## Narrative

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

(-23) THE PILOT STATED THAT HE HAD BEEN PRACTICING TAKEOFFS AND LANDINGS IN THE PIRU PRACTICE AREA ON THE RIVER BED WHEN THE ACCIDENT OCCURRED. HE STATED THAT HE HAD LANDED AND THEN LIFTED OFF AND TAXIED TO THE RIGHT, POSITIONING FOR THE NEXT TAKEOFF. WHILE MOVING TO THE RIGHT, THE RIGHT SKID CONTACTED WET SAND, DUG IN AND CAUSED THE HELICOPTER TO TIP TO THE RIGHT. THE PILOT STATED THAT HE APPLIED LEFT CYCLIC AND THEN MADE THE MISTAKE OF INCREASING COLLECTIVE IN AN ATTEMPT TO CLEAR THE OBSTRUCTION. THE HELICOPTER THEN ROLLED OVER AND IMPACTED THE GROUND ON IT'S RIGHT SIDE. THE PILOT STATED THAT HE THEN SHUT THE ENGINE DOWN, TURNED OFF THE FUEL SELECTOR VALVE AND EXITED THE HELICOPTER. AN ON-SITE EXAMINATION OF THE WRECKAGE SUPPORTED THE PILOTS STATEMENTS. THE HELICOPTER WAS FOUND RESTING ON IT'S RIGHT SIDE. THE RIGHT SKID WAS FOUND EMBEDDED IN THE SAND. THE ROTOR BLADES EXHIBITED DAMAGE CONSISTENT WITH GROUND CONTACT DUE TO DYNAMIC ROLLOVER. THE TAIL ROTOR AND VERTICAL STABILIZERS, AS WELL AS THE TAIL BOOM, WERE UNDAMAGED. THE ENGINE AND FUEL SYSTEM HAD BEEN SECURED.
