Today I took a look at where I ground down the old side panel standoff bracket off the lower left longeron it looks like I got a little crazy and over ground. I put my straight edge on the longeron and yeah I did just little bit it was only a ½-5/8” spot but just to be safe I decided to repair that area in accordance with the A.C. 43.13-1B which for dents or damage smaller than the diameter of the tube and on longerons less than 1 inch in diameter you can use sheet of the same material and thickness and to a split sleeve patch. I bent some 0.035 sheet around a 3/4” tube and made two halves then I fishmouthed the ends and welded it in place.
