5K hour wing AD
 

Has anyone doen the 5,000 hour wing AD inspections? Where, How much, etc.......?
Ron

That question has been essentially answered in this forum before. Just click on "Search" at the top of this page and then enter "wing span" on the next page. You will find about 10 threads that deal with the subject.

I think Ernie meant "wing spar".

Enrie,

I read the threads---If anyone has given the name of someone that can do the inspection please point it out to me. Otherwise every one says they have done one if they need it but they don't share the source of the inspection. Sure would be nice if they left a name and number. I think they are pencil whipping these inspections. Please prove me wrong.

thanks,

Ed Coffman

mine was done by travelling NDT service out of AZO, at annual 2 years ago. Don't remember the name, I'll look it up tomorrow night. Your mech should know the name of a good local company. They do more than Skymasters, the procedure is spelled out in the AD. It straight forward, you just want it to pass, because a failure means replacing the wing.

It cost about $400.

Done at Marshall Aviation. The mech there, Eric Metzger, works on my plane and Gerry DeSantis's plane. Knows his stuff.

Doesn't Don Nieser do them? I know he is listed under Parts Sources, but he also rebuilds O2's and Skymasters. He demo'd the spar area and showed us the inspection requirements when we had the Skymaster meeting in Oklahoma.

How do I contact Don Nieser....?
Thanks

I clicked on "Search" near the top of this page, put "Nieser" and "phone" in the box, and the first thread shown had his numbers: 405-722-4079 and 405-503-4686 cell.

thanks Ernie, I put Nieser in the serch and got nothing.

The inspection is actually a two part inspection. There is the dye-penetrant inspection, which your AI should be able to do, following the AD. It requires that the upper surface of the wing be removed. The fuel tank does not have to be removed.

The second part is the actual EDDY CURRENT inspection. Mine was done by Aircraft NDT Service, Inc, 6395 Technology Drive, Suite C, Kalamazoo, MI 49009. Their phone number is 269-353-3916 (it says on the bill)

Thanks Larry. finally some real info. Muchas gracias.

5K AD specifics
 

For the archives:
5,000 hour 337 AD; 78-09-05
Carrollton, GA,
Sammy, Aircraft Services, Inc.
3-4 days, must be done there.
$1200, unless the fuel tank tops are bad, then worst case is about $2,000.

I can add an endorsement for Sammy in Carrollton. I doubt if there is a more knowledgable Skymaster IA around anywhere.

I don't think I am hard to find. Yes we have done the wing spar AD inspection on about 12 aircraft both 337's and 0-2's. We remove the top wing skins over the fuel tanks and remove the aux tanks and at least the inboard main tanks to get proper access to do the inspections. We hire specialized Non-destructive Inspection specialty companies to do the Eddy Current part of the inspection. You can contact me any of the ways below:

wing spar ad question
 

Do you have to remove the skin, tanks and all at +500?

1. In another thread entitled "Wing Spar AD" (currently a few threads below this one), on the second page, second message, another member posted the Cessna procedure, including an alternate method requiring less disassembly.

2. Don't know what you mean by "+500".

In the AD it says at 5000 hours and subsequently at 500 hours. Seems to me if I have to pull the wing skin every 500 hours it won't be long before I need new wing skin. So I'm wondering if the entire process has to be done at 500 hour intervals or just the eddy current test.

There are two tests. One is eddy current and one dye penetrant. To get there, however, you must either go through the disassembly process or the alternate process where you drill the first time a 0.625" hole to gain access. Read the posted procedure and it will be clear.

Ernie

Removing the wing skin involves lots of screws, but you will want to replace them when you remove them. If you do it carefully, it is labor intensive, but you won't have to replace the wing skin.

If the wing is riveted along the leading edge, you remove the the screws and gently lift it up to do the dye penetrant inspection. In that situation it makes sense to drill the hole. If the wing has screws along the leading edge, simply remove the top part of the wing skin, and you shouldn't have to drill the hole.

My former aircraft had rivets on the leading edge of the wing skin, and Herb's plane had screws along the leading edge of the wing skin.
You do not have to remove the tanks.

Here is a photo of the right wing panel skin removed. As Larry indicated my aircraft has screws on the lead edge so removal was pretty straight froward. Be sure to follow the Service Manual and support the wing and boom before removal. Re-installing is the fun part.
