Narrative:

I was flying a C206 and conducting landing practice and traffic pattern work at the orcas island; wa; east sound airport with another pilot. During a go around procedure on runway 16; I made the go around call on the CTAF and began a climb. While still climbing to traffic pattern altitude and approximately 5 seconds after leveling the wings on a crosswind leg at approximately 700 ft when the PNF in the aircraft observed an aircraft entering the traffic pattern; straight-in from an extended downwind leg at the same altitude. This aircraft had made no radio calls on the CTAF prior to the incident. The PNF called out; 'airplane; go down!' I immediately pushed the yoke forward and observed a C172 pass directly over us at a distance of approximately 10 ft. After the C172 passed over us; a female pilot made a radio call on the CTAF saying 'the aircraft that just passed under us; I thought you had landed.' this was the first time that the aircraft made any radio call at all. She had entered the traffic pattern straight-in from an extended downwind leg at 300 ft below pattern altitude without making any radio calls. The first TA call she made was when she entered a base leg for landing after the incident. We were shaken up to the point that we both decided to depart the area; go home and quit flying for the day.

Title: WHILE PRACTICING TOUCH-AND-GOES AT AN UNCTLED ARPT; C206 HAS NEAR MISS WITH C172 WHOSE PLT HAD MADE NO CTAF RPTS.

Narrative: I WAS FLYING A C206 AND CONDUCTING LNDG PRACTICE AND TFC PATTERN WORK AT THE ORCAS ISLAND; WA; EAST SOUND ARPT WITH ANOTHER PLT. DURING A GAR PROC ON RWY 16; I MADE THE GAR CALL ON THE CTAF AND BEGAN A CLB. WHILE STILL CLBING TO TFC PATTERN ALT AND APPROX 5 SECONDS AFTER LEVELING THE WINGS ON A XWIND LEG AT APPROX 700 FT WHEN THE PNF IN THE ACFT OBSERVED AN ACFT ENTERING THE TFC PATTERN; STRAIGHT-IN FROM AN EXTENDED DOWNWIND LEG AT THE SAME ALT. THIS ACFT HAD MADE NO RADIO CALLS ON THE CTAF PRIOR TO THE INCIDENT. THE PNF CALLED OUT; 'AIRPLANE; GO DOWN!' I IMMEDIATELY PUSHED THE YOKE FORWARD AND OBSERVED A C172 PASS DIRECTLY OVER US AT A DISTANCE OF APPROX 10 FT. AFTER THE C172 PASSED OVER US; A FEMALE PLT MADE A RADIO CALL ON THE CTAF SAYING 'THE ACFT THAT JUST PASSED UNDER US; I THOUGHT YOU HAD LANDED.' THIS WAS THE FIRST TIME THAT THE ACFT MADE ANY RADIO CALL AT ALL. SHE HAD ENTERED THE TFC PATTERN STRAIGHT-IN FROM AN EXTENDED DOWNWIND LEG AT 300 FT BELOW PATTERN ALT WITHOUT MAKING ANY RADIO CALLS. THE FIRST TA CALL SHE MADE WAS WHEN SHE ENTERED A BASE LEG FOR LNDG AFTER THE INCIDENT. WE WERE SHAKEN UP TO THE POINT THAT WE BOTH DECIDED TO DEPART THE AREA; GO HOME AND QUIT FLYING FOR THE DAY.
