I did not read anything that says the 601 or 650 is grounded by the  FAA?  Anyone else read something different, other than a title to a post  that is inaccurate.  

  

 I will sign my name to my post!

They didn't quite ground it. They "strongly recommended" that the aircraft

not be flown again until the necessary modifications are made.



AMD has not issued the safety bulletin yet. Since there is no safety

bulletin yet, it's still legal to fly the SLSA version.



I'm told that it's been in development for a while, but know nothing about

it. I'll be calling the factory Monday to get the scoop.

Larry,



No reason to get o defensive. Sorry for not signing my name. It;s Hans van Riet. And the way I read the FAA bulletin, it is grounded. It strongly recommends to comply with the mods. And it further states that you can't fly if you know that your aircraft is not airworthy. But to each his own interpretation.

Hi Larry,



 I read the SAIB as saying the fleet is either grounded (S-LSA) or should be grounded by owners/operators of E-LSA and E-AB planes.



 The language is not quite as clear as normal humans would prefer.  I think the reason is to really "Ground" the planes the FAA would have to go through a year long (or longer) process of NPRM and public comments before actually issuing a rule.  This language is about as strong as they could use.  Instead of saying it is against the law to fly the planes, they imply that any pilot who flies one of these planes is in violation of FARs.



 I think it is very significant that they include 650s along with 601XLs in the SAIB.  That means all the effort by the various companies to make the problem go away by changing the model number amounted to nothing.



 Apparently this has been in the works and the release date was influenced by the accident in Arkansas.  I am sorry it took another fatal accident to get this moving, but I am glad the fixes for the design problems are now to be made available to us all.



 I presume the companies, AMD and ZAC, will make the design changes available soon.

The SAIB says that FAA "strongly recommends" the fleet be grounded. However,

it does not say the fleet *is* grounded.



I expect that AMD will issue a mandatory safety letter first thing Monday

morning grounding the SLSA fleet. That has the legal force of an AD. The FAA

cannot issue ADs against SLSAs, according to the folks from the LSA group I

asked at Oshkosh.



However, SLSAs may be legally flown until that happens. This is not just of

academic interest to me: I had a trip planned for tomorrow. As it happens,

it got called off for other reasons.

I hope so. The question I have for you, Paul, is: Will you accept the changes

as AMD issues them, or will you insist that they include other changes if

you don't think they addressed the issues?

Hi Jay,



I can't answer your question until I actually see the 

changes.  However, I believe I will implement at least some of the 

changes and then proceed to have my plane inspected and  into phase 1 testing.



My position has always been (since the NTSB letter) that I wanted 

official changes for the aileron mass balance and control sensitivity 

issues.  I am not particularly concerned with the airspeed 

indication, but I will seriously consider any proposed change 

there.  I think it is safe to assume I will consider any wing 

structure change as satisfying my desire for aileron balancing.  The 

desire was based on the NTSB letter and there is now new official 

information to consider.



I am hopeful I will have my XL in the air and maybe completely 

through phase I before I return my leased plane to its owner next May.

These are things I know as fact: 

- Zenair had designed, and AMD has been working on the steps it takes to

make the mods - and documenting the practical aspects of making the

modifications. 

- This announcement had been planned to be made by the end of October (and

the FAA has had the documents for a few weeks). Issuing the Safety

Alert/Directive required coordination with the FAA. This was finalized only

in the very recent past. I was told there had been some back-and-forth on

whether unmodified aircraft could continue to be flown at the reduced

performance/weight numbers; with modified aircraft able to move back to the

greater (previous) performance/weight. Apparently, that is not in the cards.

- Kits are being put together now for distribution.



Here's what I don't know: any particulars beyond the spar modifications. I

don't believe the items will match up 1-to-1 with the LAA. The facts suggest

that the real engineering analysis - with real data - has been performed by

the manufacturer and the FAA. Those modifications will be the appropriate

set; not the LAA's, as well-meaning as they are.



