PA-25 NDT help

So, the new-to-me Pawnee is home, sitting on a trailer. I still need to find somebody to do the ultra-sound on the wing attach points and the lift struts. I'm north of Seattle but just brought it 1200 miles by trailer and don't mind hitting the road again if I can find somebody to do the work.
I will do the one of the terminating STC's next winter, but for now, I'm just looking to get the testing done and get it in the air. Any suggestions on where to get this done in Wa, Or or Idaho would be helpful.
I did try the Arlington glider guys but, as of yet, haven't been able to connect with the one guy they pointed me at.
Thank!
Chris

Re: PA-25 NDT help

I'm curious who they pointed you at?
Paul Neunhuis at A.I.R. used to work on the glider club's tow planes, but he retired.
I heard the new shop on the field (Skye Aero) might be gonna do their work now.
Charlie Longley who posts on the SC.org site is the owner.

Re: PA-25 NDT help

I talked to Charlie today. He didn't have anyone immediately available who could do the testing but is looking. He is supposed to get back to me. So for now, I'm still hunting.
I did find one place, Johnston Aircraft, in California that can do it. That's a really long drive with the airplane on the trailer though...

Try Anvil Corp out of Burlington. They used to do all our Ultrasonic testing of 985 cylinders for us. Great to deal with.

God put me here to accomplish a certain amount of things...right now I'm so far behind, I'll never die!!

Re: PA-25 NDT help

Any tips on the trailering, disassembly, damage enroute (hopefully not), lessons learned, etc. I've certainly entertained the option of a trailerable progject, but it always seemed too daunting. If you have time, I'd really appreciate your insights/experience. Thanks!

Re: PA-25 NDT help

I will post trailering info and photos in a few days. It went amazingly well and there were some lessons learned. Stay tuned.

Re: PA-25 NDT help

Lots of ag operations over in eastern WA, maybe one of them can help?
I know a young guy who was a crop-duster mechanic over there,
I'll ask him if he has any ideas.

Re: PA-25 NDT help

Any help is good.
I have a few places who say they will call back but still nobody who says they can actually do it, just that they might know a guy...
The thing is sitting in my driveway making me crazy! Need to fly it!

Re: PA-25 NDT help

My IA will be at my hangar on Friday, I'll ask her if she knows anyone. I'll also ask my instructors at Big Bend CC tomorrow and see if they have any leads.

Re: PA-25 NDT help

Thanks Hotrod!
I have tracked down someone who can do the inspection in Kent. Apparently Mistras has an able bodied person with an NAS-410 certification (whatever that is). The down side is that they want about $1200 to do the wing attach points and the lift struts. I can drive to Idaho and back for about $200 so I will call your guy on Monday. At least I do have a path forward though, even if it's more money than I'd like.
I am still waiting on the wing attach STC parts that will terminate one AD.
New sealed lift struts run about $3500 a side with $1000 shipping, so I'm really trying to find a cheaper inspection option. I had thought that inspection with a Maule punch was still an option but that does not seem to be the case. Can anybody verify that the latest AD requires ultra sonic inspection and does not allow a provision for using a Maule punch? I've read through the AD about a dozen times and can't find a way around the requirement for ultra sound and I couldn't find a current thread on short wing that addresses this question.
Thanks all for your input.
Chris

Re: PA-25 NDT help

$1200 sounds pretty steep, but here is a link to the Piper SB.

Edit to add, take the forks off and tap on struts, if any rust chunks come out of the strut, then I'd replace them with new ones.
