It does two things:\n\n**What it does:**\n- **Revokes** (cancels) two existing Airworthiness Directives for a specific type of vintage aircraft — the DH 94 Moth Minor series aeroplanes\n- **Remakes** those same directives as separate, standalone legal instruments\n\n**Who it affects:**\n- Owners and operators of DH 94 Moth Minor aircraft (a British light aircraft from the 1930s-40s)\n- Aircraft maintenance engineers who work on these planes\n- CASA itself, as the aviation safety regulator\n\n**Why it matters:**\nAirworthiness Directives are mandatory safety instructions — like recall notices for aircraft. They require specific inspections, modifications, or operational limits to keep planes airworthy. This instrument ensures two safety rules remain in force:\n- **AD/DH 94/1 Amdt 1**: Flight limitations (restrictions on how the aircraft can be flown)\n- **AD/DH 94/2**: Safety harness installation requirements (ensuring pilot restraints work properly and are replaced before they wear out)\n\nThe \"revoke and remake\" process is an administrative housekeeping measure. It doesn't change the actual safety requirements — the note explicitly states each directive is being remade \"in exactly the same form\" as before. This likely reflects a reorganization of how CASA structures its legal instruments under the Civil Aviation Safety Regulations 1998."},"flash_summary":{"complexity_score":2,"scope_assessment":{"changed":false,"description":"The instrument does not change the substantive scope of regulatory obligations. It revokes the listed Airworthiness Directives and remakes each one \"in exactly the same form as appears in the latest published edition of the Directive\" (Note). The titles of the remade ADs remain the same as listed in Schedule 1 (Flight Limitations AD/DH 94/1 Amdt 1; Cockpit Safety Harness Installation - Integrity and Lifing AD/DH 94/2). The practical effect is administrative re-issuance rather than a change in scope or technical requirements (subregulation 39.001(1); Schedule 1; Note)."},"complexity_factors":["Short, single-purpose instrument consisting of a revocation and re-issuance","Limited number of operative clauses (revoke specified ADs; remake them as separate instruments)","No technical or operational requirements set out in the instrument itself—substantive rules are in the attached ADs","References a delegated power (subregulation 39.001(1)), requiring readers to understand delegation context","Administrative effects (revocation/record updates) require checking attached/published ADs to confirm substantive obligations"],"plain_english_summary":"This instrument revokes and re-issues two Airworthiness Directives affecting DH 94 (Moth Minor) aeroplanes — covering flight limitations and cockpit safety harness lifing — as fresh, separate instruments in the same form as the latest editions.
