Unsafe Condition
Trunnion fittings of the wings have been manufactured with a web fillet radius smaller than the minimum required by the design data, which may induce the occurrence of fatigue cracks at the root of the trunnion fillet radius and adjacent structures (e.g., spar and ribs).
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Measure the fillet radius dimension of the trunnion fitting webs of the wings. If the fillet radius is less than 0.0394 inches (1 mm), rework the fillet radius to increase the radius, do related investigative actions, and do applicable corrective actions. If a crack is found during the investigative action, repair the structure before further flight.
