## Discrepancy

(CAN) DURING CRUISE IT WAS NOTICED THAT THERE WAS A SLIGHT SHAKE AND DEVELOPED AN OIL LEAK, A PRECAUTIONARY SHUT DOWN WAS CARRIED OUT AND PROP FEATHERED, UPON INSPECTION IT WAS FOUND THAT THE LOWERS STUDS WERE BROKEN ON THE CYLINDER ASSEMBLY. CURRENTLY AN INVESTIGATION INVOLVING THE OVERHAUL FACILITY IS BEING CARRIED OUT. THE STUDS WERE REPLACED ALONG WITH THE CYLINDER ASSEMBLY.
