## Discrepancy

(CAN) RIGHT HAND PROPELLER HARD TO CONTROL, ENGINE SHUTDOWN, AND AIRCRAFT RETURNED TO BASE.  PRESSURE CHECK CARRIED OUT ON PROPELLER AND THERE WAS NO NITROGEN PRESSURE IN THE CYLINDER.  IT IS SUSPECTED THE VALVE WAS LEAKING.  THE VALVE WAS REPLACED, THE CYLINDER CHARGED WITH NITROGEN AND THE ASSEMBLY WAS CHECKED SERVICEABLE.
