Narrative:

This is a report of an emergency landing that occurred. Upon closing on our target altitude, I attempted to add power to level off and discovered that there was a problem. I pushed the throttle in and no response. I immediately guessed that the carburetor had iced or there was a fuel problem or linkage problem. The carburetor heat was on at the beginning of the descent, so I changed the mixture, tried the throttle and no change from about 1400 RPM. At that point, I set best glide, called a helicopter to advise the FBO and set up for the landing. It appeared that there was little traffic on seawall and none at the road close to east beach condos but that would have been a stretch. I set up on the downwind and decided to go in downwind as there was only 1 vehicle on the road and we would set down about 200 yards in front of him. Seatbelts tight, fuel off, mixture out, magnetos off and 10 degrees flaps at 500 ft. Flaps 30 degrees shortly after over the vehicle and full after the wires and touchdown. Rolled to the side of the road and pushed the aircraft off the road. The conditions were perfect. Afterwards, I opened the inspection door on the cowl and the throttle cable was no longer attached and had only 1 nut on the end. FBO was contacted and after 30 mins the fire and police department arrived and I gave the fire department my particulars. The head pilot and the mechanic at FBO arrived and the cable was pointed out to the mechanic. I left the scene to return to work.

Narrative: THIS IS A RPT OF AN EMER LNDG THAT OCCURRED. UPON CLOSING ON OUR TARGET ALT, I ATTEMPTED TO ADD PWR TO LEVEL OFF AND DISCOVERED THAT THERE WAS A PROB. I PUSHED THE THROTTLE IN AND NO RESPONSE. I IMMEDIATELY GUESSED THAT THE CARB HAD ICED OR THERE WAS A FUEL PROB OR LINKAGE PROB. THE CARB HEAT WAS ON AT THE BEGINNING OF THE DSCNT, SO I CHANGED THE MIXTURE, TRIED THE THROTTLE AND NO CHANGE FROM ABOUT 1400 RPM. AT THAT POINT, I SET BEST GLIDE, CALLED A HELI TO ADVISE THE FBO AND SET UP FOR THE LNDG. IT APPEARED THAT THERE WAS LITTLE TFC ON SEAWALL AND NONE AT THE ROAD CLOSE TO EAST BEACH CONDOS BUT THAT WOULD HAVE BEEN A STRETCH.

SEATBELTS TIGHT, FUEL OFF, MIXTURE OUT, MAGNETOS OFF AND 10 DEGS FLAPS AT 500 FT. FLAPS 30 DEGS SHORTLY AFTER OVER THE VEHICLE AND FULL AFTER THE WIRES AND TOUCHDOWN. ROLLED TO THE SIDE OF THE ROAD AND PUSHED THE ACFT OFF THE ROAD. THE CONDITIONS WERE PERFECT. AFTERWARDS, I OPENED THE INSPECTION DOOR ON THE COWL AND THE THROTTLE CABLE WAS NO LONGER ATTACHED AND HAD ONLY 1 NUT ON THE END. FBO WAS CONTACTED AND AFTER 30 MINS THE FIRE AND POLICE DEPT ARRIVED AND I GAVE THE FIRE DEPT MY PARTICULARS. THE HEAD PLT AND THE MECH AT FBO ARRIVED AND THE CABLE WAS POINTED OUT TO THE MECH.
