CLOSE PROX GA-SMA MIL-FGT IN NGF ATA.

Narrative

I AM A FLT INSTR AT FLT SCHOOL. ON 9/88 I DEPARTED HNL ON AN INSTRUCTION FLT. THE PLANNED ROUTE OF FLT WAS TO BE COUNTERCLOCKWISE AROUND OHAU; SOME LNDGS AT FORD ISLAND; THEN RETURN TO HNL. THE PLT I WAS CHKING OUT WAS A HIGHLY QUALIFIED GA PLT. WE DEPARTED THE HNL TCA TO THE E. AFTER HNL DEP CLRED US OUT OF THE TCA; WE CONTINUED OUR FLT COUNTERCLOCKWISE TO THE KANEOHE MARINE CORP AIR STATION. THERE WERE 2 VFR ROUTES PUBLISHED FOR XING; THE PREFERRED ROUTE AND THE ALTERNATE PREFERRED ROUTING (ENCLOSED MAP). APCHING THE KANEOHE ATA; IT WAS OBVIOUS THAT I WOULD NOT BE ABLE TO FLY THE PREFERRED ROUTE DUE TO CLOUDS. I REQUESTED THE ALTERNATE ROUTING. THE CLRNC WAS APPROVED AND I WAS TOLD TO MAINTAIN 500' OR BELOW. APCHING THE ARR PATH TO RWY 22; THE TWR ADVISED ME OF ARRIVING TFC AND TO PASS BEHIND. I NEVER SAW THE TFC UNTIL I WAS WELL PAST THE EXTENDED CENTERLINE OF RWY 22. WE FINALLY OBSERVED A FGT PASSING BEHIND AT ABOUT THE 5 O'CLOCK POS. DURING THE TRANSITION; I DO REMEMBER THE TWR DIRECTING ME TO TURN RIGHT FOR TFC AVOIDANCE; AT THAT TIME I RPTED OUR POS WELL CLR OF THE RWY CENTERLINE AND THE TWR TOLD ME TO CONTINUE. I ADVISED THE TWR I WAS CLR OF THE PATTERN AND THE CALL WAS ACKNOWLEDGED. NOW THAT I WAS CLR OF THE APCH PATTERN; I INSTRUCTED THE CHKOUT PLT TO START A CLB TO SAFE ALT THAT WOULD ALLOW US TO MAKE LAND IN CASE OF ENG PROBS. UNKNOWN TO ME AT THE TIME; THE FGT WAS BEING VECTORED ON A ROUTE AND ALT THAT WOULD BRING BOTH ACFT WITHIN THE SAME PROX. ALTHOUGH STILL IN CONTACT WITH THE TWR; I WAS NEVER ADVISED OF THE TFC. THE FGT WAS BEING CTLED BY KANEOHE GND RADAR ON A UHF FREQ; AND I WAS VHF. REVIEWING THE 2 ACFT FLT PATHS; IT APPEARS TO ME THAT GND RADAR COULD HAVE PREVENTED SUCH A CLOSE ENCOUNTER. SINCE THE FLT 9/88; THE ALTERNATE ROUTE HAS BEEN DELETED. I HAVE FURTHER INFO THAT THE ALTERNATE PREFERRED ROUTING HAD BEEN DELETED AS FAR BACK AS 7/88 FOR HAZARDOUS CONDITIONS TO FLTS ARRIVING AT THE AIR STATION. MY MISUNDERSTANDING ABOUT WHERE THE 500' RESTRICTION APPLIED WAS A DEFINITE FACTOR. THE TWR ISSUING A DELETED AND UNSAFE ROUTE OF FLT HAS TO BE A PRIMARY FACTOR. THE TWR'S FAILURE TO ADVISE ME OF KNOWN TFC. THE FAILURE OF GND RADAR TO ADJUST THE JET ROUTING AND ALT IN A MORE TIMELY FASHION I WOULD ALSO CONSIDER A PRIMARY CAUSE. THE PROFILE OF THE TRANSITION COULD BE MODIFIED TO GO DIRECTLY OVER THE FIELD SO AS TO AVOID THE DEP AND ARR AREAS.
