## Discrepancy

DURING CLIMB OUT,  HAD A CHEMICAL ODOR IN THE COCKPIT.  RETURNED TO DEPARTURE.  APU WAS OFF AFTER ENGINE START & NOT USED ON THE GROUND FOR BLEED AIR.  THERE WAS NO VISIBLE SMOKE.  INSPECTED AND FOUND OIL RESIDUE IN THE APU INLET. REMOVED AND REPLACED THE APU IAW MM 49-10-00. OPS AND LEAK CHECKED GOOD. NO ODOR DETECTED AT THIS TIME.
