(-23) AFTER TAKEOFF FROM SAN YNEZ AIRPORT, WHILE CLIMBING, THE AFT CYLINDER, AFT SPARK PLUG, DEPARTED THE AIRCRAFT.  THIS CAUSED THE ENGINE TO LOSE POWER AND THE FAILURE OF THE FRONT CYLINDER.  THE AIRCRAFT LANDED IN A FARM FIELD DIRT ACCESS ROAD.  THE AIRCRAFT EXPERIENCED A HARD LANDING CAUSING THE RIGHT MAIN LANDING GEAR TO COLLAPSE.
