Narrative:

I was plting an small aircraft into lkf, pattern procedures, landing technique and communication skills were to be polished. 10 mi out ATIS gave me runway 27 and 36L as active runways. I noted this on my kneeboard along with winds, altimeter, ATC...switching to lkf tower, I was cleared for 'touch and goes' on runway 27, along with about 3 other trainers. Instructions were to report base leg. As I reached base leg for runway 27, tower instructed me to switch to runway 36R, cleared to land. A 90 degree left turn was required to place myself on a right base to runway 36R. During this turn I need to lower my airspeed. Throttle was pulled back carburetor heat applied, and flaps attempted to lower. Flaps did not respond. A bit unnerved, I reached over to twist the fuse cap and regain electrical contact. This action did not give complete results and was abandoned. Final approach leg was coming up quickly, and I was now uncertain as to which runway I was cleared to land. A quick glance at my kneeboard notes showed runway 36L as active (10 min old ATIS notes). I lined up on runway 36L and called tower to advise landing full stop due to flap problems. At this time I noticed a low wing twing propeller to my left and behind my wing. This would be a left base for runway 36L. It seemed odd that spacing was that close for a 'twin' behind me. At this time landing in an unusual confign (no flaps) required my full attention. After landing tower advised me I had been cleared for runway 36A and had caused the 'twin' to go around. I was also asked to call the tower upon shutting down. During the telephone conversation the confusion of a low time pilot, given a rapid change of clearance, while trying to sort out cockpit problems, indicing uncertainty and hearback was discussed. I am grateful the pilot of the 'low wing twin' was vigilant. His timely and skillful go around avoided any further problems.

Title: GA SMA WRONG RWY APCH LNDG CAUSES GA LTT GO AROUND.

Narrative: I WAS PLTING AN SMA INTO LKF, PATTERN PROCS, LNDG TECHNIQUE AND COM SKILLS WERE TO BE POLISHED. 10 MI OUT ATIS GAVE ME RWY 27 AND 36L AS ACTIVE RWYS. I NOTED THIS ON MY KNEEBOARD ALONG WITH WINDS, ALTIMETER, ATC...SWITCHING TO LKF TWR, I WAS CLRED FOR 'TOUCH AND GOES' ON RWY 27, ALONG WITH ABOUT 3 OTHER TRAINERS. INSTRUCTIONS WERE TO RPT BASE LEG. AS I REACHED BASE LEG FOR RWY 27, TWR INSTRUCTED ME TO SWITCH TO RWY 36R, CLRED TO LAND. A 90 DEG LEFT TURN WAS REQUIRED TO PLACE MYSELF ON A RIGHT BASE TO RWY 36R. DURING THIS TURN I NEED TO LOWER MY AIRSPD. THROTTLE WAS PULLED BACK CARB HEAT APPLIED, AND FLAPS ATTEMPTED TO LOWER. FLAPS DID NOT RESPOND. A BIT UNNERVED, I REACHED OVER TO TWIST THE FUSE CAP AND REGAIN ELECTRICAL CONTACT. THIS ACTION DID NOT GIVE COMPLETE RESULTS AND WAS ABANDONED. FINAL APCH LEG WAS COMING UP QUICKLY, AND I WAS NOW UNCERTAIN AS TO WHICH RWY I WAS CLRED TO LAND. A QUICK GLANCE AT MY KNEEBOARD NOTES SHOWED RWY 36L AS ACTIVE (10 MIN OLD ATIS NOTES). I LINED UP ON RWY 36L AND CALLED TWR TO ADVISE LNDG FULL STOP DUE TO FLAP PROBS. AT THIS TIME I NOTICED A LOW WING TWING PROP TO MY LEFT AND BEHIND MY WING. THIS WOULD BE A LEFT BASE FOR RWY 36L. IT SEEMED ODD THAT SPACING WAS THAT CLOSE FOR A 'TWIN' BEHIND ME. AT THIS TIME LNDG IN AN UNUSUAL CONFIGN (NO FLAPS) REQUIRED MY FULL ATTN. AFTER LNDG TWR ADVISED ME I HAD BEEN CLRED FOR RWY 36A AND HAD CAUSED THE 'TWIN' TO GO AROUND. I WAS ALSO ASKED TO CALL THE TWR UPON SHUTTING DOWN. DURING THE TELEPHONE CONVERSATION THE CONFUSION OF A LOW TIME PLT, GIVEN A RAPID CHANGE OF CLRNC, WHILE TRYING TO SORT OUT COCKPIT PROBS, INDICING UNCERTAINTY AND HEARBACK WAS DISCUSSED. I AM GRATEFUL THE PLT OF THE 'LOW WING TWIN' WAS VIGILANT. HIS TIMELY AND SKILLFUL GO AROUND AVOIDED ANY FURTHER PROBS.
