## Discrepancy

(CAN) WHILE THE AIRCRAFT WAS IN CRUISE FLIGHT, A BURNING ODOR WAS NOTICED IN THE CABIN. THE PILOT LANDED THE AIRCRAFT UNEVENTFULLY. THE BURNING ODOR WAS TRACED TO THE OVERHEAD LT FUEL PUMP SWITCH.  WHEN THE OVERHEAD PANELS WERE REMOVED A BURNED PUMP SWITCH CONNECTOR WAS SEEN.  CONNECTOR WAS REPLACED. THE RT SIDE WAS ALSO CHECKED AND IT WAS NOTED THAT THE CONNECTOR IS SHOWING SIGNS OF OVER HEAT.  TWO SEPARATE D.C. BUSES, PUMP SWITCHES AND PUMPS AFFECTED.
