THE MESSERSCHMITT-BLOHM-BOELKOW BO-105C WAS ON AN AIR AMBULANCE FLT WITH A PLT, 2 ADDITIONAL CREWMEMBERS (DOCTOR & NURSE) & A PASSENGER (PATIENT) ON BOARD. DURING FLT, THE PLT RADIOED THAT HE HAD LOST POWER IN 1 ENG, THEN ABOUT 14 SEC LATER, HE RADIOED THAT THE OTHER ENG HAD ALSO LOST POWER. DURING A FORCED LANDING/AUTOROTATION TO A ROAD AT NIGHT, THE HELICOPTER COLLIDED WITH POWER LINES & CRASHED. NO FUEL WAS FOUND IN THE RIGHT SUPPLY TANK & ONLY ABOUT 1 GAL OF FUEL WAS FOUND IN THE LEFT SUPPLY TANK. THE MAIN TANK HAD 15.4 GAL REMAINING, BUT THE RESPECTIVE FUEL BOOST PUMP SWITCHES WERE FOUND IN THE 'OFF' POSITION. THE REAR MAIN FUEL TANK HAD ONLY SLIGHTLY OVER 1 GAL REMAINING. ALSO, AN ELECTRICAL WIRE IN THE LOW FUEL WARNING CIRCUIT WAS NOT CONNECTED. THE FUEL SUPPLY TO EACH ENG IS FROM THE FUEL SUPPLY TANKS, WHICH ARE INDEPENDENT OF EACH OTHER.
