ADs are legally binding instructions that aircraft owners and operators must follow to keep their aircraft safe and airworthy.\n\n**What it requires:** If you operate an aircraft with an **Artouste 111B** turbine engine (made by Turbomeca), you must immediately modify the **micropump valve rod**.\n\n**How to comply:** You must carry out the modification described in either:\n- Turbomeca technical document 'Mod. No. M35', or\n- Alternative directive 'AD/TURB-T/2'\n\n**When:** Immediately ('forthwith'). This means before the next flight or without delay.\n\n**Why it matters:** This fixes a specific safety defect in the engine's micropump valve rod. Operating without this modification could create an unsafe condition."}},"importantCases":[],"_links":{"self":"/api/acts/ad-artouste-4-micropump-valve-rod-modification","history":"/api/acts/ad-artouste-4-micropump-valve-rod-modification/history","analysis":"/api/acts/ad-artouste-4-micropump-valve-rod-modification/analysis","conflicts":"/api/acts/ad-artouste-4-micropump-valve-rod-modification/conflicts","importantCases":"/api/acts/ad-artouste-4-micropump-valve-rod-modification/important-cases","documents":"/api/acts/ad-artouste-4-micropump-valve-rod-modification/documents"}}
