Not what I'm saying! I'm just thinking that if someone took the placard method... which is cheap and expedient and perfectly legal.... there is still nothing on the tail to prevent the rudder from jamming. Aside from a warning not to do intentional spins.
it seems to me that a piece of metal installed there would do a lot more than to prevent any potential jamming than words on a placard in the cabin.
If someone is unwilling to perhaps part with the money, time and inconvenience to get the kit, have it installed and update the logs, what else are they unwilling to do. There's a pattern here. Folks who skimp on something are prone to do the same skimping on other areas.
Believe me... I understand that the placard by itself is perfectly legal. But rather than doing the mnimum, I'd just be more comfortable with something that goes a bit over the minimum.
Do ya want your brain surgury done by a newbie who passed with a 70.0... perfectly legal.... but minimal... or the experienced pro who aced everything? Same analogy.

I'd also be interested to seee the mad dash toward the end of the window to get this done by the procrastinators. And I'll bet that it won't be to install the mod kit.
Again, I want to emphasize I am NOT saying anyone that placards the airplane is skimping. I
am saying the kit installation goes beyond what is minimally required.
