During the landing roll, when the dual student allowed the tailwheel aircraft to drift too close to the right side of the runway, the instructor applied left rudder and left brake. As he took this corrective action, the left main gear leg fractured and separated from the aircraft. NTSB examination of the fracture surface revealed that two fatigue cracks had initiated in corrosion pits created where the gear leg rubbed against the gear leg clamping system. The two cracks eventually combined to become one, and when loads were applied during the landing roll, an overstress separation stemming from the fatigue fracture region occurred.
Probable Cause: Separation by fracture of the left main gear leg, as the result of fatigue cracks that initiated in corrosion pits on the gear leg surface.
