## Discrepancy

PILOT REPORTED HEAVY EXHAUST FUMES ENTERING CABIN THROUGH BLEED AIR SYSTEM.  THIS WAS THE THIRD REPORT IN A ROW.  PREVIOUS REPAIRS INCLUDED REPLACING A CRACKED EXHAUST STACK.  COULD NOT DUPLICATE ON GROUND.  THE FINAL DISCREPANCY REPAIRED WAS TO REPLACE NR 1 ENGINE FUEL NOZZLE SEALS.  THE FINAL DISCREPANCY WAS VERIFIED ON GROUND RUNS AS WAS THE CORRECTION.  (M)
