Narrative:

Night cargo flight cle-ind. Arriving ind from the northeast, landing runway in use at ind was runway 5R/left. Approximately 15 mi from the airport and still to the northeast, the runway was changed to land runway 23L/right. We were at 7000 ft MSL on a vector and only about 5 mi from larez (OM for runway 23L), when approach control cleared us for ILS runway 23L. Crossing altitude at larez OM is approximately 2700 ft MSL. Even with the aircraft in the landing confign, we crossed larez at around 3500 ft MSL. Both the captain and I agreed we were too high, we both agreed we didn't like our situation, and we both agreed to abandon the approach. The captain then activated the toga levers as I was calling the tower to state that we were going around. The tower stated 'roger,' and told us to maintain 3000 ft. We had already gotten to within 3-4 mi of the runway and down to 2700 ft MSL when the toga levers were activated. We had already passed through 3000 ft on the go around with toga power still applied. The autoplt and autothrottles were then disconnected, the airplane was immediately manually controled, but we were now at approximately 3500 ft and descending back to 3000 ft and visually directly over the runway. Tower restated to maintain 3000 ft, which we did, and we returned downwind for another approach and uneventful landing. 2 main causes resulted in this situation. 1) change in landing runway in close, leaving us 'high and hot.' 2) activation of toga close to the already selected missed altitude of 3000 ft with superior aircraft performance, prevented captured altitude leveloff.

Title: CAPT OF AN AIRBUS A310 OVERSHOT ASSIGNED ALT DURING GAR DUE TO GAR CLB PWR SET AND CLOSE PROX TO ASSIGNED ALT.

Narrative: NIGHT CARGO FLT CLE-IND. ARRIVING IND FROM THE NE, LNDG RWY IN USE AT IND WAS RWY 5R/L. APPROX 15 MI FROM THE ARPT AND STILL TO THE NE, THE RWY WAS CHANGED TO LAND RWY 23L/R. WE WERE AT 7000 FT MSL ON A VECTOR AND ONLY ABOUT 5 MI FROM LAREZ (OM FOR RWY 23L), WHEN APCH CTL CLRED US FOR ILS RWY 23L. XING ALT AT LAREZ OM IS APPROX 2700 FT MSL. EVEN WITH THE ACFT IN THE LNDG CONFIGN, WE CROSSED LAREZ AT AROUND 3500 FT MSL. BOTH THE CAPT AND I AGREED WE WERE TOO HIGH, WE BOTH AGREED WE DIDN'T LIKE OUR SIT, AND WE BOTH AGREED TO ABANDON THE APCH. THE CAPT THEN ACTIVATED THE TOGA LEVERS AS I WAS CALLING THE TWR TO STATE THAT WE WERE GOING AROUND. THE TWR STATED 'ROGER,' AND TOLD US TO MAINTAIN 3000 FT. WE HAD ALREADY GOTTEN TO WITHIN 3-4 MI OF THE RWY AND DOWN TO 2700 FT MSL WHEN THE TOGA LEVERS WERE ACTIVATED. WE HAD ALREADY PASSED THROUGH 3000 FT ON THE GAR WITH TOGA PWR STILL APPLIED. THE AUTOPLT AND AUTOTHROTTLES WERE THEN DISCONNECTED, THE AIRPLANE WAS IMMEDIATELY MANUALLY CTLED, BUT WE WERE NOW AT APPROX 3500 FT AND DSNDING BACK TO 3000 FT AND VISUALLY DIRECTLY OVER THE RWY. TWR RESTATED TO MAINTAIN 3000 FT, WHICH WE DID, AND WE RETURNED DOWNWIND FOR ANOTHER APCH AND UNEVENTFUL LNDG. 2 MAIN CAUSES RESULTED IN THIS SIT. 1) CHANGE IN LNDG RWY IN CLOSE, LEAVING US 'HIGH AND HOT.' 2) ACTIVATION OF TOGA CLOSE TO THE ALREADY SELECTED MISSED ALT OF 3000 FT WITH SUPERIOR ACFT PERFORMANCE, PREVENTED CAPTURED ALT LEVELOFF.
