Probable cause
The pilot in command not following the procedures outlined in the pilot's operating handbook.
Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
The pilot noticed that at liftoff the airplane's nose was higher than normal. He looked at the flap indicator and noticed he had selected full flaps. He attempted to retract some of the flaps and accidently selected full up. The airplane hit the tundra and came to a stop. According to the Cessna 172 pilot's operating handbook, the use of ten degrees of flaps is reserved for takeoffs from soft or rough fields. It further states that the flaps should not be retracted during the initial climb.
