## Discrepancy

(CAN) THE PROPELLER BLADE SEAL HAD SPRING INSIDE OF IT AND THE TWO ENDS ARE WELDED TOGETHER BY THE MANUFACTURE. THE SPRING BROKE AT THE WELDED JOINT CAUSING OIL TO LEAK OUT OF THE HUB AT THE BLADE ROOT. IT WAS NOTICED DURING A D.I AFTER THE FLIGHT. THE SEAL AND SPRING ASSY WAS REPLACED AND THE A/C RETURNED TO SERVICE.