With respect to a grounding, the FAA can make a strong recommendation - or

order an emergency grounding; but it's the manufacturer who actually issues

the Safety Alert/Directive, and to which SLSAs must comply. That is what the

FAA bulletin reminds us. Jay is correct. Once (and if) AMD issues a "perform

before next flight" notification (which is what is coming it seems), then

one will need to apply for a Special Flight Permit if one wants to move the

aircraft to a place different from where it is currently located to have the

modifications made.



Let's please try to move past this.

The FAA may be able to ground 601s with S-LSA certificates but they  

have no authority to ground all E-AB 601s because there is no type  

certificate to take action against. The FAA would have to ground each  

individual E-AB on a case by case basis since each one is considered a  

one of a kind airplane. Besides which, during phase 1 testing I have  

flown my airplane to 4 Gs at a gross weight of 1320 lbs and have flown  

it to 110% of my stated Vne. I have carefully and systematically test  

flown my plane to the limits of its documented flight envelope and am  

confident that it is airworthy if flown within that envelope. I see no  

reason to reduce my flight envelope. I am the manufacturer, it is my  

decision to make, no one else's.

Late breaking news: AMD just issued a Safety Alert, this evening, grounding

all 601XLs and 650 SLSAs. Zenair is with the FAA and the NTSB at the

accident site.

Can these drawings be viewed anywhere???      Complete the upgrade by using the following information:

i. Drawing 6-ZU-1, 6-ZU-2, 6-ZU-3, and 6-ZU-4.

ii. Photo guide with construction standards

iii. Use “FAA AC-43.13.-1B and 2A if additional information is required

iv. Use the UK LAA's modification MOD/162B/004 dated 18/08/09 for only

the installation of the aileron counter balance weights. Drawings and

assembly instructions are part of the modification       Cheers

Questions For Discussion



1. The FAA is saying that the E-AB guys should use the AMD fixes How will we get these drawings and parts?/ I am not a customer of AMD  I bought a kit from the boys in Mexico MO. Anybody on the list have any contact with the Zenith in Mexico MO??  I'm assuming they are doing the changes for AMD and are the ones really doing the drawings and making the parts?? 



2. The AMD Letter refers to the EU/UK LAA mass balance weights drawings and I've read that. However, the LAA doc also calls for a carry through spar mod that AMD makes no mention of.  SOOOOOO are we gonna have to do the carry through mod or not???



3. The AMD docs say the plane should be placarded per the November 2009 bulletin.  So how do the E-AB guys get that bulletin?



What a mess  I think its poor planning and PR and engineering practice to point to a EU / UK LAA document that is not drawn and managed by the designer / manufacturer, and not at least discuss WHY you are NOT saying we should do everything in this document but only do part of it.



Zenith /AMD  may not feel the spar mod is needed but at least say that or SAY SOMETHING!   To be mute on the issue is NOT ACCEPTABLE!!



I'm ready, willing and able to do any mod to my nearly complete 601XL  but I want words from Zenith as to their reasoning behind only implementing part of the LAA letter and not all of it



Zenith     NOW IS THE TIME TO SPEAK UP!!!  Every day you waste not addressing these questions devalues my aircraft, your investment in the 601 / 650 program and the Zenith Aircraft company.



I believe that no matter what problems may exists with the 601 /650 they are all fixable and we can have a safe respected airplane, but that requires the factory and designer to step up and say something

Hi Larry,



I think a little more patience will be rewarded.  My take on this whole mess:



1.  The FAA and AMD releases were rushed by the Agnos, AR 

accident.  They probably planned to all make the announcement at the 

same time to prevent the kind of frustration you are experiencing.  I 

think ZAC will make a similar release soon - Probably Monday morning.



2.  The AMD planes are more similar to each other than kit built 

planes.  That means some of the details for AMD owners are easier to 

spell out than they will be for kit builders or plans builders.  This 

especially applies to things like POH which will be different for 

each kit built plane but all the AMD planes probably use the same one.



