It does two things:\n\n**What it does:**\n- **Revokes** (cancels) three existing Airworthiness Directives for Rolls Royce (Allison) AE 3007 series turbine engines — these are the engines commonly used in regional jets and corporate aircraft\n- **Remakes** those same directives as separate, standalone legal instruments\n\n**Why this matters:**\nAirworthiness Directives are legally binding safety orders that aircraft owners and operators must follow. They typically require inspections, repairs, or modifications when a safety problem is discovered with an aircraft or engine. This instrument is essentially doing \"housekeeping\" — restructuring how these safety rules are legally organised without changing their actual content.\n\n**Who it affects:**\n- Airlines and operators using aircraft with Rolls Royce AE 3007 engines (such as the Cessna Citation X and Embraer ERJ regional jets)\n- Maintenance organisations servicing these engines\n- CASA itself, for regulatory record-keeping\n\n**The bottom line:** If you own or operate one of these engines, your safety obligations haven't changed — but the legal paperwork has been tidied up so each directive now stands alone rather than being bundled together."},"flash_summary":{"complexity_score":2,"scope_assessment":{"changed":true,"description":"Overall the instrument is an administrative revocation and re-issuance of the listed Airworthiness Directives and states the re-made ADs are identical to the latest published editions (opening paras (a)–(b); Note), so the substantive obligations of the re-issued ADs are not changed by this document. However, Schedule 1 explicitly lists AD/AE 3007/1 as 'CANCELLED', which represents a concrete reduction in scope for that specific AD. Practitioners should treat the re-issuance as administratively replacing earlier documents while noting the cancellation entry in Schedule 1."},"complexity_factors":["Instrument performs a narrow administrative task: revocation and re-issue of listed ADs (opening paras (a)–(b)).","Legal source reference to delegated power under a single subregulation (subregulation 39.001(1)) limits legal layering.","Schedule lists a small, specific set of affected ADs and a single engine series (Rolls Royce (Allison) AE 3007 Series) (Schedule 1).","Note states re-made ADs are identical to latest published editions, reducing substantive legal change (Note).","One AD entry is marked 'CANCELLED', creating a targeted substantive effect that requires practitioners to check that specific item (Schedule 1).","Dependence on attached ADs (not reproduced here) means substantive details sit outside this instrument (paras (b) and Note)."],"plain_english_summary":"The instrument, signed by a CASA delegate, revokes and re‑issues the Airworthiness Directives for Rolls‑Royce (Allison) AE 3007 series engines as separate instruments, stating each remake is identical to the latest published edition.
