The check pilot did not act in a timely manner to prevent the airplane from departing the runway's edge. The airplane subsequently struck a drainage ditch and sustained substantial damage to the fuselage. The pilots reported no preimpact mechanical failures or malfunctions with the airplane that would have precluded normal operation. ## Factual narrative During a practice touch and go landing on a check flight for a pilot, new to the airplane, the pilot receiving the check lost directional control of the tail wheel equipped airplane on the landing roll and drifted towards the right.
