Probable cause

The failure of the pilot in command to adequately configure the aircraft for the takeoff portion of a touch and go.

Analysis

The pilot stated he was on a local familiarization flight with a swiss national friend, reported to be a certificated private pilot. He said he planned to do a touch and go landing, but neglected to reconfigure the aircraft after landing for the takeoff portion. He applied full takeoff power with full flaps down and mixtures leaned. The owner/pilot was flying the aircraft from the right front seat. The aircraft became airborne prematurely and started to roll to the right, his reaction was to retract the landing gear and retard the throttles. At about that time, the right wing struck the runway and started the crash sequence.
