However, since the original inspection was required to be done by 1974 (or within 100 flight hours after), all affected aircraft would have completed this decades ago.\n\n**What it does:** It formally cancels (revokes) the airworthiness directive as of 31 July 2008, removing the legal requirement from the books.\n\n**Why it matters:** Airworthiness directives are legally binding safety instructions. This cancellation cleans up the regulatory framework by removing an obsolete requirement that everyone has already complied with, reducing unnecessary regulatory clutter."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-31-30-rudder-and-nose-gear-steering-cable-inspection-cancelled","history":"/api/acts/ad-pa-31-30-rudder-and-nose-gear-steering-cable-inspection-cancelled/history","analysis":"/api/acts/ad-pa-31-30-rudder-and-nose-gear-steering-cable-inspection-cancelled/analysis","conflicts":"/api/acts/ad-pa-31-30-rudder-and-nose-gear-steering-cable-inspection-cancelled/conflicts","importantCases":"/api/acts/ad-pa-31-30-rudder-and-nose-gear-steering-cable-inspection-cancelled/important-cases","documents":"/api/acts/ad-pa-31-30-rudder-and-nose-gear-steering-cable-inspection-cancelled/documents"}}
