The work must follow the exact procedures in Beechcraft Service Instruction No. 0187-152.\n\n**Why it matters:**\nThis rule addresses potential mechanical defects in the flight control system that could compromise the pilot's ability to control the aircraft's pitch. No aircraft covered by this directive can legally fly until this work is completed."}},"importantCases":[],"_links":{"self":"/api/acts/ad-beech-60-4-elevator-and-tab-controls","history":"/api/acts/ad-beech-60-4-elevator-and-tab-controls/history","analysis":"/api/acts/ad-beech-60-4-elevator-and-tab-controls/analysis","conflicts":"/api/acts/ad-beech-60-4-elevator-and-tab-controls/conflicts","importantCases":"/api/acts/ad-beech-60-4-elevator-and-tab-controls/important-cases","documents":"/api/acts/ad-beech-60-4-elevator-and-tab-controls/documents"}}
