Narrative:
I was on my second touch-and-go at Q99 turning downwind when a bonanza seemingly appeared out of nowhere on a 45 degree entry for the right downwind runway 32. My instructor took the controls and made a diving left turn. We rolled back to the right and re-entered the traffic pattern. We were in a head on collision at a distance of approximately 300 ft or less. The bonanza made no radio calls until after our evasive maneuver, acknowledging that he had us in sight and would be following us. He continued to fly a modified pattern off of our left wingtip, finally sequencing himself after I'd turned base following 2 other aircraft. In the postflt briefing, my instructor explained that he made a left evasive turn because it was the best way to maintain a visual on the other aircraft and not turn our belly to him. Also, my instructor anticipated that the other pilot's intention was to turn left and join the downwind leg.

Title: CH7A STUDENT AND INSTRUCTOR, WITH A BE35 HAD AN NMAC AT AN UNCTLED ARPT AFTER THE BE35 PLT DID NOT ANNOUNCE HIS ENTRY INTO THE ARPT TFC PATTERN.
Narrative: I WAS ON MY SECOND TOUCH-AND-GO AT Q99 TURNING DOWNWIND WHEN A BONANZA SEEMINGLY APPEARED OUT OF NOWHERE ON A 45 DEG ENTRY FOR THE R DOWNWIND RWY 32. MY INSTRUCTOR TOOK THE CTLS AND MADE A DIVING L TURN. WE ROLLED BACK TO THE R AND RE-ENTERED THE TFC PATTERN. WE WERE IN A HEAD ON COLLISION AT A DISTANCE OF APPROX 300 FT OR LESS. THE BONANZA MADE NO RADIO CALLS UNTIL AFTER OUR EVASIVE MANEUVER, ACKNOWLEDGING THAT HE HAD US IN SIGHT AND WOULD BE FOLLOWING US. HE CONTINUED TO FLY A MODIFIED PATTERN OFF OF OUR L WINGTIP, FINALLY SEQUENCING HIMSELF AFTER I'D TURNED BASE FOLLOWING 2 OTHER ACFT. IN THE POSTFLT BRIEFING, MY INSTRUCTOR EXPLAINED THAT HE MADE A L EVASIVE TURN BECAUSE IT WAS THE BEST WAY TO MAINTAIN A VISUAL ON THE OTHER ACFT AND NOT TURN OUR BELLY TO HIM. ALSO, MY INSTRUCTOR ANTICIPATED THAT THE OTHER PLT'S INTENTION WAS TO TURN L AND JOIN THE DOWNWIND LEG.
