A BE02 CREW RECEIVES A TCASI TA FROM AN F16 CHARGING IN FROM THE 4 TO 5 O'CLOCK POS; SAME ALT. F16 DOES A WING OVER AND DIVES AWAY FROM THE BE02. ZAB ADMITTED TO NO KNOWLEDGE OF THE INCIDENT OTHER THAN RPTING LOWER TFC.

Narrative

WE WERE ON THE FOSSEL 3 ARR INTO PHP LEVEL AT 11000 FT WHEN THE TCASI GAVE A TA. TFC WAS INDICATED AT OUR 3-4 O'CLOCK POS WITHIN 1000 FT OF OUR ALT. APCHING RAPIDLY; I LOOKED; LOCATED A FAINT EXHAUST/SMOKE TRAIL AND THEN VISUALLY LOCATED THE ACFT. IT APPEARED TO BE MANEUVERING DIRECTLY TOWARD US AT A HIGH RATE OF CLOSURE. IT THEN BANKED (BROKE) TO THE L IN EXCESS OF 60 DEG OF BANK ANGLE. THE F16 THEN ROLLED INVERTED AND DSND AT A HIGH RATE OF DSCNT. THIS WAS THE POINT WHEN I WAS ABLE TO DISTINCTLY MAKE OUT THE ACFT AS AN F16. CTR THEN HANDED US OFF TO PHP APCH. PRIOR TO SWITCHING WE LET HIM KNOW THAT AN F16 HAD COME CLOSE TO US; WE HAD RECEIVED A TCASI TA AND THAT THE TFC HAD ROLLED INVERTED AND MANEUVERED OUT AWAY FROM US. THE CAPT HAD BEEN TALKING (PNF) BUT BECAUSE I HAD SEEN THE F16 I WANTED TO SAY SOMETHING TO CTR TO DESCRIBE THE SIT. HE HAD A TARGET ON HIS SCREEN IN OUR VICINITY BUT BY NOW WAS 2000-4000 FT BELOW OUR ALT. I BELIEVE CTR FELT THERE WAS NOTHING HE COULD DO SO HE DID NOT PURSUE THE MATTER BEYOND SAYING THERE WAS A TARGET DOWN LOW. IT IS MY BELIEF THAT THE F16 WAS TARGETING AND TRACKING US. I WOULD IMAGINE THAT WITH TCASII WE WOULD HAVE GOTTEN AN RA. THE ENCOUNTER WAS POINTLESS AND UNCALLED FOR IN VERY BUSY AIRSPACE. WHILE THIS CAUSED SOME EXCITEMENT IT HAD NO AFFECT ON OUR PERFORMANCE AS A CREW.
