Narrative:

Small aircraft X, a cessna 172, was in right closed traffic to runway 24. Atx Y, a BA31, was on final for runway 24. X made a 360 degree turn on downwind for spacing. X reported back on downwind and was instructed to follow the BA31 on 2 mi final and told to advise when X had the traffic in sight. X said 'negative.' then Y said he had traffic coming at him. I asked X if she was still on the downwind. She said affirmative. Y was told the cessna will follow him and Y said the cessna was not on downwind, but opposite direction on the final. I believe when X came out of the 360 degree turn back to downwind was too close to the final the runway. X was a student pilot in tough-and-go pattern. Supplemental information from acn 266636: I am a student pilot and was on my second unsupervised solo. I was on my downwind leg for runway 24. The tower told me to do a left 360 degree turn, which I did. I was on an extended downwind, I didn't have a ground reference to base my distance on. I noticed I was drifting and corrected, but only to find that I drifted anyhow. I looked up and saw another aircraft and heard him call the tower. At this time I proceeded to correct the situation. I feel that this was not that hazardous of a situation because I had the time and room to correct the situation.

Title: SMA X HAD NMAC WITH ATX Y IN ATA. EVASIVE ACTION TURN. SEE AND AVOID CONCEPT.

Narrative: SMA X, A CESSNA 172, WAS IN R CLOSED TFC TO RWY 24. ATX Y, A BA31, WAS ON FINAL FOR RWY 24. X MADE A 360 DEG TURN ON DOWNWIND FOR SPACING. X RPTED BACK ON DOWNWIND AND WAS INSTRUCTED TO FOLLOW THE BA31 ON 2 MI FINAL AND TOLD TO ADVISE WHEN X HAD THE TFC IN SIGHT. X SAID 'NEGATIVE.' THEN Y SAID HE HAD TFC COMING AT HIM. I ASKED X IF SHE WAS STILL ON THE DOWNWIND. SHE SAID AFFIRMATIVE. Y WAS TOLD THE CESSNA WILL FOLLOW HIM AND Y SAID THE CESSNA WAS NOT ON DOWNWIND, BUT OPPOSITE DIRECTION ON THE FINAL. I BELIEVE WHEN X CAME OUT OF THE 360 DEG TURN BACK TO DOWNWIND WAS TOO CLOSE TO THE FINAL THE RWY. X WAS A STUDENT PLT IN TOUGH-AND-GO PATTERN. SUPPLEMENTAL INFO FROM ACN 266636: I AM A STUDENT PLT AND WAS ON MY SECOND UNSUPERVISED SOLO. I WAS ON MY DOWNWIND LEG FOR RWY 24. THE TWR TOLD ME TO DO A L 360 DEG TURN, WHICH I DID. I WAS ON AN EXTENDED DOWNWIND, I DIDN'T HAVE A GND REF TO BASE MY DISTANCE ON. I NOTICED I WAS DRIFTING AND CORRECTED, BUT ONLY TO FIND THAT I DRIFTED ANYHOW. I LOOKED UP AND SAW ANOTHER ACFT AND HEARD HIM CALL THE TWR. AT THIS TIME I PROCEEDED TO CORRECT THE SIT. I FEEL THAT THIS WAS NOT THAT HAZARDOUS OF A SIT BECAUSE I HAD THE TIME AND ROOM TO CORRECT THE SIT.
