The plane was a Beech E18S N3038C. I found a photo on airliners.net @

The archvie file for KFCM,
http://archive-server.liveatc.net/kfcm/KFCM-Aug-12-2009-1630Z.mp3, has the tower providing takeoff clearance at 3:25. The tower states they are not picking up the transponder at 7:31. The helicopter 69G, reports the fire to the tower @ 8:30. I did not hear any audio from the Beech.
My condolences and prayers to the families of the pilot and passenger.
