As of 25 September 2008, this inspection is no longer mandatory under an Airworthiness Directive. The Civil Aviation Safety Authority decided this specific maintenance task no longer warranted a mandatory safety directive.\n\n**Why it matters:** Owners of these vintage aircraft are no longer legally required to perform this specific structural inspection at three-year intervals, though they should still follow general maintenance guidelines."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-22-29-fuselage-structure-upper-cabin-inspection-cancelled","history":"/api/acts/ad-pa-22-29-fuselage-structure-upper-cabin-inspection-cancelled/history","analysis":"/api/acts/ad-pa-22-29-fuselage-structure-upper-cabin-inspection-cancelled/analysis","conflicts":"/api/acts/ad-pa-22-29-fuselage-structure-upper-cabin-inspection-cancelled/conflicts","importantCases":"/api/acts/ad-pa-22-29-fuselage-structure-upper-cabin-inspection-cancelled/important-cases","documents":"/api/acts/ad-pa-22-29-fuselage-structure-upper-cabin-inspection-cancelled/documents"}}
