SMA IS CLRED BEHIND A 757 BUT REFUSES CLRNC DUE TO POS BELOW THE ACFT. ASSIGNED PARALLEL RWY.

Narrative

I HAD RECEIVED SEVERAL VECTORS DUE TO THE AMOUNT OF TFC AT SNA. ONCE ESTABLISHED ON DOWNWIND. JUST PRIOR TO TURNING BASE THE TWR GAVE ME A 'L 360 DEG TURN AND RPT RE-ESTABLISH ON DOWNWIND.' AFTER ACKNOWLEDGING AND COMPLETING THAT DIRECTION I WAS GIVEN: 'FOLLOW THE 757. CLR TO LAND RWY 19R.' I REFUSED TO FOLLOW THE 757 AS HE WAS ABOVE MY ALT AND THIS WOULD MEAN XING AND POSSIBLY FOLLOWING IN HIS WAVE TURB. I THEN REQUEST RWY 19L AND WAS CLRED. I IMMEDIATELY CLBED TO AN ALT I BELIEVED TO BE WELL ABOVE GS AND ENTERED THE FINAL FOR RWY 19L. ON FINAL AGAIN; A 757 WAS TAXIING FOR TKOF ACROSS THE APCH OF RWY 19L. I WAS CAUTIONED WAKE TURB FROM THE TAXIING 757. I LANDED LONG. I WILL MAKE AN EFFORT TO DISCUSS THIS WITH THE SNA TWR SUPVR ON JUL/XX/94. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATES HE HAD HIS MEETING WITH THE TWR SUPVR AND RECEIVED VERY GRACIOUS TREATMENT. THE PROB HOWEVER; CONTINUES TO OCCUR DUE TO THE RULES THAT REQUIRE PLT RESPONSIBILITY TO SEE AND AVOID THE TFC AND ITS WAKE TURB. RPTR HAD THE FEELING THAT THE CTLRS ARE FRUSTRATED BY THE SIT AS MUCH AS PLTS BUT ARE BOUND BY THE NEED TO KEEP THE TFC FLOW AT THE HIGHEST RATE POSSIBLE. LCL PLTS HAVE RECEIVED NUMEROUS LETTERS FROM THE FAA AND PLT GROUPS REGARDING THE NEED FOR CAUTION BEHIND THE 757 ACFT. INDEED THE FLT PATTERN IS WITHIN A 1/4 MI RADIUS OF THE ACCIDENT THAT OCCURRED WITH 757 WAKE TURB; SO PLTS ARE VERY AWARE OF THE PROB. NO DOUBT THE CTLRS ARE AS WELL. RPTR DISTRESSED BECAUSE THE PRACTICE OF CLRING ACFT BEHIND THE 757 AT SUCH CLOSE RANGE CONTINUES -- AT THIS VERY MOMENT AS RPTR EXPLAINED THAT ACTIVITY IS GOING ON. IT IS A NO WIN SIT. RPTR ASSURED THAT HE DOES NOT THINK IN A 'LIABILITY' SENSE; BUT WITH A CONCERN FOR SAFETY. PRIMARILY FOR THE NEW PLTS WHO WOULD NOT HAVE THE KNOWLEDGE TO REFUSE A CLRNC WHICH MIGHT PUT THEM IN JEOPARDY. SUPPLEMENTAL CALL BACK INDICATED RPTR WAS APPROX 1 MI AWAY BUT OPPOSITE DIRECTION FROM 757 TFC. HE HAD APCH PLATE ON LAP AS ALWAYS AND NOTED APCH ALT OF INCOMING TFC SO HE CLBED TO 1800 FT. RPTR INDICATED WILLINGNESS TO PARTICIPATE IN STRUCTURED CALL BACK STUDY.
