## Discrepancy

UPON DESCENT, THE SPEED BRAKES WERE OPENED WHEN COMMANDED TO CLOSE.  THE ACFT EXHIBITED A PRONOUNCED BUT CONTROLLABLE ROLL TO THE RT, FOLLOWED BY SPOILER FAIL MSG ON EICAS.  AFTER 15 - 20 SECS THE ACFT RETURNED TO NORMAL CONFIG & THE SPOILER FAIL MSG EXTINGUISHED.  PROBLEM REOCCURRED DURING LANDING ROLL OUT ALSO.  R & R SPEED BRAKE ACCUMULATOR ON RT SIDE IAW AMM 27-62-02.  OPERATIONS CHECKED GOOD, NO DEFECTS NOTED.
