## Analysis

THE ACFT LANDING GEAR COLLAPSED DURING A FORCED LANDING ON A ROUGH ROAD. THE ACFT ENGINE HAD QUIT WHILE CLIMBING THROUGH4500 FT AFTER TAKEOFF. THE PILOT TRIED LEANING AND PITOT HEAT. SINCE THE ENGINE WOULD NOT START THE PILOT PICKED A DIRT ROAD FOR LANDING. THE ENGINE RESTARTED JUST BEFORE TOUCHDOWN BUT THE PILOT COULD NOT CLIMB WITH FULL FLAPS SO WHEN THE GEAR TOUCHED HE CONTINUED THE LANDING. THE GEAR BROKE OFF DURING THE ROLL-OUT.
