I'm working on Army Aviation corrosion prevention topics for a conference and would like to ask what are units having issues with?

As MAJ Ken Landgren mentioned, the 160th SOAR does have corrosion issues, they had a corrosion symposium in 2014. You can also contact AMCOM corrosion program and they would be able to help. Also on Facebook CH-47 Hookers, its a closed group but you can message, this group has CH47 crew members from active duty, reserves and guard.

COL Mike Humphrey Sir, I hope you don't mind my tagging you here but I didn't see responses to MAJ (Join to see) 's question, maybe you could give him some insight or direction.
