The flight instructor reported that, during a touch and go landing in a crosswind, and the student pilot on the controls, the airplane touched down on the runway centerline, "but without perfect longitudinal (heading) alignment", and the airplane veered left. The instructor took control of the airplane, added power to takeoff, but did not retract any of the "partial" flaps. She maintained the "slightly" offset direction during the takeoff roll and the airplane became airborne as it exited the left side of the runway. The left wing impacted trees and brush. Subsequently, the airplane came to rest at the bottom of a ravine.
The airplane sustained substantial damage to the right wing.
The flight instructor reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
The automated weather observation station located at the accident airport reported that, about the time of the accident, the wind was 330° at 7 knots, gusting to 14 knots. The airplane landed on runway 6.
