This is more for retired maintainers (military). How many have ended up getting skin cancer from not being able to wear head covers then fighting the VA for service coverage. I’ve been told with more letters from others in the field it’s possible, I’ve been told by my dermatologist it can take 20,30 even 40 years for skin cancer to show up which for me coincides with my service, I’ve had 18 surgeries just on my head and neck to get areas removed and the VA still says nope.

Ok all you GA guys, our flight school received these mufflers? Heat exchangers? from the company that sends us our 172 and Seminole mufflers, but we think they just got the contents mixed up. It was addressed to us and had no paperwork with them other than the tag saying the PN is 576. We’re just curious what the heck these go on?
