A C310 PLT; WHILE POSITIONING ACFT AT ALB; STRUCK A PORTABLE HELI PAD.

Narrative

AFTER PREFLT; AND RECEIVING MY CARGO; I STARTED THE ACFT. APPROX 1 SECOND AFTER TURNING ON THE AVIONICS MASTER; STROBE; NAVS AND TAXI LIGHTS; A SHOWER OF SPARKS FELL ON MY SHOES FROM UNDER THE CONSOLE. AFTER SHUTTING DOWN; I CALLED OPS AND WAS TOLD TO TAXI DOWN TO MAINT. I WAS PARKED AT A NON-MOVEMENT AREA. MAINT IS LOCATED APPROX 500 YARDS N IN THE SAME NON-MOVEMENT AREA. WITH THIS IN MIND; I RESTARTED THE ACFT AND TURNED ON THE NAVS; STROBES (ANTI-COLLISION); AND TAXI LIGHT. WITHIN 30 SECONDS OR SO; THE GEAR WARNING SYS CIRCUIT BREAKER POPPED. AS I LINED UP ON THE TXWY ALONG THE NON-MOVEMENT AREA; I NOTICED A B737 PARKED NEAR THE TXWY ON THE L. ALSO; AS I TAXIED PAST THE B737; A SECURITY VEHICLE DROVE TOWARD ME ON THE TXWY. I WATCHED MY WINGTIP CLR THE B737 AS ANOTHER CIRCUIT BREAKER POPPED AND I NOTICED THE SCENT OF SMOKE. THE VEHICLE MOVED INTO THE PARKING AREA TO THE L NEAR MAINT. JUST THEN; I NOTICED A FLASH OF YELLOW ON THE R SIDE. I APPLIED FULL BRAKING; AND EVEN THOUGH I WAS TAXIING AT IDLE; DID NOT STOP IN TIME. I STRUCK A TOWABLE HELI PAD WHICH WAS PARKED ON THE TXWY. CONTRIBUTING FACTORS INCLUDE MULTIPLE DISTRS (CIRCUIT BREAKERS; SMOKE; ACFT PARKED NEAR TXWY; VEHICLES ON TXWY) AND BAD LIGHTING (SECURITY VEHICLE COMING HEAD-ON; AND INTERNAL LIGHTING RHEOSTATS STUCK ON HIGH); AND MY LACK OF COLLISION AVOIDANCE.
