What was found
AIRCRAFT WAS GROUNDED: LEFT AFT CABIN DOOR (4L) DID NOT INDICATE ARMED DURING DESCENT, BUT DID INDICATE ARMED FROM PUSHBACK THRU CRUISE.

MAINTENANCE NOTED THAT WITH THE DOOR CLOSED THE SLIDE ALIGNED WITH THE DOOR FRAME AND THAT THE SLIDE REQUIRED ADJUSTMENT. MAINTENANCE REMOVED, RE-INSTALLED AND ADJUSTED THE SLIDE AND GIRT BAR ASSEMBLY PER AMM 25-62-44. A SATISFACTORY OPEATIONAL CHECK WAS ACCOMPLISHED.