3.  Chris Heintz has apparently been deeply involved in the 

development of these changes.  He has already announced (I think) 

that the LAA changes don't meet his approval.  I think we can expect 

a similar set of changes released from ZAC as the AMD ones but with 

orientation towards plans and kit builders rather than S-LSA 

purchasers.  The design is the same, but the freedom to make changes 

doesn't exist in the S-LSA world.  Also, AMD is calling for A&P 

efforts to make the changes while experimental plane owners will 

mostly work from plans or parts supplied by ZAC (or Aircraft Spruce) 

to do the changes themselves.



I am full of hope now that my plane will be able to fly pretty 

soon.  The changes are pretty extensive (at least according to the 

comments on AMD and FAA releases) so it might take a few months to 

complete them.  Still, I have never had a completion schedule and I don't now.

Comments inline to Larry Whitlow's questions. I can partially answer some of

it. Please note that I have no connection with Zenair, Zenith, nor AMD. I am

an AMD customer. What I'm sharing is what I've been told.

Hi Jay,



After further reading and thinking over the situation I would like to 

add to my previous comments on your question.



I am delighted that Chris made the personal effort to come up with 

the change package.  My biggest concern with any changes was that 

they might have negative impacts on the rest of the airframe 

design.  I decided I wanted someone with design responsibility to 

review the changes and offer the opinion that the changes would at 

least not reduce the overall design safety.  To have Chirs himself do 

this is a bonus in my opinion.  He is retired, but apparently he 

hasn't given up personal responsibility for this design.



Part of my own thoughts over the last few months has been what to do 

in the event that my Zodiac was still grounded when my lease on the 

Tecnam runs out next Spring.  The most important idea I had was 

this:  The difference between having a plane to fly and no plane to 

fly is much greater than the difference between having one model 

plane vs. another model.  I submit this is a good way for those who 

are worried about possible performance or handling changes in the 

Zodiacs to consider when the new design improvements are installed in 

their planes.



With the FAA, EAA, Chris Heintz, and probably Santa Claus urging all 

owners to install the design changes, I hope everyone will do 

this.  For my money, the improvement in safety is much more important 

than a possible reduction of a knot or two in speed or a few pounds 

of useful load.



To those owners who are just now discovering that owning an airplane 

includes unexpected expenses I offer my sympathy.  In truth this 

applies to all airplanes.



I remember someone commenting a few months ago about "The horse that 

can't be rode".  Hopefully these changes will transform the Zodiac XL 

(and its twin the 650) into the well behaved design we all wanted 

when we chose it.

I have to agree with you and Doug, that, once you have the airworthiness 

certificate, you, the manufacturer and pilot of an E-AB, are the judge of 

whether or not your creation is airworthy. But I would like to add a bit 

more information for you to consider. With Mat's permission, I am posting 

the following message that I received this morning. I hope that all owners 

of E-AB 601XL's and 650's will consider what Mat has to say, particularly 

in the 3rd and 4th paragraphs.

<snip>

Supplying them at materials cost is a step in the right direction. It's 

necessary, but whether or not it is acceptable remains to be seen. 

Meanwhile, I've been looking at the draft drawings to see just how much it 

would cost me for raw stock to get on with this show. I'm reluctant to jump 

in to some of thease changes, because I suspect some fine tuning remains to 

be done. However, so far, it looks like I could do this for a heck of a lot 

less than $1,000. I also might be able to avoid waiting for the upgrade parts 

to be available.

I have run into a snag: finding .093 3/4 x 3/4 6061-T6 for the spar uprights, 

and 1/8x1x1-1/2 for the front wing uprights and wing extrusion angle. There 

are some other snags, but those are things that I won't be doing for a while.

I've looked at ACS, Wicks, Airparts, and a few others with no luck. Has anyone 

else found a potential source for these materials?
