Narrative:

On a clear day at an airport with an operating control tower, I was cleared to land on runway 5. I mistakenly identified runway 23 as runway 5 and landed downwind on the active runway. There was no conflict with other aircraft. Callback conversation with reporter revealed the following: tower had asked where reporter was when reporter reported entering downwind. Tower then said, 'oh, there you are,' and cleared him to land. Tower obviously was looking at a different aircraft and had no reason to suspect the reporter was not on downwind as he said.

Narrative: ON A CLR DAY AT AN ARPT WITH AN OPERATING CTL TWR, I WAS CLRED TO LAND ON RWY 5. I MISTAKENLY IDENTIFIED RWY 23 AS RWY 5 AND LANDED DOWNWIND ON THE ACTIVE RWY. THERE WAS NO CONFLICT WITH OTHER ACFT. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING: TWR HAD ASKED WHERE RPTR WAS WHEN RPTR RPTED ENTERING DOWNWIND. TWR THEN SAID, 'OH, THERE YOU ARE,' AND CLRED HIM TO LAND. TWR OBVIOUSLY WAS LOOKING AT A DIFFERENT ACFT AND HAD NO REASON TO SUSPECT THE RPTR WAS NOT ON DOWNWIND AS HE SAID.
