## Discrepancy

(CAN) ENGINE COULD NOT ATTAIN TAKE OFF RPM. PROPELLER WAS REMOVED AND BENCH TESTED. IT WAS FOUND THAT IT WOULD NOT CYCLE INTO FINE PITCH. UPON DISASSEMBLY IT WAS FOUND THAT THE BEARING RACES, RETAINERS AND BALLS WERE SEVERELY CORRODED. PROPELLER WAS REASSEMBLED USING NEW REPLACEMENT PARTS AND FUNCTION CHECKED.
