I just read the NTSB's preliminary report:

My humble opinion : when the engine quit suddenly at 200 - 400 ft, it took the pilot by surprise. He probably was not trying to return to the runway - my guess was that he stalled very quickly with his climb attitude and when a wingdrop to the right set in, tried to correct it with right aileron. This would have deepened the stall, set the aircraft in a roll and secondary yaw, thus resulting in a spin which was unrecoverable at low height.
He obviously loved flying and contributed much to the aviation community. I feel very sorry for his young family.
