The directive applies to life rafts with specific part numbers (D23835, 17D23336, 21D23548, 21D23541, 18D23350, 12D11751, and assembly 22D2358) that were manufactured between January 1971 and 13 August 1975.\n\n**Who it affects:** Anyone operating aircraft equipped with these specific Aircruiser life raft systems — typically airlines, charter operators, and private aircraft owners with this emergency equipment installed.\n\n**Why it matters:** Airworthiness Directives are legally binding safety instructions. Non-compliance means the aircraft cannot be considered airworthy. This particular AD addresses potential defects in life raft systems that could fail during an emergency, putting passengers and crew at risk. The reference to \"SB 111-74-1, Rev. 2\" means operators must follow the manufacturer's Service Bulletin (an official technical instruction) to complete the required work.\n\n**Key deadline:** The work had to be completed before 1 June 1979."}},"importantCases":[],"_links":{"self":"/api/acts/ad-emy-14-aircruisers-6-10-25-35-man-life-rafts-inspection-and-modification","history":"/api/acts/ad-emy-14-aircruisers-6-10-25-35-man-life-rafts-inspection-and-modification/history","analysis":"/api/acts/ad-emy-14-aircruisers-6-10-25-35-man-life-rafts-inspection-and-modification/analysis","conflicts":"/api/acts/ad-emy-14-aircruisers-6-10-25-35-man-life-rafts-inspection-and-modification/conflicts","importantCases":"/api/acts/ad-emy-14-aircruisers-6-10-25-35-man-life-rafts-inspection-and-modification/important-cases","documents":"/api/acts/ad-emy-14-aircruisers-6-10-25-35-man-life-rafts-inspection-and-modification/documents"}}
