Probable cause
Inadvertent closing of the mixture by the pilot. Factors related to the accident are inadequate control shape, or size, and inattentiveness of the pilot.
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 was climbing out after takeoff for an agricultural operation. At 250 feet AGL he reduced power and RPM, and started a turn. The pilot then realized that the RPM was dropping and he had no power. A hard landing which resulted in a nose over was made in a farmer's field. The propeller control and the mixture are in close proximity to each other, and are the same shape and size in this model aircraft.
