one more point, I find that the stress on the steps is MUCH less if I use a low stool/box on the ground when possible.
If you watch the average guy mount his RV, you'll see a pretty good jolt to the step when you launch your weight from ground level up to the wingwalk. Starting from an 8" step, so you are only lifting your weight another 12" or so, really reduces this ''G'-load!
Just my $.02
I was advised against it by Vans.Thanks everyone. Has anyone used countersunk rivets?
I have read a lot here about steps cracking and the potential role that engine vibration and prop wash has as the cause. It was suggested to add some sand or shot inside the step to act as a vibration damper. I decided to go ahead and add some bird shot to the inside of my step. Below is a picture of the hole I drilled for adding the shot.
Will probably have to wait several years before I have a pirep, but it was simple enough to do.
