Concretely, that means installing strap assemblies on the ceiling panels and the rails that support the passenger cabin video monitors. For some aircraft the AD also requires replacing certain plate assemblies within those ceiling-panel strap assemblies with improved plate assemblies.  \n- The AD’s effective date is 20 January 2005 and it revokes the earlier AD/B747/216 (so Amendment 1 replaces the previous directive).\n\n**Who this affects**\n\n- Aircraft owners and operators of the identified Boeing 747-400 and 747-400D airframes (the directive points to a list in the Boeing service bulletin).  \n- Maintenance organisations (aircraft maintenance providers, Approved Maintenance Organisations) who must carry out the required modifications.  \n- Parts suppliers who provide the strap assemblies and replacement plate assemblies.\n\n**Why it matters (safety and mechanical effect)**\n\n- The FAA and CASA issued this AD after reports that ceiling panels holding video monitors fell into the passenger cabin when certain latch assemblies failed during turbulence.  \n- The AD mandates a retrofit: strap assemblies and, where required, improved plate assemblies to prevent ceiling panels and monitors from separating and entering the cabin. Mechanically, the directive modifies how the ceiling panels are retained so they do not detach if a latch fails.\n\n**How it works in practice (who pays, who decides, and what changes)**\n\n- Aircraft operators must schedule and fund the work (parts and labour). Compliance is mandatory and recorded in the aircraft maintenance logbooks.  \n- CASA enforces compliance in Australia by adopting the FAA AD requirement; the FAA AD and the Boeing service bulletin provide the technical steps and any specified compliance times.  \n- The practical behaviour change is: operators will incorporate the retrofit into maintenance schedules, may take aircraft out of service for the work, order parts, and use authorised maintenance providers to carry out and certify the modification.\n\n**Costs, incentives and trade-offs**\n\n- Direct cost: operators incur parts, labour and aircraft downtime costs.  \n- Incentives: operators have to perform the modification to keep the aircraft legally airworthy; MROs and parts suppliers will get business from the mandated work.  \n- Opportunity cost: scheduled maintenance windows or short-term reductions in available aircraft capacity while work is performed.  \n- Implementation risk: delay in parts supply or limited MRO capacity could increase downtime; quality of installation and correct configuration is necessary to achieve the safety objective.  \n- Compliance burden: low to moderate administrative burden (scheduling, ordering parts, maintenance log entries) but could be operationally disruptive if many aircraft require work at once.\n\n**Mechanics of legal effect and discretion**\n\n- The AD converts a manufacturer service bulletin and an FAA directive into a mandatory requirement for the listed Australian-registered aircraft by reference.  \n- CASA’s delegate sets the AD and enforces it; technical details and compliance windows come from the FAA AD and Boeing service bulletin which CASA references. Operators must follow those external documents as the means of compliance.\n\n**Market and contractual effects**\n\n- Small, concentrated benefits accrue to passenger safety and to MROs and parts suppliers listed in the service bulletin. Costs are concentrated on aircraft operators.  \n- The AD restricts operators’ freedom to postpone the modification beyond the compliance times set by the FAA AD; it does not otherwise change ownership, market entry, or competition rules.  \n\n**Source claims vs. costs and risks**\n\n- The stated purpose (prevent ceiling panels from falling into the cabin due to latch failures) is supported by incident reports cited in the AD’s background.  \n- The trade-off is obliged retrofit work with associated cost and downtime in exchange for reduced risk of in‑flight cabin debris from failing monitor supports.\n\n(References in the AD: Boeing Alert Service Bulletin 747-25A3142 Revision 3 dated 14 August 2003; FAA AD 2004-22-15 Amendment 39-13843.)"}},"importantCases":[],"_links":{"self":"/api/acts/ad-b747-216-amdt-1-video-monitor-supports","history":"/api/acts/ad-b747-216-amdt-1-video-monitor-supports/history","analysis":"/api/acts/ad-b747-216-amdt-1-video-monitor-supports/analysis","conflicts":"/api/acts/ad-b747-216-amdt-1-video-monitor-supports/conflicts","importantCases":"/api/acts/ad-b747-216-amdt-1-video-monitor-supports/important-cases","documents":"/api/acts/ad-b747-216-amdt-1-video-monitor-supports/documents"}}
