Rather than maintaining separate paperwork for every aircraft model, the safety regulator (CASA) replaced this specific directive with a broader, general rule (**AD/GENERAL/74 Amendment 1**) that covers similar safety requirements across multiple aircraft types. If you own or operate a Cessna 177, you no longer need to check this particular directive, but you must still follow the replacement general rule regarding seat restraints."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-177-13-front-seat-restraint-installations-cancelled","history":"/api/acts/ad-cessna-177-13-front-seat-restraint-installations-cancelled/history","analysis":"/api/acts/ad-cessna-177-13-front-seat-restraint-installations-cancelled/analysis","conflicts":"/api/acts/ad-cessna-177-13-front-seat-restraint-installations-cancelled/conflicts","importantCases":"/api/acts/ad-cessna-177-13-front-seat-restraint-installations-cancelled/important-cases","documents":"/api/acts/ad-cessna-177-13-front-seat-restraint-installations-cancelled/documents"}}
