Narrative:

In small aircraft X using unicom in traffic making touch and go lndgs with student. While turning base to final, small aircraft Y taxied onto runway. Continued approach, assuming aircraft would depart quickly. Lowered 40 degree flap for slower approach and to avoid wake turbulence by landing on first 100' of runway 17. Aircraft on ground continued to hold in place until such time I took flight control of aircraft from student initiating go around and small aircraft X began takeoff roll apparently using short field techniques. As he began climbing out, near miss occurred requiring evasive action to left side of field. This placed aircraft in a potentially dangerous situation and at an extremely low altitude, high bank, low speed, flaps down 20 degree position. Causes: non-utilization of unicom, not clearing final at uncontrolled airfield on other aircraft's part, and failure to initiate early go around on my part.

Original NASA ASRS Text

Title: CLOSE PROX GA-SMA DOING TOUCH AND GO TRAINING AND GA-SMA ON TKOF ROLL.

Narrative: IN SMA X USING UNICOM IN TFC MAKING TOUCH AND GO LNDGS WITH STUDENT. WHILE TURNING BASE TO FINAL, SMA Y TAXIED ONTO RWY. CONTINUED APCH, ASSUMING ACFT WOULD DEPART QUICKLY. LOWERED 40 DEG FLAP FOR SLOWER APCH AND TO AVOID WAKE TURB BY LNDG ON FIRST 100' OF RWY 17. ACFT ON GND CONTINUED TO HOLD IN PLACE UNTIL SUCH TIME I TOOK FLT CTL OF ACFT FROM STUDENT INITIATING GO AROUND AND SMA X BEGAN TKOF ROLL APPARENTLY USING SHORT FIELD TECHNIQUES. AS HE BEGAN CLBING OUT, NEAR MISS OCCURRED REQUIRING EVASIVE ACTION TO LEFT SIDE OF FIELD. THIS PLACED ACFT IN A POTENTIALLY DANGEROUS SITUATION AND AT AN EXTREMELY LOW ALT, HIGH BANK, LOW SPD, FLAPS DOWN 20 DEG POS. CAUSES: NON-UTILIZATION OF UNICOM, NOT CLRING FINAL AT UNCTLED AIRFIELD ON OTHER ACFT'S PART, AND FAILURE TO INITIATE EARLY GO AROUND ON MY PART.
