Narrative:

While approaching midway airport from the southeast at 1900 ft, and requesting landing instructions, I was told I was #1 to land, runway 31C. Flaps and wheels down, I was notified that traffic was at my 6 O'clock position and to proceed. I was then told to increase speed, that traffic behind me was faster (air carrier). I suggested to tower I make a right 36O degree turn to make room for faster traffic. Tower concurred and asked that I make 360 degree turn. Upon completion of turn, I was notified that I was clear to land. I tuned in localizer (109.9), centered needle, landed. Note: field covered in 10-15 inches of snow, except runways. Having departed runway 31L, I idented 2 runways -- as noted. Landed without incident. Upon slowing, was instructed to do a 180 degree turn and 'hold short runway 31C.' I informed tower I was on runway 31C, and they said 'you are on runway 31R, hold short runway 31C.' I was stunned! I know there is no excuse -- but from my turnaround position I only idented 2 runways (believing I was on runway 31C with centered localizer needle).

Original NASA ASRS Text

Title: C310 PLT LANDED ON THE WRONG RWY AT MDW.

Narrative: WHILE APCHING MIDWAY ARPT FROM THE SE AT 1900 FT, AND REQUESTING LNDG INSTRUCTIONS, I WAS TOLD I WAS #1 TO LAND, RWY 31C. FLAPS AND WHEELS DOWN, I WAS NOTIFIED THAT TFC WAS AT MY 6 O'CLOCK POS AND TO PROCEED. I WAS THEN TOLD TO INCREASE SPD, THAT TFC BEHIND ME WAS FASTER (ACR). I SUGGESTED TO TWR I MAKE A R 36O DEG TURN TO MAKE ROOM FOR FASTER TFC. TWR CONCURRED AND ASKED THAT I MAKE 360 DEG TURN. UPON COMPLETION OF TURN, I WAS NOTIFIED THAT I WAS CLR TO LAND. I TUNED IN LOC (109.9), CTRED NEEDLE, LANDED. NOTE: FIELD COVERED IN 10-15 INCHES OF SNOW, EXCEPT RWYS. HAVING DEPARTED RWY 31L, I IDENTED 2 RWYS -- AS NOTED. LANDED WITHOUT INCIDENT. UPON SLOWING, WAS INSTRUCTED TO DO A 180 DEG TURN AND 'HOLD SHORT RWY 31C.' I INFORMED TWR I WAS ON RWY 31C, AND THEY SAID 'YOU ARE ON RWY 31R, HOLD SHORT RWY 31C.' I WAS STUNNED! I KNOW THERE IS NO EXCUSE -- BUT FROM MY TURNAROUND POS I ONLY IDENTED 2 RWYS (BELIEVING I WAS ON RWY 31C WITH CTRED LOC NEEDLE).
