Narrative:
The helicopter was engaged in aerial filming of the Megalithic Passage Tomb at Newgrange, Co. Meath. During its fourth orbit of the mound, the helicopter was seen to yaw suddenly to the right and spiral out of control. Appropriate corrective action by the Pilot i.e., of opposite left pedal, reduction of collective and pitching the nose down to increase airspeed, proved ineffective as the helicopter continued yawing right in a spiral descent. The helicopter impacted heavily into a field immediately east of the mound, but remained upright. The three persons on board suffered various sudden impact injuries and were transferred to hospital by the emergency services a short time later. There was no fire. Pilot seriously injured, passengers minor injuries.

Operation of the helicopter in a flight regime and relative wind velocities / azimuths which were conducive to the loss of Tail Rotor Effectiveness (LTE).

Contributory Factors
1. A lack of awareness by the Pilot on the phenonmenon of LTE.
2. Available safety related material pertaining to the phenonmenon of the LTE was not disseminated correctly to the appropriate pilots.
3. The non-inclusion of safety related material pertaining to LTE in appropriate helicopter Flight Manuals.
