This new document completely scraps that requirement—the rule is **cancelled** as of 24 September 2009.\n\n**Why it matters:** If you own or operate one of these aircraft, you no longer need to comply with this particular installation requirement. The Civil Aviation Safety Authority (CASA) has decided this Australian-specific rule is no longer necessary, likely because the affected aircraft are now obsolete or the safety issue is addressed through other means."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-310-51-amdt-1-powerplant-fire-detection-system-installation-cancelled","history":"/api/acts/ad-cessna-310-51-amdt-1-powerplant-fire-detection-system-installation-cancelled/history","analysis":"/api/acts/ad-cessna-310-51-amdt-1-powerplant-fire-detection-system-installation-cancelled/analysis","conflicts":"/api/acts/ad-cessna-310-51-amdt-1-powerplant-fire-detection-system-installation-cancelled/conflicts","importantCases":"/api/acts/ad-cessna-310-51-amdt-1-powerplant-fire-detection-system-installation-cancelled/important-cases","documents":"/api/acts/ad-cessna-310-51-amdt-1-powerplant-fire-detection-system-installation-cancelled/documents"}}
