE IN THE DRAINAGE DITCH. THE CREW EXITED THE HELICOPTER AFTER PERFORMING AN EMERGENCY ENGINE SHUTDOWN AND EGRESSED THROUGH THE LEFT SIDE COCKPIT WINDOW.
THE CREW WAS WEARING MILITARY CWU/27P NOMEX FLIGHT SUITES, GLOVES AND FLIGHT HELMETS.
THE CREW DID NOT SUSTAIN ANY NOTED INJURIES IN THE ACCIDENT/POST-ACCIDENT SEQUENCE.
