Congragulations to you and everyone else involved in tracking down the true source of these engine failures. You must be SO relieved to know why they failed. Of course, we are all sorry that what seems to be such a minor mistake has caused the destruction of two engines.
Further, I would like to say a few things that are based on my observations of your behavior throughout this whole ordeal. First, I want to say that it takes a moral and mature person to admit when they make a mistake--expecially a costly one. And that's exactly what you have done when you took the time to apologize to CHP for any bad PR this may have brought them. Not only did you post the apology on your webpage and on all of these forums, but you also took the time to call them up and apologize in person. You are a good man Andy.
But my observations do not stop there. Throughout this whole ordeal you have been very hesitant to formally place any blame on the manufacturer. In the end, through sound logic you were able to determine the true failure mode and it turned out not to be the manufacturer's fault at all. I really respect the approach you have taken, and your ability to remain rational and not become bitter towards to manufacturer for what might have been their mistake [but obviously turned out not to be]. I think we can all learn an important lesson--one of self control--from what you have shared with us.
In addition, I want to thank you for taking the time you have to share all of this with--well--all of us. I'm sure your documention will save many others from making the same mistake.
It's a pleasure to know you Andy. I can't wait to see pictures of the new hardware rolling in for the TNT 383! I'm sure you are sleeping better knowing the true cause of the engine failures. And I'm sure you are going to learn a lot from performing the rebuild yourself...
