Roe Modification No. 265 (manufacturer's instruction), **or**\n  - RAAF Anson Order No. 25 (Royal Australian Air Force directive), **or**\n  - ANO 105.1.31.4.5.5 (Air Navigation Order)\n\n**Who it affects:**\n- Owners and operators of Avro Anson aircraft still flying in Australia\n- Maintenance organisations servicing these aircraft\n\n**When it applies:**\n- **\"Forthwith\"** — meaning immediately, with no grace period\n\n**Why it matters:**\nEmergency exits save lives. This directive likely addresses a discovered safety flaw in the original cockpit exit design — perhaps it was too small, poorly located, or difficult to open in a crash. The reference to RAAF orders suggests this may have originated from military operational experience where escape difficulties were identified."},"flash_summary":{"complexity_score":2,"scope_assessment":{"changed":false,"description":"The instrument's scope is confined to Avro Anson aeroplanes and to a single action: modification of the pilot's cabin emergency exit using one of three specified documents.
