I pay good money for taxes to the Feds, I am calling the FSDO Monday and let them earn it, and explain!

My PMI is good at figuring this stuff out and has helped in the past when I wanted to do something unusual, maybe he will get this one.

Gonna give it a whirl.

Talked with the FSDO today and they agree if a part is a PMA replacement part then all you need is a log entry no STC, but hold on.

Except I also just talked with the FAA engineer who worked the STC at the Anchorage ACO (Dave Swartz, the one Airframes Inc said to call see page 8 & 9).

He told me the struts are NOT a replacement part and perhaps the PMA should be corrected because it calls them that, they are really modification parts. And he said that the Airframes Inc struts can only be installed with the STC and that requires a 337 and an IA contrary to the Airframes Inc post on page 9.

Drude,
A 337 is used when you make a major alteration or repair to any structure on an a/c. For example, if you weld on STC'd float fittings you have altered the structure of the airframe. Since your simply replacing parts here the 337 is not required. The STC is just there to cover the AD.Hope this clears it up for you.

Levi


So McAnaul's statement about log entry only on page 8 and 9 as well as mine and others are wrong, thru no fault of our own. A 337 is absolutely required with the Airframes Inc struts. What bunch of confusion that starts from the wrong info on the PMA and frankly from Airframe Inc.

So bottom line is if you use Airframe Inc's struts you have to do a 337 it is an STC installation. Univair & Taylorcraft wil only need a log entry.


BTY- My FSDO also says they will process AMOCs, I just misunderstood because they sent me directly to the ACO last time. So I was wrong about that. Also FSDO can reject and AMOC but cannot approve only the AD controlling office/manager can approve and also reject.

Re: A list of lift strut suppliers (updated 10 Nov 2007)

Here is the latest from us. Our Designated Engineering Rep (DER) here with the company called me late yesterday afternoon to tell me that the Denver ACO have given us Design Approval on our expanded model applicability for our lift struts. For those who don't speak FAA this means, The Denver Aircraft Certification Office is finished hatching our paperwork. This is where the traditional bottleneck is on any project of ours large or small. Design Approval means that they say that all the boilerplate we sent them looks beautiful and they aren't going to give us any more crap. This now goes to LA to be wrapped up by the main people people pulling on our choke collar, the LA Manufacturing and Inspection District Office (MIDO).

Bottom line: We may have this thing in hand by Christmas.

Read the NPRM and then Vintage Aircraft , Dec 2007, came in mail today. More in the AM nite nite :beerchug:

It was kind of a pissy thing to say, and for those of us in Iowa it was a little offensive. I do not know you from anyone but maybe from now on it would be better to just observe and not comment on this website.

My apologies to the Iowans too.

Update - I called but much later than I planned and now waiting for FAA/PMI to return my call. More later I guess. Dave

Forrest,

Apologies, sorry if that was terse. I am having a very pissy day and it seems to be having an effect.

Ah crow is good, I use tabasco on mine, and NOW the new NPRM on the LIFT Struts is on the Federal Register.
I am on my way to the EAA #82 Christmas Party, I have it as a PDF on the OTHER computer. Ii printed it and will read it tonight. Comments later.

However perhaps our computer guru's can find the link. post it and perhaps start a new Thread on :

ROUND #2. Taylorcraft Lift struts: Comments will be accepted until Jan 9, 2008. This clearly addresses the FAA opinion ( rule, decree, whatever)on the Univair struts. The Airframe struts are not mentioned , guess the old AMOC needs to be done or updated.

Re: A list of lift strut suppliers (updated 10 Nov 2007)

In some previous postings I have addressed this subject, but since folks are coming and going they may not be aware of this situation: Mike Burnett also asked me the following: “Univair's (struts) can only be used on BC12-D/D1 and BCS12-D/D1 aircraft. This leaves out the A-643, A-699, A-700, 1A9 folks. That is how the AMOC is written, and surely it is a mistake on the FAA’s part to not allow the struts to be used on all the T-crafts. “

In short, Mike has pointed out that as our struts are presently approved they have a very narrow approval e.g. BC12-D/D1 and BCS12-D/D1. However, that is of our doing from the time when we got our original PMA in 1992. This does represents the bulk of the T-Craft fleet, but it excludes a bunch of other people. He has another model T-Craft and as such is out in the cold as far as buying an approved strut from us.

