Narrative:

On approach to wvl on VOR/DME approach I experienced a problem with the left landing gear. I missed the approach after reaching VFR conditions and climbed up requesting 5000' to VFR conditions where I knew the ice would come off. While at 5000' I entered the hold and attempted to fix the landing gear problem. The autoplt failed to hold altitude and heading while I pumped the landing gear down and I was so centered on the landing gear that I failed to notice the aircraft climbing and turning off course. When I realized what had happened I corrected the aircraft. I was unable to extend the landing gear and made a landing with the left gear up. There was minor damage and no one was hurt. The incident was reported to FAA and then classified a incident.

Title: PLT OF ATX SMT IS UNABLE TO GET LEFT MAIN LNDG GEAR DOWN DURING APCH INTO WVL AND ENTERS HOLDING PATTERN TO TROUBLESHOOT PROBLEM. DISTR WITH ACFT EQUIPMENT PROBLEM ALLOWS ACFT TO DEVIATE FROM TRACK AND ALT. PLT UNABLE TO FIX LNDG GEAR AND LANDED WITH LEFT MAIN UP.

Narrative: ON APCH TO WVL ON VOR/DME APCH I EXPERIENCED A PROBLEM WITH THE LEFT LNDG GEAR. I MISSED THE APCH AFTER REACHING VFR CONDITIONS AND CLIMBED UP REQUESTING 5000' TO VFR CONDITIONS WHERE I KNEW THE ICE WOULD COME OFF. WHILE AT 5000' I ENTERED THE HOLD AND ATTEMPTED TO FIX THE LNDG GEAR PROBLEM. THE AUTOPLT FAILED TO HOLD ALT AND HEADING WHILE I PUMPED THE LNDG GEAR DOWN AND I WAS SO CENTERED ON THE LNDG GEAR THAT I FAILED TO NOTICE THE ACFT CLIMBING AND TURNING OFF COURSE. WHEN I REALIZED WHAT HAD HAPPENED I CORRECTED THE ACFT. I WAS UNABLE TO EXTEND THE LNDG GEAR AND MADE A LNDG WITH THE LEFT GEAR UP. THERE WAS MINOR DAMAGE AND NO ONE WAS HURT. THE INCIDENT WAS REPORTED TO FAA AND THEN CLASSIFIED A INCIDENT.
