Has anyone heard of any cracked angles found yet?

Yes, there have been two T-6s that I specificly know of that have had cracks found on the wing attach angles. They were on the top angles and they are being replaced. I cant say who they belong to but they are both owned by the same group.
This has been an extremely important inspection and AD from what I have seen so far. Does anyone else have any reports from inspections performed?

I have found one cracked angle on the inspections I have done. It was on an upper angle however the crack ran vertically from a bolt hole out (not towards the radius). I don't feel this is a result of any overstress or fatigue. It was just a crappy job of replacing an angle at one time by sombody that didn't get the allignment of the new angle correct or possibly somebody prying with a punch real hard to align the bolt holes while hanging the wing.
I think this inspection is a real good inspection for the fleet just because it is forcing people to take a good look at these angles. I personally don't think many (if any) fatigue cracks will be found but I do think there will be a lot of corroded angles found.

NATA and EAA/WOA have a questionnaire on this web site, please fill it out so we will have the same data as the FAA, thanks

We have found no cracks but do have inter-granular corrision on two of our angles.
