## Probable cause

The pilot's failure to verify that his seat was locked prior to takeoff.  The subsequent bounce on takeoff enabled the seat to shift aft thereby reducing the pilot's access to controls leading to the inadvertent loss of control and ground impact with trees.  Contributing factors were rough and uneven runway surface and the trees.
