The original rule required compliance by September 1971, but now that deadline—and the requirement itself—is wiped out. If you own one of these planes, you no longer need to perform the modifications that were previously mandated.\n\n**In short:** A decades-old fire safety upgrade requirement for these specific aircraft has been permanently cancelled."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-25-8-improved-protection-from-crash-fires-cancelled","history":"/api/acts/ad-pa-25-8-improved-protection-from-crash-fires-cancelled/history","analysis":"/api/acts/ad-pa-25-8-improved-protection-from-crash-fires-cancelled/analysis","conflicts":"/api/acts/ad-pa-25-8-improved-protection-from-crash-fires-cancelled/conflicts","importantCases":"/api/acts/ad-pa-25-8-improved-protection-from-crash-fires-cancelled/important-cases","documents":"/api/acts/ad-pa-25-8-improved-protection-from-crash-fires-cancelled/documents"}}
