Agusta A109A II, Edmonds, Wash., Sept. 29, 2005–The NTSB could not determine the reason for loss of control during the maneuvering flight, which resulted in “an in-flight collision with water.” The helicopter was returning to base at night, over the ocean. It followed the coastline at 800 feet msl, then turned away from the shore at about 9:13 p.m. 
Witnesses reported low clouds and restricted visibility in rain, mist and fog. The aviation weather reporting station five miles from the accident site reported wind from the southwest at 6 knots, visibility restricted in light rain and mist, and a ceiling ranging from 200 to 800 feet. Conditions deteriorated within 30 minutes of the accident, with visibility lowering to a quarter mile in dense fog and ceilings at 200 feet.
The ATP-certified pilot was instrument rated and current, and the helicopter was equipped and certified for IFR flight. The pilot and two flight nurses were killed. The helicopter was operated by CJ Systems Aviation Group of West Mifflin, Pa.
