It has been moved to a newer, more general directive called **AD/GENERAL/74 Amendment 1**. So while this specific Tiger Moth directive is dead, you must still comply with the replacement rule regarding seat restraints."}},"importantCases":[],"_links":{"self":"/api/acts/ad-dh-82-8-seat-restraint-installations-modification-cancelled","history":"/api/acts/ad-dh-82-8-seat-restraint-installations-modification-cancelled/history","analysis":"/api/acts/ad-dh-82-8-seat-restraint-installations-modification-cancelled/analysis","conflicts":"/api/acts/ad-dh-82-8-seat-restraint-installations-modification-cancelled/conflicts","importantCases":"/api/acts/ad-dh-82-8-seat-restraint-installations-modification-cancelled/important-cases","documents":"/api/acts/ad-dh-82-8-seat-restraint-installations-modification-cancelled/documents"}}
