Narrative:

On sunday, august, at approximately PM00 local, 1 of my students and I had taken off on runway 5 and entered the downwind for left traffic. While approaching the midfield downwind I noticed the headlights of an aircraft flying directly toward us. Taking control of the aircraft from the student, I closed the throttle and began a diving right turn. We had been at the correct pattern altitude of 1500 ft MSL. When the plane passed overhead and to the left we had lost approximately 300 ft. Our pattern ground track was over the approach end for runway 14 which is about 1500 ft from the runway we were using. As I began the evasive maneuver the tower transmitted an odd traffic advisory. 'Small aircraft X do you have the traffic.' since I was unaware that there was expected to be traffic flying directly at us while on the downwind leg, this call seems rather odd. 'I have a jet or a large twin flying straight at me,' I responded. 'We aren't talking to them.' the tower called back. After we dove away to the right, I asked the student to regain control and resume the left hand pattern. The tower asked us to then extend the downwind leg and then requested we leave the air traffic area and depart to the west. The tower was receiving a lot of incoming traffic and I assumed they also wanted us to calm ourselves. I didn't follow the communications after our near miss very closely, but I had sounded like the tower was in touch with this twin, an small transport Y, who had not idented the airport during his approach and had given poor position reports. The tower was working with the other aircraft prior to its incursion into our pattern and later cleared them to land. Why we were sent out of the air traffic area, and not brought back in for 10 min, I'm not sure.

Title: NMAC IN THE TFC PATTERN BTWN SMA AND SMT, OPPOSITE DIRECTION TFC.

Narrative: ON SUNDAY, AUGUST, AT APPROX PM00 LCL, 1 OF MY STUDENTS AND I HAD TAKEN OFF ON RWY 5 AND ENTERED THE DOWNWIND FOR L TFC. WHILE APCHING THE MIDFIELD DOWNWIND I NOTICED THE HEADLIGHTS OF AN ACFT FLYING DIRECTLY TOWARD US. TAKING CTL OF THE ACFT FROM THE STUDENT, I CLOSED THE THROTTLE AND BEGAN A DIVING R TURN. WE HAD BEEN AT THE CORRECT PATTERN ALT OF 1500 FT MSL. WHEN THE PLANE PASSED OVERHEAD AND TO THE L WE HAD LOST APPROX 300 FT. OUR PATTERN GND TRACK WAS OVER THE APCH END FOR RWY 14 WHICH IS ABOUT 1500 FT FROM THE RWY WE WERE USING. AS I BEGAN THE EVASIVE MANEUVER THE TWR TRANSMITTED AN ODD TFC ADVISORY. 'SMA X DO YOU HAVE THE TFC.' SINCE I WAS UNAWARE THAT THERE WAS EXPECTED TO BE TFC FLYING DIRECTLY AT US WHILE ON THE DOWNWIND LEG, THIS CALL SEEMS RATHER ODD. 'I HAVE A JET OR A LARGE TWIN FLYING STRAIGHT AT ME,' I RESPONDED. 'WE AREN'T TALKING TO THEM.' THE TWR CALLED BACK. AFTER WE DOVE AWAY TO THE R, I ASKED THE STUDENT TO REGAIN CTL AND RESUME THE L HAND PATTERN. THE TWR ASKED US TO THEN EXTEND THE DOWNWIND LEG AND THEN REQUESTED WE LEAVE THE ATA AND DEPART TO THE W. THE TWR WAS RECEIVING A LOT OF INCOMING TFC AND I ASSUMED THEY ALSO WANTED US TO CALM OURSELVES. I DIDN'T FOLLOW THE COMS AFTER OUR NEAR MISS VERY CLOSELY, BUT I HAD SOUNDED LIKE THE TWR WAS IN TOUCH WITH THIS TWIN, AN SMT Y, WHO HAD NOT IDENTED THE ARPT DURING HIS APCH AND HAD GIVEN POOR POS RPTS. THE TWR WAS WORKING WITH THE OTHER ACFT PRIOR TO ITS INCURSION INTO OUR PATTERN AND LATER CLRED THEM TO LAND. WHY WE WERE SENT OUT OF THE ATA, AND NOT BROUGHT BACK IN FOR 10 MIN, I'M NOT SURE.
