Narrative:
I was practicing glide-in approachs at rainbow valley dirt strip runway 35, l-hand pattern. At that moment I was passing about 3500 ft, climbing to 4000 ft MSL for the third approach. All recommended position reports were made on unicom 122.90 MHZ. The other traffic did not report and was apparently not on this frequency, otherwise he would have known our position. Because of the sun's position, the other traffic was invisible for us until the moment of the near midair collision. I was head-on and slightly below the other aircraft. When the other traffic came in sight, I pushed the aircraft down and to the right as an evasive action. This incident happened because of a lack of communication, in this case, from the other aircraft on 122.90 MHZ.

Title: A BE33 BONANZA ALMOST COLLIDES HEAD ON WITH A PIPER TYPE ACFT WHILE IN A HIGH TFC PATTERN NEAR A RAINBOW VALLEY DIRT STRIP ARPT. BE33 CTAF RPTS ON 122 PT 90.
Narrative: I WAS PRACTICING GLIDE-IN APCHS AT RAINBOW VALLEY DIRT STRIP RWY 35, L-HAND PATTERN. AT THAT MOMENT I WAS PASSING ABOUT 3500 FT, CLBING TO 4000 FT MSL FOR THE THIRD APCH. ALL RECOMMENDED POS RPTS WERE MADE ON UNICOM 122.90 MHZ. THE OTHER TFC DID NOT RPT AND WAS APPARENTLY NOT ON THIS FREQ, OTHERWISE HE WOULD HAVE KNOWN OUR POS. BECAUSE OF THE SUN'S POS, THE OTHER TFC WAS INVISIBLE FOR US UNTIL THE MOMENT OF THE NMAC. I WAS HEAD-ON AND SLIGHTLY BELOW THE OTHER ACFT. WHEN THE OTHER TFC CAME IN SIGHT, I PUSHED THE ACFT DOWN AND TO THE R AS AN EVASIVE ACTION. THIS INCIDENT HAPPENED BECAUSE OF A LACK OF COM, IN THIS CASE, FROM THE OTHER ACFT ON 122.90 MHZ.
