## Discrepancy

IN FLIGHT DURING INITIAL CLIMB OUT, THERE WAS A CABIN ODOR PRESENT THAT SMELLED OF BURNING RUBBER.  ODOR WAS STRONG & PERSISTED THROUGHOUT FLIGHT & THE RETURN TO AIRPORT.  ODOR SEEMED STRONGER IN CABIN.  REPLACED SEPARATED PRECOOLER WITH NEW UNIT IAW MM 34-11-05. OPS AND LEAK CHECKS ARE GOOD. NO ODORS ARE NOTED DURING ENGINE RUNS WITH BLEEDS ON.
