Narrative

I WAS CONDUCTING A SCOUTING OF THE LCL AREA WITH THE STUDENTS FOR THE PURPOSE OF FAMILIARIZING THEM WITH LCL LANDMARKS FOR THE PURPOSE OF AN UPCOMING FLYING MEET. AFTER COMPLETING OUR AREA SURVEY; WE APCHED TCL ARPT FROM ABOUT 10 NM NE FOR PURPOSE OF LNDG. AT ABOUT 7 MI NE; TCL TWR INSTRUCTED US TO ENTER THE L DOWNWIND FOR RWY 11. THE ENTRY TO THE TFC PATTERN PUT ME IN APPROX ALIGNMENT WITH RWY 22 FINAL APCH PATH. SHORTLY AFTER ATC'S INSTRUCTION TO ENTER TFC PATTERN; AN ACR LTT CALLED IN NE OF ARPT ON FINAL FOR RWY 22. ATC CALLED TFC TO ME; AND I ADVISED THEM OF MY PROX TO THE RWY 22 FINAL APCH COURSE. I FURTHER ADVISED TWR THAT I WOULD MANEUVER FURTHER TO THE W TO AVOID THE OTHER ACFT; WHICH WAS NOT VISIBLE AT THIS TIME. I INTENDED TO ENTER THE PATTERN AT APPROX A 90 DEG ANGLE; WHICH WOULD AVOID THE OTHER ACFT'S FLT PATH. UPON BEGINNING THE MANEUVER (R TURN TO THE W); THE ACR PASSED OVER AND SLIGHTLY TO THE R OF OUR ACFT. ACR WAS FIRST SIGHTED BY STUDENT OBSERVING FROM L SEAT OF OUR ACFT THROUGH OVERHEAD SKYLIGHT. THERE WAS NO TIME TO TAKE EVASIVE ACTION AND NO EVASIVE ACTION OR DEV OF FLT PATH WAS OBSERVED OF THE ACR CREW. BOTH ACFT CONTINUED AND LANDED WITHOUT FURTHER INCIDENT. SHORTLY BEFORE LNDG; I ASKED TWR IF ACR CREW SAW US AND THEY SAID THAT ACR CREW SAID THAT WE 'PASSED RIGHT UNDER THEM.' I FEEL THAT CONTRIBUTING FACTORS WERE THE HIGH WING OF OUR ACFT OBSTRUCTING OUR VIEW ABOVE AND BEHIND OUR ACFT; LACK OF RADAR CTL AT TCL TWR; AND THE 2 ACFT APCHING ARPT FROM APPROX SAME DIRECTION. TO PREVENT ANY FUTURE OCCURRENCES OF THIS TYPE; I FEEL IT WOULD BE HELPFUL FOR TWRS WITHOUT ATIS BROADCASTS TO ADVISE PLTS OF THE RWYS IN USE SO THESE AREAS COULD BE AVOIDED. I ALSO PLAN TO MAINTAIN EXTRA CARE WITH REGARD TO A PARTICULAR ACFT'S 'BLIND SPOTS.'
