Scratch, have you tried the highmemfix=1 entry in your fsx.cfg? That's supposed to eliminate these sorts of problems. I find them when there's a missing texture in the model, and when the video card is over-driven. While there might be a missing texture in this case, it's much more likely that all those HD textures are straining your video card. Do a search on the Avsim FSX forum for highmemfix and you'll see how to use it and where to put it.
Yup, I've tried all of those and have re downloaded it from Carenado and reinstalled it twice. No other a/c I have are affected except for not having any shiny aluminum textures on any of them.
