Required Actions

Repetitively inspect the junction of the torque link lug and upper case of the MLG torque link assemblies for cracks. Replace any MLG torque link assembly with a Modification A39 MLG torque link assembly immediately if cracks are found, or after a certain period of time if no cracks are found. Replacing all MLG torque link assemblies with Modification A39 eliminates the need for repetitive inspections.
