:Got the MeshLint add in and went through the three meshes that are having issues and removed all n-gons.  Kind of time consuming but no too bad.  After all I only have to do one side then mirror it to get the other side. After removing all n-gons I then had Blender recalculate the normals and exported the model.  The issue is still there.
 
As a side note the last objects I discovered that had this issue are the exhaust covers.  In these I cut the holes by hand since I couldn't get the boolean operation to work.  I also cut the exhaust cutouts in the cowl by hand and at one point these were nice clean looking cutouts.  But when i did the boolean operation to do the 32 1 inch holes for the filtered air intake Blender decided to mess with the exhaust cutouts.  But at that point I don't think there where any n-gons.  But the normals problem was still there even before I tried to clean things up.  I spent some time cleaning up the air intake holes and this is where the n-gons came from.
 
I just had a close look at the exhaust covers and the one I looked at did have two n-gons.  I fixed those then flipped back to to normal and recalculated the normals and exported it.  Opening the .ac file in FG everything looked sort of OK except the inside of the mesh was bright and reflective.  This object has the normals of the front pointing outward and the normals of the back areas are pointing inward and these parts of the object are textured black.  But the back was acting like it's normals were flipped (IE. the back was black - showing the texture- on the outside when it should be showing this on the inside).  Turns out that this is acting just like the cowl and wing fairings.  So is unrelated to using a Boolean operation.
 
Thinking things through a little it appears that all of the objects that are showing up black in the FGRUN 3D preview when the normals are the correct direction are objects where I did cutouts of some sort either by hand or using a Boolean operation in Blender.  For most of these I did NOT use a boolean operation.
 
The export script definitely has issues but, at least with simpler models, works in most cases.  The way it behaves when something is not textured is very flawed in that it just fails with more or less hidden and very cryptic error messages.  I do UI work for a living and I would never let something that poorly designed out into the wild.  If it has such obvious UI issues who knows what kind of issues exist in the actually functionality.
