Narrative:

At or about XA22 local time, I relieved the controller on the fmy hi sector. The sector at that time was involved in a heavy traffic situation, with bad WX and frequency congestion. Light transport was approximately 15 mi southeast of fmy on an observed heading of 160 degrees. His altitude was FL240. Air carrier large transport also at FL240 was about 5 mi southeast of fmy on the fortl 1 arrival (about a 120 degree heading). To the best of my knowledge light transport was issued a clearance for the cce 1 arrival by the previous controller. The tapes show this clearance was not issued. Light transport was observed by me turning eastbound. I asked light transport to say heading. Light transport said he was heading 115 degrees. At this point, when light transport finished his transmission, the microphone was stuck in the transmit mode. I attempted 4 times to issue a clearance to light transport to turn south and to descend to FL180. The aircraft did not receive this clearance due to his stuck microphone. Finally, after fixing his stuck microphone, light transport accepted the clearance. Air carrier-large transport, who was in transition to another frequency, was turned to a 010 degree heading. After a couple of tries to raise him on his newly assigned frequency. The aircraft passed within 4 1/2 mi of each other. Also, an additional contributing factor is the fact that the pilot of light transport does not have a nos chart showing the cce 1 arrival. This is an arrival that has been operational since 10/88 and still is not published on the nos charts. I believe the stuck microphone was the main reason for this situation. I have no idea to help stop a stuck microphone from happening in the future.

Title: LESS THAN STANDARD SEPARATION BETWEEN ACR-LGT AND GA-LTT. OPERATIONAL ERROR. STUCK MICROPHONE.

Narrative: AT OR ABOUT XA22 LCL TIME, I RELIEVED THE CTLR ON THE FMY HI SECTOR. THE SECTOR AT THAT TIME WAS INVOLVED IN A HEAVY TFC SITUATION, WITH BAD WX AND FREQ CONGESTION. LTT WAS APPROX 15 MI SE OF FMY ON AN OBSERVED HDG OF 160 DEGS. HIS ALT WAS FL240. ACR LGT ALSO AT FL240 WAS ABOUT 5 MI SE OF FMY ON THE FORTL 1 ARR (ABOUT A 120 DEG HDG). TO THE BEST OF MY KNOWLEDGE LTT WAS ISSUED A CLRNC FOR THE CCE 1 ARR BY THE PREVIOUS CTLR. THE TAPES SHOW THIS CLRNC WAS NOT ISSUED. LTT WAS OBSERVED BY ME TURNING EBND. I ASKED LTT TO SAY HDG. LTT SAID HE WAS HDG 115 DEGS. AT THIS POINT, WHEN LTT FINISHED HIS XMISSION, THE MIC WAS STUCK IN THE XMIT MODE. I ATTEMPTED 4 TIMES TO ISSUE A CLRNC TO LTT TO TURN S AND TO DSND TO FL180. THE ACFT DID NOT RECEIVE THIS CLRNC DUE TO HIS STUCK MIC. FINALLY, AFTER FIXING HIS STUCK MIC, LTT ACCEPTED THE CLRNC. ACR-LGT, WHO WAS IN TRANSITION TO ANOTHER FREQ, WAS TURNED TO A 010 DEG HDG. AFTER A COUPLE OF TRIES TO RAISE HIM ON HIS NEWLY ASSIGNED FREQ. THE ACFT PASSED WITHIN 4 1/2 MI OF EACH OTHER. ALSO, AN ADDITIONAL CONTRIBUTING FACTOR IS THE FACT THAT THE PLT OF LTT DOES NOT HAVE A NOS CHART SHOWING THE CCE 1 ARR. THIS IS AN ARR THAT HAS BEEN OPERATIONAL SINCE 10/88 AND STILL IS NOT PUBLISHED ON THE NOS CHARTS. I BELIEVE THE STUCK MIC WAS THE MAIN REASON FOR THIS SITUATION. I HAVE NO IDEA TO HELP STOP A STUCK MIC FROM HAPPENING IN THE FUTURE.
