Fgt X on visual approach requested and was given overhead pattern from a visual approach. Second fgt also given the overhead approach, but first fgt made go around as the second aircraft was on break. Aircraft got in close proximity, tower controller thinks unsafe operation.

Narrative:
Fgt X was sequenced for a visual approach to land on runway 21 at colorado springs municipal airport. Fgt Y sequenced in trail for a visual approach to land on runway 21. Fgt X called the local controller and reported on a 5 mile final to runway 21. The local controller cleared fgt X to land and issued the winds. Fgt X asked for the initial altitude. The local controller asked fgt X if he wanted to go to the overhead pattern. Fgt X said yes. The local controller gave the initial altitude and instructions to break left at the departure end of the runway. The local controller then instructed fgt Y to enter initial at 7700 MSL and to break left at the departure end of the runway. Fgt X broke left and the local controller cleared him to land runway 21 and issued the winds. Fgt X acknowledged the clearance. Fgt X turned final and on short final told the local controller he was on the go. Both aircraft then entered left downwind the fgt Y on the break, the fgt X on his go round. There was no system error because of the definition of visual separation applied by the local controller, but the failure of the fgt X to follow ATC instructions led to both aircraft being in close proximity to each other and to the disruption of the traffic pattern and the approach sequences for other arriving aircraft.

Title: FGT X ON VISUAL APCH REQUESTED AND WAS GIVEN OVERHEAD PATTERN FROM A VISUAL APCH. SECOND FGT ALSO GIVEN THE OVERHEAD APCH, BUT FIRST FGT MADE GO AROUND AS THE SECOND ACFT WAS ON BREAK. ACFT GOT IN CLOSE PROX, TWR CTLR THINKS UNSAFE OPERATION.
Narrative: FGT X WAS SEQUENCED FOR A VISUAL APCH TO LAND ON RWY 21 AT COLORADO SPRINGS MUNICIPAL ARPT. FGT Y SEQUENCED IN TRAIL FOR A VISUAL APCH TO LAND ON RWY 21. FGT X CALLED THE LOCAL CTLR AND REPORTED ON A 5 MILE FINAL TO RWY 21. THE LOCAL CTLR CLRED FGT X TO LAND AND ISSUED THE WINDS. FGT X ASKED FOR THE INITIAL ALT. THE LOCAL CTLR ASKED FGT X IF HE WANTED TO GO TO THE OVERHEAD PATTERN. FGT X SAID YES. THE LOCAL CTLR GAVE THE INITIAL ALT AND INSTRUCTIONS TO BREAK LEFT AT THE DEP END OF THE RWY. THE LOCAL CTLR THEN INSTRUCTED FGT Y TO ENTER INITIAL AT 7700 MSL AND TO BREAK LEFT AT THE DEP END OF THE RWY. FGT X BROKE LEFT AND THE LOCAL CTLR CLRED HIM TO LAND RWY 21 AND ISSUED THE WINDS. FGT X ACKNOWLEDGED THE CLRNC. FGT X TURNED FINAL AND ON SHORT FINAL TOLD THE LOCAL CTLR HE WAS ON THE GO. BOTH ACFT THEN ENTERED LEFT DOWNWIND THE FGT Y ON THE BREAK, THE FGT X ON HIS GO ROUND. THERE WAS NO SYSTEM ERROR BECAUSE OF THE DEFINITION OF VISUAL SEPARATION APPLIED BY THE LOCAL CTLR, BUT THE FAILURE OF THE FGT X TO FOLLOW ATC INSTRUCTIONS LED TO BOTH ACFT BEING IN CLOSE PROX TO EACH OTHER AND TO THE DISRUPTION OF THE TFC PATTERN AND THE APCH SEQUENCES FOR OTHER ARRIVING ACFT.
