## Discrepancy

THE FLIGHT CREW REPORTED THAT THE RIGHT SPEED BRAKE/SPOILER INDICATION DID NOT APPEAR ON THE EICAS DURING FLIGHT CONTROL CHECK HOWEVER THEY ARE VERIFIED VISUALLY DEPLOYED.  IN FLIGHT NO SPEED BRAKE/SPOILER INDICATION IS DISPLAYED. THE MAINTENANCE VENDOR EVALUATED AND DETERMINED THAT THE RIGHT SPEED BRAKE/SPOILER INDICATOR SWITCH WAS INTERMITTENTLY FAILING CAUSING THE INDICATION FAULT. THE MX VENDOR REPLACED THE SWITCH WITH NEW UNIT. RIGGED SWITCH, OPERATIONAL CHECKS OK. AIRCRAFT WAS RETURNED TO SERVICE.
