## Discrepancy

AIRCRAFT WAS NOT GROUNDED.  SPEEDBRAKE ARMED LIGHT DID NOT ILLUMINATE WHEN THE SPEEDBRAKE WAS ARMED FOR LANDING.  AFTER LANDING, THE SPEED BRAKE HAD TO BE DEPLOYED MANUALLY.  SUPPLEMENTAL REPORT: REPLACED SPEEDBRAKE ARM SWITCH AND ACCOMPLISHED ADJUSTMENT AND TEST PROCEDURE, IAW AMM 27-62-00.  OPERATIONS CHECK GOOD.
