Change Models Make functionality
After using the Change Models make (which creates a duplicate of the Model under the the new make)
You should open the new Model in system tables to make sure everything is correct.
(Below the Mod Eligible was not set correctly and you need to modify it to All MODS
Then you will need to open the project that should use that make and de-select the old Make/model and select the new Make/model.
The application will not change all historical instances of the original Make/Model with the new values.
(NOTE: If you do not have update access to System tables and are a NAPA System Administrator, you need to search for yourself in the TC person module and change your TC group to Aircraft Certification save.
Then logout and restart NAPA)
