NTSB Narrative Summary Released at Completion of Accident

On May 6, 2014, about 1200 mountain daylight time, a Mooney M20C, N6704U, collided with mountainous terrain near Cody, Wyoming. The airplane was registered to, and operated by, the owner under the provisions of 14 Code of Federal Regulations Part 91. The private pilot/owner and private pilot rated passenger were presumed to have sustained fatal injuries. The airplane sustained substantial damage to the forward fuselage and both wings. The cross-country personal flight departed Yellowstone Regional Airport, Cody, about 1140, with a presumed destination of Twin Falls, Idaho. Instrument meteorological conditions prevailed at the accident site, and no flight plan had been filed. Both occupants were brothers, and had departed from Fayetteville, North Carolina, on April 28, in the accident airplane, with the intention of touring the country to visit friends and relatives. Their ultimate destination was the Seattle area, where they had planned on arriving by May 11. Family members became concerned when they had not heard from both occupants by May 8, and initiated a series of exchanges with various local law enforcement agencies and airport managers throughout the Cody and Twin Falls area. On May 10, still unable to locate the occupants, family members contacted Lockheed Martin Flight Services, and an Alert Notice (ALNOT) was issued. Utilizing radar data provided by the Air Force Rescue Coordination Center, search and rescue personnel from the Park County Office of Homeland Security were able to visually locate the airplane by helicopter in the Shoshone National Forest. As of the publication of this report, due to the inhospitable nature of the terrain, the accident site was inaccessible to both NTSB and search and rescue personnel.
