Node translation access module allows to control access to nodes for selected languages

In this case, node will be visible on all available languages no matter whether it has translation or not. Using entity translation module you can deny access to nodes of selected language. You can deny access to languages per node. Users will see standard access denied page.

from its initial language to any translation.
With this module, the user will avoid having to fill in the field's data for all of the content's translations.
