The exact technical steps are contained in **Brantly Service Bulletin No. 19**, which you must follow to comply.\n\n**Why it matters:**\nThis directive addresses a specific safety defect in the helicopter's flight control system. The rudder control post attachment is critical for directional control of the aircraft, and this modification prevents potential control failures."}},"importantCases":[],"_links":{"self":"/api/acts/ad-b-2-24-rudder-control-post-upper-attachment-modification","history":"/api/acts/ad-b-2-24-rudder-control-post-upper-attachment-modification/history","analysis":"/api/acts/ad-b-2-24-rudder-control-post-upper-attachment-modification/analysis","conflicts":"/api/acts/ad-b-2-24-rudder-control-post-upper-attachment-modification/conflicts","importantCases":"/api/acts/ad-b-2-24-rudder-control-post-upper-attachment-modification/important-cases","documents":"/api/acts/ad-b-2-24-rudder-control-post-upper-attachment-modification/documents"}}
