## Discrepancy

ON A 135 FLIGHT, PILOT REPORTED ODOR IN CABIN.  INITIATED PRECAUTIONARY LANDING UNEVENTFULLY.  UPON LANDING, PILOT NOTED HEATER CIRCUIT BREAKER TRIPPED.  INVESTIGATION REVEALED HEATER COMBUSTION AIR MOTOR FROZEN.  INSTALLED OVERHAULED MOTOR.  HEATER OPERATED NORMALLY.  NO FURTHER ODOR NOTED.  AS THE CIRCUIT BREAKER OPERATED NORMALLY, THERE WAS NEVER ANY THREAD OF FIRE.
