time doesn’t seem to have been the issue
The front left seat passenger stated that the pilot told him that “he was not going to make it.” The passenger asked the pilot if there was a problem with the helicopter, and the pilot told him that it is not the helicopter, “it is me.” The front seat passenger saw the pilot slump over and was not responsive. The passenger reached over to the flight controls, retarded the throttle, and attempted to control the helicopter until water impact. The passenger estimated that he started to control the helicopter about 400 ft above the water. At some point during the descent, the passenger activated the skid-mounted float system.
