I had used a shop on my home base for the prebuy evaluation and subsequent three annuals. When I relocated the plane to a new home base, I used a new shop at this location for my annual this year. As part of the annual, he did a preliminary inspection of the plane and documents. Prior to this, he only had done an oil change and replaced a nonfunctioning oil heating element on the plane. He immediately discovered discrepancies in the 337, as well as issues with the wings. He called me to inform me that he could not state the plane was airworthy but did not know the extent of the issues. He told me I could get a second opinion or have him do a more complete inspection of the plane and get a better idea of what was wrong so that I could know what needed to be done to get it airworthy. I chose the latter, and this resulted in a 60+ page report of his findings. This report was seen by a number of other mechanics including the original shop, and a wing repair shop, and no one disputes his findings or conclusions.
Sorry you think my posts are rage bait. I do not believe it is. If it was, I would have mention names, etc. I think I pretty much laid out the facts without much emotion or commentary. Am I disappointed, yes. Am I happy with the situation, no. Do I think the original shop has done me a disservice, and should take responsibility, and accountability for their misses, yes. There is concern from the mechanic as well as those that reviewed his report that discovered the missed issues that a wing could fall off in flight given the issues he found. Certainly, its flight parameters for VA, VNO, and VNE are clearly affected. Also, because of the angles of the wings not being correct its stall characteristics, and tendency to spin, or spiral and recover are affected as well. Since I tend to be extremely conservative in my flying I fortunately did not experience any of this, but I also fly in an area where sudden turbulence, and pop-up storms are quite common, so the risk was certainly there. I also do a lot of maneuver practice, and this includes power on and power off stalls and the consequences thereof with altered stall characteristics.
