It requires inspection and modification of a critical flight control component — the **hydraulic servo actuator support assembly** (a bracket that holds part of the helicopter's steering system).\n\n**What you must do:**\n*   **Inspect** the support assembly attachment every 100 flight hours until you complete the modification\n*   **Modify** the attachment according to Bell's technical instructions (Service Bulletin 206-76-8 Rev. \"A\") before 31 December 1976\n\n**Which helicopters are affected:**\nAll Bell Helicopter Textron Canada (BHTC) 206 and Agusta Bell 206 series helicopters with specific serial numbers listed in the referenced technical documents.\n\n**Why this matters:**\nThis prevents failure of the hydraulic servo actuator attachment, which could lead to loss of flight control. The directive references equivalent safety notices from Agusta and earlier versions of this rule."}},"importantCases":[],"_links":{"self":"/api/acts/ad-bell-206-70-amdt-2-hydraulic-servo-actuator-support-assembly-inspection","history":"/api/acts/ad-bell-206-70-amdt-2-hydraulic-servo-actuator-support-assembly-inspection/history","analysis":"/api/acts/ad-bell-206-70-amdt-2-hydraulic-servo-actuator-support-assembly-inspection/analysis","conflicts":"/api/acts/ad-bell-206-70-amdt-2-hydraulic-servo-actuator-support-assembly-inspection/conflicts","importantCases":"/api/acts/ad-bell-206-70-amdt-2-hydraulic-servo-actuator-support-assembly-inspection/important-cases","documents":"/api/acts/ad-bell-206-70-amdt-2-hydraulic-servo-actuator-support-assembly-inspection/documents"}}
