What was found
OIL WAS DETERMINED TO BE LEAKING FROM THE PACKING AROUND THE BLADE AND NOT FROM THE CRANKSHAFT SEAL. PROPELLER WAS REMOVED FROM ENGINE AND DISASSEMBLED. HUB WAS CONFIRMED TO BE FILLED WITH ENGINE OIL. UPON FURTHER EXAMINATION, AN EXCESSIVE AMOUNT OF SCORING WAS FOUND ON THE PISTON ROD ASSEMBLY AND THE HUB AND THE PACKING WAS DAMAGED. IN ADDITION, METAL SHAVINGS WERE FOUND IN THE CYLINDER ASSEMBLY AND THE PISTON ASSEMBLY COULD NOT BE REMOVED FROM THE PISTON ROD ASSEMBLY. THIS IS THE SECOND PROPELLER FAILURE OF THIS KIND IN THE PAST YEAR.
