The rule references a manufacturer service note (*Swearingen Service Note No. 062 Rev. 1*) for the specific inspection procedure.\n\n**Who is affected:** Operators of specific Metroliner/Metro II type aircraft with serial numbers T201-T287, AT001-AT065, and TC201-TC247."}},"importantCases":[],"_links":{"self":"/api/acts/ad-swsa226-22-amdt-1-elevator-quadrant-inspection","history":"/api/acts/ad-swsa226-22-amdt-1-elevator-quadrant-inspection/history","analysis":"/api/acts/ad-swsa226-22-amdt-1-elevator-quadrant-inspection/analysis","conflicts":"/api/acts/ad-swsa226-22-amdt-1-elevator-quadrant-inspection/conflicts","importantCases":"/api/acts/ad-swsa226-22-amdt-1-elevator-quadrant-inspection/important-cases","documents":"/api/acts/ad-swsa226-22-amdt-1-elevator-quadrant-inspection/documents"}}
