Bob, In short I do agree with your thinking. I too am not against corporate profit making. Perhaps it would do me some good if I also went experimental with a aircraft and therefore felt a little less confined. I just wish customer service was a bit better. Perhaps I could live with these changes more readily if I did not know the track record of ACA. I am still glad they are in business and there are good folks working there. So to get to the heart of the issues, here is just one of many examples of a lack of quality control over the years w/ ACA. A/D 2005-24-10 that applied to some citabria's because the control cable nicopress's were not swaged correctly. This went on for 5 plus years before it was caught and thankfully no one was killed. Their answer to better help you inspect the control cable after their screw up, they will provide a fifteen dollar go no go gauge. After almost killing someone it should have been free. Flash forward ten years I decide to replace control cables on a customers citabria and ask do you want me to produce or do you want factory control cables, answer factory, so at that point I contend they must have their act together and I order the cables. When I received them I looked them over and it was not a quality product, as in a sloppy job. Would they have worked yes probably but after all the drama of almost killing someone years before you could expect better. Keep in mind from my perspective correctly swaging nicopresses on a control cable should be a relatively basic skill for a A&P or repairman in that environment. They also had a huge paint issue w/ PPG paint years ago that to my liking never was resolved correctly. I am not against them doing business I just want responsible quality control. That of course comes with a price. Quality control should also go hand in hand with your license to make changes to your type certificate. Please excuse me for perhaps getting too far off topic but for me they are directly connected. Cheers to you, Brian
