My RV has a heavy Hartzell CS prop and with just me and full fuel the CG is at the forward limit. RV6 has a small tail. The farm strip is bare earth and I nearly always have a look at the touch down marks after landing. Always land with the stick well or fully back however the nose will always touch within 5 metres of the mains. Cant keep it off and I don't try to when taking off, I like a positive rotation at the correct speed, departure stalls suck big time.
The nose leg on the RV is plenty strong enough, it is the same type as the other legs on nosewheel and tail wheel RVs. If it can support the weight in the hangar it can support the weight going 50-60knots down the runway.
So why do they bend?
I think it may be some form of violent shimmy. We have a long spring with a heavy piece (nosewheel, fork and spat) on the end. Imagine the aircraft lands in a crab or the free castoring nose wheel is at a slight angle at touch down, it flicks to one side and then on the next touch it binds slightly and drives the nose leg sideways, repeat a few times and the leg bends.
A few years ago there was one at Narromine with the leg bent out the side, it got me thinking why is it so.
The one at William Creek had an after market reinforcement, it did not say what type in the ATSB report.
What can we do.
Correct nosewheel tyre pressure, Van's recommended 25-35, they say less is better, I use 25psi.
Correct breakout force on the nose leg, 10kg for my aircraft.
No side slips on final, we want that free castoring tyre to be straight at touch down.
Land it like you are doing a wheel landing in a tail wheel aircraft, smooth, straight, no crab touch and a slight pin, we don't want that free castoring nose wheel skipping about.
