   1. If there is a disconnect, damage, jam, corrosion and contamination, reconnect the disconnect, repair or replace the broken/defective components and treat corrosion/contamination and do close out.
   2. If there is no disconnect, damage, jam, corrosion and contamination, continue with next step.

2. Perform visual inspection of disconnect, damage, jam, corrosion and contamination of the following if there is a fault at the LRUs of the passenger door actuator assembly.

   • passenger door actuator including gearbox, electrical wiring, electronic pack, power supply and clutch
   • sprockets at the passenger door actuator and the middle shaft
   • chain at the passenger door actuator
   • middle shaft at the inner and outer sides of the passenger door airstairs
   • mechanical adjustment of the passenger door actuator mechanism (tension on the passenger door chain)
     NOTE: If the tension of the passenger door chain is adjusted, perform a check of the rigging of the passenger door actuator.

   1. If there is a disconnect, damage, jam, corrosion and contamination, reconnect the disconnect, repair or replace the broken/defective components and treat corrosion/contamination and do close out.
   2. If there is no disconnect, damage, jam, corrosion and contamination, continue with next step.

3. Perform visual inspection of disconnect, damage, jam, corrosion and contamination of the following if there is a fault at LRUs of the passenger door torque drum assembly.

   • torque drum
   • tensator drum
   • tensator springs
   • locating ring
   • mechanical adjustment of the passenger door tensator spring assembly (tension check)

   1. If there is a disconnect, damage, jam, corrosion and contamination, reconnect the disconnect, repair or replace the broken/defective components and treat corrosion/contamination and do close out.
   2. If there is no disconnect, damage, jam, corrosion and contamination, continue with next step.

4. Perform visual inspection of disconnect, damage, jam, corrosion and contamination of the following if there is a fault of the passenger door proximity sensors.

   • electrical wiring
   • mechanical adjustment of the passenger door proximity sensors (clearance check)

   1. If there is a disconnect, damage, jam, corrosion and contamination, reconnect the disconnect, repair or replace the broken/defective components and treat corrosion/contamination and do close out.
   2. If there is no disconnect, damage, jam, corrosion and contamination, continue with next step.

5. Perform visual inspection of disconnect, damage, jam, corrosion and contamination of the following if there is a fault at LRUs of the passenger door assembly. Handrails that need lubrication, are bent or damaged will cause excessive resistance when closing the door. Watch the handrail when closing and opening the door and make sure there is no jerking or slipping motion. They should fall free when opening the door with no resistance. Supporting the door halfway up will facilitate inspection and lubrication of the handrail.

   • Check the Telescopic strut for damage
   • Check for binding or excessive play in the pivots
   • Perform the Lubrication of the Passenger Door Handrail Telescopic Struts as per AMM
     NOTE: Make sure to use a non-staining (Clear) dry lubricant when lubricating.

   1. If there is a disconnect, damage, jam, corrosion and contamination, reconnect the disconnect, repair or replace the broken/defective components and treat corrosion/contamination and do close out.
   2. If there is no disconnect, damage, jam, corrosion and contamination, continue with next step.

6. Perform a check of the handrail stops and make sure that there is proper clearance when the door is closed. If there is no gap, it could be difficult to close the door from the outside. Make sure that you adjust both sides of the handrail equally. If you do not, you can cause damage to the handrail. Refer to AMM handrail rigging task.

   1. If system checks are good, do close out.
   2. If fault remains, continue with next step.

7. Perform a visual inspection of the guide pins and make sure the button on the end of the guide pin is not unscrewed and preventing the door from closing during the last portion of the door travel before latching.

   1. If system checks are good, do close out.
   2. If fault remains, continue with next step.

8. Perform visual inspection of disconnect, damage, jam, corrosion and contamination of the following if there is a fault at the passenger door cables or at the cable assembly LRUs.

   • forward and aft passenger door cable
   • forward and aft cable pulley
   • mechanical adjustment of the passenger door cables (rigging of the passenger door cables)

   1. If there is a disconnect, damage, jam, corrosion and contamination, reconnect the disconnect, repair or replace the broken/defective components and treat corrosion/contamination and do close out.
   2. If there is no disconnect, damage, jam, corrosion and contamination, continue with next step.

9. Perform visual inspection of disconnect, damage, jam, corrosion and contamination of the following if there is a fault at passenger door bottom step or the assembly LRUs.

   • passenger door bottom step
   • drive arm
   • folding step shaft
   • mechanical adjustment of the passenger door bottom step (rigging of the passenger door bottom step)

   1. If there is a disconnect, damage, jam, corrosion and contamination, reconnect the disconnect, repair or replace the broken/defective components and treat corrosion/contamination and do close out.
   2. If there is no disconnect, damage, jam, corrosion and contamination, continue with next step.

10. Perform visual inspection of disconnect, damage, jam, corrosion and contamination of the following if there is a fault at passenger door switches.

    • passenger door switches

    1. If there is a disconnect, damage, jam, corrosion and contamination, reconnect the disconnect, repair or replace the broken/defective components and treat corrosion/contamination and do close out.
    2. If there is no disconnect, damage, jam, corrosion and contamination, continue with next step.

11. Perform visual inspection of disconnect, damage, jam, corrosion and contamination of the following if there is a fault at passenger door connection points

    • forward and aft passenger door hinges
    • top, the bottom, the forward side, and the aft side abutments (14 in total)
    • adjustment of the passenger door abutments (rigging of the passenger door abutments)

    1. If there is a disconnect, damage, jam, corrosion and contamination, reconnect the disconnect, repair or replace the broken/defective components and treat corrosion/contamination and do close out.
    2. If there is no disconnect, damage, jam, corrosion and contamination, continue with next step.

12. Perform a visual of the top step hinges for wear, corrosion and binding condition. Please note SB 700-52-041 introduces new eccentric bushings for improved alignment and durability. Remove top step screws and try to lift the step to check hinge stiffness.
    NOTE: Do not close the door with top step half connected. Remove fully or re-attach before attempting to close the door.

    1. If the door is able to lift or stalls, do close out.
    2. If the door cannot lift or stalls, check the door for excessive weight and continue with next step.

13. Inspect storage bins for added weight (tools and supplies) that may exceed weight limitation. Door may have been exposed to the elements or water may have leaked through the flapper door. Water can retain in the insulation bags. Moisture will not dry out quickly due to limited airflow. Excess weight may prematurely degrade the door motor. Inspect the insulation bags below the flapper door. To perform a quick inspection, lift the lower door step, reach in and squeeze the exposed bags and the outer shell bags through one of the lightening holes on the side.If water is found, remove and dry out the bags or replace bags.
14. Perform the tests that follow to make sure that the passenger door closes satisfactorily:

    • Operational test of the passenger door
    • Functional test of the passenger door

15. Do close out.
