This cancellation removes the outdated requirement to avoid confusion and ensure operators follow the current standard.\n\n**Key details**\n*   **Cancelled**: AD/SWSA226/85 Amdt 1 (Flight Envelope Restriction)\n*   **Replacement**: AD/SWSA 226/95\n*   **Effective**: 25 October 2007"}},"importantCases":[],"_links":{"self":"/api/acts/ad-swsa226-85-amdt-1-flight-envelope-restriction-cancelled","history":"/api/acts/ad-swsa226-85-amdt-1-flight-envelope-restriction-cancelled/history","analysis":"/api/acts/ad-swsa226-85-amdt-1-flight-envelope-restriction-cancelled/analysis","conflicts":"/api/acts/ad-swsa226-85-amdt-1-flight-envelope-restriction-cancelled/conflicts","importantCases":"/api/acts/ad-swsa226-85-amdt-1-flight-envelope-restriction-cancelled/important-cases","documents":"/api/acts/ad-swsa226-85-amdt-1-flight-envelope-restriction-cancelled/documents"}}
