Revision B; Eddy current no longer approved

[alwaysoar]

With Revision B to the service bulletin eddy current current is no longer approved. So what about those who have already done eddy current? Do they now have to do one of the approved methods, xray or ultrasonic? It seems to me that Taylorcraft should be embarrassed (long ago actually), but where does the FAA stand? The AD still requires either eddy current or ultrasound. The AD trumps the SB, does it not? Or will the AD be revised?

Maybe the Canadian DOT will get onboard here!

This is why we need to keep our heads and not run around trying to do everything right away. This was done so hastily that things are bound to change.

Amen to that! IMHO the Eddy current only would show the cracks that one could see with a magnifier. The paper work has flowed back and forth a few times from Factory to FAA, the correct models and procedure WILL be in the final draft.
I talked with FAA engineer McAnaul today. Eddy current is out unless someone can send him data to support it as an AMOC . Please inspect the attach fittings thoughorly especially the inside cavity with a good borescope. That will come out as a factory SB then the FAA may make it an AD to ensure it GETS inspected.
I am posting this as an additional piece of information to ensure NO repeat of the Wiley accident. Don't shoot the messenger. I have been real busy with an Accident here at 2D1, Barber , Alliance, Oh. , last Thursday, no injury, major damage, a ship ran off end of runway and struck a passing automobile. FAA & NTSB consumed my time.

It sure would be nice if the FAA would grant an extension of time on the Nov 20th final compliance. Particularly noting that the final drafts have not even been forthcomming. Seems to me that people are getting the cart before the horse on this??

Re: Revision B; Eddy current no longer approved

I will enter that plea again, the FAA only refers to the SB for compliance, that is the control of date of compliance. I will make calls today now that I am back in gear .

I know time is short, many things cropped up during the tele conferences, aging aircraft is a common problem through out the industry.

Re: Revision B; Eddy current no longer approved

I am confused: (nothing new). If the struts were inspected under the AD and the prior SB using eddy current, then do they now have to br inspected with either ultrasonic or xray to comply?

The strut fittings are a separate issue.

Re: Revision B; Eddy current no longer approved

I stay confused in General Aviation!
Just got off phone with Andy McAnaul, FAA engineer, everyone is aware that the owners who jumped in and compiled with the original SL- SB
( as they should have done) with eddy curent may be in a pickle, however help MAY be on the way. perhaps and I say PERHAPS , that will be okay for the 24 month period.
Much is happening today. I will go to phones and stay there. I do get to look at more on the strut attach situation today from the FAA & factory.

Re: Revision B; Eddy current no longer approved

Thank you. I understood the limitations of eddy current, but since the SB came from the factory AND the FAA, it was safe to assume it was ok. NOT!.
As it turns out, unbeknownst to me, the guy who inspected the struts on my former plane did ultrasonic, not eddy current, as I was lead to believe. Thank you up there for that small favor.
