Narrative:

While on a VFR training exercise, our C152 was approximately 7-9 mi southwest of westmoreland airport and outside of class D airspace. We began a diversion exercise towards indiana county airport, approximately 25 mi nne of westmoreland. I had instructed the student to report his position to tower (westmoreland) and ask for a class D airspace transition clearance since our projected route of flight may take us just into the westmoreland class D airspace. While he made his position report, I made sure we remained clear of the class D airspace and continued looking for traffic in the airport area. We received our transition clearance through the class D airspace and proceeded on course, taking us to the extreme western edge of the class D airspace. While approximately abeam the airfield, we noticed another aircraft in the area and took action to properly avoid it. It so happens that the aircraft was a commuter BE99 on a visual approach and was on downwind to base at the time. We saw and avoided him, but apparently his TCASII warning went off and he mentioned to tower that we were approximately 200 ft from his aircraft and he had to make a 30 degree bank to avoid us. Not so. We were more than 200 ft and made sure he was able to pass to our right, clear of us. I'm sure our slow airspeed and his fast airspeed contributed to his being upset at our proximity to him. When they contacted the tower, the tower mentioned that they didn't see us and expected us to be passing from the southeast. My student apparently misrpted our position from 7-9 mi southwest to 7-9 mi southeast. We were never southeast of the field, didn't cross the final approach course for the active runway 5, and remained well clear of the class D until receiving a transition clearance by the tower. The pilots of the BE99 felt we were too close while I know we saw the aircraft and took action to pass well clear. The only suggestion in this matter I can suggest is to have radar at class D airports for sits like this since tower couldn't see us and for anyone out there flying, better position reporting. Conditions were VFR in controled airspace.

Title: AN INSTRUCTOR AND HIS STUDENT IN A C152 GAVE AN INCORRECT POS RPT TO ATCT LCL CTLR AND THEN HAD AN NMAC WITH AN ACR BE99 ON APCH.

Narrative: WHILE ON A VFR TRAINING EXERCISE, OUR C152 WAS APPROX 7-9 MI SW OF WESTMORELAND ARPT AND OUTSIDE OF CLASS D AIRSPACE. WE BEGAN A DIVERSION EXERCISE TOWARDS INDIANA COUNTY ARPT, APPROX 25 MI NNE OF WESTMORELAND. I HAD INSTRUCTED THE STUDENT TO RPT HIS POS TO TWR (WESTMORELAND) AND ASK FOR A CLASS D AIRSPACE TRANSITION CLRNC SINCE OUR PROJECTED RTE OF FLT MAY TAKE US JUST INTO THE WESTMORELAND CLASS D AIRSPACE. WHILE HE MADE HIS POS RPT, I MADE SURE WE REMAINED CLR OF THE CLASS D AIRSPACE AND CONTINUED LOOKING FOR TFC IN THE ARPT AREA. WE RECEIVED OUR TRANSITION CLRNC THROUGH THE CLASS D AIRSPACE AND PROCEEDED ON COURSE, TAKING US TO THE EXTREME WESTERN EDGE OF THE CLASS D AIRSPACE. WHILE APPROX ABEAM THE AIRFIELD, WE NOTICED ANOTHER ACFT IN THE AREA AND TOOK ACTION TO PROPERLY AVOID IT. IT SO HAPPENS THAT THE ACFT WAS A COMMUTER BE99 ON A VISUAL APCH AND WAS ON DOWNWIND TO BASE AT THE TIME. WE SAW AND AVOIDED HIM, BUT APPARENTLY HIS TCASII WARNING WENT OFF AND HE MENTIONED TO TWR THAT WE WERE APPROX 200 FT FROM HIS ACFT AND HE HAD TO MAKE A 30 DEG BANK TO AVOID US. NOT SO. WE WERE MORE THAN 200 FT AND MADE SURE HE WAS ABLE TO PASS TO OUR R, CLR OF US. I'M SURE OUR SLOW AIRSPD AND HIS FAST AIRSPD CONTRIBUTED TO HIS BEING UPSET AT OUR PROX TO HIM. WHEN THEY CONTACTED THE TWR, THE TWR MENTIONED THAT THEY DIDN'T SEE US AND EXPECTED US TO BE PASSING FROM THE SE. MY STUDENT APPARENTLY MISRPTED OUR POS FROM 7-9 MI SW TO 7-9 MI SE. WE WERE NEVER SE OF THE FIELD, DIDN'T CROSS THE FINAL APCH COURSE FOR THE ACTIVE RWY 5, AND REMAINED WELL CLR OF THE CLASS D UNTIL RECEIVING A TRANSITION CLRNC BY THE TWR. THE PLTS OF THE BE99 FELT WE WERE TOO CLOSE WHILE I KNOW WE SAW THE ACFT AND TOOK ACTION TO PASS WELL CLR. THE ONLY SUGGESTION IN THIS MATTER I CAN SUGGEST IS TO HAVE RADAR AT CLASS D ARPTS FOR SITS LIKE THIS SINCE TWR COULDN'T SEE US AND FOR ANYONE OUT THERE FLYING, BETTER POS RPTING. CONDITIONS WERE VFR IN CTLED AIRSPACE.
