Looking at the last log file, it's telling me X-Plane has shut down correctly with a clean exit. (See image)
I'm not really sure what is happening, but if it is crashing with a clean exit in the middle of loading the sim, try loading the TBM at a test scenery. Many developers like to use SCIP, because it's small and has very little scenery, so loading time is fast. If it loads without problems, then the problem lies with your LOWS scenery.
Try removing the JarDesign Ground Traffic plugin from your LOWS scenery, and if this doesn't work, it might be the scenery itself. First, try all these steps and then post back results with log files.
