Narrative:

Aircraft X was being vectored wbound to avoid arrival traffic sbound into tpa. Aircraft Y was not radar idented, climbing over zph airport on frequency for TA's. As aircraft Y passed about 11400 ft, traffic was issued to aircraft X. At that time, aircraft X advised he was getting a TCAS RA and was taking evasive action. Aircraft X then climbed to 12400 ft, while aircraft Y leveled off below him. After they passed, aircraft X advised he was returning to his assigned altitude and heading. Aircraft Y completed his climb to 12500 ft. This situation is a problem that has been reported previously numerous times. That is, jump aircraft climbing through traffic overflying on vectors or on the federal airway. I believe the only remedy is to have the jump aircraft move to another location, preferably to a much less congested area. In my opinion, it is only a matter of time before a midair collision occurs, before this dangerous operation is corrected.

Title: TPA TRACON CTLR EXPRESSED CONCERN REGARDING PARACHUTE ACFT CLBING THROUGH AIRWAY.

Narrative: ACFT X WAS BEING VECTORED WBOUND TO AVOID ARR TFC SBOUND INTO TPA. ACFT Y WAS NOT RADAR IDENTED, CLBING OVER ZPH ARPT ON FREQ FOR TA'S. AS ACFT Y PASSED ABOUT 11400 FT, TFC WAS ISSUED TO ACFT X. AT THAT TIME, ACFT X ADVISED HE WAS GETTING A TCAS RA AND WAS TAKING EVASIVE ACTION. ACFT X THEN CLBED TO 12400 FT, WHILE ACFT Y LEVELED OFF BELOW HIM. AFTER THEY PASSED, ACFT X ADVISED HE WAS RETURNING TO HIS ASSIGNED ALT AND HDG. ACFT Y COMPLETED HIS CLB TO 12500 FT. THIS SIT IS A PROB THAT HAS BEEN RPTED PREVIOUSLY NUMEROUS TIMES. THAT IS, JUMP ACFT CLBING THROUGH TFC OVERFLYING ON VECTORS OR ON THE FEDERAL AIRWAY. I BELIEVE THE ONLY REMEDY IS TO HAVE THE JUMP ACFT MOVE TO ANOTHER LOCATION, PREFERABLY TO A MUCH LESS CONGESTED AREA. IN MY OPINION, IT IS ONLY A MATTER OF TIME BEFORE A MIDAIR COLLISION OCCURS, BEFORE THIS DANGEROUS OP IS CORRECTED.
