## Probable cause

The pilot's inadequate preflight/pretakeoff procedure by not lowering the wing flaps, which resulted in an inadvertent stall as the pilot attempted to climb out of ground effect to clear a corn crop at the end of the runway.  A factor in the accident was the failure, for undetermined reasons, of the flaps to deploy during the takeoff roll when the pilot moved the switch.
