Narrative:
Upon landing, aircraft swerved to left. Full right rudder and aileron were applied but aircraft continued until it ran off runway onto side grass. No damage to airplane was noted. Gear was visually checked with great detail to nose gear and all appeared in order. Flight was made next day to crg and aircraft did same but more violently and after check by mechanic, a nose scissors bolt was found to be sheared allowing gear to turn left. Better preflight action may have detected this belt shear, but without removing parts, it would be hard to detect. Also, I thought that pilot error could have caused the left turning action. Winds were very gusty and from right at landing.
