Required Actions

Perform an initial ultrasonic inspection for cracks of the studbolts of the inboard and outboard hinge fittings of the left and right outboard flaps. Based on inspection results, perform repetitive ultrasonic inspections, replace upper and/or lower studbolts with new or serviceable studbolts, conduct a detailed inspection for corrosion of the upper studbolts, perform a magnetic particle inspection for cracks of studbolts, and change the protection treatment as applicable.
