What was found
MAIN HYD ACCUMULATOR SEEMS TO BE DROPPING PRESSURE MORE QUICKLY THAN NORMAL. AS PRESSURE DROPS WE LOSS BRAKE EFFECTIVENESS UNTIL PUTTING PUMP IN OVERRIDE. DURING FLIGHT MAIN ACCUMULATOR GOT TO THE POINT WHERE IN AUTO MODE WAS KICKING BACK ON EVERY 3 MINUTES. DURING LANDING NO ISSUES WITH BRAKES. DURING TAXI IN WITH HYD PUMP IN AUTO THE MAIN ACCUMULATOR WOULD DROP PRESSURE MORE OFTEN THAN NORMAL AND NEED TO PLACE PUMP IN OVERIDE TO MAINTAIN ENOUGH PRESSURE FOR PARKING.
