Human Factors
During a tailwheel transition training flight; the aircraft departed the runway surface on landing. The winds upon time of landing favored Runway XX and a right-crosswind component of about 10 knots was present at the time of the occurrence. No other traffic was in the pattern and the approach was stable throughout. The touchdown was in a three point attitude and did not bounce. On the rollout; the student improperly managed rudder control and the aircraft rapidly developed a significant turn to the left. As Instructor; I took control of the aircraft and stopped the ground loop from further developing. The aircraft departed the hard surface of the runway at roughly a 10 degree angle at a fairly slow speed and came to rest in the grass about 20 feet from the edge of the runway. Upon shutting the airplane down; both the student and I exited the airplane to assess the situation. No signage or lighting was hit nor was there any damage present on the airplane. The grass was smooth and no holes were present.The situation developed from a normal crosswind landing to a runway excursion quickly. The cause was an improper control input by the student that was not caught in time by me; the instructor. Despite not reacting in time to prevent the excursion; the aircraft did not ground loop and no damage was sustained by the airplane. Any corrective action would be on my part as the Instructor; to take control sooner before such a significant turn could develop.
PA-12 Instructor Pilot reported his student lost directional control on the landing roll resulting in a runway excursion.
