Small aircraft X reported 10 south of salem airport for landing. He was issued instructions to enter right downwind for runway 16 and to report entering downwind. A short time later (2 mins or so) small aircraft X requested a straight-in to runway 16. The controller verified the position of small aircraft X as south of the airport and pointed out that small aircraft X position was better for the right downwind entry. Small aircraft X finally agreed. Small aircraft X was reissued enter and report right downwind runway 16. Small aircraft X then (approximately 2 mins later) reported entering downwind. Small aircraft X was not observed and was asked his position if right downwind. Small aircraft X stated he was on left downwind and was observed there. During this time there had been one small aircraft Y who had departed east. Neither the small aircraft X nor the small aircraft Y had been issued traffic. They would have been clear of each other if the small aircraft X had entered right downwind as instructed.

Title: ACFT WAS INSTRUCTED TO ENTER A RIGHT DOWNWIND LEG AND ACFT ENTERED THE TRAFFIC PATTERN ON A LEFT DOWNWIND.
Narrative: SMA X RPTED 10 S OF SALEM ARPT FOR LNDG. HE WAS ISSUED INSTRUCTIONS TO ENTER R DOWNWIND FOR RWY 16 AND TO RPT ENTERING DOWNWIND. A SHORT TIME LATER (2 MINS OR SO) SMA X REQUESTED A STRAIGHT-IN TO RWY 16. THE CTLR VERIFIED THE POS OF SMA X AS S OF THE ARPT AND POINTED OUT THAT SMA X POS WAS BETTER FOR THE R DOWNWIND ENTRY. SMA X FINALLY AGREED. SMA X WAS REISSUED ENTER AND RPT R DOWNWIND RWY 16. SMA X THEN (APPROX 2 MINS LATER) RPTED ENTERING DOWNWIND. SMA X WAS NOT OBSERVED AND WAS ASKED HIS POS IF R DOWNWIND. SMA X STATED HE WAS ON L DOWNWIND AND WAS OBSERVED THERE. DURING THIS TIME THERE HAD BEEN ONE SMA Y WHO HAD DEPARTED E. NEITHER THE SMA X NOR THE SMA Y HAD BEEN ISSUED TFC. THEY WOULD HAVE BEEN CLR OF EACH OTHER IF THE SMA X HAD ENTERED R DOWNWIND AS INSTRUCTED.
