On November 3, 1997, about 1250 eastern standard time, a Cessna 172, N4105F, registered to Candy Can Do Inc., leased by Crystal Aero Group Inc, operating as a 14 CFR Part 91 instructional flight, crashed on landing at Crystal River Airport, Crystal River, Florida. Visual meteorological conditions prevailed and no flight plan was filed. The airplane sustained substantial damage. The certified flight instructor and private pilot receiving instruction reported no injuries. The flight originated from Inverness, Florida, about 1 hour 20 minutes before the accident. The CFI stated the student rated private pilot was flying the airplane and entered the traffic pattern for a left downwind to runway 27. He encountered a crosswind from the right on short final and started his landing flare at about 20 feet. A strong gust of wind caught the right wing, lifting it, and the left wing collided with the runway. The airplane veered to the left, departed the runway and collided with an embankment. Review of weather information obtained from Gainesville Automated Flight Service Station, for the period of the accident revealed no recorded record of turbulence, downdrafts, gusts, or windshear.
