## Discrepancy

(CAN) DURING RENTAL ENGINE RE-CERTIFICATION INSPECTION, THE PROPELLER SHAFT FLANGE WAS FOUND CRACKED.  THE CRACK WAS 2.50 INCHES LONG CIRCUMFERENTIALLY FOLLOWING RADIUS OF SHAFT TO THE FLANGE.  NO PROP STRIKE INCIDENTS WERE RECORDED IN THE LOG BOOKS.   PRELIMINARY INDICATIONS WERE THAT THE PROP SHAFT WAS PURCHASED FROM A VENDOR IN AN OVERHAULED CONDITION.  P&W REQUESTED AN INVESTIGATION  INTO THE OVERHAUL PROCESSES.
