NTSB narrative
THE PLT STATED THAT DURING HIS FIRST PASS WHILE OVER TREES, FOR A PHOTOGRAPHIC RUN, THE HELICOPTER EXPERIENCED A SLIGHT YAWING TENDENCY. DURING THE SECOND PASS AT THE SAME AIRSPEED BUT AT A LOWER ALTITUDE (BETWEEN 25 AND 50 FT ABOVE THE TREES) THE HELICOPTER ENTERED AN UNCOMMANDED RT YAW. HE LOWERED THE COLLECTIVE CONTROL AND PUSHED THE CYCLIC BUT DID NOT ADJUST THE THROTTLE. THE SPINNING DESCENT CONTINUED UNTIL IMPACT WITH THE TREES THEN THE GROUND. EXAM OF THE DAMAGED TAIL ROTOR BLADES BY AN FAA AIRWORTHINESS INSPECTOR INDICATE EVIDENCE OF ROTATION AT IMPACT. THE PLT'S BOSS WAS THE PHOTOGRAPHER.
Probable cause
INCORRECT AIRSPEED, INSUFFICIENT AIRSPEED, AND FAILURE OF THE PILOT IN COMMAND TO PERFORM THE CORRECT EMERGENCY PROCEDURE FOLLOWING THE IN FLIGHT LOSS OF CONTROL. CONTRIBUTING TO THE ACCIDENT WAS SELF INDUCED PRESSURE BY THE PILOT IN COMMAND.

Source notes (4)
- 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.
