Narrative:

On a visual approach to runway 30L at houston hobby, approximately 10 mi out, houston approach asked me my airspeed. I was in a descent for landing and replied, '160 KTS.' he asked if I could maintain that till final and I replied that 'I would do my best.' approach was also working a medical volunteer flight to runway 30L. Approach switched me to the tower and I was cleared to land runway 30L. I could tell from radio xmissions that volunteer flight was not happy with the landing sequence or spacing as he was cleared to land behind me. I knew spacing was tight so I decided to exit at the first taxiway I could safely make, even though it was inconvenient to my destination. My thinking was to let the volunteer flight get to his destination as quickly as possible even though it meant more taxiing for me. As I was starting to exit runway 30L the controller asked me where I was parking and I told him on the west side. He told me to continue down the runway and exit at taxiway Q and 'to expedite.' I acknowledged the above and proceeded on runway 30L. At this point spacing with volunteer flight was getting worse so the controller called me asking me to turn left at the next taxiway. Unfortunately he used the incorrect call sign 'abcdx.' my full and correct call sign is 'abcdy.' he had mixed up the 'Y' with the 'X.' as houston hobby has 4 runways I did not think the controller was talking to me when he repeated the instruction to turn left at the next taxiway again using 'abcdx.' after the 2ND or 3RD call of 'abcdx,' I realized he meant 'abcdy.' in the meantime with the tight spacing volunteer flight requested a sidestep to runway 30R and landed safely. I have read that accidents are usually caused by a chain of events. This was reinforced by this experience. Had approach control sent volunteer flight ahead of me, had I performed a normal rollout and waited for the controller to call my turn, had the controller used my correct call sign all of this would have been avoided.

Title: BE33 LNDG HOU IS MISIDENTED BY ATC RESULTING SUCCEEDING TFC HAVING TO LAND ON PARALLEL RWY.

Narrative: ON A VISUAL APCH TO RWY 30L AT HOUSTON HOBBY, APPROX 10 MI OUT, HOUSTON APCH ASKED ME MY AIRSPD. I WAS IN A DSCNT FOR LNDG AND REPLIED, '160 KTS.' HE ASKED IF I COULD MAINTAIN THAT TILL FINAL AND I REPLIED THAT 'I WOULD DO MY BEST.' APCH WAS ALSO WORKING A MEDICAL VOLUNTEER FLT TO RWY 30L. APCH SWITCHED ME TO THE TWR AND I WAS CLRED TO LAND RWY 30L. I COULD TELL FROM RADIO XMISSIONS THAT VOLUNTEER FLT WAS NOT HAPPY WITH THE LNDG SEQUENCE OR SPACING AS HE WAS CLRED TO LAND BEHIND ME. I KNEW SPACING WAS TIGHT SO I DECIDED TO EXIT AT THE FIRST TXWY I COULD SAFELY MAKE, EVEN THOUGH IT WAS INCONVENIENT TO MY DEST. MY THINKING WAS TO LET THE VOLUNTEER FLT GET TO HIS DEST AS QUICKLY AS POSSIBLE EVEN THOUGH IT MEANT MORE TAXIING FOR ME. AS I WAS STARTING TO EXIT RWY 30L THE CTLR ASKED ME WHERE I WAS PARKING AND I TOLD HIM ON THE W SIDE. HE TOLD ME TO CONTINUE DOWN THE RWY AND EXIT AT TXWY Q AND 'TO EXPEDITE.' I ACKNOWLEDGED THE ABOVE AND PROCEEDED ON RWY 30L. AT THIS POINT SPACING WITH VOLUNTEER FLT WAS GETTING WORSE SO THE CTLR CALLED ME ASKING ME TO TURN L AT THE NEXT TXWY. UNFORTUNATELY HE USED THE INCORRECT CALL SIGN 'ABCDX.' MY FULL AND CORRECT CALL SIGN IS 'ABCDY.' HE HAD MIXED UP THE 'Y' WITH THE 'X.' AS HOUSTON HOBBY HAS 4 RWYS I DID NOT THINK THE CTLR WAS TALKING TO ME WHEN HE REPEATED THE INSTRUCTION TO TURN L AT THE NEXT TXWY AGAIN USING 'ABCDX.' AFTER THE 2ND OR 3RD CALL OF 'ABCDX,' I REALIZED HE MEANT 'ABCDY.' IN THE MEANTIME WITH THE TIGHT SPACING VOLUNTEER FLT REQUESTED A SIDESTEP TO RWY 30R AND LANDED SAFELY. I HAVE READ THAT ACCIDENTS ARE USUALLY CAUSED BY A CHAIN OF EVENTS. THIS WAS REINFORCED BY THIS EXPERIENCE. HAD APCH CTL SENT VOLUNTEER FLT AHEAD OF ME, HAD I PERFORMED A NORMAL ROLLOUT AND WAITED FOR THE CTLR TO CALL MY TURN, HAD THE CTLR USED MY CORRECT CALL SIGN ALL OF THIS WOULD HAVE BEEN AVOIDED.
