## Discrepancy

RT HYDRAULIC PRESSURE FLUCTUATES AND DASHES WHEN SYSTEM IS PRESSURIZED WITH DCMP.  R EDP DOESN’T PRODUCE PRESSURE AT LOW POWER SETTING LOST HYDRAULIC PRESSURE ON THE RIGHT SIDE SYSTEM IN FLIGHT. INCREASING POWER ON THE RIGHT ENGINE BUILT PRESSURE BUT AS SOON AS POWER REDUCED THE PRESSURE WAS LOST AGAIN.
