This only applies if the radio has been overhauled after 19 August 1963.\n\n**Why it matters:** This ensures old radio equipment meets safety standards and prevents potentially faulty channel tuning mechanisms from being used in flight."}},"importantCases":[],"_links":{"self":"/api/acts/ad-rad-8-channel-tuning-mechanism-awa-vhf-nav-com-receiver-ad704-modification","history":"/api/acts/ad-rad-8-channel-tuning-mechanism-awa-vhf-nav-com-receiver-ad704-modification/history","analysis":"/api/acts/ad-rad-8-channel-tuning-mechanism-awa-vhf-nav-com-receiver-ad704-modification/analysis","conflicts":"/api/acts/ad-rad-8-channel-tuning-mechanism-awa-vhf-nav-com-receiver-ad704-modification/conflicts","importantCases":"/api/acts/ad-rad-8-channel-tuning-mechanism-awa-vhf-nav-com-receiver-ad704-modification/important-cases","documents":"/api/acts/ad-rad-8-channel-tuning-mechanism-awa-vhf-nav-com-receiver-ad704-modification/documents"}}
