46 BC12D wings on a 41 BC12?

[t30mg]

Does anyone know if the 46 wings will fit on a 41?

I have found a set of wings for reasonable and it seems it would be more economical and faster to go this route rather than fix up my damaged wings, if it will work....

Should work OK.

If the 41 is ATC 696 , just do it.... ; only thoughts are "revised aileron travel" .

check the ATC 696 :

Model BC12-D, 2 PCLM, Approved November 23, 1945; Model BCS-12D, 2 PCSM, Approved February 19, 1946
(Same as Model BC12-65 except for alternate tail surface, revised aileron travel, alternate one piece windshield and other
miscellaneous structural and non-structural changes).

There may be a good market for the parts from your pre-war wings, even if pretty badly banged up. The pieces of the ribs are even valuable to use to splice repair other ribs. You also may want to check the aileron brackets. Pre-war they were weldments from steel tube. Post war they were Magnesium castings and tended to crack. I am pretty sure you can use the welded brackets on a post war wing. They are certainly stronger and more reliable.

Correct on all counts.

Discussing wings, I am still looking for a left BC12D wing. I have started taking my damaged one apart to repace the rear spar, but it is going to take a lot of time. I would sure like a copy of the wing drawing to make sure I get every thing right.
I have lots of parts from a damaged F-19 but the rear spars in both wings were broken. I have that left wing apart and the front spar appears to be good if anyone needs one it could be available for trade or at a reasonable price.
Quite a few other F-19 parts too, but a lot was damaged.

Forrest said a few weeks ago the CD of drawings would be avialble soon. He said to watch for the announcement in the next news letter.

I previewed the stuff on CD this weeik ; going on www.warbirdradio.com this morning ; sold two Tcrafts , bought two more ; we have two Model D projects here now. Still looking for volunteers to come help with the drawings and computer stuff. Lots of members just show up and buy parts & copies of stuff , I cater to them first at that visit of course.
Real sorry about delay.

What is the difference between pre- and post-war wings? We have a 1941 BC12-65, but suspect that the wings are post-war. Two differentiating factors that have been described on the forum are in regard to the type of ribs—I believe the pre-war type were referred to as “built-up”, the post-war being “stamped”—and the aileron brackets—pre-war “weldments from steel tube”, post-war “magnesium castings”. I also recall something about the number of ribs possibly being different.

See the attached photos of my wing. I would assume that our ribs are stamped, but since I’m a rookie, need to ask to be sure. I don’t have a good picture of the aileron brackets but they are definitely not made from steel tube.

What are opinions as to the vintage of our wings?

Your wings are definitely post-war. All pre-war (and some early post-war) wings were built-up, or "truss" wings.

I also used to own a 1941 BC12-65. Built in 1941, its completion (and further production of civil Taylorcraft) was stopped on 7 December that year.

After the war, when civil production was resumed, it was completed with a set of 15-rib built-up rib wings, and certified as a BC12D. Still the lightest Taylorcraft I've flown.

If it helps, count your ribs...a dollar to a pinch of elephant dung that you have 15 ribs (which should have the comensurate 1200lb gross weight to go with it). But your data plate may say otherwise.

Re: 46 BC12D wings on a 41 BC12?

The first and last ribs are different than the rest in that they have a doubled vertical section. Including these ribs there are 15. Does that mean I don’t have to go out and find elephant dung? I sure hope so!

Our plane has a 1200 lb gross weight. What are the otherwise possibilities?

13 ribs (only ever the truss type) were 1150lb gross, but this only applies to the early B models.

Re: 46 BC12D wings on a 41 BC12?

Hello guys:
The build-up ribs are fully interchangeable with stamped ribs, in the 15 ribs wings, and very possible also in the 13 rib.
So, can be a B12-65 with all ribs stamped, and is legal, I believe from here, far of USA.-
Best regards,
Miguel.-

You bet the built up ribs have a value. I need several! Let me know if you end up parting those wings out. Larry
