AFTER PRE-HEATING THE AIRPLANE, AND AFTER A PRE-FLIGHT INSPECTION WHICH REVEALED NO DISCREPANCIES OR CONTAMINATED FUEL, THE PILOT TOOK OFF AND CLIMBED TO 2,220 FEET MSL. ABOUT 30 SECONDS AFTER SELECTING CRUISE POWER, THE ENGINE LOST PARTIAL POWER. THE ENGINE WAS 'BARELY KEPT ALIVE' BY USE OF THE AUXILIARY FUEL PUMP, BUT FULL POWER COULD NOT BE REGAINED DESPITE THE COMPLETION OF THE EMERGENCY CHECKLIST. A FORCED LANDING WAS MADE IN A WOODED AREA, AND THE AIRPLANE STRUCK TREES.
