From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

(-23) On base final to the west 30th street heliport (jra) over the Hudson River in NY, during a sight-seeing tour with seven passengers onboard, pilot experienced a loud bang noise, followed by airframe vibration. PIC elected to perform a forced landing by deploying the skid's floats and autorotated onto the River north of the lincoln tunnel, adjacent to wechawkin, NJ. Nearby boaters rescued the passengers and the PIC. The rotorcraft was towed to port liberte, jersey city, NJ.
