The modification must follow the procedures in Aero Commander Service Bulletin No. 89.\n\n**Why it matters:** This addresses a safety defect that could potentially cause loss of control of the aircraft if the cable retainer fails. Compliance is mandatory and immediate."}},"importantCases":[],"_links":{"self":"/api/acts/ad-ac-32-aileron-cable-drum-cable-retainer-modification","history":"/api/acts/ad-ac-32-aileron-cable-drum-cable-retainer-modification/history","analysis":"/api/acts/ad-ac-32-aileron-cable-drum-cable-retainer-modification/analysis","conflicts":"/api/acts/ad-ac-32-aileron-cable-drum-cable-retainer-modification/conflicts","importantCases":"/api/acts/ad-ac-32-aileron-cable-drum-cable-retainer-modification/important-cases","documents":"/api/acts/ad-ac-32-aileron-cable-drum-cable-retainer-modification/documents"}}
