The real question is, did you flew in South America on a local license and legally logged those hours? ASA makes a logbook that is made to log hours flown under different regulators.
The only issue that I see is the type of logbook, in Brazil they wouldn`t allow me to present the hours I logged on my FAA/JAA logbook, I had to copy all the freaking hours on a CIV, after the first 10 pages I got sick of it and skipped all of them until the last page, none of the ANAC masters noticed anything. I had some students in the US that when they went to Europe they had to switch to a JAR logbook....but none of them ever had problems on any of the hours logged outside EU and reported on the JAR book.
Since 2009 I`m not using a paper logbook, just log everything on logbook pro, have converted into two licenses since then, I just print out my logbook and nobody ever said something...
