On July 9, 2004, at 1110 coordinated universal time (UTC), a Robinson R44 helicopter, Irish registration EI-DCO, impacted trees while flying near Derrybrien, Ireland. The pilot and one passenger were fatally injured, and one passenger sustained serious injuries. The helicopter was destroyed. The pilot operated the helicopter under the provisions of the Irish civil aviation regulations as a personal flight. The flight departed the Waterford Airport (EIWF) and was destined for Galway Airport (EICM).

En route, it entered an area of rising terrain and low cloud base, near Derrybrien, Co Galway. Radar tracking indicates that the helicopter slowed down, and then made a sharp turn before disappearing off the screen. The helicopter then suffered an in-flight collision with terrain directly after the loss of radar contact. A passenger died at the scene and the pilot died later in hospital. Another passenger survived with serious injuries. The probable cause was the pilot’s loss of spatial orientation resulting from inadequate visual reference with the ground due to limited visibility

CAUSE: Pilotīs spatial disorientation in low visibility after losing sight of the ground.
