## Analysis

The pilot reported that, while on final approach to runway 31, the airplane flew through windy conditions and a "severe down wind shear." He said that the wind "drove" the airplane into the runway, and the airplane bounced a couple times. The left main landing gear contacted the snow and the airplane exited the runway, which resulted in substantial damage to the lower fuselage. The pilot indicated that there were no mechanical malfunctions or failures with the airplane. About 20 minutes before the accident, the recorded wind at the airport was 260° at 11 kts, gusting to 19 kts.

## Factual narrative

On December 20, 2016, about 0936 central standard time, a Cessna 210N airplane, N80RB, sustained substantial damage in an accident at Longville Municipal Airport (XVG), Longville, Minnesota. The private pilot was not injured. The airplane was privately registered and operated under the provisions of Title 14 Code of Federal Regulations Part 91 as a personal flight. Day visual meteorological conditions prevailed for the flight, and the flight was not operated on a flight plan. The flight originated from the Winsted Municipal Airport, near Winsted, Minnesota, about 0800, and was en route to XVG.The pilot indicated that the Automated Weather Observing System (AWOS) was one of the sources of weather he used for the flight. At 0916, the recorded wind at XVG was 260° at 11 kts gusting to 19 kts. He reported, that while on final approach to runway 31, the airplane flew through windy conditions and a "severe down wind shear." He said that the wind "drove" the airplane into the runway and the airplane bounced a couple times. The left main landing gear contacted snow and pulled the airplane off the runway. The pilot indicated that there were no mechanical issues with the airplane. A witness plowing snow at XVG stated that the airplane touched down about halfway down the runway. The nose landing gear hit the ground first, the airplane bounced up about 50 to 75 ft, veered sideways when it came down, and then exited the west side of the runway. A Federal Aviation Administration (FAA) Inspector examined the airport and airplane. He confirmed that there were initial witness marks consistent with propeller strikes on the runway about 1,430 ft from the approach end of the runway. Ground scars and displaced snow were present in the snow windrow in the runway infield near the wreckage. The lower fuselage near the main cabin area exhibited substantial structural damage.
