It does two things:\n\n**What it does:**\n- **Revokes** (cancels) an existing Airworthiness Directive numbered AD/TURBO/1\n- **Remakes** that same directive as a new, separate legal instrument\n\n**Who it affects:**\n- Owners and operators of aircraft fitted with **Roto-Master turbochargers** (made by Rajay Industries, Inc.)\n- Aircraft maintenance engineers and organisations who must comply with airworthiness requirements\n\n**Why it matters:**\nAirworthiness Directives are mandatory safety instructions issued by CASA. They require specific inspections, repairs, or modifications to aircraft components to ensure they remain safe to fly. This instrument ensures the turbocharger inspection requirements remain legally enforceable by remaking the directive in the current legal form.\n\n**Key detail:** The note at the bottom clarifies that the directive is being remade in exactly the same form as before—this is essentially an administrative housekeeping exercise to ensure the legal instrument remains valid under current regulations, not a change to the safety requirements themselves."}},"importantCases":[],"_links":{"self":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-turbochargers","history":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-turbochargers/history","analysis":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-turbochargers/analysis","conflicts":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-turbochargers/conflicts","importantCases":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-turbochargers/important-cases","documents":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-turbochargers/documents"}}
