DURING TAKEOFF ROLL THE PILOT NOTED THAT THE AIRPLANE WAS NOT GENERATING ENOUGH AIRSPEED TO FLY. PRIOR TO REACHING THE END OF THE RUNWAY, THE PILOT 'PULLED THE NOSEWHEEL OF THE AIRPLANE OFF THE GROUND AND BOUNCED INTO THE AIR.' HE LEVELED THE NOSE WHEN THE AIRPLANE WAS APPROXIMATELY 10-15 FEET ABOVE THE GROUND BUT THE AIRPLANE IMMEDIATELY ROLLED LEFT AND THE LEFT WING STRUCK THE GROUND. THE AIRFIELD WAS DESCRIBED AS A GRASS STRIP WITH A SIGNIFICANT UPSLOPE. THE GRASS WAS APPROXIMATELY A FOOT HIGH AND WET. NO GUIDANCE IS PROVIDED IN THE PILOT'S OPERATING HANDBOOK FOR TAKEOFF ON WET OR UNPREPARED SURFACES. THE PA-28-236 TAKEOFF GROUND ROLL CHART FOR A DRY, PAVED RUNWAY, USING THE CONDITIONS EXISTING AT THE TIME OF THE ACCIDENT, INDICATES A TAKEOFF GROUND ROLL OF 1000 FEET.
The National Transportation Safety Board determines the probable cause(s) of this accident to be: the pilot's failure to abort the takeoff and the premature liftoff which resulted in an inadvertent stall. Factors relating to this accident are improper planning and decision by the pilot, and the tall, wet grass. Full narrative available
