Here is the approach plate that I could find - although this image is a 1998 approach plate, there is a new runway, but it is the same orientation. I found the most recent approach plate via my company, but don't think I can post it. It looks almost identical to the one below.

The Margalla Hills that the plane hit are north / northwest / northeast of the airport. You can see from the missed approach, it's a immediate left turn at the end of the runway. MSA to the North is 7700 NW/9500 to the NE.
