Not Repaired Thread friction COF of 0.42 was credited in evaluation showing torque applied during a 2010 stall event was not adequate to fail pin. However, the evaluation remains SAT if COF-0.1.
Additionally, the pin's shear torque excluding thread friction has 80% margin over design basis torque. Repairs tentatively planned for outage in Spring of 2019.
