The preliminary NTSB report is online now.
http://www.ntsb.gov/NTSB/brief.asp?e...26X00678&key=1

There appears to be no indication of engine failure, fuel exhaustion, fire,
or control malfunction. The fuel controls (throttle idle and bent; mixture
rich; both tanks selected) are consistent with spin recovery procedures.
Weather was benign. The weights of the persons on board are not mentioned.
