THE HELICOPTER COLLIDED WITH A SMALL TREE ABOUT 8 FT HIGH DURING A FORCED LANDING AT NIGHT AFTER A POWER LOSS. THE COLLISION BROKE THE TAIL BOOM AND A HARD LANDING CAUSED THE FAILURE OF A LANDING SKID AND DAMAGED THE MAIN ROTOR. THE PLT HAD TAKEN TWO FRIENDS FOR A NIGHT FLT AND AFTER A SHORT FLIGHT THE ENGINE QUIT. THE FORCED LANDING FOLLOWED. DURING THE POST ACCIDENT INVESTIGATION THE FUEL IN THE ACFT WAS FOUND TO BE DIRTY. BECAUSE OF A FUEL BYPASS THAT PERMITSCONTINOUS FUEL FLOW TO THE ENGINE BYPASSING THE MAIN FUEL FILTER FUEL CONTAMINATION WAS NOT CONSIDERED TO BE A CRITICAL FACTOR IN THIS INSTANCE.
