## Discrepancy

(CAN)DURING BOROSCOPE INSPECTION OF THE COMPRESSOR TURBINE VANE RING FOUND WHAT APPEARED TO BE A CRACK OF THE RING. UPON REMOVAL OF THE TURBINE WHEEL THE RING WAS FOUND SERVICEABLE, BUT FURTHER INSPECTION  FOUND A DIFFUSER PIPE WELD AT THE DUCT TO BE CRACKED. THE CRACK EXTENDED 90 PERCENT OF THE WELD. THE DIFFUSER PIPE REMAINS TIGHT IN THE DUCT ASSEMBLY DIFFUSER EXIT.
