Bill Hogarty, I would add to your list:

-The filter in the Dukes cabin pressure controller-annual change
recommended.
-ELT battery-varies by manufacturer and type
-


Don't know the appropriate change intervals for the following, but each has
performance characteristics that degrade over time:

-Accessory drive belts (if any)
-Hydraulic fluid
-Brake fluid
-Door seal

Hope this helps.
