## Discrepancy

DURING CRUISE FLIGHT THE PASSENGERS IN THE AFT CABIN REPORTED TO THE PILOT SMELLING SOMETHING BURNING AND THEN REPORTED SMOKE IN THE AFT CABIN AREA. PILOT PERFORMED A PRECAUTIONARY LANDING IN AN UNIMPROVED AREA DUE TO REMOTE LOCATION OF AIRCRAFT AT THAT TIME. DURING MAINTENANCE INSPECTION OF THE AIRCRAFT FOUND THAT THE MEDICAL SUCTION PUMP CIRCUIT BREAKER WAS TRIPPED AND WOULD NOT RESET AND UPON FURTHER INSPECTION FOUND THE VACUUM PUMP TO HAVE BEEN THE CAUSE OF THE BURNING ODOR AND SMOKE ACCUMULATION. VACUUM PUMP INSTALLED.
