Ground crew might see \"turbo\" on a plane and mistakenly pump jet fuel (turbine fuel) into an aircraft that requires avgas (aviation gasoline). Piston engines fail catastrophically if filled with jet fuel. Removing the \"turbo\" label makes it clear the plane is a piston-engine type that needs avgas.\n\n**What must be done:** Scrub off, paint over, or otherwise obliterate any \"turbo\" branding from the aircraft's exterior—including logos, decals, or lettering.\n\n**Compliance:** Aircraft owners were required to complete this modification before 1 July 1987."}},"importantCases":[],"_links":{"self":"/api/acts/ad-general-62-amdt-1-turbo-insignia","history":"/api/acts/ad-general-62-amdt-1-turbo-insignia/history","analysis":"/api/acts/ad-general-62-amdt-1-turbo-insignia/analysis","conflicts":"/api/acts/ad-general-62-amdt-1-turbo-insignia/conflicts","importantCases":"/api/acts/ad-general-62-amdt-1-turbo-insignia/important-cases","documents":"/api/acts/ad-general-62-amdt-1-turbo-insignia/documents"}}
