Rails 3.1, typus gem localization

Hello, guys.

I was trying to adapt administration backend with typus
http://typus.readthedocs.org
But, got stucked with localization problem. If I make localization in
/config/locales/ru.yml:
ru:
  activerecord:
    models:
      maintenance: Обслуживание

It localizes only that model name. But i want this model appear in typus
"Applications" section. Config/typus/maintenance.yml now looks like:
Maintenance:
  fields:
    default: description, price
    form: description, price
  application: Maintenance

But where should i make localization if i want this model show like:
application: Обслуживание

Help, pls
