THE PILOT WAS TAKING THREE PASSENGERS FOR A LOCAL PLEASURE FLIGHT AND WHEN HE WAS ON APPROACH FOR THE AIRPORT, HE WAS INITIALLY NOT ABLE TO GET A DOWN AND LOCKED INDICATION FOR THE LANDING GEAR. HE WAS ABLE TO GET THE DOWN AND LOCKED INDICATION, BUT HIS SPEED GRADUALLY SLOWED DOWN TO 100 OR LESS AND HE SAID HE WAS 'HAVING SOME STALLING PROBLEMS.' HE SAID THE ENGINE SUDDENLY LOST POWER, BEGAN TO VIBRATE AND QUICKLY QUIT. DURING THE OFF AIRPORT FORCED LANDING, THE LEFT WING HIT A SMALL TREE, THEN THE RIGHT WING HIT A TREE AND THE AIRPLANE SWERVED TO THE RIGHT. THE MAIN GEAR COLLAPSED AND THE NOSE GEAR BENT TO THE SIDE.
