Compliance is achieved by modifying the spar per Cessna Service Letter ME74‑17, which eliminates repetitive inspections. Aircraft already modified under the previous directive remain compliant. The goal is to prevent landing‑gear attachment failure and possible collapse."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-310-35-amdt-1-main-landing-gear-aft-trunnion-support-spar-inspection-and-modification","history":"/api/acts/ad-cessna-310-35-amdt-1-main-landing-gear-aft-trunnion-support-spar-inspection-and-modification/history","analysis":"/api/acts/ad-cessna-310-35-amdt-1-main-landing-gear-aft-trunnion-support-spar-inspection-and-modification/analysis","conflicts":"/api/acts/ad-cessna-310-35-amdt-1-main-landing-gear-aft-trunnion-support-spar-inspection-and-modification/conflicts","importantCases":"/api/acts/ad-cessna-310-35-amdt-1-main-landing-gear-aft-trunnion-support-spar-inspection-and-modification/important-cases","documents":"/api/acts/ad-cessna-310-35-amdt-1-main-landing-gear-aft-trunnion-support-spar-inspection-and-modification/documents"}}
