It has been replaced by a broader, general safety directive (**AD/GENERAL/74 Amendment 1**) that covers this requirement across multiple aircraft types rather than singling out the DHC-3 Otter.\n\n**Who it affects:** Owners and operators of DHC-3 Otter aircraft who were previously subject to the 1972 directive. They must now comply with the general directive instead.\n\n**Why it matters:** This streamlines aircraft safety regulations by consolidating specific rules into general ones, reducing regulatory clutter while maintaining the same safety standards."}},"importantCases":[],"_links":{"self":"/api/acts/ad-dhc-3-27-front-seat-restraint-installation-cancelled","history":"/api/acts/ad-dhc-3-27-front-seat-restraint-installation-cancelled/history","analysis":"/api/acts/ad-dhc-3-27-front-seat-restraint-installation-cancelled/analysis","conflicts":"/api/acts/ad-dhc-3-27-front-seat-restraint-installation-cancelled/conflicts","importantCases":"/api/acts/ad-dhc-3-27-front-seat-restraint-installation-cancelled/important-cases","documents":"/api/acts/ad-dhc-3-27-front-seat-restraint-installation-cancelled/documents"}}
