## Discrepancy

AIRCRAFT WAS GROUNDED: DURING A FUNCTIONAL CHECK OF THE L1 DOOR, MAINTENANCE FOUND THE DOOR DAMPER AND EMERGENCY OPERATION CYLINDER DAMPING FUNCTION FAULTY WHICH RESULTED IN REQUIRING EXCESSIVE FORCE TO MANEUVER THE DOOR INTO THE OPEN POSITION AND CAUSING THE DOOR TO CONTACT THE FUSELAGE. MAINTENANCE REPLACED THE L1 DOOR DAMPER AND EMERGENCY OPERATION CYLINDER PER AMM 52-11-14. A SATISFACTORY OPERATIONAL CHECK WAS ACCOMPLISHED.
