Investigating agency: AAIB
Narrative:
The pilot lost control of the helicopter whilst manoeuvring at low speed to approach a hilltop landing site in quite strong wind conditions. It descended rapidly with increasing forward ground speed, before striking the ground short of the point of intended landing and passing through a substantial stone wall. The helicopter was destroyed but the occupants suffered only minor injuries. The investigation determined that an error of judgement or perception led the pilot to attempt a downwind approach. A combination of human factors was thought to have contributed to the accident

The helicopter was engaged on a task for the Police Service of Northern Ireland (PSNI), ferrying personnel and equipment to and from the site of a helicopter accident which had occurred 5 days earlier, on 23 October 2010. The site was in the Mourne Mountains, near to the top of the 626 m (2,054 ft) amsl Shanlieve hill. A PSNI control point, from where passengers embarked for the ferry flights, had been established in a valley about 3 km from the site.
