THE PILOT OF THE MODIFIED PIPER PA-22 WAITED AT THE AIRSTRIP UNTIL THE TEMPERATURE COOLED AS MUCH AS POSSIBLE BEFORE DUSK. HE STATED THAT HE USED FULL FLAPS FOR CLIMBOUT, A TECHNIQUE WHICH HE BELIEVED TO BE RECOMMENDED BY THE OWNER'S HANDBOOK. THE AIRCRAFT CRASHED APPROXIMATELY 1/2 MILE FROM THE DEPARTURE END OF THE AIRSTRIP. CAUSE: THE PILOT'S MISJUDGEMENT IN PREFLIGHT PLANNING WHEN DEPARTING TOWARD RISING TERRAIN. CONTRIBUTING FACTORS IN THIS ACCIDENT WERE HIS DECISION TO ATTEMPT A CLIMB-OUT WITH FULL FLAPS EXTENDED, AND THE MINIMAL PERFORMANCE DATA AVAILABLE TO HIM UPON WHICH HE COULD BASE HIS DECISION.
