Narrative:
I received my instrument rating in jun of 91. I have tried to maintain proficiency by flying with safety pilot or in instrument conditions at least 2-4 hours per month. I planned IFR flight to luk knowing cold front was approaching. However, forecasts called for light rain and ceilings of 3500 ft. I planned to file to calif intersection IFR and then proceed to cvg VFR on composite flight plan. En route I updated forecasts and WX through FSS and conditions were worsening. Also, my mode C quit working en route so I had to modify my flight plan to IFR approach lunken. At york VOR, I encountered reduced visibility which gradually worsened into 'hard' IFR conditions. I was issued vectors for luk 20L approach. Then my directional gyroscope began to 'hang up.' this made control difficult and coupled with my nervousness made the approach difficult to execute. I broke out at about 1000 ft AGL. Being in the clear, I got distracted and let my course wander coming close to the 20R approach course. Landing was uneventful. Remedy: practice, practice, practice.

Title: SMA PLT IFR HAS MODE C FAIL, THEN DIRECTIONAL GYROSCOPE HANGS UP. DRIFT TO APCH COURSE FOR PARALLEL RWY.
Narrative: I RECEIVED MY INST RATING IN JUN OF 91. I HAVE TRIED TO MAINTAIN PROFICIENCY BY FLYING WITH SAFETY PLT OR IN INST CONDITIONS AT LEAST 2-4 HRS PER MONTH. I PLANNED IFR FLT TO LUK KNOWING COLD FRONT WAS APCHING. HOWEVER, FORECASTS CALLED FOR LIGHT RAIN AND CEILINGS OF 3500 FT. I PLANNED TO FILE TO CALIF INTXN IFR AND THEN PROCEED TO CVG VFR ON COMPOSITE FLT PLAN. ENRTE I UPDATED FORECASTS AND WX THROUGH FSS AND CONDITIONS WERE WORSENING. ALSO, MY MODE C QUIT WORKING ENRTE SO I HAD TO MODIFY MY FLT PLAN TO IFR APCH LUNKEN. AT YORK VOR, I ENCOUNTERED REDUCED VISIBILITY WHICH GRADUALLY WORSENED INTO 'HARD' IFR CONDITIONS. I WAS ISSUED VECTORS FOR LUK 20L APCH. THEN MY DIRECTIONAL GYROSCOPE BEGAN TO 'HANG UP.' THIS MADE CTL DIFFICULT AND COUPLED WITH MY NERVOUSNESS MADE THE APCH DIFFICULT TO EXECUTE. I BROKE OUT AT ABOUT 1000 FT AGL. BEING IN THE CLR, I GOT DISTRACTED AND LET MY COURSE WANDER COMING CLOSE TO THE 20R APCH COURSE. LNDG WAS UNEVENTFUL. REMEDY: PRACTICE, PRACTICE, PRACTICE.
