Narrative:
I was maintaining a visual scan while attempting to contact ZOA for VFR advisories while on a VFR flight from rno to woodland watts, ca. I became aware of the small aircraft and at the same instant I passed over the top of him. We were at the same approximately altitude and on the same heading, +/-10 degrees. I believe the small aircraft was partially camouflaged by the mountainous terrain. In any case, there was no silhouette against the sky of his airplane to assist visual contact. There was no time to react or change altitude or flight paths. Corrective action: increased scan. Incident was reported to sac TRACON by second aircraft. Callback conversation with reporter revealed the following: reporter had been terminated by rno center and was in process of contacting ZOA at time of sighting. As he began his descent he was handed off to sac and second aircraft came on frequency with statement, '(identification #) you'll be hearing from me.' supervisor gave reporter phone # and asked to call after landing. Reporter gave supervisor the basic information about the incident and was told it would be sent on to safety officer. To date reporter has heard nothing.

Title: NMAC BETWEEN 2 GA-SMA'S. NEITHER SAW THE OTHER UNTIL THEY WERE WITHIN SECONDS OF MISSING EACH OTHER. NO TIME FOR EVASIVE ACTION.
Narrative: I WAS MAINTAINING A VISUAL SCAN WHILE ATTEMPTING TO CONTACT ZOA FOR VFR ADVISORIES WHILE ON A VFR FLT FROM RNO TO WOODLAND WATTS, CA. I BECAME AWARE OF THE SMA AND AT THE SAME INSTANT I PASSED OVER THE TOP OF HIM. WE WERE AT THE SAME APPROX ALT AND ON THE SAME HDG, +/-10 DEGS. I BELIEVE THE SMA WAS PARTIALLY CAMOUFLAGED BY THE MOUNTAINOUS TERRAIN. IN ANY CASE, THERE WAS NO SILHOUETTE AGAINST THE SKY OF HIS AIRPLANE TO ASSIST VISUAL CONTACT. THERE WAS NO TIME TO REACT OR CHANGE ALT OR FLT PATHS. CORRECTIVE ACTION: INCREASED SCAN. INCIDENT WAS RPTED TO SAC TRACON BY SECOND ACFT. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING: REPORTER HAD BEEN TERMINATED BY RNO CENTER AND WAS IN PROCESS OF CONTACTING ZOA AT TIME OF SIGHTING. AS HE BEGAN HIS DSCNT HE WAS HANDED OFF TO SAC AND SECOND ACFT CAME ON FREQ WITH STATEMENT, '(ID #) YOU'LL BE HEARING FROM ME.' SUPVR GAVE RPTR PHONE # AND ASKED TO CALL AFTER LNDG. RPTR GAVE SUPVR THE BASIC INFO ABOUT THE INCIDENT AND WAS TOLD IT WOULD BE SENT ON TO SAFETY OFFICER. TO DATE RPTR HAS HEARD NOTHING.
