The requirement to have safety harnesses in these planes hasn't disappeared—it's just been moved to a newer, broader rule (**AD/GENERAL/74 Amendment 1**) that covers safety harness requirements across many aircraft types, rather than having separate rules for each specific plane model.\n\n**Who this affects:** Owners and operators of Ayres Thrush agricultural aircraft. Instead of checking this specific rule, they now follow the general safety harness requirements in the replacement directive."}},"importantCases":[],"_links":{"self":"/api/acts/ad-ac-snow-10-safety-harness-installation-cancelled","history":"/api/acts/ad-ac-snow-10-safety-harness-installation-cancelled/history","analysis":"/api/acts/ad-ac-snow-10-safety-harness-installation-cancelled/analysis","conflicts":"/api/acts/ad-ac-snow-10-safety-harness-installation-cancelled/conflicts","importantCases":"/api/acts/ad-ac-snow-10-safety-harness-installation-cancelled/important-cases","documents":"/api/acts/ad-ac-snow-10-safety-harness-installation-cancelled/documents"}}
