Analysis 

The Safety Board's full report is available at http://www.ntsb.gov/investigations/AccidentReports/Pages/aviation.aspx. The Aircraft Accident Report number is NTSB/AAR-19/04.

On March 11, 2018, about 1908 eastern daylight time, an Airbus Helicopters AS350 B2, N350LH, lost engine power during cruise flight, and the pilot performed an autorotative descent and ditching on the East River in New York, New York. The pilot sustained minor injuries, the five passengers drowned, and the helicopter was substantially damaged. The FlyNYON-branded flight was operated by Liberty Helicopters Inc. (Liberty), per a contractual agreement with NYONair; both companies considered the flight to be an aerial photography flight operated under the provisions of Title 14 Code of Federal Regulations (CFR) Part 91. (During this accident investigation, the Federal Aviation Administration determined that Liberty operated the flight as a nonstop commercial air tour under 14 CFR Part 91.) Visual flight rules weather conditions prevailed, and no flight plan was filed for the intended 30-minute local flight, which departed from Helo Kearny Heliport, Kearny, New Jersey, about 1850. 

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
Liberty Helicopters Inc.'s use of a NYONair-provided passenger harness/tether system, which caught on and activated the floor-mounted engine fuel shutoff lever and resulted in the in-flight loss of engine power and the subsequent ditching. Contributing to this accident were (1) Liberty's and NYONair's deficient safety management, which did not adequately mitigate foreseeable risks associated with the harness/tether system interfering with the floor-mounted controls and hindering passenger egress; (2) Liberty allowing NYONair to influence the operational control of Liberty's FlyNYON flights; and (3) the Federal Aviation Administration's inadequate oversight of Title 14 Code of Federal Regulations Part 91 revenue passenger-carrying operations. Contributing to the severity of the accident were (1) the rapid capsizing of the helicopter due to partial inflation of the emergency flotation system and (2) Liberty and NYONair's use of the harness/tether system that hindered passenger egress.
