varigflyer, fortunately, if you fill it out wrong there is a good chance the FAA Inspector will give you a new form with directions.
It is pretty self explanatory-- there are detailed instructions on the form itself that should be read carefully, however, here is a quick briefing:
For Certificate/ Rating applied for "X" "Other" and write in SIC Type Rating.
The other things are as per the instructions on the form in Section 1. If you have a PO Box, they will want a physical explanation of where you live. Height and Weight in Inches and pounds. Your Citizenship is the country where you live, ie. "Brazil", NOT "Brazilian."
For Part II, I "X" box "E", put the name of the Air Carrier (I assume in your case it is "Varig" and the last date of your recurrent. For the Curriculum, leave it blank if it was a Recurrent, or check it if it was an Initial or Transition.
I had success the second time around, just make sure you have one of your Company signing authorities sign the Instructor's recommendation on the back of Form 8710!
