The helicopter lifted off from a helipad at the 34th Street Heliport, New York City, New York, and made a left pedal turn. However, as it reached the end of the heliport platform and was flying slowly over the water, it settled in a nose low attitude. The pilot could not stop the descent and the helicopter went into the river. The pilot later reported that he had checked the wind and thought that it was from the southwest, giving a cross wind at take-off when, it fact, he took off with a tail wind.
The NTSB determined the probable cause to be: The pilot's misjudgement of the wind resulting in a downwind take-off. In addition, the loss of lift when the helicopter flew off the heliport platform, prior to reaching effective translational lift, resulted in the helicopter settling into the water.
