BE36 PLT HAS ELECTRICAL PROB AND PENETRATES TKI AIRSPACE WITHOUT CLRNC WHILE TROUBLESHOOTING.

Narrative

MY ACFT HAD A VERY LONG IDLE TIME FROM STARTUP TO TKOF. IN ADDITION; THIS ACFT IS NOT GENERALLY FLOWN WITH GREAT REGULARITY AND HAD NOT BEEN FLOWN IN 5 DAYS. THE AMP METER WAS DISCHARGING (AS IT NORMALLY DOES AT LOW RPM). ONCE CLRED FOR TKOF BY ADS TWR; I ADDED FULL PWR AND PULLED UP ON THE GEAR HANDLE AFTER ROTATION. THE WHITE 'IN-TRANSIT' LIGHT WENT ON AND STAYED ON; AND I COULD NOT GET THE NORMAL CLBOUT SPD ON TKOF. I ASSUMED THAT THE GEAR WAS HALF-RETRACTED. ON TURN OUT TO THE E; ADS TWR ASKED ME IF MY XPONDER WAS 'ON.' I THEN NOTICED THAT MY SECOND RADIO; XPONDER AND AUTOPLT WERE NOT ILLUMINATED AND NOT OPERATING. MY GARMIN 430 WAS STILL OPERATING; AND I REPLIED TO THE TWR THAT I NEEDED TO STAY IN THE PATTERN TO LAND AND TROUBLESHOOT THE ELECTRICAL PROBS ON THE GND. THE TWR COULD NOT HEAR MY XMISSIONS. I CLBED TO 2500 FT MSL AND NOTICED THAT THE AMP METER WAS STILL DISCHARGING. I HEADED NE TOWARD TKI. I DISENGAGED THE CIRCUIT BREAKER AND ATTEMPTED TO HAND CRANK THE GEAR DOWN; BUT WAS UNABLE TO GET 3 GREEN LIGHTS. DURING THIS TIME; I ENTERED TKI'S CLASS D AIRSPACE. I THEN HEADED N OF TKI TO CONTINUE TO WORK ON THE GEAR PROB WITH THE HOPES OF LNDG AT TKI. I ENGAGED THE CIRCUIT BREAKER AND 3 GREEN LIGHTS APPEARED. I CONTINUED TO TRY TO CONTACT TKI; BUT COULD NOT HEAR THE ATIS; NOR ESTABLISH CONTACT WITH THE TWR. THE SECOND RADIO CAME BACK ON LINE; AS WELL AS THE XPONDER AND AUTOPLT. I MISTAKENLY SQUAWKED 7700 TO INDICATE A COM FAILURE (INSTEAD OF 7600). WITHIN A MIN; I WAS ABLE TO CONTACT THE TKI TWR TO INDICATE THAT I HAD HAD ELECTRICAL PROBS BUT THAT EVERYTHING NOW APPEARED IN ORDER. I THEN ADVISED THE TWR THAT I WAS GOING TO SQUAWK 1200 AND CONTACT APCH ON 124.25 TO THE APCH INTO ADS. WHILE THE RADIOS WORKED FINE; BOTH TKI AND APCH INDICATED MY XPONDER WAS NOT RPTING MY ALT. I LANDED AT ADS WITHOUT ANY FURTHER TROUBLE. AFTER LNDG; I DISCUSSED THE SITUATION WITH THE ACFT OWNER AND MY INSTRUCTOR IN THE ACFT. WE DISCUSSED THE NEED TO TURN OFF THE SECOND RADIO AND XPONDER; AND TO IDLE AT A HIGHER THAN NORMAL RPM WHEN FACED WITH A LONG IDLE TIME. MY ANXIETY AT WHAT I PERCEIVED TO BE A DEVELOPING EMER SITUATION CAUSED ME TO LOSE FOCUS AND FLY INTO TKI AIRSPACE. I AM GOING TO REVIEW ALL EMER PROCS FOR THIS ACFT. FINALLY; I HAVE REVIEWED THE XPONDER CODES TO AVOID MAKING THAT MISTAKE IN THE FUTURE.
