Step bolt access

[Machsandy]

We have a wee bit of play on our left step and I believe this may ba a common issue.

How do people access the bolt to replace or bush on a completed aeroplane?

I intentionally cut 3/4" or thereabouts holes in the floorboards and belly of the airplane in anticipation of this issue. Snap plugs close the holes and my trusted factory resource saw no challenge with that approach.

Should be an easy mod to retrofit if you can get measurements for where to drill. I'd measure mine, but am out of town for a few days.

Thanks Kyle that sounds a very sensible approach. Sadly, I am guessing that here in the UK that would require a modification approval from our regulator, the Light Aircraft Association?

However it may be an option?

Not that I'm a big rule breaker, but that one wouldn't exactly jump out at most inspectors.

Where are you in England, out of curiosity? I'm posting from London right now.

It?s actually described in the instructions as a way for access. So you might not need any additional inspections.

I'm about to install my floor panels and heard about this happening. I ordered (and received quickly) 2 "step bushings" from TCW Technologies. A friend of mine installed them and says they're great. He also installed an access panel in the floor and a small hole under the fuselage, to access later if needed to tighten. I plan to do the same.

I added a small floor panel over the bolt.
It gives access for install/tightening of the step bolts as well as the com antenna installed in the same left and right bays.

I did the same with a opening large enough to get both wrenches in there. I used quite a few CS pull rivets, so it should easily hold the loads placed on the floor with cargo.

I used one inspection panel supplied in the kit since I did not install the wing stall-warning indicator. They are cheap and easy to install in the baggage area with lots of room for wrenches, and can all be done with solid rivets and squeezer (nothing against CS rivets, but solid if I can). Also is great access to the area for wiring too, like an ELT antenna or......... Always good just in case you do need to do something in that area, great your looking ahead!

I figure the Engineering is solid. The whole baggage floor is held on with pull rivets, so I assumed they were adequate for the load back there.
