Jeez,
I dont even let my logbook out of my sight when i'm at our beloved CAA! let alone some tin pot outfit on the other side of the world.
I have seen quite a few packages go missing or get damaged, even with the best will in the world these things do happen.
So tough boobs basically! if it was me....they will have to make do with a photocopy for now, then i would offer to pitch up a few days early with the originals in hand to get the documentation drama over with.
Good luck!
