Narrative:

I was on my first training flight with a particular student that I hadn't flown with before. I was going to evaluate his readiness for his private pilot check ride. We had completed the before takeoff checklist. While going through the runup, we had heard an small transport pilot make an 8 mi out and 4 mi out radio call, inbound for landing and eventually an abeam-the-field call. The last call was a left base and 1 of our flight school aircraft checked the traffic pattern and then quickly departed. My student and I pulled up to the hold short lines and angled the aircraft for a positive view of the left base and final leg for the active runway. I expected to readily find the small transport but he was nowhere in sight, so I told the student to expedite a takeoff. However, he radioed taking the active, then slowly taxied out onto the displaced threshold and aligned the aircraft with the centerline. As a last precaution, I looked out of the rear window of our aircraft and the small transport was only about 100 ft away. I knew it was too late to taxi clear so I made sure my student didn't move us. The small transport flew down to our level, over the grass, and then executed a go around back into the pattern. My thought is that because the small transport was beige with blue stripes, he must have blended in with the haze and already been on final. We could have avoided this situation had my student and I waited, if the small transport pilot had called final and had his landing light on.

Title: NMAC WITH LNDG ARR TFC. UNAUTH UNCOORD RWY ENTRY AT NON TWR ARPT.

Narrative: I WAS ON MY FIRST TRAINING FLT WITH A PARTICULAR STUDENT THAT I HADN'T FLOWN WITH BEFORE. I WAS GOING TO EVALUATE HIS READINESS FOR HIS PRIVATE PLT CHK RIDE. WE HAD COMPLETED THE BEFORE TKOF CHKLIST. WHILE GOING THROUGH THE RUNUP, WE HAD HEARD AN SMT PLT MAKE AN 8 MI OUT AND 4 MI OUT RADIO CALL, INBOUND FOR LNDG AND EVENTUALLY AN ABEAM-THE-FIELD CALL. THE LAST CALL WAS A L BASE AND 1 OF OUR FLT SCHOOL ACFT CHKED THE TFC PATTERN AND THEN QUICKLY DEPARTED. MY STUDENT AND I PULLED UP TO THE HOLD SHORT LINES AND ANGLED THE ACFT FOR A POSITIVE VIEW OF THE L BASE AND FINAL LEG FOR THE ACTIVE RWY. I EXPECTED TO READILY FIND THE SMT BUT HE WAS NOWHERE IN SIGHT, SO I TOLD THE STUDENT TO EXPEDITE A TKOF. HOWEVER, HE RADIOED TAKING THE ACTIVE, THEN SLOWLY TAXIED OUT ONTO THE DISPLACED THRESHOLD AND ALIGNED THE ACFT WITH THE CTRLINE. AS A LAST PRECAUTION, I LOOKED OUT OF THE REAR WINDOW OF OUR ACFT AND THE SMT WAS ONLY ABOUT 100 FT AWAY. I KNEW IT WAS TOO LATE TO TAXI CLR SO I MADE SURE MY STUDENT DIDN'T MOVE US. THE SMT FLEW DOWN TO OUR LEVEL, OVER THE GRASS, AND THEN EXECUTED A GAR BACK INTO THE PATTERN. MY THOUGHT IS THAT BECAUSE THE SMT WAS BEIGE WITH BLUE STRIPES, HE MUST HAVE BLENDED IN WITH THE HAZE AND ALREADY BEEN ON FINAL. WE COULD HAVE AVOIDED THIS SIT HAD MY STUDENT AND I WAITED, IF THE SMT PLT HAD CALLED FINAL AND HAD HIS LNDG LIGHT ON.
