The inspection must follow Beechcraft's Service Instruction No. 0895.\n\n**Who it affects:** Anyone who owns or operates the listed Beechcraft aircraft fitted with these specific Goodyear fuel cells — mostly older twin-engine propeller aircraft from the 1960s-70s.\n\n**Why it matters:** Fuel cells are flexible fuel tanks inside the wings. If they leak or fail, you get fuel leaks, fire risk, and potential engine failure. This AD prevents that by mandating regular checks.\n\n**What you must do:**\n- **First inspection:** Within 100 flight hours after 30 June 1978\n- **Repeat inspections:** Every 12 months thereafter\n\n**Key note:** If you already complied with the earlier directive AD/BEECH 70/19, that counts as compliance with this one — you don't need to do it twice."}},"importantCases":[],"_links":{"self":"/api/acts/ad-beech-65-49-amdt-1-goodyear-fuel-cells","history":"/api/acts/ad-beech-65-49-amdt-1-goodyear-fuel-cells/history","analysis":"/api/acts/ad-beech-65-49-amdt-1-goodyear-fuel-cells/analysis","conflicts":"/api/acts/ad-beech-65-49-amdt-1-goodyear-fuel-cells/conflicts","importantCases":"/api/acts/ad-beech-65-49-amdt-1-goodyear-fuel-cells/important-cases","documents":"/api/acts/ad-beech-65-49-amdt-1-goodyear-fuel-cells/documents"}}
