It applies to specific agricultural aircraft—the **Ayres Thrush (Snow) Commander S-2D** with serial numbers 1311D through 1365D.\n\nThe directive requires an immediate modification to a component called the **deflector cable assembly**. Owners or operators must carry out this work in accordance with the manufacturer's **Service Letter No. 43**.\n\nThe compliance requirement states \"**Forthwith**,\" which means the modification must be completed immediately before the aircraft can legally fly again. This ensures these specific crop-dusting planes meet current airworthiness standards."}},"importantCases":[],"_links":{"self":"/api/acts/ad-ac-snow-4-deflector-cable-assembly-modification","history":"/api/acts/ad-ac-snow-4-deflector-cable-assembly-modification/history","analysis":"/api/acts/ad-ac-snow-4-deflector-cable-assembly-modification/analysis","conflicts":"/api/acts/ad-ac-snow-4-deflector-cable-assembly-modification/conflicts","importantCases":"/api/acts/ad-ac-snow-4-deflector-cable-assembly-modification/important-cases","documents":"/api/acts/ad-ac-snow-4-deflector-cable-assembly-modification/documents"}}
