If you own or operate one of these specific aircraft, you must complete this repair or inspection to keep the aircraft legally certified to fly in Australia. This directive addresses a specific safety defect identified in the map case design of these particular early-model Cessna 150s."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-150-3-map-case","history":"/api/acts/ad-cessna-150-3-map-case/history","analysis":"/api/acts/ad-cessna-150-3-map-case/analysis","conflicts":"/api/acts/ad-cessna-150-3-map-case/conflicts","importantCases":"/api/acts/ad-cessna-150-3-map-case/important-cases","documents":"/api/acts/ad-cessna-150-3-map-case/documents"}}
