Rather than listing the exact time limits in the rule itself, this directive points operators to **Chapter 5 of the Cessna Maintenance Manual** (the September 1971 edition with 1980 updates) to find the specific retirement schedule for each part.\n\n**Why it matters**\n\nLanding gear undergoes extreme stress during takeoff and landing. This rule prevents catastrophic structural failures caused by metal fatigue by ensuring components are retired before they become unsafe."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-500-5-amdt-1-landing-gear-structural-life-limitation","history":"/api/acts/ad-cessna-500-5-amdt-1-landing-gear-structural-life-limitation/history","analysis":"/api/acts/ad-cessna-500-5-amdt-1-landing-gear-structural-life-limitation/analysis","conflicts":"/api/acts/ad-cessna-500-5-amdt-1-landing-gear-structural-life-limitation/conflicts","importantCases":"/api/acts/ad-cessna-500-5-amdt-1-landing-gear-structural-life-limitation/important-cases","documents":"/api/acts/ad-cessna-500-5-amdt-1-landing-gear-structural-life-limitation/documents"}}
