Aircraft involved

Probable cause & findings

An in-flight collision with a flock of birds.

Factual narrative

During a dark night flight in visual meteorological conditions, an emergency medical services helicopter collided with a flock of birds about 1,100 ft above ground level. The impact shattered the windscreen and caused what the pilot described as an explosion. Despite the damage, the pilot was able to stabilize the helicopter and head towards the nearest airport, about 7.5 miles away. The helicopter landed without further incident. A post-accident examination revealed substantial damage to the main rotor blades in the pitch control cuff area and the monocoque structure of the fantail.
