Wood Spar Question

[montanafos]

Figured I’d put this out there for input. Recently inspecting my wings to get ready to work on them and noticed this bit of rash and splinter that is new. Appears that something may have been pulled across the wood and it roughed the edge up slightly and caught the end of the grain and lifted it for an inch or so. The bottle cap is there for size reference. Waiting on FAR’s from my IA that he reassures me will provide clearly spelled out limitations for this type of issue. Haven’t heard anything yet so thought I’d do a bit of research myself and reach out to folks on here. My gut says it’s a glue / epoxy and revarnish when I do the wing, but sure won’t be going with just my gut. I did a search for “FAR’s for wood spar inspection and damage repair” and came up with the attached image as a part of the 46 page FAA publication. It appears that it does in fact provide limitations for such damage B/10 for instance and it appears that B = the height of the spar. I don’t see anything related to length limitations. Being more than new to this side of things, I figured I’d ask for input. The wings have been well cared for and the spars all look good (recently “inspected” and given a thumbs up) but this damage has appeared in the past couple weeks. These are in my garage, so it’s a relatively controlled environment. The damage is on the rear spar inboard of the lift strut attachment about 18”.

Very much appreciate any insight.
