location off rear baggage support

[t-crafter]

Can anyone tell me the exact distance from the seat back cross tube to the rear baggage cross support is? My A model had a different set up which wasn't in it when I got it. I am putting in a regular canvas baggage bag in and need to weld in the 2 support tabs for the spruce cross piece. I think it should be about 16 in. from the top cross tube on the seat back, but not sure.

Re: location off rear baggage support

I think it depends on which configuration you have or are trying to create.

I'm going to use the AS baggage compartment (which by the way is not the exact shape of the baggage opening) and my may 46 BC12D had the tabs welded to the top of the 5/8" O/D vertial/diagonal tube. If you look in the lower left corner of this photo you can see the bracket (I installed two clip nuts)

This is the configuration I ended up with (I was unable to find any photos or drawings of another BC12D with those type of aluminium window frames):

You can see that the opening for the baggage compartment ends up trapezoidal. The fuselage is wider at the seat-back cross-tube compared to the hat shelf cross piece. The AS baggage compartment has equal dimensions front-back. Of course that may have been how it was from the factory too.

Why don't you place it so the center of the sling is at the location that the TCDS says the baggage weight is applied?

Re: location off rear baggage support

That vertical tube was not used on the A model Scott. I have been going over your blog pic. Really nice work !! I think I will wait for my baggage bag to come in and just build off of that. Dave,s got a good idea to research also.

Thanks guys

Carlton,

I have landing gear for an A.

Wouldn't you like a spare?

It needs a cabane but that's an easy fix.

Re: location off rear baggage support

Dad has an A model project. The fuselage is already covered. I am going to visit tomorrow. I'll try and remember to take a look to see if the baggage frame work is there, and how it is done.

Scott, nice work! That's going to end up looking good.

Re: location off rear baggage support

Did the A models even have a baggage sling originally? I have no first-hand knowledge of them, but I'd be surprised if they did...

Re: location off rear baggage support

Thanks Tom for checking on your Dads A/C. The A is a basic aircraft that was built on a tight budget and did not have any frills at all and probably did not have any luggage bag. That is why they where in the low 600# range. This aircraft has a 1 time STC that included a A65, skylight and side windows. I am trying to correct a problem that caused water leakage around both the skylight and side windows as well as staying within the STC ! Paperwork can really kill a good project airplane so give a lot off thought before you go and apply for a any type of a change.

Dave, I sent you a PM on the gear .

Re: location off rear baggage support

According to the TCDS the A model has 30 pound bagage capacity. I did take a look at the fuselage today. No welded tabs. Wood frame, and smaller than the B model bagage. I will post a picture tomorrow when I'm back on my desktop.

Re: location off rear baggage support

Carlton, On the 1939 BC I have uncovered the distance is 11 inches. My flying 1940 BC is 11 inches also. I know nothing about the A models, however there is a very nice one thirty mile west of me at Lepsic, Ohio that supposedly is all original. Was restored years ago and kept at Ruie airport at Lepsic.

Edit> I see you got your measurements.

Re: location off rear baggage support

Here is a snippet from the TCDS;


AIRCRAFT SPECIFICATION NO. A-643

Type Certificate Holder: Taylorcraft, Inc.
Connellsville Airport
Connellsville, Pennsylvania 15425

Maximum baggage 30 lb. (+41)


Datum Landing edge of wing.


So here is part of your answer.

The baggage sling must be centered at 41 inches aft of the leading edge or your airplane does not conform its type certificate. That is not the end of the world.

You could make it a non conforming airplane but you would do it by making an alteration and recording the new location of the baggage sling center.

There is a much easier approach in my opinion.

Level the airplane by leveling the horz. stab.

Measure in a direction that is parallel to the horizontal stabilizer (ie level) 41" rearward from the leading edge.

Mark it in some way.

That mark is where the center line of your sling will be.

Then measure from that mark (again parallel to horz. stab.) to the seat back. Double that distance and you get the distance that the aft sling support is from the seat back (also known as the width of the baggage sling).

I don't see anywhere in this TCDS where it specifies leveling for the method of measuring or the horz. stab. as the reference surface but it is that way on B models so I assume it is on A's. Someone else may know more about this.

Dave R

p.s. the distance from datum to baggage is 40" for all the B's - TCDS A696, TCDS A699, TCDS A700, and all models A and B have datum to seat as 23"

Re: location off rear baggage support

Thanks guys, I have enough info now to find my rear bracket mounting point. This A/C was a little nose heavy with the A65 conversion was done in 1995 so adding a little weight behind the datum line would be a plus.

Thanks again
