As you are an aerospace manufacturer you may be conformally coating the boards.
If so, you may be interested to know that HumiSeal has just completed a study with the NPL (National Physical Laboratory) into the interaction between tin whiskers and conformal coating.
Results show that conformal coatings will abate tin whisker growth and although various conformal coating chemistry types perform in different ways with tin whiskers, they all abate growth.
Please contact us if you would like full information on this project.
