## Discrepancy

(CAN) THE RT STARTER-GENERATOR OF THE RT ENGINE WAS REMOVED DURING SCHEDULED MAINTENANCE.  ALSO, REMOVED WAS THE STARTER-GENERATOR MOUNTING ADAPTER TO ALLOW BETTER ACCESS FOR ENGINE MAINTENANCE AND INSPECTION.  AFTER REMOVAL, IT WAS FOUND THAT THE MOUNTING ADAPTER WAS CRACKED IN 1 OF THE 6 LUGS COMPLETELY THROUGH.  THE MOUNTING ADAPTER ANTI-ROTATION PINS ALSO SHOWED SOME WEAR.  TROUBLE IN SEEING THE DEFECT UNLESS REMOVED WAS DUE TO THE MOUNTING ADAPTER LUGS BEING COVERED BY A COOLING SHROUD AND THE INSIDE OF THE ADAPTER IS USUALLY DIRTY FROM STARTER-GENERATOR BRUSH DUST.  ACFT TT IS 9586.7.  TIME SINCE NEW OF THE ADAPTER IS UNKNOWN. TIME SINCE O/H OF THE ADAPTER, ENGINE TIME.