I have written a few weeks ago that we are in the process of resolving that. We are requesting the FAA to increase our model applicability on our UA-A815 and UA-A854 struts be approved on the A model T-Craft, the entire B series regardless of engine and the entire F series. We have sent about 200 pages of substantiation to tie all of these airplanes to our struts. What is the status?

All of this paperwork is presently at the Denver Aircraft Certification Office (ACO). Once it is churned through there, the Los Angles Manufacturing Inspection District Office (MIDO) gets their chance to pick it over. Once we get it back from the LA MIDO, then we will have to re-submit it to Mr. McAnaul in Ft. Worth for a revised AMOC.

So welcome to our world of FAA paperwork. When will all of this be done? Once things get out of the Denver ACO, things should move rather quickly. Hopefully by the end of January we should have this thing wrapped up.

OK T-Craft guys Mr. Know-It-All is going to have to eat some crow about how much he knows, but with enough ketchup I have become accustomed to the taste. Thanks to Mike Burnett he prompted me to research something this morning that doesn’t really change the world too much but I have been guilty of perpetuating some bogus information so here goes.

Mike wanted to know where it says exactly that the new sealed struts have to be 4130. There isn’t anyplace. There is no requirement the new struts have to be fabricated from 4130 steel. The AD does require one to get MA-A815 and MA-A854 or EQUALVALENT struts to terminate the requirements of the AD. It just so happens that these parts will be made from 4130 steel.

OK then what is the Univair AMOC (Alternate Means of Compliance) all about. Way back in 1992 when we first got our FAA-PMA approval for our Taylorcraft lift struts, our UA-A815 and UA-A854 struts were replacements for original T-Craft parts A-A815 and A-A854. In the FAA world one cannot assume that the original Taylorcraft or Univair parts are the same as the “MA’d” part numbered parts that the new Taylorcraft factory is going to produce.

Some have wondered why a PMA approved part would even need an AMOC. Good question! We had to prove to the FAA that our parts were EQUAVALENT and sufficient to terminate the requirements of AD2007-16-14. Having done so, we received our AMOC. This is what establishes that equivalency. Some have wondered why a PMA approved part would

Mike also stated this: Unfortunately, the AMOC has a stipulation: Univair's can only be used on BC12-D/D1 and BCS12-D/D1 aircraft. This leaves out the A-643, A-699, A-700, 1A9 folks. That is how the AMOC is written, and surely it is a mistake on the FAA’s part to not allow the struts to be used on all the T-crafts.

I will treat this as a separate subject in another posting.

David , terse? Never without guys like you I would never learn a darn thing....somehow today while playing with my Daughters ( Laura) new Toshiba lap top I got onto the forumn and tried to catch up 3 pages of stuff.

Somehow on this thread the last read for me must have been page 6-9 not the last one, somebody had just used a lot of @#$%^&* cuss stuff and I checked his profile and found him to be a A&P ; thus the response way out of order. ( I could not go back and find him, who cares , nobody uses their true name anyhow)
I have now read the complete thread; a bit of confusion I would say. My newsletter will explain from beginning to end this AD & SB stuff; however just as I think I get a handle on it in the newsletter ;m THEN boom another voice is heard out in the wilderness. Pissy days are cured by Wings & Beer and away I go for a while. Love u all!!:joy:

Re: A list of lift strut suppliers (updated 10 Nov 2007)

Forrest, Maybe you should quote the post so that we don't have to guess who you are talking about. Every A&P on here is now wondering including me. If you have something to say, say it to the one you intend to say to.

Forest,
I got me a new Dell lap top that I just love. I decided to take a break ifrom searching for dead ancestors to see what is going on in the airplane world. It is a nasty habit I developed tagging along with my dad who logged over 20,000 hours before the flight doc said your flying days are over.

I saw where some of you T-Craft guys were at risk of busting your next physical, so I felt for the health and well being of you guys it was time to try and still the waters.
