What was found
DURING PREFLT INSP, MAINT CREW NOTED THAT SPOILERS FULLY DEPLOYED IN LESS THAN 1 SECOND WITH SPOILER SWITCHES SET TO "IN-FLT" MODE. NORMAL DEPLOY TIME IN THIS MODE IS 6-10 SECONDS WHEREAS "GROUND AUTO-DEPLOY" MODE FOR LANDING IS LESS THAN ONE SECOND. IN PROCESS OF TROUBLESHOOTING, IT WAS DETERMINED THAT HYD RESTRICTOR IN SPOILER SYS WAS NOT RESTRICTING FLOW IN DEPLOY MODE BUT WILL RESTRICT IN RETRACT MODE. FURTHER INVESTIGATION DETERMINED THAT RESTRICTOR HAD FAILED. IT APPEARS THAT THE INTERNAL FILTER SCREENS IN THE RESTRICTOR DEFORM ALLOWING THE RESTRICTOR AND DIVIDER PLATES TO FLOAT BACK AND FORTH AND DEFORM TO THE POINT THAT RESTRICTOR AND DIVIDER PORTIONS BREAK AWAY FROM THEIR PLATES.
