Actually, that was the wrong log.txt file. I had already removed the BN-2 and was running a test to see if the SAAB 340 was going to do the same thing (it worked fine). Anyhow, I re-installed the BN-2B and ran it again, getting the same X-Plane crash. That log,txt file is attached. I did not see anything amiss when I searched the file for references to the BN-2 so I have to agree that it must be another issue with LM's Beta 15. So, I'll just refrain from using the Islander until the next beta and see if things have improved.
The KCMH issue has been going on for some time. Not sure why. That is the Columbus Glenn airport. I may just remove it.
Thanks for responding and recommendations.
