If you don't comply, you can't fly the aircraft. This remaking process ensures the safety rules remain technically current and legally valid, even though the actual safety requirements haven't changed — the note explicitly states each directive is being \"re-made in exactly the same form\" as before. This is likely a housekeeping exercise to ensure proper legal form under the Civil Aviation Safety Regulations 1998."}},"importantCases":[],"_links":{"self":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-mikoyan-and-gurevich-mig-15-series-aeroplanes","history":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-mikoyan-and-gurevich-mig-15-series-aeroplanes/history","analysis":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-mikoyan-and-gurevich-mig-15-series-aeroplanes/analysis","conflicts":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-mikoyan-and-gurevich-mig-15-series-aeroplanes/conflicts","importantCases":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-mikoyan-and-gurevich-mig-15-series-aeroplanes/important-cases","documents":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-mikoyan-and-gurevich-mig-15-series-aeroplanes/documents"}}
