An excerpt from the NTSB preliminary report detailing a fatal foot selfie scenario:
...As the helicopter neared the eastern boundary of Central Park, the pilot slowed the helicopter to between 20 and 30 knots groundspeed so the passengers could take photographs. At this point, he noticed that the front passenger's restraint was hanging from the seat. He picked it up, tapped the passenger, and told him to put it back on, which he did. During the interview the pilot also recalled that other passengers had inadvertently released their seatbelts during previous flights.
As they were flying along the eastern side of Central Park, the front seat passenger turned sideways, slid across the double bench seat toward the pilot, leaned back, and extended his feet to take a photograph of his feet outside the helicopter. As the pilot initiated a right pedal turn to begin to head south, the nose of the helicopter began to turn right faster than he expected, and he heard a low rotor rpm alert in his headset. He then observed engine pressure and fuel pressure warning lights and believed he had experienced an engine failure. He lowered the collective pitch control to maintain rotor rpm and let the nose continue to turn to the right. Central Park came into view and he briefly considered landing there but thought there were "too many people." He continued the turn back toward the East River and made his first distress call to air traffic control. He yelled to the passengers to get back in their seats. Due to the helicopter's airspeed, he was not sure he could make it to the East River and reduced rotor rpm so he could "glide better." Once he was in an established autorotative glide, he attempted to restart the engine but was unsuccessful. He waited 1 or 2 seconds and tried the starter again, but there were no positive indications of a successful engine restart on the instrumentation. He checked the fuel control lever and found that it was still in its detent for normal operation. When he was sure he could clear the buildings and make it to the river, he activated the floats at an altitude of about 800 ft agl.
At this point he was "committed to impact," and, when he reached down for the emergency fuel shutoff lever, he realized that it was in the off position. He also noted that a portion of the front seat passenger's tether was underneath the lever.
As the helicopter continued to descend through 600 ft agl, he positioned the fuel shutoff lever to the "on" position and attempted to restart the engine. He observed positive indications on the engine instruments immediately. As the helicopter descended through 300 ft, he realized that the engine "wasn't spooling up fast enough," and, given the helicopter's proximity to the surface, he had to continue the autorotation. He again reached for the fuel shutoff lever and positioned it back to "off." Passing through between 100 and 50 ft, he began the cyclic flare in an extended glide configuration, but he "did not get a lot of rpm back." He performed a flare reduction at 10 to 15 ft. He pulled the collective pitch control up "as far as it would go." The helicopter then impacted the water at 5° to 10° nose-up attitude.
After impacting the water, the chin bubble on the pilot's side began to fill with water, which quickly covered the floor. He kept his restraint on and reached down for the front seat passenger's carabiner attachment to the helicopter. He turned the knurled screw "two or three rotations"; by that time, the helicopter was "listing past a 45° roll." He then decided to egress the helicopter, and by the time he unbuckled his restraint, he was fully under water. He used two hands to grab the door frame and pull himself out. He surfaced about 4 ft away from the nose of the helicopter and crawled up onto the belly. He stood up and waved for help but could not see anything.
