Narrative:

I was hired to conduct a flight review. After clearing turns, we were going to execute a power-off stall. When the pilot retarded the throttle, the throttle cable broke. The spring-loaded throttle advanced to a full power setting. We were at 3000 ft over the ocean approximately 5 mi southwest of toa airport. After positive control of the aircraft was attained, we radioed toa tower and advised them of our situation and that we intended to return for landing. We were immediately cleared to land. We could not land at this point because we could not lose altitude fast enough at the high power setting. We began orbiting the airport at 2000 ft AGL. We reduced the mixture setting to decrease power and airspeed. After about 5 orbits, we landed uneventfully with crash crews waiting. No injuries or aircraft damage resulted. The cable broke just inside the panel. The aircraft is a C182N, 1980 model yr. The reason for the break is unknown.

Title: INSTRUCTOR PLT IN A C182 GIVING A FLT REVIEW HAS A THROTTLE CABLE BREAK AND SPRING INTO FULL PWR SETTING. AFTER CIRCLING TO LOSE ALT, A SAFE LNDG WAS MADE.

Narrative: I WAS HIRED TO CONDUCT A FLT REVIEW. AFTER CLRING TURNS, WE WERE GOING TO EXECUTE A PWR-OFF STALL. WHEN THE PLT RETARDED THE THROTTLE, THE THROTTLE CABLE BROKE. THE SPRING-LOADED THROTTLE ADVANCED TO A FULL PWR SETTING. WE WERE AT 3000 FT OVER THE OCEAN APPROX 5 MI SW OF TOA ARPT. AFTER POSITIVE CTL OF THE ACFT WAS ATTAINED, WE RADIOED TOA TWR AND ADVISED THEM OF OUR SIT AND THAT WE INTENDED TO RETURN FOR LNDG. WE WERE IMMEDIATELY CLRED TO LAND. WE COULD NOT LAND AT THIS POINT BECAUSE WE COULD NOT LOSE ALT FAST ENOUGH AT THE HIGH PWR SETTING. WE BEGAN ORBITING THE ARPT AT 2000 FT AGL. WE REDUCED THE MIXTURE SETTING TO DECREASE PWR AND AIRSPD. AFTER ABOUT 5 ORBITS, WE LANDED UNEVENTFULLY WITH CRASH CREWS WAITING. NO INJURIES OR ACFT DAMAGE RESULTED. THE CABLE BROKE JUST INSIDE THE PANEL. THE ACFT IS A C182N, 1980 MODEL YR. THE REASON FOR THE BREAK IS UNKNOWN.
