NTSB summary
On August 22, 2010, about 0833 Pacific daylight time, a Cessna 172E airplane, N7807U, sustained substantial damage following an in-flight collision with terrain at the Mammoth Yosemite Airport, Mammoth Lakes, California. The private pilot and three adult passengers sustained serious injuries. The airplane sustained structural damage to the forward fuselage and wings. The airplane was being operated by the pilot as a personal cross-country flight under the provisions of 14 Code of Federal Regulations (CFR) Part 91, when the accident occurred. Visual meteorological conditions prevailed, and no flight plan was filed. The flight originated from Mammoth Lakes. In a written statement to the National Transportation Safety Board (NTSB), the pilot reported that shortly after takeoff the airplane encountered turbulence and a downdraft, and began to lose altitude rapidly. The pilot stated he tried to control the airplane; however, it impacted terrain in a nose-low attitude. During a telephone conversation with the NTSB investigator-in-charge, the front seat passenger stated that the takeoff roll was long and they "had a little time taking off, gradually going up with the buzzer going off." He reported that shortly after liftoff, the airplane encountered an updraft followed by a downdraft. He stated the pilot initiated a turn to the left which was followed by a "stall." The four-seat, high-wing, fixed-gear airplane was manufactured in 1964, and powered by a Continental O-300, 145-hp engine. The airplane was equipped with a fixed-pitch propeller.

Probable cause
The pilot’s failure to maintain adequate airspeed and airplane control during takeoff in high density altitude conditions, which resulted in an aerodynamic stall.
