You are correct . With enough time, money and skill it is possible to repair / rebuild anything if you find the right people. I have asked myself what I would do if I uncovered something like that on 9193 and every time my answer was fix it. In my forty years of repairing aircraft I have come in contact with some of the most skilled metal masters on Earth . They repaired stuff I would of trashed. I've also met some of the worse that thought they were the best. Those being the scary ones.
I just finished repairing a totally molested wiring job done by alarm / stero installers who I am sure thought they had done a great job. While doing so I found that someone had tied knots in the throttle cable on 9193 in a attempt at rigging. Crazy ! It was ready to break and probably would have done so at the worst time and or place.
If the owner of 1447 was near me I would consider helping the guy but a lot of what is needed is way beyond my skill level.
BTW, I have done more than a few cross Pacific flights and they are killer. Never worried about the machine. It was the crew that was my concern.
