Re: Wing Strut attach fitting A-A11 Inspection results

Mike,

Mine doesn't have a tube, either. As far as I know there is no tube in there-- are you going by the picture with the bolt running through the fitting? Could that be what you're seeing as a tube, or does the one you've got have a tube there?

Seems like if there was anything there except for a bolt and the strap around the outside of the fitting, you'd have a hard time getting behind it to remove any corrosion.

Congrats on landing the ship with the broken prop! That's some skillful aviating.

Re: Wing Strut attach fitting A-A11 Inspection results

First time writting to the site, have a question. But first let me say it is fun and informative to see what you all write about all the subjects. I have a 1946 BC12D that I rebuilt after my wooden prop came apart at 2000 feet above a small town here in NE Tennessee. A whole lot of shaking and an uneventful landing in a field. Wing rebuild, rotten spars, and a new paint job plus a little more and it flew again. I did the inspection on the attachment points and it looks real good, passed. Sorry to go on and on, now for my question. We inspected a 1941 Taylorcraft here on the field and there is no corriosion on the fitting but there is also no tube in the center attachment point? Were the early attachments made without the tube for the bolt to pass through or do we have a problem and if so how can it be repaired? Any information would be appreciated.

Thanks,
MTH

It seems like I'm always late to the dance. But I'll try to attach some pictures from my strut attach inspection. Passed.

Howard,

it looks like it was broken out. I reposted the original message with some new photos.

Thanks,

Hi josh, Does it look like the missing material was worn away or a piece fractured out? Odd.

Lift Strut Fitting Hole Elongation

Guys,

I've just finished blasting the exterior of the left lift strut fitting and I found this scenario:

the rear strut fitting lug is torn as though a compression load was imposed on the back strut. The bolt came out easily enough (with the wing propped up) and is not bent in any way.

I put new struts on it per that AD. The old strut wasn't kinked or anything.

Has anyone else seen this sort of damage? Am I looking at replacing the fitting on that side?

Thanks,

Josh

NC24369
Reposted with new photos. Looks almost like a manufacturing defect or maybe like someone tried to drive a bolt through the fitting from the back. The last photo has the bolt inserted. There's no play in the aft fitting, despite the odd malformation.

Re: Wing Strut attach fitting A-A11 Inspection results

My attach fittings were just inspected per the AD and SB. All fine..

Re: Wing Strut attach fitting A-A11 Inspection results

take the struts up to be inspected in my F-350.
I could then see about getting the attatch fittings inspected at that time.

Our X-ray inspections here were done on assembled, flying aircraft. The guy set up the mobile X-ray machine so it captured the lower ends of the struts AND the attach fitting. An hour later, two of the five airplanes started up and flew away.

So what I am trying to say is that the T-craft uses less gas than the F350, it goes farther, and you can probably find some X-ray place within a day's flight easier than within a day's drive. This saves the whole disassembly thing, re-rigging, etc.

Our X-ray method we used here in Los Angeles HAS received an approval for AMOC (alternate means of compliance), which means you should not have any big trouble getting a similar letter from your local FAA. I will be glad to send you copies of what we got.

All you need to find is a company that offers X-ray inspection that is reasonably mobile, who can set up their "camera" under your airplane. Do some research, find a few companies within flying distance, then compare pricing. If you find a company that is closer to an airport, then they should be offering a better price because they're not driving far to do it.

IMHO You should be spending a couple or three hundred dollars on this, not a few thousand on new struts.

Bill,
No, I have not. Here in El Paso, there are no shops that can do that. I will need to find the closest shop, and put my wings on "sawhorses", and take the struts up to be inspected in my F-350.
I could then see about getting the attatch fittings inspected at that time. Does the person doing the inspecting need that handy-dandy tool that you have Forrest, or can the AD be satisfied another way.
I don't expect to have any trouble passing the attatch fitting test. The plane has been in the deserts of Arizona, and west Texas ever since the early sixties, was completely torn all the way down and re-zinc chromated in 1997, and has been constantly hangered ever since. Brie
