Default Step broke off

Climbing aboard yesterday when the left step broke off. I got some nasty shin damage but the flap survived.

The airfoil shaped drop down piece broke away from the tube that inserts into the fuselage. It looks like when it was manufactured, they weld a flat plate across the tube then weld the airfoil shaped drop down piece to that flat plate. The flat plate held but the drop down sheared off of the plate. It sort of looks like they ground a little too much of the weld away. This had been cracked a long time as it was rusty along 2/3 of the contact area.

Look yours over for any signs that the weld is failing, i.e. rust stains or visible cracks.

PM for photos.

I had mine break also, I attribute that to too much cosmetic grinding or removal of weld to smooth surface during construction. Had to get rewelded and so far so good.

I called Van?s and they seemed to have never heard of this. I came to the same conclusion, they ground off the weld. My shins paid a dear price to the trailing edge of the flap. Luckily it didn?t damage the flap.

Convenient ignorance. They denied any issue for years on the 6-7-9's too, while the demonstration planes had applied a reasonable fix. Finally agreed to a fix.

Look up Russ McCutcheon here on VAF and see if he will apply the same fix as the other models.

So, for those of you who have seen this failure on -10 steps, were was the initial crack located?

There a enough reports about steps breaking that I took the time and effort to reinforce TIG weld the steps on my RV-10 before I installed them. On my RV-9A project, the steps were already installed by the previous builder so I took the trouble to drill out the baggage compartment floor pans, drill out the step mounting plates, remove and reinforce TIG weld those steps. I didn't want to risk the possibility of those breaking after the plane is flying and painted. One thing I did on re-installation was using a thin film of Pro-Seal between the step mounting plate and the fuselage skin before riveting. Moisture will never find its way in there.

The step on our 7A (right side) developed a crack at the top. Lots of posts on this in VAF. We ordered a new ?re-enforced? step and installed it. Install is easy but time consuming to match drill the new step. I am told it is a fatigue issue with prop wake harmonics.

Just curious, how long has the plane been flying? If you e-mail me a picture I can get it posted for you, just curious what it looks like.

Thanks,
Lynn
