May also be worthwhile to know where people are mounting heavy items, like BRS
& batteries.

| Subject: | Ground vibration testing |
According to an article in the latest Kitplanes, the German government
requires ground vibration testing (GVT) before they will approve flight of
kits built in aircraft in Germany.
Assuming this to be true, it would suggest that the Czech version of the 601
has had GVT done. Does anyone know it this might also have been performed on
the US version?
My interest stems from resonance being a possible reason for flutter and other
failure modes. It does not sound as though Zenith has done GVT here. In
fairness, GVT may be impacted by differences in the specifics of changes in
different aircraft. However, it might be worthwhile to know if the basic
aircraft has any problems in this area.

Front fraking right?!?!
I'd hate to be in the right seat if you ever had to deploy the chute.

While it would be interesting to know what you are asking please keep in mind that
the Yuba City report pretty much ruled out flutter in that accident.

True. But we may have more than one thing happening to cause accidents. I
still wonder about maintenance of some of the aircraft.
I have a lot of questions .... and very few answers. The Yuba City report
seems to say the aircraft came apart in the air for reasons other than
flutter, yet does not really establish what those reasons are.
That may suggest the reasons are subtile, and not easily determined.

It has already been tested and (as I recall) the pilot and passenger walked
away. Picture attached. Was it Poland or the Czech Republic?

I think it may have been housed just aft of the firewall on the right side. A
recent post by Mathieu Heintz indicated that they were putting it there on European
XLs. The photo seems to show some rumpled skin in that area.

We may...no strike that...We probably won't ever ever know what happens right before
the wings come off unless somebody just happens to have their EFIS recording
data or a camera running in the cockpit when an accident happens.
There is another scenario where we could find out what happens. A pilot with a
BRS. The problem with even that is that the pilot in question would have every
reason in the world to lie if they had been doing something that rips the wings
off.
The Yuba City report goes out of its way to NOT rule out the aircraft was over
stressed. There are several ways that can happen and not all of them are the pilots
fault. That's what I always thought it was and no supportable data has ever
been released that counters that position. Is the 601XL as strong as Cessna
172? No but neither is a motorcycle as strong as a Hummer.

Well they talk funny there too.
That is amazing. I can't put a screw in the canopy without causing a crack yet
this one can have a rocket go off inches away and not damage it.
Look at the gear on that thing. It pulled MANY G's on impact and yet the wings
stayed on.
