## Discrepancy

THE NUMBER ONE ENGINE WAS SHUT DOWN SHORTLY AFTER TAKEOFF DUE TO A COMPRESSOR STALL.  THE AIRCRAFT RETURNED TO DEN.  *S/D*  AFTER LANDING AT DEN METAL WAS FOUND IN THE TAILPIPE AND THE ENGINE WAS REMOVED AND SENT TO THE SHOP FOR INVESTIGATION AND REPAIR.  THE SHOP DISASSEMBLY FINDINGS WERE A FAILED 10TH STAGE HPC STATOR.  THIS IS AN INDUSTRY PROBLEM AND IS UNDER INVESTIGATION BY PWA.
