Accident Details
A helicopter was substantially damaged during an in-flight collision with a lake while conducting an aerial application pass. The local flight was operating from a temporary load site near the lake shoreline.
Pilot Statement
The pilot reported that conditions at the time included calm winds and sunrise with the sun coming up over trees to the east, creating a glassy water condition. During the spray run, the pilot stated that he must have lost depth perception with the water surface, allowing the helicopter's skids to contact the water. The aircraft decelerated rapidly, and water came up over the bubble as the aircraft pitched forward. The pilot also noted that he should have looked at the trees along the shoreline for a vertical reference instead of at the water, because with glassy water it is hard to judge distance.
Aircraft and Operations
The pilot reported no malfunctions with the aircraft or engine prior to the accident. The helicopter was operating as an aerial application flight from a temporary load site near the lake.
