NTSB summary
HISTORY OF FLIGHT On September 5, 2011, at 1514 central daylight time, a Hoffman HK36R Super Dimona motorglider impacted terrain while maneuvering near Winsted Municipal Airport (10D), Winsted, Minnesota. The commercial pilot sustained fatal injuries and the pilot-rated passenger sustained serious injuries. The motorglider was registered to Koair Corporation, Eden Prairie, Minnesota, and operated by the pilot. Visual meteorological conditions prevailed, and a flight plan was not filed for the 14 Code of Federal Regulations Part 91 personal flight. The flight originated from Flying Cloud Airport (FCM), Minneapolis, Minnesota, at an unknown time. According to a telephone interview with the passenger, which was conducted by a Federal Aviation Administration (FAA) inspector, the purpose of the flight was familiarization for the passenger who was scheduled to conduct an instructional flight in the accident motorglider the following day. Unable to find adequate thermals during the flight, the pilot asked the passenger if he wanted to observe a landing prior to returning to FCM. They overflew 10D to verify the wind conditions, which were estimated to be less than 5 knots and appeared to favor runway 9, and entered a left downwind for runway 9. The pilot announced his intentions over the radio. A Cessna Caravan on the ground at 10D announced his intention to hold short of the runway, but was then observed by the pilot and passenger to back taxi on the runway. Approximately 1,000 feet above ground level, the passenger felt they had adequate altitude to continue the approach and glid
Probable cause
The pilot did not maintain adequate airspeed while maneuvering at low altitude, which resulted in an aerodynamic stall.
