Narrative:
On may/sat/96, I was on a dual training flight in a cessna 172RG, in closed left traffic around runway 19L at rvs in tulsa, ok. On my second or third time around the pattern I had a near miss with a cessna 172. I was flying downwind abeam the numbers looking for my traffic. While observing my traffic, which was over the numbers on short final to land, I saw a cessna 172 pass directly 100 ft below me 90 degrees offset to my flight path on what appeared to be on base for runway 19L. I did not see him until after he passed below me and I don't believe he saw me until I had flown over him. No evasive action was taken. Our random difference in altitude was the only factor that prevented this collision. No advisory was issued by ATC leading up to or following the event. The pilot of the other plane informed ATC of the near miss with some excitement and I extended my downwind leg.

Title: ON THE DOWNWIND IN THE TFC PATTERN THE RPTR SEES A CESSNA 172 FLYING FROM R TO L AFTER PASSING 100 FT BENEATH HIM.
Narrative: ON MAY/SAT/96, I WAS ON A DUAL TRAINING FLT IN A CESSNA 172RG, IN CLOSED L TFC AROUND RWY 19L AT RVS IN TULSA, OK.

WHILE OBSERVING MY TFC, WHICH WAS OVER THE NUMBERS ON SHORT FINAL TO LAND, I SAW A CESSNA 172 PASS DIRECTLY 100 FT BELOW ME 90 DEGS OFFSET TO MY FLT PATH ON WHAT APPEARED TO BE ON BASE FOR RWY 19L. I DID NOT SEE HIM UNTIL AFTER HE PASSED BELOW ME AND I DON'T BELIEVE HE SAW ME UNTIL I HAD FLOWN OVER HIM. NO EVASIVE ACTION WAS TAKEN.
