I fly skydivers for X. On the date specified half way through flight I experienced a partial electrical failure. I could hear ZJX calling my aircraft but was unable to transmit. After several attempts ZJX asked another aircraft to call me on unicom. I switched to unicom, could hear the aircraft but was unable to transmit. The company has a LOA with the FAA to notify center prior to 'jumpers away.' by the time I could descend I had a total electrical failure due to a faulty voltage regulator. When I landed, I was advised that ZJX called the office to discuss the situation with the owner of the company. Callback conversation with reporter revealed the following information: the electrical failure, caused by a faulty voltage regulator, resulted in the lost communication. Reporter was unable to transmit, but sent the jumpers out anyway, which was contrary to the agreement between reporter's company and ZJX. Reporter says that after landing, ZJX had called her company, but only to verify that her aircraft had landed safely. No further action.

Title: ACFT EQUIP PROB. ELECTRICAL FAILURE WITH LOST COM.
Narrative: I FLY SKYDIVERS FOR X. ON THE DATE SPECIFIED HALF WAY THROUGH FLT I EXPERIENCED A PARTIAL ELECTRICAL FAILURE. I COULD HEAR ZJX CALLING MY ACFT BUT WAS UNABLE TO XMIT. AFTER SEVERAL ATTEMPTS ZJX ASKED ANOTHER ACFT TO CALL ME ON UNICOM. I SWITCHED TO UNICOM, COULD HEAR THE ACFT BUT WAS UNABLE TO XMIT. THE COMPANY HAS A LOA WITH THE FAA TO NOTIFY CTR PRIOR TO 'JUMPERS AWAY.' BY THE TIME I COULD DSND I HAD A TOTAL ELECTRICAL FAILURE DUE TO A FAULTY VOLTAGE REGULATOR. WHEN I LANDED, I WAS ADVISED THAT ZJX CALLED THE OFFICE TO DISCUSS THE SIT WITH THE OWNER OF THE COMPANY. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE ELECTRICAL FAILURE, CAUSED BY A FAULTY VOLTAGE REGULATOR, RESULTED IN THE LOST COM. RPTR WAS UNABLE TO XMIT, BUT SENT THE JUMPERS OUT ANYWAY, WHICH WAS CONTRARY TO THE AGREEMENT BTWN RPTR'S COMPANY AND ZJX. RPTR SAYS THAT AFTER LNDG, ZJX HAD CALLED HER COMPANY, BUT ONLY TO VERIFY THAT HER ACFT HAD LANDED SAFELY. NO FURTHER ACTION.
