Required Actions
Performing a tactile inspection of each hinge for friction points, measuring for play in the drag plane, measuring the tightening torque of each spindle bolt. If the tightening torque is not within the minimum and maximum torque, dye-penetrant inspecting the spindle bolt for a crack and removing the spindle bolt and hexagonal castellated nut from service. If the tightening torque is within the minimum and maximum torque, inspecting the spindle bolt for corrosion and fretting. Inspecting the bearing race inner ring and bearing needles for spalling and replacing the bearing race if there is any spalling. Measuring the thickness of each stop washer and removing the stop washer from service if the thickness is less than 1.5 mm (.060 inch). Inspecting the inner ring for brinelling. If there is brinelling deeper than 0.1 mm (.004 inch), repairing the hinge. If there is brinelling 0.1 mm (.004 inch) or less, dye-penetrant inspecting the inner ring for a crack.
