PRC TWR CTLR FAILED TO COMMUNICATE WITH TFC ON BASE; RESULTING IN DIRECTED TURN AWAY FROM THE TFC PATTERN; TIPH PROCS CITED AS CONTRIBUTORY.

Narrative

I WAS WORKING THE LCL 1 POS ON RWY 21L WITH THE LCL 2 POS OPEN DURING MODERATE TFC. I HAD ALREADY GIVEN A CESSNA ON L DOWNWIND A LNDG CLRNC AND HAD SEVERAL OTHER ACFT IN THE PATTERN WHEN AN ACFT CALLED FOR DEP. A SEMINOLE JUST CROSSED THE LNDG THRESHOLD AND I KNEW I COULD GET THE DEP OUT IF I UTILIZED TIPH. THE LNDG CESSNA HAD ALREADY TURNED BASE AND I INSTRUCTED HIM TO CANCEL LNDG CLRNC; CONTINUE L BASE; TFC HOLDING IN POS. I INSTRUCTED THE DEP; TFC L BASE; RWY 21 POS AND HOLD AND AS SOON AS THE PREVIOUS ARR EXITED THE RWY I GAVE THE CESSNA THAT WAS IN POS TKOF CLRNC. I LOOKED OUT TO SEE THE CESSNA ON BASE APPARENTLY OVERSHOOT FINAL AND ADVISED HIM AS SUCH. HE RESPONDED THAT I INSTRUCTED HIM TO CONTINUE ON BASE. THE LCL 2 CTLR HAD MANY ACFT IN THE PATTERN FOR RWY 21R AND I QUICKLY HAD THE CESSNA TURN AWAY FROM THE ARPT AND ENTER A R DOWNWIND FOR RWY 21L. I COORD WITH THE LCL 2 CTLR AND RE-SEQUENCED THE CESSNA INTO THE ARRS FOR RWY 21L. AFTER THE CESSNA SAFELY LANDED; I BRIEFLY TOLD THE PLT THAT MY INSTRUCTIONS WERE NOT CLR; THAT I WAS SORRY; AND I WILL CHANGE MY PHRASEOLOGY FOR THAT SIT. THE PLT RESPONDED THAT HE WAS CONCERNED ABOUT FLYING INTO THE R DOWNWIND TFC BUT WAS JUST FOLLOWING OUR INSTRUCTIONS. I ADVISED HIM THAT HE SHOULD ALWAYS ASK FOR CLARIFICATION IF THERE IS EVER ANYTHING THAT IS UNCLR OR THAT HE HAS A CONCERN ABOUT. I BELIEVE THAT IF WE WERE STILL UTILIZING THE OLD TIPH RULES THAT THIS INCIDENT NEVER WOULD HAVE HAPPENED. THE RIDICULOUS REQUIREMENT THAT WE CAN ONLY PUT AN ACFT INTO POS WITH NO OTHER ACFT CLRED; ESPECIALLY AT A VFR ARPT; DOES NOTHING TO ENSURE THAT THERE WILL NOT BE A FLYOVER. EXTRA EYES IN THE CAB TO MONITOR THE TFC AND WATCH FOR MISTAKES IS THE BEST ANSWER FOR PREVENTING INCURSIONS OR ACCIDENTS. THE NEW TIPH RULES ACTUALLY RELAX THE REQUIREMENT TO HAVE EXTRA STAFFING IN THE CAB WHEN USING TIPH. WE CAN NOW USE TIPH WHEN THERE IS NOBODY BEHIND US TO ASSIST. THE NEW RULES HAVE LED TO MANY GAR'S BECAUSE THE CTLRS FORGET TO CLR THE ACFT ON FINAL TO LAND AFTER UTILIZING TIPH TO GET A DEP OUT. THESE NEW TIPH PROCS ARE YET ANOTHER EXAMPLE OF POOR PROCS DEVELOPED WITHOUT INPUT FROM THE CTLRS.
