Fuselage strut fitting - FAA Airworthiness Concern Sheet (merged)

Re: Fuselage strut fitting - FAA Airworthiness Concern Sheet (merged)

The fairing is cosmetic and makes it real easy to look again once in a while. The cutting away of the fabric insures that it is not "tucked up " into then fitting like a wedgee.... that is another phonetic spelling ; GOT it Darryl, I had not remembered that word!

Is thie strut fairing fitting something we can fabricate? Is there a picture of the fairing?

I have left mine in that cut away condition for about 25 years. I doubt it slows the plane down much and it does keep it dry an visible.

I cut the required clearance in the fabric and added the reenforcement patch did some borscope checking. I intend to do more when the struts are removed this week. I also made a mirror which works pretty good except for the center section when the struts are in place... The front struts from Univair are about 1/4 inch larger than the original struts on my plane...The attachment so far looks great..see attached pictures

The center section was the object of a lot of discussion that is the part the NTSB wants to have inspected completely. Many phone calls on that one. Plus we tried digital radiography too.
All this is Operator ( read as technician, A&P, IA, repair station, etc.) knowledgeable opinion , I know a lot of us know WHAT to look for but how to put it into the form of wording was the problem.
THEN we see the revised AD on the struts with a lot of FAA legal jargon now included.

Re: Fuselage strut fitting - FAA Airworthiness Concern Sheet (merged)

Has anyone tried to fabricate an aluminum cover, instead of patching the fabric after complying with the SB on the strut attach fitting? I know this will detract from the originality of the aircraft, but I just hate seeing fabric patches on a fabric airplane. I would rather see an inspection cover than a patch. On my vertical stab there is a large square hole with this plastic glued around the edge. An aluminum plate is attached using PK screws that go into the plastic.

Does anyone see anything wrong with doing something similar around the strut attach fitting? You could use two pieces of aluminum, one on the side and one on the bottom of the fuselage. They could overlap just in front of and behind the actual fitting and be secured to the plastic in the edge and to each other with small screws.

Once again, I am fully aware that this masacres the original appearance. But from a practical standpoint, until we know for sure if this is going to be a recurring inspection, this is a way for us to comply with the SB and not have our aircraft look like a patched up crate. Then when we recover, hopefully after we know the final outcome of this mess, we can return the plane to it's original beauty.

Opinions, suggestions, comments???

David Whitaker and Dad Lou did just that I have one here for mine. Will try to get David to re post. They are .032 aluminum and look real nice. off to a party now, will at least scan tomorrow.

Tribe, yes I made a fairing for the strut attach point. Dad made a drawing that can be used as a full size template to make a set. I will get down to the airport over the next couple of days and shoot some pics and post the drawing.

Hey Forrest, saw the posting about the strut inspection plans, sounds good. Will call you later to get the date and time.

Re: Fuselage strut fitting - FAA Airworthiness Concern Sheet (merged)

If all goes well, this attachment should be a word document you can print out and use as a full size template to make a removable inspection plate. A couple of tips: I used a small nail and heated it to put the hole in the fabric for the screw. Also, two sided tape on the backing plate holds it in place so it stays put when you remove the screw holding the cover on.

The Elves were busy during the night!! Thanks David , I ran into your Dad at Lowe's last night ( we were getting Lowe's PMA parts) .
He mentioned that you were having him redraw the plate for posting. GOOD WORK! THIS time I will save it correctly.

I still bet that is .032 aluminum not .031 , (

Hey Rob or any other computer guru out there - I tried to upload a picture of my inspection cover but I keep getting an error message.

This is not a valid image file

Any ideas? I am lost.

Re: Fuselage strut fitting - FAA Airworthiness Concern Sheet (merged)

Don't know, Dave, email it to me a robert dot lees at taylorcraft.org.uk and I'll have a look.

Merry Christmas!

Re: Fuselage strut fitting - FAA Airworthiness Concern Sheet (merged)

I get the same, Dave. I'm not at home at the moment; I'll need to get to an image editing suite before I can upload it.

Yes Forrest, Home Depot Aircraft and Supply Company sells the blank stock to make the owner produced fuselage strut attach fitting inspection plate. It is indeed .032"

Re: Fuselage strut fitting - FAA Airworthiness Concern Sheet (merged)

It worked for me
