Has anyone seen "smoking rivets" in the area where the cracks the subject of the S B are on the rear spar? This has been reported on a local RV9A but I have not seen any mention of it in the inspection reports on the Forum.
Thanks, Brian. RV6, 730 hours, some aeros, no cracks. |
533 hrs, no cracks on a -7.

So...
I ordered the parts for my "in progress" wings to incorporate it now. Build Log Entry I am a little torn on how one would accomplish this now and not interfering with riveting the bottom skin and perhaps the inboard most aileron gap fairing rivet in the center of the spar. I believe one could simply use pulled rivets here...but if someone could help met get the "order of operations" figured out before I get there...I'd be grateful. |
SB complied with
Inspection completed last night...129 hours of operation, no anomalies found.

RV6A. No cracks found.
No cracks found ( SB 16-03-28 ). 662 airframe hours.
Built 1996. RV6A. C-FGIZ |
RV-6A. 1796 hrs
Built 2001 Grass since 2008, very little aerobatics since 2008 SB complied with, no cracks found. But I have a lot of rivet rash on my arms trying to get the iPhone in to get a decent photo! |
Finally inspected mine. Cracks in both wings. More obvious in the right than the left, on which it's extremely subtle. I heard somebody mention a "scratch" but that sounds like possible denial. I want to deny mine, trust me...

Dan...how many hours on your bird? (I'm guessing a lot!):) Sorry about the cracks...
|
2150ish. I suspect the cracks have been there for years.
|
Condolences - that sucks. Thanks for sharing the photos. Good eye catching that one on the left.

(sorry if this has already been mentioned, didn't want to go through the 30 pages of replies to look for it)
I received my quickbuild wings recently and was happy to find that this SB had already been complied with by Van's:  (on the downside, deburring and riveting that one hole just above the bracket will be annoying) |
RV10, no cracks
Checked mine, RV-10, 4.5 years, 880 hours, no cracks. Also, I was able to inspect thoroughly the upper aileron bracket without removing the aileron or cutting away the aileron gap fairing...by lowering the flaps to full, raising the aileron to the stop, and peeking into the top bracket with my Chinese 90 degree dental usb cam. Sweet!

1996 RV-4 cracks found
Not my plane but posting as a data point for a friend who is not active on the list.
He inspected his 1996 RV-4 and found cracks in both wings. I'm not sure of the airframe total time but probably somewhere around 1000 hours. It's a rare flight that doesn't contain loops and rolls and more :D. |
No cracks
RV-8
565 hrs, light Acro, paved runways. Used my wife's selfie stick with IPhone - got great pics. No cracks found Bruce Edwards N-391FM RV-8 |
