If you're an airline or pilot operating an Airbus A330, you no longer need to follow the old requirements for Electronic Instrument System Display Units. Instead, follow the replacement rule (AD/A330/53) referenced in this document.\n\n**Why it matters:** This is regulatory housekeeping. The Civil Aviation Safety Authority regularly cancels outdated directives when newer, better rules take their place. This keeps the rulebook tidy and ensures operators aren't confused by conflicting requirements."}},"importantCases":[],"_links":{"self":"/api/acts/ad-a330-52-electronic-instrument-system-display-units-cancelled","history":"/api/acts/ad-a330-52-electronic-instrument-system-display-units-cancelled/history","analysis":"/api/acts/ad-a330-52-electronic-instrument-system-display-units-cancelled/analysis","conflicts":"/api/acts/ad-a330-52-electronic-instrument-system-display-units-cancelled/conflicts","importantCases":"/api/acts/ad-a330-52-electronic-instrument-system-display-units-cancelled/important-cases","documents":"/api/acts/ad-a330-52-electronic-instrument-system-display-units-cancelled/documents"}}
