Fix required for rudder hydraulic leaks

The FAA requires certain Airbus Canada Model BD-500-1A11 airplanes to have the rudder hydraulic fittings on all three rudder hydraulic power control units (PCUs) properly torqued and a torque seal applied. This action responds to a hydraulic fluid leakage event that pointed to possible use of an uncalibrated torque wrench when those union fittings were tightened.
