This document cancels them effective from the date specified within the text.\n*   **Why it matters:** The requirements in the old rule have been replaced by a newer, updated directive (**AD/CFM56/30**). Operators should now follow that new rule instead, rendering this older directive unnecessary."}},"importantCases":[],"_links":{"self":"/api/acts/ad-a320-230-high-pressure-compressor-deterioration-cancelled","history":"/api/acts/ad-a320-230-high-pressure-compressor-deterioration-cancelled/history","analysis":"/api/acts/ad-a320-230-high-pressure-compressor-deterioration-cancelled/analysis","conflicts":"/api/acts/ad-a320-230-high-pressure-compressor-deterioration-cancelled/conflicts","importantCases":"/api/acts/ad-a320-230-high-pressure-compressor-deterioration-cancelled/important-cases","documents":"/api/acts/ad-a320-230-high-pressure-compressor-deterioration-cancelled/documents"}}
