## Discrepancy

(CAN) GEAR WOULD NOT DROP WHEN SELECTED. GEAR DROPPED WITH EMERGENCY PROCEDURE.  WITH AIRCRAFT ON JACKS, THE GEAR WOULD CYCLE UP, BUT HYDRAULIC PRESSURE HAD TO BE RELEASED MANUALLY TO GET THE GEAR TO DROP.  POWER WAS FOUND GOING INTO THE VALVE BUT WAS NOT SHIFTING TO THE DOWN PORTS.  VALVE REPLACED.
