The directive references two technical documents that specify exactly how and when this replacement must happen:\n- Cessna Service Letter ME75-23 (from the manufacturer)\n- FAA AD 76-13-07 (the equivalent US safety notice)\n\n**Who it affects:** Anyone who owns, operates, or maintains a Cessna 310 aircraft in Australia.\n\n**Why it matters:** Landing gear failures can be catastrophic. This AD ensures a specific mechanical defect is addressed before it causes an accident. Compliance is **mandatory** — you cannot legally fly the aircraft until the work is done as specified."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-310-44-main-landing-gear-fork-bolt-replacement","history":"/api/acts/ad-cessna-310-44-main-landing-gear-fork-bolt-replacement/history","analysis":"/api/acts/ad-cessna-310-44-main-landing-gear-fork-bolt-replacement/analysis","conflicts":"/api/acts/ad-cessna-310-44-main-landing-gear-fork-bolt-replacement/conflicts","importantCases":"/api/acts/ad-cessna-310-44-main-landing-gear-fork-bolt-replacement/important-cases","documents":"/api/acts/ad-cessna-310-44-main-landing-gear-fork-bolt-replacement/documents"}}
