NTSB summary
HISTORY OF FLIGHTOn October 15, 2015, about 1707 mountain daylight time, an Aviat Aircraft Incorporated, Husky A-1C-200, N280TB, sustained substantial damage when it impacted mountainous terrain about 13 miles east of Swan Valley, Idaho. The airline transport pilot was fatally injured and the passenger sustained serious injuries. The airplane was registered to and operated by the pilot under the provisions of 14 Code of Federal Regulations Part 91. Visual meteorological conditions prevailed, and no flight plan was filed for the local personal flight, which departed Alpine Airport (46U) Alpine, Wyoming, about 1646. During the flight, the accident airplane flew in loose formation with another airplane of the same type. According to the pilot of the second airplane, the pilots had planned to fly over a reservoir and dam, then climb to a higher elevation, to view a few remote lakes; however, the actual routing of the flight was not discussed. The pilot of the second airplane stated that after completing the flight around the reservoir, both airplanes climbed, with the accident airplane in the lead position. As they approached a ridgeline, he radioed the accident pilot and stated that he was going to perform a 360° climbing turn to gain altitude before crossing the ridgeline, and the accident pilot acknowledged. As he completed the turn, he noted a dust cloud near the ground and realized that the lead airplane had impacted terrain. He circled the area, to assist in notifying authorities of the accident and to assist with the recovery effort. The accident airplane was equipped wi
Probable cause
The pilot's failure to maintain airspeed while maneuvering in high density altitude conditions over mountainous terrain, which resulted in the airplane exceeding its critical angle of attack and experiencing an aerodynamic stall.
