Accident happened about 11:17am according the Live ATC archives.
If you pull up KHVN 1500-1530 Right about the 16 Minute mark you hear their clearance to land. Then at 17:02 the controller mistakes the call number of the plane, pilot comes back and corrects him. Controller asks if pilot can maintain visual of the runway. Pilot says he has it. Then 17:09 you hear a quick "622!" from the pilot.
Just before the end of the file you hear someone ask for the address of the crash.
If he had visual and was fine less then 10 seconds before the crash, something had to go horribly wrong. Fast.
