This trim tab helps control whether the plane pitches up or down and reduces the force the pilot needs to apply on the controls.\n\n**How to comply:** Aircraft must be modified according to instructions in **Cessna Service Letter 65-76** before **1 September 1971**.\n\n**Why it matters:** Airworthiness Directives are legally binding safety-critical orders. Non-compliance grounds the aircraft — it cannot legally fly until the modification is complete."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-210-7-elevator-tab-actuator-modification","history":"/api/acts/ad-cessna-210-7-elevator-tab-actuator-modification/history","analysis":"/api/acts/ad-cessna-210-7-elevator-tab-actuator-modification/analysis","conflicts":"/api/acts/ad-cessna-210-7-elevator-tab-actuator-modification/conflicts","importantCases":"/api/acts/ad-cessna-210-7-elevator-tab-actuator-modification/important-cases","documents":"/api/acts/ad-cessna-210-7-elevator-tab-actuator-modification/documents"}}
