Narrative:

I was working flight director, ground control, clearance delivery at eyw. I taxied small aircraft X PA28 VFR to runway 9. As X was taxiing wbound on the parallel taxiway, I observed Y helicopter inbound from southwest. I issued X the helicopter traffic from southwest, and, since I had not received coordination from local, I told X to continue taxiing and that helicopter would pass behind him. Per 7110.65 in helicopter operations, helicopter's are supposed to remain clear of all fixed winged aircraft, and since I was working ground control, the taxiway belonged to me. After advising X about the helicopter, I observed Y taxiing eastbound on my taxiway (opposite direction to X) without having received coordination approval from me. Y then turned slightly south and proceeded to park on the diagonal taxiway. X stopped taxiing and then continued to taxi wbound when Y moved. No further incident occurred. However, after this situation, local controller became upset and told me he had coordinated the operation and had received approval. I told him that I did not hear him coordinate this operation, and that if I had heard and approved the coordination, I would never have issued X taxi instructions and informed X that Y would pass behind him.

Title: SMA X HAD CONFLICT WITH HELI Y WHILE TAXIING TO RWY. SEE AND AVOID CONCEPT.

Narrative: I WAS WORKING FLT DIRECTOR, GND CTL, CLRNC DELIVERY AT EYW. I TAXIED SMA X PA28 VFR TO RWY 9. AS X WAS TAXIING WBOUND ON THE PARALLEL TXWY, I OBSERVED Y HELI INBOUND FROM SW. I ISSUED X THE HELI TFC FROM SW, AND, SINCE I HAD NOT RECEIVED COORD FROM LCL, I TOLD X TO CONTINUE TAXIING AND THAT HELI WOULD PASS BEHIND HIM. PER 7110.65 IN HELI OPS, HELI'S ARE SUPPOSED TO REMAIN CLR OF ALL FIXED WINGED ACFT, AND SINCE I WAS WORKING GND CTL, THE TXWY BELONGED TO ME. AFTER ADVISING X ABOUT THE HELI, I OBSERVED Y TAXIING EBOUND ON MY TXWY (OPPOSITE DIRECTION TO X) WITHOUT HAVING RECEIVED COORD APPROVAL FROM ME. Y THEN TURNED SLIGHTLY S AND PROCEEDED TO PARK ON THE DIAGONAL TXWY. X STOPPED TAXIING AND THEN CONTINUED TO TAXI WBOUND WHEN Y MOVED. NO FURTHER INCIDENT OCCURRED. HOWEVER, AFTER THIS SIT, LCL CTLR BECAME UPSET AND TOLD ME HE HAD COORDINATED THE OP AND HAD RECEIVED APPROVAL. I TOLD HIM THAT I DID NOT HEAR HIM COORDINATE THIS OP, AND THAT IF I HAD HEARD AND APPROVED THE COORD, I WOULD NEVER HAVE ISSUED X TAXI INSTRUCTIONS AND INFORMED X THAT Y WOULD PASS BEHIND HIM.
