It keeps the firewall inspection requirement but removes other technical instructions—specifically, operators no longer need to follow Service Bulletin 71-08 under this rule, and requirements from Service Bulletin 05-02 have been moved to a separate safety directive (AD/AS 355/36)."}},"importantCases":[],"_links":{"self":"/api/acts/ad-as-355-24-amdt-2-consolidation-of-early-airworthiness-directives","history":"/api/acts/ad-as-355-24-amdt-2-consolidation-of-early-airworthiness-directives/history","analysis":"/api/acts/ad-as-355-24-amdt-2-consolidation-of-early-airworthiness-directives/analysis","conflicts":"/api/acts/ad-as-355-24-amdt-2-consolidation-of-early-airworthiness-directives/conflicts","importantCases":"/api/acts/ad-as-355-24-amdt-2-consolidation-of-early-airworthiness-directives/important-cases","documents":"/api/acts/ad-as-355-24-amdt-2-consolidation-of-early-airworthiness-directives/documents"}}
