## Discrepancy

COCKPIT ODOR BURNING SMELL - THERE IS A STRONG SMELL OF FUMES IN THE COCKPIT AND CABIN. THERE IS A SMELL OF EXHAUST OR BURNT FUEL THAT COMES AND GOES IN THE AIRCRAFT, STRONG ENOUGH THAT IT MAKES YOUR EYES BURN. IT IS STRONGER WHEN THE THERMOSTAT KICKS THE HEAT ON. IT IS STRONG ON THE GROUND WITH THE APU AND BLEED AIR ON OR IN THE AIR (IN-FLIGHT) WITH THE APU OFF. IN-FLIGHT IS WHEN THE EXHAUST SMELL IS THE STRONGEST.  PERFORMED ECS SYSTEM BURN OUT TASK CARD & INSTALLED NEW CONDENSER BAGS.  INSPECTED APU INLET & APU BLEED OUTLET WITH NO DEFECTS.  OPS, LEAK, & ODOR CHKS SATISFACTORY.
