The technical details of how to do the inspection are found in **Avro Technical Service Bulletin No. 80, paragraph 3.10** — operators must follow that document.\n\n**Why it matters:** This is a safety-critical requirement. The directive was originally issued in **November 1967** (hence \"11/67\") and amended once (\"Amdt 1\"). These old aircraft need ongoing structural monitoring to catch fatigue, corrosion, or damage before they become dangerous. Ignoring this AD would make the aircraft unairworthy — illegal to fly."},"flash_summary":{"complexity_score":3,"scope_assessment":{"changed":false,"description":"The instrument is labelled as Amendment 1 (AD/ANSON/19 Amdt 1), but the text supplied states a single recurring inspection requirement referencing Avro TSB No. 80 para 3.10 and an inspection interval of 100 hours.
