This had to be done before September 1971. Notably, this was a unique Australian requirement, not based on the manufacturer's own service bulletins.\n\n**What happens now:** As of 27 August 2009, owners, operators, and maintenance providers no longer need to comply with this specific directive. The Civil Aviation Safety Authority has removed the requirement because it is no longer considered necessary for safety.\n\n**Who it affects:** This primarily concerns owners and operators of Meta Sokol L.40 series aircraft, as well as aviation maintenance engineers who work on these planes."}},"importantCases":[],"_links":{"self":"/api/acts/ad-l-40-3-fire-resistant-flexible-fuel-and-oil-lines-in-engine-compartment-modification-cancelled","history":"/api/acts/ad-l-40-3-fire-resistant-flexible-fuel-and-oil-lines-in-engine-compartment-modification-cancelled/history","analysis":"/api/acts/ad-l-40-3-fire-resistant-flexible-fuel-and-oil-lines-in-engine-compartment-modification-cancelled/analysis","conflicts":"/api/acts/ad-l-40-3-fire-resistant-flexible-fuel-and-oil-lines-in-engine-compartment-modification-cancelled/conflicts","importantCases":"/api/acts/ad-l-40-3-fire-resistant-flexible-fuel-and-oil-lines-in-engine-compartment-modification-cancelled/important-cases","documents":"/api/acts/ad-l-40-3-fire-resistant-flexible-fuel-and-oil-lines-in-engine-compartment-modification-cancelled/documents"}}
