NTSB narrative
THE PILOT AND PASSENGER WERE DEPARTING FROM A LOT THAT WAS SURROUNDED BY OBSTRUCTIONS. ACCORDING TO THE PILOT, HE TOOK OFF IN A HOVER, THEN AS THE HELICOPTER WAS PASSING TREES AT ABOUT 70 FEET AND 30 TO 35 KNOTS, IT BEGAN SPINNING TO THE RIGHT. HE SAID HE TRIED TO STOP THE TURNING WITH LEFT PEDAL, WHICH DID NOT CORRECT THE PROBLEM. HE ENTERED AN AUTOROTATION TO A ROAD. DURING THE AUTOROTATIVE LANDING, THE HELICOPTER TOUCHED DOWN HARD, DAMAGING THE UNDERSIDE OF THE AIRFRAME. ACCORDING TO WITNESSES, THE MAIN ROTOR BLADES CLIPPED A TREE, BUT NO BLADE DAMAGE WAS REPORTED. POST-ACCIDENT EXAMINATION REVEALED NO PREIMPACT MECHANICAL DISCREPANCIES. ACCORDING TO THE HEIGHT-VELOCITY DIAGRAM IN THE R22 OPERATING HANDBOOK, DIRECTIONAL CONTROL WAS LOST WHEN THE HELICOPTER WAS OUTSIDE THE AREA FOR THE 'RECOMMENDED TAKE-OFF PROFILE' (AIRSPEED/ALTITUDE ENVELOPE FOR A SUCCESSFUL AUTOROTATION).
Probable cause
THE PILOT'S FAILURE TO MAINTAIN DIRECTIONAL CONTROL. A FACTOR RELATED TO THE ACCIDENT WAS: THE HELICOPTER WAS OUTSIDE THE HEIGHT-VELOCITY ENVELOPE (FOR A SUCCESSFUL AUTOROTATION), WHEN LOSS OF DIRECTIONAL CONTROL OCCURRED.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
