On July 24, 1992, a Cessna 172RG (registration N4963R) operated by Emery Aviation College was involved in an aviation accident near Fairplay, CO. Investigators recorded the probable cause as: THE FLIGHT INSTRUCTOR'S OPERATION AT AN ALTITUDE INSUFFICIENT TO CLEAR OBSTACLES IN RISING MOUNTAINOUS TERRAIN. FACTORS WERE: HIGH DENSITY ALTITUDE, DIVERSION OF THE INSTRUCTOR'S ATTENTION, AND THE RISING TERRAIN. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive; 2 related events involving the same aircraft type or operator are linked below.
During a mountain flying checkout, an instructor took control to show a campsite, flying low through a valley below ridges. Video tape corroborated accounts; computed density altitude was 12,245 feet MSL.

Events
During the flight, the instructor took control of the airplane and indicated to both pilots that he wanted to show them a campsite where he had camped several weeks earlier. The instructor flew up a mountainous valley while the pilot operated a video camera. The passenger stated that they were flying at low altitude and below ridges rising on both sides of the airplane.
