A BEECH G35 RETURNED TO THE FIELD DUE TO ELECTRICAL SYS FAILURE.

Narrative

PURCHASED THE BONANZA IN BRUNSWICK; GA; ON MAY/XA/97. UPON STARTUP; FOUND THAT THE BATTERY WAS DEAD. MAINT STAFF BROUGHT OUT A GPU AND JUMPED THE PLANE. ALL SEEMED FINE; SO I RESUMED THE FLT. ABOUT 5 MI N OF PORT OF COLUMBUS; I DETECTED AN ACRID SMELL IN THE COCKPIT AND NOTICED THAT THE AMMETER SHOWED BATTERY HAD FAILED TO HOLD A CHARGE. I SWITCHED OFF THE GENERATOR; TURNED OFF NON ESSENTIAL PWR; CLOSED THE AIR VENTS AND CALLED CTL AND REQUESTED PERMISSION TO LAND IMMEDIATELY. CTL CLRED ME FOR THE LNDG. MY PARTNER AND I BEGAN SHUTTING DOWN SYS AND CONFIGURING FOR THE LNDG. LANDED THE PLANE FINE; NOTIFIED THE LINE CREW OF THE PROB AND CALLED THE TWR FROM THE PHONE IN THE FBO TO LET THEM KNOW WE WERE OK AND THAT I WAS HAVING THE PLANE'S ELECTRICAL SYS CHKED. ON INITIAL GLANCE; THE MAINT CREW ADVISED THAT WE LEAVE THE PLANE FOR A MORE THOROUGH CHKOUT. MY PARTNER AND I RENTED A CAR AND RETURNED HOME TO DAYTON. MAINT ADVISED ME THAT THEY HAD FOUND SIGNIFICANT PROBS WITH THE ELECTRICAL SYS AND RECOMMENDED THAT I TAKE THE PLANE TO XYZ; THE LCL BEECHCRAFT SVC CTR FOR A MAINT CHK. XYZ IS LOCATED AT ZZZ ARPT. IN THE MEANTIME; THEY AGAIN TETHERED THE WIRING AND CHARGED THE BATTERY. I EXPERIENCED SIGNIFICANT TROUBLE GETTING A GOOD COMS CHANNEL TO CLRNC. I COULD RECEIVE; HOWEVER; CLRNC HAD TROUBLE UNDERSTANDING MY XMISSION DUE TO STATIC AND INTERMITTENT LOSS OF SIGNAL. AFTER RECEIVING MY CLRNC; I TAXIED TO RWY 10R AS ASSIGNED AND PERFORMED A SYS CHK WITH THE RUNUP. ALL SYS CHKED. I SWITCHED TO TWR TO ADVISE THAT I WAS READY TO DEPART AND AGAIN EXPERIENCED TROUBLE XMITTING A CLR SIGNAL. AFTER DEP; I TOOK THE ASSIGNED RWY HDG AND STARTED MY ASSIGNED CLB TO 4500 FT. THE TWR CALLED TO ADVISE A COURSE CHANGE TO 180 DEGS; HOWEVER BOTH XMIT AND RECEIVE SIGNALS FAILED. I SWITCHED BTWN BOTH RADIO SETS IN AN ATTEMPT TO GET A CLR SIGNAL; THEN NOTICED THAT THE BATTERY HAD AGAIN BEGUN A SIGNIFICANT DISCHARGE. I PICKED UP A CALL FROM DEP DIRECTING ME TO TURN IMMEDIATELY TO 180 DEGS. I RESPONDED WITH THE COURSE CHANGE AND REQUESTED A RETURN TO THE FIELD AS I WAS EXPERIENCING RADIO PROBS. DEP GRANTED THE REQUEST CLRING ME FOR RWY 10R AND ASKED THAT I IDENT IF I COPIED. I IDENTED. DEP AGAIN CALLED STATING THAT SHE WAS NOT RECEIVING MY MODE C AND ASKED FOR MY ALT. I RESPONDED WITH 'LEAVING 3000 FT FOR 4500 FT.' DEP RESPONDED STATING THAT SHE WAS NOT ABLE TO UNDERSTAND MY XMISSION AND ASKED IF I WAS HAVING PROBS. I RESPONDED THAT I WAS HAVING RADIO PROBS. DEP RESPONDED STATING THAT SHE WAS NOT ABLE TO UNDERSTAND MY XMISSION AND ASKED THAT I IDENT IF THIS WERE AN EMER. I SWITCHED RADIOS REPEATEDLY AND RESPONDED STATING THAT THIS WAS NOT AN EMER; THAT I WAS HAVING RADIO PROBS. MY AMMETER CONTINUED TO SHOW A DISCHARGE. DEP CALLED STATING THAT SHE HAD RECEIVED AN IDENT AND HAD DISPATCHED EQUIP TO THE FIELD. I WAS CLRED FOR RWY 10R. AFTER SWITCHING FROM RADIO TO RADIO; I WAS ABLE TO XMIT THAT THIS WAS NOT AN EMER; THAT I WAS EXPERIENCING RADIO AND ELECTRICAL PROBS; THAT I UNDERSTOOD I WAS CLRED FOR RWY 10R AND PLANNED TO RETURN TO THE FBO FOR MAINT. SHE RESPONDED STATING THAT SHE HAD RECEIVED MY XMISSION; UNDERSTOOD THAT THIS WAS NOT AN EMER; BUT THAT EQUIP HAD ALREADY BEEN DISPATCHED. I WAS CLRED TO FBO. SINCE THE INCIDENT; FBO HAS ASCERTAINED THAT THE BONANZA'S GENERATOR FAILED AND THAT THE WORN WIRING CONTINUED TO BE AN ISSUE. CURRENTLY; THEY ARE REPLACING THE GENERATOR AND MAKING REPAIRS TO THE WIRING. MY INTENTION IS TO GET A FERRY PERMIT AND TRANSPORT THE PLANE TO ABC FOR AN ANNUAL AND STRUCTURAL INSPECTION. I AM ALSO TAKING ISSUE WITH THE FBO THAT PERFORMED THE PRE- BUY INSPECTION.
