Pulled the fabric off of a '79 model PA-18-150 today, and found this front spar in the left wing. Anyone seen this before? It looks to be a short-wing spar that was re-drilled and spliced. See photos of lift strut holes and doubler rivet holes, as well as other unused holes. No record in the logs or 337's of course, but I do know this fabric has been on since 1989. I know the splice is a legit process and have seen the Piper data for doing it, but can it be legally done from a short-wing spar? Is it possible this came from Piper? Only reason I ask is the tape/sticker with the "PA-18" and "12/2x/1978". This red marker/pencil looks similar to writing Ive seen on other spars from the factory, but obviously anyone can write anything on a piece of masking tape. I don't mind changing the spar, I'm just curious if anyone else has come across this...
