Narrative:

While ferrying an small transport from ric to rdu, 4500' VFR, I had a complete electrical failure. The failure occurred approximately 50 NM from rdu. I continued toward rdu by dead reckoning and by cycling switches, etc. I regained partial electrical power for approximately 40 seconds. I had the DME and 1 radio. I saw I was 11.5 NM from rdu. I called approach control and explained problem, stating that I would probably lose total electric power before landing. I was told to expect runway 5L, given a vector for a left pattern and to drop to 2500'. I did, then lost power again. I pumped the gear down, looked for traffic and lights, then landed on 5L with no lights or electrical power. Taxied clear and parked the aircraft. Rdu approach control and tower did a great job.

Title: SMT PLT ON FERRY FLT EXPERIENCES ELECTRICAL FAILURE.

Narrative: WHILE FERRYING AN SMT FROM RIC TO RDU, 4500' VFR, I HAD A COMPLETE ELECTRICAL FAILURE. THE FAILURE OCCURRED APPROX 50 NM FROM RDU. I CONTINUED TOWARD RDU BY DEAD RECKONING AND BY CYCLING SWITCHES, ETC. I REGAINED PARTIAL ELECTRICAL PWR FOR APPROX 40 SECS. I HAD THE DME AND 1 RADIO. I SAW I WAS 11.5 NM FROM RDU. I CALLED APCH CTL AND EXPLAINED PROB, STATING THAT I WOULD PROBABLY LOSE TOTAL ELECTRIC PWR BEFORE LNDG. I WAS TOLD TO EXPECT RWY 5L, GIVEN A VECTOR FOR A LEFT PATTERN AND TO DROP TO 2500'. I DID, THEN LOST PWR AGAIN. I PUMPED THE GEAR DOWN, LOOKED FOR TFC AND LIGHTS, THEN LANDED ON 5L WITH NO LIGHTS OR ELECTRICAL PWR. TAXIED CLR AND PARKED THE ACFT. RDU APCH CTL AND TWR DID A GREAT JOB.
