ADs are legally binding; aircraft cannot fly unless they comply.\n\n**Who it affects:** Owners and operators of **Meta Sokol L.40 series aircraft** (a specific model of aeroplane).\n\n**What it requires:** Operators must inspect and modify the fuel lines on these aircraft exactly as described in **Service Bulletin No. 11/L.40** (an external technical document published by the manufacturer). The directive doesn't spell out the specific mechanical steps here — it simply mandates compliance with that bulletin.\n\n**Deadline:** The work had to be completed **before 1 May 1976**.\n\n**Why it matters:** Fuel line defects can cause leaks and catastrophic fires. This directive forces operators to fix a specific, identified safety issue rather than relying on voluntary maintenance."}},"importantCases":[],"_links":{"self":"/api/acts/ad-l-40-10-fuel-line-inspection-and-modification","history":"/api/acts/ad-l-40-10-fuel-line-inspection-and-modification/history","analysis":"/api/acts/ad-l-40-10-fuel-line-inspection-and-modification/analysis","conflicts":"/api/acts/ad-l-40-10-fuel-line-inspection-and-modification/conflicts","importantCases":"/api/acts/ad-l-40-10-fuel-line-inspection-and-modification/important-cases","documents":"/api/acts/ad-l-40-10-fuel-line-inspection-and-modification/documents"}}
