It revokes Airworthiness Directive AD/SA 315/1, which required specific actions regarding oxygen cylinders on Eurocopter SA 315 (Lama) series helicopters. The cancellation takes effect on 26 September 2006.\n\n**Who it affects**\n\n* Owners and operators of Eurocopter SA 315 (Lama) series helicopters\n* Aircraft maintenance organisations and engineers\n\n**Why it matters**\n\nAn Airworthiness Directive (AD) is a mandatory safety instruction issued by the Civil Aviation Safety Authority (CASA). This cancellation removes the old oxygen cylinder requirements because they have been superseded by a newer directive (AD/OXY/20). Operators must now follow the replacement directive rather than the cancelled one. This update ensures safety standards remain current and consistent with international aviation regulations (specifically European standards)."}},"importantCases":[],"_links":{"self":"/api/acts/ad-sa-315-1-oxygen-cylinders-cancelled","history":"/api/acts/ad-sa-315-1-oxygen-cylinders-cancelled/history","analysis":"/api/acts/ad-sa-315-1-oxygen-cylinders-cancelled/analysis","conflicts":"/api/acts/ad-sa-315-1-oxygen-cylinders-cancelled/conflicts","importantCases":"/api/acts/ad-sa-315-1-oxygen-cylinders-cancelled/important-cases","documents":"/api/acts/ad-sa-315-1-oxygen-cylinders-cancelled/documents"}}
