Narrative:

We had a ramp check at mci by the FAA. I had returned to the airport due to a rough running #1 engine. After being cleared for the visual approach and being told to contact tower, we had a loss of communications due to low battery voltage. Began checking the generators and discovered that the #1 generator was not carrying a load. We then turned off all unnecessary electrical equipment and landed the airplane. This occurred about 5 mi out and I squawked 7600 before landing. In the aircraft log I had written up the #1 engine, the #1 generator, and a right landing light. During the ramp check the engine log was not yet completed, however, it was completed before departure. The FAA at mci requested a copy of the engine log at a later date. They are now stating the radios should have been written as inoperative. I believe this to be incorrect. All electrical componentry was adversely affected by the low voltage. Callback conversation with reporter revealed the following information: reporter states when questioned about further developments that 2 FSDO offices went back and forth regarding the incident and finally threw out the entire incident.

Title: DC3 HAS ROUGH RUNNING ENG. RETURN LAND.

Narrative: WE HAD A RAMP CHK AT MCI BY THE FAA. I HAD RETURNED TO THE ARPT DUE TO A ROUGH RUNNING #1 ENG. AFTER BEING CLRED FOR THE VISUAL APCH AND BEING TOLD TO CONTACT TWR, WE HAD A LOSS OF COMS DUE TO LOW BATTERY VOLTAGE. BEGAN CHKING THE GENERATORS AND DISCOVERED THAT THE #1 GENERATOR WAS NOT CARRYING A LOAD. WE THEN TURNED OFF ALL UNNECESSARY ELECTRICAL EQUIP AND LANDED THE AIRPLANE. THIS OCCURRED ABOUT 5 MI OUT AND I SQUAWKED 7600 BEFORE LNDG. IN THE ACFT LOG I HAD WRITTEN UP THE #1 ENG, THE #1 GENERATOR, AND A R LNDG LIGHT. DURING THE RAMP CHK THE ENG LOG WAS NOT YET COMPLETED, HOWEVER, IT WAS COMPLETED BEFORE DEP. THE FAA AT MCI REQUESTED A COPY OF THE ENG LOG AT A LATER DATE. THEY ARE NOW STATING THE RADIOS SHOULD HAVE BEEN WRITTEN AS INOP. I BELIEVE THIS TO BE INCORRECT. ALL ELECTRICAL COMPONENTRY WAS ADVERSELY AFFECTED BY THE LOW VOLTAGE. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATES WHEN QUESTIONED ABOUT FURTHER DEVELOPMENTS THAT 2 FSDO OFFICES WENT BACK AND FORTH REGARDING THE INCIDENT AND FINALLY THREW OUT THE ENTIRE INCIDENT.
