Narrative:

My student and I were returning from our second dual x-country. He was under the hood, I was talking him into the pattern simulating a radar approach. During our attempt to enter the pattern and land we had several conflicts due to many factors. I removed the hood from my student during the first pattern entry on base. The conditions were VMC with a low sun in our eyes as we flew inbound from the east. It was later estimated that for approximately 10 mins at the time of our arrival there were 10-15 aircraft in the pattern, entering or ready for takeoff. Mckinney is a very popular place for touch and goes. It is also a reliever for dallas, thus trners mix it up with homebuilts, twins, high performance singles, aerobatic planes and helicopters. Position 1: we entered the pattern normally. Inbound we noticed an aircraft climbing on crosswind, we turned downwind. No conflict. We were ahead and slightly farther out. I noticed no other traffic other than 2 aircraft waiting to depart. Position 2: on base, turning to final, I noticed we had cut off another aircraft below and behind on final, I never saw him. I elected to go around and initiated a climb, my student took off his hood. No conflict. Position 3: as we flew down the runway and angled out to a close upwind to watch for traffic, we noticed an aircraft climbing off the runway, had we not angled out it could have been serious but this time no conflict. We planned to follow this aircraft on a crosswind when he made an improper turn into us! We turned and circled back to upwind to avoid him. Position 4: we turned a long crosswind, monitoring 2 aircraft in front of us. Once on crosswind we saw a low wing small aircraft climbing over and in front of us. Where did he come from? He never saw us but we descended and turned to the right to avoid a conflict. Position 5: we reentered the pattern, ahead of another trner on a close downwind. We angled out and let him land first then we landed. Whew!

Title: TWO SMAS HAVE NMAC IN TRAFFIC PATTERN AT TKI.

Narrative: MY STUDENT AND I WERE RETURNING FROM OUR SEC DUAL X-COUNTRY. HE WAS UNDER THE HOOD, I WAS TALKING HIM INTO THE PATTERN SIMULATING A RADAR APCH. DURING OUR ATTEMPT TO ENTER THE PATTERN AND LAND WE HAD SEVERAL CONFLICTS DUE TO MANY FACTORS. I REMOVED THE HOOD FROM MY STUDENT DURING THE FIRST PATTERN ENTRY ON BASE. THE CONDITIONS WERE VMC WITH A LOW SUN IN OUR EYES AS WE FLEW INBND FROM THE E. IT WAS LATER ESTIMATED THAT FOR APPROX 10 MINS AT THE TIME OF OUR ARR THERE WERE 10-15 ACFT IN THE PATTERN, ENTERING OR READY FOR TKOF. MCKINNEY IS A VERY POPULAR PLACE FOR TOUCH AND GOES. IT IS ALSO A RELIEVER FOR DALLAS, THUS TRNERS MIX IT UP WITH HOMEBUILTS, TWINS, HIGH PERFORMANCE SINGLES, AEROBATIC PLANES AND HELIS. POS 1: WE ENTERED THE PATTERN NORMALLY. INBND WE NOTICED AN ACFT CLBING ON XWIND, WE TURNED DOWNWIND. NO CONFLICT. WE WERE AHEAD AND SLIGHTLY FARTHER OUT. I NOTICED NO OTHER TFC OTHER THAN 2 ACFT WAITING TO DEPART. POS 2: ON BASE, TURNING TO FINAL, I NOTICED WE HAD CUT OFF ANOTHER ACFT BELOW AND BEHIND ON FINAL, I NEVER SAW HIM. I ELECTED TO GO AROUND AND INITIATED A CLB, MY STUDENT TOOK OFF HIS HOOD. NO CONFLICT. POS 3: AS WE FLEW DOWN THE RWY AND ANGLED OUT TO A CLOSE UPWIND TO WATCH FOR TFC, WE NOTICED AN ACFT CLBING OFF THE RWY, HAD WE NOT ANGLED OUT IT COULD HAVE BEEN SERIOUS BUT THIS TIME NO CONFLICT. WE PLANNED TO FOLLOW THIS ACFT ON A XWIND WHEN HE MADE AN IMPROPER TURN INTO US! WE TURNED AND CIRCLED BACK TO UPWIND TO AVOID HIM. POS 4: WE TURNED A LONG XWIND, MONITORING 2 ACFT IN FRONT OF US. ONCE ON XWIND WE SAW A LOW WING SMA CLBING OVER AND IN FRONT OF US. WHERE DID HE COME FROM? HE NEVER SAW US BUT WE DSNDED AND TURNED TO THE R TO AVOID A CONFLICT. POS 5: WE REENTERED THE PATTERN, AHEAD OF ANOTHER TRNER ON A CLOSE DOWNWIND. WE ANGLED OUT AND LET HIM LAND FIRST THEN WE LANDED. WHEW!
