On the one hand, I'm happy that there is a path that will unground 601XLs in
the UK.
On the other, I have the uncomfortable feeling that this may be a little like
trying to swat flying insects: it may not hit the actual problem(s), if any.
We still do not appear to have a firm definition of the actual problem(s).

That is great news. Will there be an XL flying to the Sywell Revival rally?

Hi Jim,
While I believe you are correct, I am afraid this is as good as it
will get. The FAA apparently has decided there really is no problem
with the XL, so we can expect nothing more from them. Chris has
promised release of the design changes when the situation in Europe
reached a conclusion, so I guess we can now get the drawings.
I just wrote an email to Sebastian asking for the drawings. When I
get them, I will probably implement some or all of the changes on my
XL and proceed into flight test. My position since the NTSB letter
was released was that my plane would be grounded until their primary
complaints were resolved - aileron mass balance and a control
improvement to eliminate the response problem.

This is like - A guy comes into the hospital with a sore leg, lacerations and
blurry vision.? Going only by what other people have told him was wrong, they
set and cast his broken leg, clean, suture and bandage his lacerations and remove
the cataracts and insert new lenses.? Only his leg wasn't broken, it was just
sprained.? His lacerations needed only band-aids.? He didn't have cataracts,
and simply needed corrective glasses. The guy goes home satisfied, but later
dies of undiagnosed cancer.? Is this analogous ?

Paul,
The control response "problem", given the posts I've seen, resides in the h
and on the stick. This is a kabuki dance.

...or possibly, by making to corrections to things which may not have been
wrong in the first place, one of the corrections causes new problems.
We really really need to do something to appease people, even if it is wrong.

Exactly.
But, I think this is really the next best thing to finding out the airplane is
bulletproof, no matter what the pilot does to it in flight or in the hangar. (Not
in THIS lifetime!)
We in the US of A have the luxury of implementing some, none, or all of the recommended
"fixes" in our E-AB Zodies.
If the spar stiffening results in a G or two of extra margin, I'll consider that
one. Beyond that, who knows? My personal preference is not to monkey with the
control system, but just maintain cable tensions.
Well, they had to come up with SOMETHING, whether or not a real need was ever proven.
It could've been a lot worse.
