Aircraft Accident/Incident Report
Hudson, Colorado 80621
Sunday, June 19, 2005 12:55 MDT
NTSB Narrative Summary Released at Completion of Accident
The flight instructor and his private pilot student were practicing touch and go landings. The student did not turn the carburetor heat off or put up the flaps after his touch and go, so the instuctor took control of the airplane. He turned off the carburetor heat and he said he got "hasty" and retracted the flaps completely instead of in gradual increments. The aircraft experienced a loss of lift and touched down on soft ground and nosed over. The temperature at the time of the accident was 92 degrees Fahrenheit with a calculated density altitude of 7713 feet msl.
NTSB Probable Cause Narrative
The flight instructor's improper use raising of the flaps. Contributing factors were the student pilot's misunderstanding of the instructor's intentions, the instructor's inadequate supervision of the student pilot, the density altitude, and the soft terrain.
