Riverfront Heliport Airport
Aircraft Accident/Incident Report

Philadelphia, Pennsylvania 19101
Sunday, July 9, 1995 11:48 EDT

NTSB Narrative Summary Released at Completion of Accident

The pilot manuevered the helicopter for takeoff to the east, over the Delaware River. As the helicopter entered effective translational lift, it began to sink, and rotor rpm decreased. The pilot increased the throttle, but the rotor rpm did not increase in time. The skids contacted the water, resulting in the helicopter going into the water, and sinking. The pilot stated, 'I do not believe that there was a mechanical problem . . . I failed to maintain safe operating (rotor) rpm on takeoff.' The pilot also stated, 'he didn't give enough throttle and didn't stay ahead of the (rotor) rpm.'

NTSB Probable Cause Narrative

the pilot's failure to maintain aircraft control resulting in a collision with the water.
