## Discrepancy

AIRCRAFT WAS GROUNDED: CAUTION LIGHT ILLUMINATED ON CIDS PANEL BUT THERE WAS NO FLIGHT DECK INDICATION. MAINTENANCE SERVICED THE RIGHT HAND FORWARD (AALA202503092071) AND AFT (AALA202503109372) EMERGENCY DOOR DAMPER AND EMERGENCY OPERATION CYLINDERS PER AMM 52-22-00-614-002-A, WHICH CLEARED THE FAULT ON THE CIDS.
