If any rivets are loose or \"working\" (moving), repairs must be carried out according to Cessna Service Letter ME77-6.\n\n**Why this matters:**\nLoose rivets in the wing structure can lead to serious structural failure. This directive was updated because older repairs are hard to identify visually, and the bonding materials deteriorate over time—meaning one inspection isn't enough; ongoing checks are necessary to keep these aircraft safe."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-310-32-amdt-3-lower-wing-skin-rivets","history":"/api/acts/ad-cessna-310-32-amdt-3-lower-wing-skin-rivets/history","analysis":"/api/acts/ad-cessna-310-32-amdt-3-lower-wing-skin-rivets/analysis","conflicts":"/api/acts/ad-cessna-310-32-amdt-3-lower-wing-skin-rivets/conflicts","importantCases":"/api/acts/ad-cessna-310-32-amdt-3-lower-wing-skin-rivets/important-cases","documents":"/api/acts/ad-cessna-310-32-amdt-3-lower-wing-skin-rivets/documents"}}
