The exact inspection procedure is found in Cessna Service Letter No. 310-37.\n\n**Why this matters**\nLanding gear doors are critical for safe operation. Regular inspections prevent mechanical failures that could affect landing gear deployment or create aerodynamic issues during flight."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-310-9-main-gear-door-mechanism-inspection","history":"/api/acts/ad-cessna-310-9-main-gear-door-mechanism-inspection/history","analysis":"/api/acts/ad-cessna-310-9-main-gear-door-mechanism-inspection/analysis","conflicts":"/api/acts/ad-cessna-310-9-main-gear-door-mechanism-inspection/conflicts","importantCases":"/api/acts/ad-cessna-310-9-main-gear-door-mechanism-inspection/important-cases","documents":"/api/acts/ad-cessna-310-9-main-gear-door-mechanism-inspection/documents"}}
