AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Within 25 hours time-in-service (TIS), inspect the rod-end to determine if it can be rotated by hand. If not, determine the torque value required to rotate it. If the torque value is less than 20 Nm, inspect for a crack using magnetic particle inspection; if a crack is found, replace the rod-end assembly. If the torque value is 20 Nm or more, replace the rod-end assembly before further flight.
