Fuselage, MID Lower Structure (Part 31)

With the Step Attach Assemblies completed and riveted the F-01405 Bulkhead, it’s now time to install the remaining Baggage Ribs.

The first to go in are the F-01427-L & -R Baggage Ribs.  The were attached with a mixture of AN470AD4-4 and LP4-3 rivets.  The plans excerpt shows their installation location.
Next, the two F-01426-L & -R Baggage Ribs are attached to the Bulkhead with AN470AD4-4 solid rivets.


Lastly, here is the ALMSOT completed MID Lower Structure after the Baggage Ribs described above were installed.  The last step is to install the F-01430 Baggage Floor Stiffener.  In the picture below, you can see the Stiffener installed midway down the Baggage Ribs running horizontal across the baggage area.  The Baggage Floor Stiffener is attached to the F-01458-L & -R Side Frames and F-014234B-L & -R Outboard Baggage Ribs using two LP4-3 on each side.
