The solo student pilot reported that, during the takeoff roll the pilot's side window blew open as full power was applied. He added that he "reached over with [his] right hand to close [the] window," but as he did so, the airplane veered off the runway to the left into a wooded area and impacted terrain. The student pilot reported that he had noticed on previous flights that the window latch was loose, and he had planned to get it fixed, but had not done so.

Both wings sustained substantial damage.

The student pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
