It does two things:\n\n**What it does:**\n- **Revokes** (cancels) an existing Airworthiness Directive — specifically AD/PW200/1 concerning \"Low Cycle Fatigue Count\" for Pratt & Whitney Canada PW200 series turbine engines\n- **Remakes** that same directive as a fresh, standalone legal instrument\n\n**Who it affects:**\n- Owners and operators of aircraft using Pratt & Whitney Canada PW200 series turbine engines (commonly used in helicopters and light aircraft)\n- Maintenance organisations servicing these engines\n- CASA itself, as the safety regulator\n\n**Why it matters:**\nAirworthiness Directives are legally binding safety orders. They require specific inspections, repairs, or modifications to aircraft components when a safety issue is identified. This instrument is essentially a housekeeping exercise — reissuing an existing safety requirement in a new format without changing its substance. The note confirms the directive is being remade \"in exactly the same form\" as before, ensuring continuity of safety standards while updating the legal instrument's status.\n\nThe \"Low Cycle Fatigue Count\" refers to tracking how many times an engine has been through stress cycles (starting, stopping, power changes) — critical for predicting when engine parts might fail from metal fatigue."},"flash_summary":{"complexity_score":2,"scope_assessment":{"changed":false,"description":"This instrument does not change the substantive scope of regulatory obligations. It revokes and re-makes the listed Airworthiness Directive(s) in the same form as the latest published edition, so affected parties remain subject to the same technical requirements and compliance responsibilities as before (see Schedule 1 and Note)."},"complexity_factors":["Short instrument with a single administrative action (revocation and re-making).","Clear delegation of authority referenced (subregulation 39.001(1)).","No substantive change to technical content (Note states identical form), reducing legal/operational complexity.","Primary detail is in the attached re-made Directive (Schedule 1 points to AD/PW200/1), so substantive operational requirements are not contained in this instrument itself.","Minor administrative issues (record updates, cross-references) may create small practical complexity for operators."],"plain_english_summary":"The CASA delegate revokes and re‑issues the Pratt & Whitney Canada PW200 series Airworthiness Directive (AD/PW200/1) in identical form, effectively replacing the prior instrument without changing technical requirements.
