SMA X UNCOORD UNAUTH TURN IN ATA. SMA X CONFLICT WITH SMA Y. SEE AND AVOID CONCEPT.

Narrative

I WAS WORKING THE LCL CTL POS IN THE PANAMA CITY (PFN) FL; ATCT. SMA X DEPARTED RWY 14; IFR; ON AN ASSIGNED HDG ON 230 DEGS CLBING TO 5000 FT. 2 SMA'S WERE W OF PFN; VFR; ENTERING A R BASE TO RWY 14. I OBSERVED SMA X 2 1/2 MI SSW OF PFN STARTING A TURN TO THE WNW AT 1500 FT. I CALLED THE APCH CTLR AT TYNDALL AFB RAPCON AND ASKED WHAT THEY WERE DOING WITH SMA X AND ADVISED HIM OF THE TWR TFC THAT WAS ENTERING A R BASE TO RWY 14. THEY SAID SMA X WAS DIVERTING AROUND WX. SMA X WAS HDG DIRECTLY TOWARDS SMA Y AND I ISSUED A TFC CALL TO SMA Y WHO LATER RPTED HIS ALT WAS BTWN 1100-1500 FT. DURING THIS TIME SMA X ALT INDICATED 1500 FT. SMA X CONTINUED WNW AND SMA Y LANDED ON RWY 14 WITHOUT FURTHER INCIDENT. THE REASON THIS EVENT OCCURRED IS THE TYNDALL AFB APCH CTLR ALLOWED SMA X TO DEVIATE FOR WX WITHOUT FIRST COORDINATING WITH THE TWR CTLR AT PFN. THE PANAMA CITY ATCT/TYNDALL RAPCON LOA CLRLY STATES THAT TYNDALL RAPCON MAY TURN ACFT AS LONG AS THE TURN TAKES THE ACFT AWAY FROM PANAMA CITY ATCT TFC PATTERNS. TYNDALL RAPCON HAS SHOWN A HISTORY OF FAILURE TO COORDINATE WITH PANAMA CITY ATCT FOR ACFT THAT ARE ENTERING; DEPARTING OR TRANSITIONING THROUGH THE PANAMA CITY ATA. THIS DEFICIENCY MUST BE CORRECTED TO AVOID A POSSIBLE MIDAIR COLLISION IN THE FUTURE.
