## Discrepancy

THE MUFFLER TAILPIPE IS CHAFING ON THE FIREWALL.  A WEAR SPOT WAS FOUND ON INSPECTION.  THE ENGINE WAS GROUND RUN AT OPERATING TEMPERATURE WHICH CAUSED THE MUFFLER TAILPIPE TO EXPAND UP TO 13 MM CAUSING IT TO TOUCH FIREWALL AT FRAME NR 1. SUBMITTER RECOMMENDS REPOSITIONING TAILPIPE DOWN MORE TO PREVENT THIS DEFECT.
