AS THE FLIGHT RETURNED TO THE AIRPORT THE LANDING GEAR AND FLAP TRIM FAILED TO RESPOND. THE PILOT CONFIRMED A COMPLETE LOSS OF ELECTRICAL POWER AND WITH SMOKE AND FUMES IN THE COCKPIT ELECTED TO LAND GEAR-UP. INVESTIGATION REVEALED A SHORT BETWEEN THE ALTERNATOR FILTER ASSEMBLY. ONE OF THE INTERNAL WIRES WAS FOUND SHORTING TO THE CASE.
