Narrative:
Myself and a private pilot seeking a biannual flight review were practicing touch and go's at 06A. Glider operations were being conducted at the time and we were aware of this fact. First incident occurred when a glider turned final for the opposite runway while we were 'on the go' from a touch and go. We rotated and turned out as soon as possible as an aborted takeoff would not allow enough time to get off the runway. We continued the touch and go operations. As we flew a left hand pattern for runway 13, east of the runway, another glider operated west of the field. As we turned a 1/2 mi final for runway 13, the glider continued to operate to the west. However, as we continued on final, the glider stopped maneuvering and entered a tight right base, on a collision course with our aircraft. The glider was in sight at all times and the situation monitored so as not to create a dangerous situation. The glider pilot apparently saw us on final as he neared the extended centerline of runway 13. At this point he made a sharp 60 degree right turn to final and continued so as to land in the grass between the runway and the taxiway. We executed a go around. Lack of communication devices in the glider contributed to this incident. The procedures used by the gliders need to be understood by all using airports with mixed traffic. We were unsure of what action to take to avoid the glider, as his actions were totally unpredictable. Lesson learned: if someone is operating at an uncontrolled airport with no radio, then leave. If someone is operating a glider (or any different type of aircraft) without a radio then run!

Title: NMAC -- AN INSTRUCTOR CONDUCTING A FLT CHK HAS A NMAC WITH A GLIDER IN THE TFC PATTERN.
Narrative: MYSELF AND A PVT PLT SEEKING A BIANNUAL FLT REVIEW WERE PRACTICING TOUCH AND GO'S AT 06A. GLIDER OPS WERE BEING CONDUCTED AT THE TIME AND WE WERE AWARE OF THIS FACT. FIRST INCIDENT OCCURRED WHEN A GLIDER TURNED FINAL FOR THE OPPOSITE RWY WHILE WE WERE 'ON THE GO' FROM A TOUCH AND GO. WE ROTATED AND TURNED OUT AS SOON AS POSSIBLE AS AN ABORTED TKOF WOULD NOT ALLOW ENOUGH TIME TO GET OFF THE RWY. WE CONTINUED THE TOUCH AND GO OPS. AS WE FLEW A L HAND PATTERN FOR RWY 13, E OF THE RWY, ANOTHER GLIDER OPERATED W OF THE FIELD. AS WE TURNED A 1/2 MI FINAL FOR RWY 13, THE GLIDER CONTINUED TO OPERATE TO THE W. HOWEVER, AS WE CONTINUED ON FINAL, THE GLIDER STOPPED MANEUVERING AND ENTERED A TIGHT R BASE, ON A COLLISION COURSE WITH OUR ACFT. THE GLIDER WAS IN SIGHT AT ALL TIMES AND THE SIT MONITORED SO AS NOT TO CREATE A DANGEROUS SIT. THE GLIDER PLT APPARENTLY SAW US ON FINAL AS HE NEARED THE EXTENDED CTRLINE OF RWY 13. AT THIS POINT HE MADE A SHARP 60 DEG R TURN TO FINAL AND CONTINUED SO AS TO LAND IN THE GRASS BTWN THE RWY AND THE TXWY. WE EXECUTED A GAR. LACK OF COM DEVICES IN THE GLIDER CONTRIBUTED TO THIS INCIDENT. THE PROCS USED BY THE GLIDERS NEED TO BE UNDERSTOOD BY ALL USING ARPTS WITH MIXED TFC. WE WERE UNSURE OF WHAT ACTION TO TAKE TO AVOID THE GLIDER, AS HIS ACTIONS WERE TOTALLY UNPREDICTABLE. LESSON LEARNED: IF SOMEONE IS OPERATING AT AN UNCTLED ARPT WITH NO RADIO, THEN LEAVE. IF SOMEONE IS OPERATING A GLIDER (OR ANY DIFFERENT TYPE OF ACFT) WITHOUT A RADIO THEN RUN!
