Frank,
If you want to subscribe to ZBAG you are Welcome. Regarding PH or Hingeless wev´ve discussed that on ZBAG and there are a 50-50% of accidents so PH or not is not relevant.
One comment, our XL would be the most tested home built plane in the sky when all the nightmare ends. So be optimistic.

I completely agree with you, Alberto! After the necessary tests are performed and a fix is available (something similar to what UK LAA is testing at the moment), the airplane will be one of the most thoroughly tested LSA/homebuilt planes. That gives some confidence!
However I am not completely sure of what a (possible) US grounding would/will trigger. So far the response by Zenair is poor and they seem to assume that all XL-accidents were due to pilot-error, possible sub-standard material or improper maintenance of the aircraft. Zenair Europe committed to conduct different tests (including a GVT and load tests) for the german authorities by the end of March - nevertheless there are no test results available by now. In addition I (and I believe others) did not get an answer by Zenair to our email why the German tests were not extended to meet LSA weight standard.
I hope that the current NTSB recommendation will change Zenair's mind regarding the importance of forthright, uncensored communication and immediate and through testing of the 601 XL!
I continue working on my 601XL project as I am still (and even more now) confident that Zenair is assuming their responsibilty! ZBAG has given lots of input to the NTSB (that's why IMHO the NTSB paper is of such good quality!) and I am sure ZBAG could/should support Zenair in doing the tests. I hope that Zenair is taking this opportunity and finally starts working constructively together with ZBAG!

Hi Frank,
I spent a few years in the gumint business myself. I agree with all you said and have grounded my plane without waiting for the FAA bureaucrats to make up their "Minds".
I'm no expert on pickling engines, but the impression I got is all you really need to do is spray some special goop into each cylinder to prevent corrosion. When you are ready to use the engine again, just blow the goop out by removing a spark plug in each cylinder and cranking the engine a few times around. I suspect you can find the special goop at any aviation oil distributor.

- We ..as a group of owners and builders.. should forget about nit-picking, carping, and whining and focus like a laser beam on how to get mass-balanced ailerons on our birds ASAP.
- Hingeless ailerons? I'm not qualified to comment technically, but bureaucratically, asking the FAA/NTSB to contemplate hingeless ailerons is like asking them to contemplate the impact of angels on the economy. They won't know what to say.
- I'm joining ZBAG immediately. That group has done good work and I should have joined sooner. Being cheap was being stupid.
- I'm reading up on how to "pickle" an engine
- I'm calling my insurance company and telling them the airplane is grounded.
- We can't say we didn't see this coming.
- I'm grounded and unhappy, but I think the NTSB did a good piece of work. We have to get those hingeless ailerons flying.
