Narrative:

Had electrical problems on IFR flight plan. Tried to cancel, did not communicate. Return to departure airport. No accidents. I was under impression that I had canceled my IFR flight plan. ZME said that they did not receive. Callback conversation with reporter revealed the following information: reporter states that he was flying a centurion C210. The problem was with the alternator. He called the FSS after landing to be sure the IFR flight plan was canceled. Since this was an electrical failure he was not sure if the message got through to cancel. Some time later, ZME contacted him and said they had not received his cancellation until FSS contacted them.
