This inspection was mandatory for issuing a **Maintenance Release** (the official document that permits an aircraft to fly).\n\n**The change:** As of 24 September 2009, this inspection is no longer legally required. The Civil Aviation Safety Authority decided that forcing owners to keep doing this specific check was no longer justified.\n\n**Why it matters:** This removes a recurring maintenance burden and cost for operators of these aircraft."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-400-39-amdt-3-lower-wing-skin-rivets-cancelled","history":"/api/acts/ad-cessna-400-39-amdt-3-lower-wing-skin-rivets-cancelled/history","analysis":"/api/acts/ad-cessna-400-39-amdt-3-lower-wing-skin-rivets-cancelled/analysis","conflicts":"/api/acts/ad-cessna-400-39-amdt-3-lower-wing-skin-rivets-cancelled/conflicts","importantCases":"/api/acts/ad-cessna-400-39-amdt-3-lower-wing-skin-rivets-cancelled/important-cases","documents":"/api/acts/ad-cessna-400-39-amdt-3-lower-wing-skin-rivets-cancelled/documents"}}
