RPTR MISUNDERSTANDS TWR CLRNC AND VARIES FROM INTENDED PATTERN.

Narrative

I WAS RETURNING FROM A MORNING SOLO TRAINING FLT AND WAS #1 IN THE SEQUENCE OF VFR ACFT ARRIVING IN THE PATTERN FROM THE N. MY INITIAL CLRNC INTO THE BRAVO AIRSPACE AT HONOLULU ARPT WAS A STANDARD CLRNC TO THE ARPT VIA THE NAVY/MARINE GOLF COURSE WHICH IS LOCATED JUST N OF THE ARPT AND IS JUST OUTSIDE THE VFR TFC PATTERN; IT IS USED AS THE GEOGRAPHICAL LOCATION FROM WHICH VFR ACFT ENTER THE DOWNWIND SEGMENT OF THE PATTERN. JUST PRIOR TO OVER FLYING THE GOLF COURSE; TWR CTL ISSUED INSTRUCTIONS TO MY ACFT TO EXTEND MY DOWNWIND SEGMENT AND THAT HE (TWR CTLR) WILL 'CALL MY TURN.' IT WAS AT THIS TIME I BELIEVE THAT THE MISUNDERSTANDING TOOK PLACE. INSTEAD OF TURNING INBOUND FOR A NORMAL DOWNWIND (L TURNS) TO A LNDG ON RWY 4L; I FLEW MY AIRPLANE ON A EXTENDED XWIND JUST OUTSIDE THE NORMAL PATTERN PATH AND LISTENING ON MY RADIO FOR THE TWR TO 'CALL MY TURN.' AFTER A FEW SECONDS HAD PASSED I REALIZED THAT I HAD MISUNDERSTOOD THE TWR'S INSTRUCTIONS AND MADE AN IMMEDIATE 180 DEG R TURN TO GET BACK ON THE CORRECT DOWNWIND. AS I CAME OUT OF MY TURN AND HAD ESTABLISHED MY DOWNWIND; A HIGH WING SINGLE ENG CESSNA (WHICH WAS APPARENTLY #2 IN THE SEQUENCE) WAS NOW XING IN FRONT OF MY FLT PATH. THERE WAS NO DANGER OF A MIDAIR COLLISION BEING THAT I HAD FLOWN SUCH A WIDE PATTERN AND THAT HE (THE CESSNA) WAS ENTERING THE PATTERN FROM THE NORMAL ENTRY POS. THE FACT REMAINED HOWEVER THAT I HAD MADE A MISTAKE WHICH NOW RESULTED IN 2 ACFT BEING ON THE DOWNWIND SEGMENT OF THE PATTERN AND BOTH WERE CLRED FOR THE SAME RWY. I SLOWED MY AIRPLANE DOWN TO INCREASE THE DISTANCE BTWN ME AND THE CESSNA AND DELAYED MY TURN TO BASE UNTIL THE CESSNA WAS OFF MY L WING. HOWEVER WHEN I HAD CROSSED THE NUMBERS OF RWY 4L ON SHORT FINAL; THE CESSNA HAD JUST BEGUN TAXIING OFF THE RWY AND THE TWR COMMENTED THAT THERE WAS LESS THAN A THOUSAND FT SEPARATION AT THAT MOMENT. I APPLIED A LITTLE SHORT FIELD LNDG TECHNIQUE AND LANDED MY AIRPLANE WITH ENOUGH SEPARATION TO SATISFY THE TWR. I REALIZED THAT IN THIS SIT THE PROB ORIGINATED WITH MY FAILURE TO UNDERSTAND THE INSTRUCTIONS FROM THE TWR. PERHAPS IN SOME DEGREE THE INSTRUCTIONS 'EXTEND YOUR DOWNWIND; I'LL CALL YOUR TURN;' FROM THE TWR GIVEN TO AN ACFT NOT YET ESTABLISHED ON THE DOWNWIND IS A CONTRIBUTING FACTOR. FOR IT MAY BE UNDERSTOOD TO SOME AS...'I'LL CALL YOUR TURN TO ENTER THE DOWNWIND LEG OF THE PATTERN; AND ONCE YOU'RE ESTABLISHED ON THE DOWNWIND I WANT YOU TO EXTEND IT.' CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED HE WAS FLYING A 4 PLACE AEROSPATIAL TAMPICO. HE SAID THERE IS HVY TFC OF BOTH AIRLINERS AND PVT AVIATION INTO HNL. ALSO; THERE IS USUALLY TURB. THE CLRNC 'I WILL CALL YOUR TURN' WAS MISUNDERSTOOD BECAUSE IT OCCURRED JUST AS HE WAS ABOUT TO TURN ON TO THE 45 TO THE DOWNWIND. IF 'I WILL CALL THE TURN' WERE GIVEN WHEN THE PLT WERE ON DOWNWIND THE FACT THE 'EXTEND YOUR DOWNWIND' NOT BEING HEARD WOULD NOT HAVE BEEN AS CRITICAL.
