14 CFR Part 91: General Aviation
Accident occurred Sunday, August 14, 2011 in Burley, ID

Aircraft: CESSNA P210N, registration: N7825K
Injuries: 4 Fatal.
NTSB investigators either traveled in support of this investigation or conducted a significant amount of investigative work without any travel, and used data obtained from various sources to prepare this aircraft accident report.
Witnesses reported that during the takeoff, the airplane lifted off about three-quarters of the way down the runway. The landing gear was retracted and almost immediately, about 75 feet above ground level, the airplane entered a left turn and began to descend. The left descending turn continued to ground impact. On the day of the accident, the airplane was operating in high density altitude conditions, and was taking off with a tailwind of about 6 to 10 knots. The airplane was loaded at, or very near to, its maximum allowable takeoff weight. (The takeoff weight was estimated to be within 50 pounds, plus or minus, of its maximum takeoff gross weight of 4,000 pounds.) The combination of the high density altitude, the tailwind, and the high gross weight most likely resulted in the pilot not being able to maintain altitude once the vertical component of the lift vector was reduced as a result of the bank angle during the left turns, which ultimately lead to the descent into the terrain. Postaccident examination of the airframe and engine revealed no evidence of a mechanical malfunction or failure that would have precluded normal operation.
The National Transportation Safety Board determines the probable cause(s) of this accident to be: The pilot's failure to attain sufficient altitude and maintain aircraft control during a turn shortly after liftoff while operating at maximum gross weight, with a tailwind, and in high density altitude conditions.
