| Subject: | Starting to Build Again |
A few years ago I started building a 601XL from plans only. I have the entire
tail section complete and both wings close to completion. Just as I got to that
point, I got an email from Aircraft Spruce that they had sent me a batch of
solid rivets that were too soft and I would need to remove all of those from
my wing spars and replace them. I was disgusted. I kind of took a break from
building for a while...and during that time, I changed jobs, changed locations,
went through a divorce...etc. I haven't keep up with with the happenings in
the "601XL world" for a while. Lately, I've set my shop back up, took inventory
of all of the parts that I have and I am pleasantly surprised of the amount
of parts that I have... at any rate, I want to start building again.
I've been reading of the problems with the wings causing crashes and how ZenAir
has an upgrade kit to cure that problem. With me building with plans only, and
my wings not complete yet, now would be the perfect time to implement that
upgrade. Can I get drawings from Zenith to build that upgrade kit?
I'm just trying to get caught back up in any pertinent knowledge before I start
cutting aluminum and driving rivets... For all I know, the 601XL may be grounded
for life and I may need to just drop this project...I just don't know.
Any tips anyone can give me I will appreciate.
Thanks in advance,
Randy

Randy, well come back into the "game"
I presume ZAC will provide the drawings.
One thing you might want to do is to watch the videos they posted on
zenith.aero, showing the upgrade, step by step.
Good luck
Carlos

Hi, Randy
The 601XL is no longer grounded if the modification is done. The plane has
been tested and retested (including involvement by the FAA) because of
suspected problems and is the most examined LSA in the industry. The
modification has resulted in a very strong, overbuilt LSA. Any problem(s)
have been eliminated. You can find much information about what happened on
the internet. bb

1st, I second Carlos' welcome back.
Yes, you are correct that Zenair is not only selling an upgrade kit, but
complete drawings for the upgrade are available for free. I can't think
of any parts of the upgrade kit that would be a problem for a scratch
builder. Zenair have also changed their web support a bunch, setting up
the Zenith Aero site. However, the upgrade drawings are available at the
standard zenithair.com website. You just log on to the builders area,
click on the 650/601XL page, and then links to the upgrade drawings will
appear.
The good news is that there has not been a single wing failure since the
FAA issued their upgrade order for the design. Note that the upgrade was
not specifically required for experimental 601XL's/650's that had their
final registration certificates, but it was highly recommended. I
suspect that compliance is near 100%, but that is just a guess and I've
not seen any hard data. The upgrade was required prior to registration
for all 601XL's/650's that had not yet been approved.
Good luck with your build. Support is available through the Matronics
Groups and through Zenith Aero.

Thank you Terry!
I have lost my login for the Zenith site and waiting for them to send me a new
one... I figured the drawings would be in the builder's area...
I see that in your signature that you are working on your wings too, and adding
the upgrade... I guess, like me, it seems only logical if you are in the middle
of the build to go ahead and do it then.
BTW, since you are just now on the wings, are you going to use the cable system
or the push/pull rods for the ailerons?

BTW the cost of the upgrade is (was?) so cheap that even a scratch builder
should consider just buying it. Zenith is basically selling it for the cost
of materials as it is in their best interest to get every XL upgraded.
