## Discrepancy

ON THE WAY TO PICK UP A PATIENT, IN CRUISE FLIGHT AT NIGHT, THE MEDICAL CREW IN THIS AIR AMBULANCE HELICOPTER DETECTED A BAD SMELL AND THEN SAW SMOKE IN THE AFT CABIN AREA.  THE PILOT SHUT DOWN THE ELECTRICAL SYSTEM.  AN UNSCHEDULED LANDING WAS MADE INTO A LARGE, WELL LIT, VACANT PARKING LOT AT A LOCAL HIGH SCHOOL.  MAINTENANCE DETERMINED SMOKE TO BE FROM STROBE POWER SUPPLY. REPLACED POWER SUPPLY.
