The precise technical steps are to be carried out in accordance with FAA Airworthiness Directive (AD) 2004-25-10 and the Boeing Alert Service Bulletins listed in the Applicability. \n- Applies only to the aircraft serials listed in Boeing Alert Service Bulletin 767-38A0062 (for 767-300 series) and 767-38A0063 (for 767-400ER series).\n- Requires compliance within 18 months after 17 March 2005. The Directive took effect on 17 March 2005.\n\n**Who is affected\n\n- Aircraft owners and operators of the affected Boeing 767-300 and 767-400ER aeroplanes (those specifically listed in the Boeing service bulletins).\n- Maintenance organisations, MROs (maintenance, repair and overhaul providers) and parts suppliers who will perform or supply the work.\n- Civil Aviation Safety Authority (CASA) enforcers who monitor compliance.\n\n**Why it matters (stated purpose and mechanical effects)\n\n- The Directive’s stated purpose is to prevent possible failure of the main deck floor stanchions and a consequent collapse of the main floor during an emergency landing. The safety risk described is passenger injury and impeded evacuation.\n- Mechanically, the Directive achieves that by mandating replacement of the waste tank cradle tie-rods and any other actions specified in the referenced FAA AD and Boeing service bulletins.\n\n**Practical implications, costs and incentives\n\n- Who pays: the aircraft owner/operator pays for parts, labour and any related downtime. Costs include purchase of replacement tie-rods, labour to install them, inspections and potential follow-on repairs.\n- Operational impact: affected aircraft must be scheduled into maintenance within the 18‑month window, which can cause downtime and scheduling trade-offs (opportunity cost of unavailable flight hours).\n- Compliance burden: operators must identify affected airframes using the Boeing service bulletins, obtain and follow the FAA AD/Boeing SB technical instructions, keep maintenance records and ensure work is done to the required standard.\n- Market effects: the cost and downtime fall on operators; larger operators or those with in‑house MRO capability may manage the workload and parts sourcing more cheaply than smaller operators that must outsource, which can create uneven cost impacts across competitors.\n- Supply/implementation risk: because the AD references external technical documents rather than reproducing full instructions, operators depend on availability of the Boeing service bulletins and FAA AD text and on parts availability. If many operators need the same parts, short-term supply pressure is possible.\n\n**Legal and administrative notes\n\n- The Directive is prescriptive: it directs operators to follow the FAA AD and Boeing service bulletins. CASA enforces compliance but the specific technical content is contained in the FAA AD and Boeing documents, so operators must consult those documents for step‑by‑step technical requirements.\n- The stated safety benefit is concrete (prevention of stanchion failure and floor collapse), but realisation of that benefit depends on correct and timely completion of the replacement and any follow-up actions specified in the referenced documents.\n\n(References: Applicability, Requirement, Compliance and Background sections of AD/B767/206.)"},"kimi_summary":{"content_quality":"ok","complexity_score":2,"scope_assessment":{"changed":false,"description":"This is a standard, narrow airworthiness directive focused on a specific mechanical defect in specific aircraft models.

Think of it as a \"recall notice\" for aircraft, but legally binding.\n\n**What it does:** It orders airlines and aircraft operators to **replace faulty waste tank cradle tie-rods** on specific Boeing 767 aircraft models. The \"waste tank cradle\" is the metal framework that holds the aircraft's toilet waste tank in place. The \"tie-rods\" are metal bars that help secure this structure.\n\n**Who it affects:** \n- **Boeing 767-300 series** and **767-400ER series** aircraft\n- Specifically those listed in two Boeing service bulletins from August 2002\n- Airlines, leasing companies, and any operator flying these aircraft in Australia\n\n**Why it matters:** The faulty parts could cause the **main floor of the aircraft to collapse during an emergency landing**. This could injure passengers and block emergency exits, preventing evacuation. The directive gives operators **18 months** from 17 March 2005 to complete the fix.\n\n**How to comply:** Operators must follow the technical instructions in a US Federal Aviation Administration (FAA) directive (AD 2004-25-10), which details exactly how to replace the parts."}},"importantCases":[],"_links":{"self":"/api/acts/ad-b767-206-waste-tank-cradle","history":"/api/acts/ad-b767-206-waste-tank-cradle/history","analysis":"/api/acts/ad-b767-206-waste-tank-cradle/analysis","conflicts":"/api/acts/ad-b767-206-waste-tank-cradle/conflicts","importantCases":"/api/acts/ad-b767-206-waste-tank-cradle/important-cases","documents":"/api/acts/ad-b767-206-waste-tank-cradle/documents"}}
