SEA07LA147

After landing and observing the crewmember unbuckle his seat belt, disconnect his headset communication cord and exit the helicopter, the pilot initiated a vertical takeoff; the pilot did not observe the crewmember as he ascended. About 10 to 15 feet above the ground the pilot sensed something similar to a load being released from the helicopter, and after repositioning the helicopter he observed the crewmember in an apple tree. The crewmember's headset's radio cord had become inadvertently entangled with the structure of the helicopter, separating after the aircraft initiated its ascent, resulting in the crewmember falling into the apple tree. It could not be determined where the helmets cord became entangled with the helicopter.

On June 6, 2007, approximately 0550 Pacific daylight time, a Hughes 369D, N48MP, was involved in an accident near Troy, Utah, which resulted when a suspended passenger fell from the helicopter during the helicopter's ascent. The aircraft was registered to a private individual and operated by the certificated commercial pilot. The pilot and one passenger were not injured, while a second passenger received serious injuries. The helicopter was not damaged. Visual meteorological conditions prevailed for the flight, which was engaged in netting and collaring of elk calves by the Oregon Fish and Wildlife Service as a 14 CFR Part 91 operation. A company flight plan was on file. The local flight departed a staging area located 1 nautical mile from the accident site about 5 minutes prior to the accident.

In a telephone conversation with the NTSB investigator-in-charge (IIC), and according to the Pilot/Operator Aircraft Accident/Incident Report (NTSB Form 6120.1), the pilot reported that after arriving at his destination on the first flight of the day "I lowered the helicopter and let the crewmember out of the aircraft. I watched him unbuckle his seat belt, unplug [his headset] and exit. When he was 'feet-on-the ground', I pulled slowly, vertically up; we could not see him." The pilot reported that after ascending to an altitude of between 10 to 15 feet above the ground he [still] could not see the crewmember, "...[and] at this time I lowered the aircraft in case he had jumped back on, when I felt a 'release'. I was already descending and continued to land with a 180-degree turn to the west." The pilot stated that as he was landing he could see the crewmember [lodged] in an apple tree. The pilot further revealed that after landing and while treating the crewmember, he noticed the plug at the end of the helmet's cord was pulled off.

A Federal Aviation Administration inspector reported to the IIC that the crewmember's helmet's communication cord had inadvertently become entangled with a part of the helicopter's structure, eventually separating as the helicopter ascended, resulting in the crewmember falling into the apple tree. The inspector further reported that he could not identify the specific area of the helicopter where the cord became entangled, as there was no evidence of damage to the helicopter.
