This directive is a **precautionary safety measure** to catch similar cracks in actual aircraft before they become dangerous.\n\n**Who must comply:** Anyone operating any model of the EMB-110 series in Australia.\n\n**How to comply:** Follow the specific inspection procedures detailed in **Embraer Service Bulletin 110-57-012** (the manufacturer's official technical instruction)."},"flash_summary":{"complexity_score":3,"scope_assessment":{"changed":false,"description":"The AD implements a precautionary inspection requirement consistent with the manufacturer's fatigue-test findings.
