I live about 30 miles from this crash site and have flown into KTRK many times.
On a good day this is a demanding airport, 5900msl.
go to airnav.com and you can download the approach plates.
I called the airport and couldn't get any data including which runway they were trying for and which approach they had made.
wx at the time aabout 1500 broken 3-4 miles wind from ssw at 10-15 AT THE SURFACE...tops of the mountains gusts to 80 knots nearby.
some reports indicate great wing rocking(90 degree bank to 90 degree bank)
