The old rule (issued in 1972) required owners to inspect the alternator earth lead (the ground wire connecting the aircraft's electrical generator to the airframe) to ensure it was securely attached within 100 flight hours after February 1972.\n\n**Why it matters:** The safety check is no longer required because the compliance deadline passed over 35 years ago. Since all affected aircraft would have completed the inspection by now, the rule is redundant. This cancellation removes the outdated requirement from the rulebook."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-188-17-alternator-earth-lead-cancelled","history":"/api/acts/ad-cessna-188-17-alternator-earth-lead-cancelled/history","analysis":"/api/acts/ad-cessna-188-17-alternator-earth-lead-cancelled/analysis","conflicts":"/api/acts/ad-cessna-188-17-alternator-earth-lead-cancelled/conflicts","importantCases":"/api/acts/ad-cessna-188-17-alternator-earth-lead-cancelled/important-cases","documents":"/api/acts/ad-cessna-188-17-alternator-earth-lead-cancelled/documents"}}
