Default RV-9A Nose Wheel Rotates 360 Degrees - Normal?

Becoming more familiar with my newly acquired RV9A. Yesterday, in gently pushing the aircraft backwards without using the tow bar, nose wheel rotated a full 180 degrees and I could make it rotate 360 degrees with no apparent stops or indents. In speaking with two different RV owners, one says this is "normal" the other says it sounds like I'm missing a part called a "nose wheel stop." Any feedback would be appreciated.

Default Nose wheel 360

You are missing two cap screw stops.

Check your Service Bulletins at Van's. There is a recent one for the nose stop flange installation.

Curt, leave it alone. It's so much easier to push backwards with the nose wheel trailing.

Just don't start the engine with it backwards, I think the prop may interfere with it. At least it would one time...

Fix it. It is not designed for the stress of a 90 degree pivot.

Default Order the plans!

Hello Curt

I just can highly recommend you to order a planset from Vans for your aircraft, if you do not got them with the plane.

You have to answer yourself many question how should this looking, how is this screwed on, what is this for .... Only the plans will give you the answer how vans thought it should be done!

You are the new owner, you have to inform yourself. Don't be surprised if you find out that something is not made as vans has designed it ... check it carefully if it is just another method or if it is just a dirty fix.

As earlier in this thread mentioned, check all the Service Bulletins for your Aircraft and be sure you comply, just for your own safety. You find the Service Bulletins on Vans homepage.

Vans have the plans also on CD, so you can upload it to your device and you can carry them with you at the hangar without the paper.

All the best and enjoy your RV, it is a wonderful airplane!

Hey Curt,

Here's what it looks like, correctly installed. The Allen cap screws serve as the stops. As referenced by the service bulletin that Bruce posted, they are often installed backward, with the ears pointing aft.

Pierre brings up something I hadn't thought about. The damage from installing the stops incorrectly occur from the forces of the incorrect geometry of the stops. What are the risks of no stops? Lets assume the prop clears the tail end of the wheel pant.

Default Would not recommend

That prop comes really close to the wheel pants if not actually hitting it. If you are not paying attention like at a quick fuel stop and then pushing back to get out of someone's way the damage could happen very fast. And be expensive.

It's amazing how distractions can happen when least expected.
