This cancellation means the specific directive no longer applies as of 17 January 2008.\n\n**What replaces it:** The requirement hasn't disappeared entirely—it's now covered by a broader general directive (AD/GENERAL/74 Amendment 1) that applies across multiple aircraft types. Owners must follow that general directive instead of this specific one."}},"importantCases":[],"_links":{"self":"/api/acts/ad-beech-90-25-front-seat-restraint-installations-modification-cancelled","history":"/api/acts/ad-beech-90-25-front-seat-restraint-installations-modification-cancelled/history","analysis":"/api/acts/ad-beech-90-25-front-seat-restraint-installations-modification-cancelled/analysis","conflicts":"/api/acts/ad-beech-90-25-front-seat-restraint-installations-modification-cancelled/conflicts","importantCases":"/api/acts/ad-beech-90-25-front-seat-restraint-installations-modification-cancelled/important-cases","documents":"/api/acts/ad-beech-90-25-front-seat-restraint-installations-modification-cancelled/documents"}}
