## Discrepancy

AIRCRAFT WAS GROUNDED: FLIGHT ATTENDANT WAS UNABLE TO ARM DOOR 1L, AS WE CLOSED THE AIRCRAFT FOR DEPARTURE. SHE REPORTED RESISTANCE WITH THE 1L ARMING LEVER AND IT WOULD NOT STAY IN THE ARMED POSITION. THE CIDS PANEL AND FLIGHT DECK DOOR PAGE BOTH SHOWED 1L DOOR UNARMED WHEN THE LEVER WAS IN THE ARMED POSITION. MAINTENANCE REPLACED THE L1 DOOR SLIDE RAFT ASSEMBLY PER JOB CARD 26L00025011 (AALA202604084732) AND LUBRICATED THE ARMING MECHANISM (AALA202604087226). A SATISFACTORY OPERATION CHECK WAS ACCOMPLISHED WITH NO ISSUES NOTED.
