## Discrepancy

PASSING FL280 LEFT ENGINE INSTRUMENTS RAPIDLY ROLLED BACK.  FLIGHT ATTENDANT REPORTED LEFT ENGINE ON FIRE.  LEFT ENGINE WAS SHUTDOWN.  AIRCRAFT RETURNED TO LAX.  *S/D*  UPON ARRIVAL AT LAX FOUND METAL IN THE TAILPIPE DUE TO AN HPC FAILURE, THE FIRE WAS INTERNAL DUE TO THE FAILURE.  THE ENGINE WAS REPLACED.  SHOP FINDINGS WERE THAT A 10TH STAGE HPC STATOR HAD FAILED.  THIS FAILURE IS A KNOWN MODE AND THIS EVENT IS STILL UNDER INVESTIGATION BY UA AND PWA.
