## Discrepancy

DURING LINE CHECK, MAINTENANCE FOUND THE CATWALK STUCK IN THE LOWERED POSITION WITH THE AFT AIRSTAIRS LOWERED.  ON INSPECTION, MAINTENANCE FOUND THE RIGHT RETRACT CABLE JAMMED.  MAINTENANCE REPLACED THE FITTING CRANK ASSEMBLY AND RETRACT CABLE AND RETURNED THE AIRCRAFT TO SERVICE AFTER A SUCCESSFUL FUNCTIONAL CHECK OF THE SYSTEM.
