Bit the bullet today & started riveting the right side forward skin. It is of course not without issue, the lower flange of the front doubler does not align with the bottom skin by up to 4mm, I did know about this & decided to go ahead & rivet with a plan to address the issue with the production of some doublers. The left side has the same problem, I think it stems from the heavy landing gear mount structure being a little wider than designed. I hope the landing gear fits!!!
