PA-12 Cabane Vee Questions..

[daedgerton]

Repairing the 12 after the ground loop... My 12 has the 18 gear STC SA669AL (Crosswinds). Ordered a cabane from FA Dodge and when to check fit and it was too short. Turns out the distance between the cabane attach points is 27 11/16 inches vs. the 25 7/8 as called for in the STC and how FA Dodge builds their cabanes...

Any thoughts? Cliff from FA Dodge has been very helpful. They are going to build me a custom one to fit. Was my fuselage widened? He mentioned that some 12's were not built in Lock Haven and had slight differences..

See pictures below:

Depends on who manufactured the weld on fittings and how they got welded on. Usually you use the cabine v as a jig to make sure everything is straight when welding. Atlee sells the tabs and everything fit perfect on mine. I wonder if your original cabine is for a PA-14 with 3” extended gear? That might explain the width problem. Ask Cliff to measure one for a -14 with extended gear.

Not uncommon. At least not in my life. Dakota Airframes' PMA fuselages didn't fit Atlee's cabanes.

FYI.....-12 and -14 are same width down there.

Cliff is a wealth of knowledge however you slice it, tho. ........and happens to own a -12

Yes, he has been very helpful. Our tail numbers are fairly close as well...

On another note... if you run 3 in extended gear do you need a modified cabane?

Cabanes the same. Lower leg length are different for 3" gear. If you go with an AOSS, you should measure everything up and Burl will make sure it all works right with the cabane you have.

Not much interchangeable on pa-12 each one is unique

Have you talked to Charlie at Crosswind STOL? Wondered if he might know why the difference.

I am in the middle of changing my PA-12 to a PA-18 gear and have run into the same problem I had bought the cabane from Atlee and its to short to install I am going to call Atlee Dodge on Monday and see about solving this problem. My -12 serial number is 12-1866

Atlee has been super helpful so far. My custom vee is currently under construction.

My son and I just just finished a 12 with the last Dakota airframe he built and took 6 in gear and cabane of old frame that had cub gear stc and fit right on new frame . I will measure width

Yes, I did speak with him. He said that the standard width is 25 7/8 per the SA669AL drawing. I pulled out the drawing (pictured above) and yes, the drawing states 25 7/8 but the tape measure doesn't lie!

Could it be as simple as you ordering a cabane V for a PA-18 instead of for a PA-12 with an -18 gear? The V would be wider for a -12.

Atlee grumbled about my -12 cabane not complying with the STC since that STC was used for my PMA’d replacement airframe. But Atlee grumbled about a lot of things.

 

[stewartb]

An Atlee -12 cabane is marked PA-12. pretty easy to identify.

Lol. And the Pope is mildly catholic!

A friend mentioned that a PA-18 cabane for a 4 inch wider fuselage might fit. I'm just going to go with the one Atlee is making me at 27 11/16. will post pics once I get it....

Nope. it was marked for a 12 and measured 25 7/8 between the bolts...

Another question here regarding adding altee dodge cabane vee fittings to a Pa-12. Is it possible to use stock PA-12 or Pa-14 gear with the fittings installed?

Currently running beefed up PA-12 gear but could see how having these could be handy if going to floats where the cross wires attach via the vee fittings.

 

[flybynite]

Is it possible to use stock PA-12 or Pa-14 gear with the fittings installed?

Yes, but... when the tabs are welded on, the cabane should be in place to assure the bolts and holes all line up. You also have to assure there is clearance for the original gear to fit between the tabs.

 

[kr_cub]

Excellent…that’s is the info I was looking for.

Thanks Kyle

Get the custom cabane vee built. The front landing gear fittings are not located directly under the lower longerons as PA - 12 are supposed to be. That changes the measurement of the cabane vee. I have this same issue on my experimental -12.

 

[buckchop]

I ran into this problem when i rebuilt my pa12 that had 18 gear, the old 12 fuse that got squashed had a 18 gear and cabane V which is narrower than a 12, the holes for mounting the gear legs and cabane to the fuse where farther apart than normal, pretty sure someone made them cabane mounts, and the cabane was modified also, so i had to get an Atlee Dodge cabane and put the replacement 12 fuse in Charly’s jig and Mike did the tig welding work for me.
Also some use pa20 rear gear mounts with pa18 cabane mounts for the front mounts, i think there is also the mount with both sets of holes for gear and cabane.
Hope i got that right. Hahahahaaa
