Its scope is appropriately narrow and specific—approving one particular oxygen device on one particular aircraft with defined conditions. This matches the intended purpose of subregulation 207(2), which is to allow CASA delegates to grant specific approvals for particular operations or equipment."},"complexity_factors":["Single-purpose instrument with narrow scope (one aircraft, one specific device)","Only two operative conditions, both clearly expressed","No defined terms section (relies on external regulations)","Minimal cross-referencing (only to Civil Aviation Orders section 108.26)","No nested logic or exceptions","Total length: approximately 150 words of operative text"],"plain_english_summary":"This is a specific approval issued by the Civil Aviation Safety Authority (CASA) allowing a particular aircraft (registration VH-LJT) to use a specific type of oxygen delivery device called an \"Oxymizer\" for passengers or crew who need supplemental oxygen.\n\n**What it does:**\n- Permits the use of nasal cannula oxygen units (small tubes that sit in the nose) instead of the usual full face masks that cover nose and mouth\n- Sets strict technical requirements for how much oxygen these devices must deliver at different altitudes\n- Requires that standard face-mask oxygen units must still be available on the aircraft as backup\n\n**Who it affects:**\n- The operator of aircraft VH-LJT\n- Passengers and crew who may need oxygen during flight\n- CASA inspectors and certification staff\n\n**Why it matters:**\nThis is an example of how aviation safety regulators grant specific exemptions or alternative compliance paths for individual aircraft. Rather than forcing every aircraft to use identical equipment, CASA can approve alternative devices if they meet equivalent safety standards. The conditions ensure that even with nasal cannulas, there's adequate oxygen flow at altitude and proper backup equipment remains available."},"flash_summary":{"complexity_score":3,"scope_assessment":{"changed":false,"description":"This instrument does not broaden or alter the general regulatory scheme. It grants a narrowly targeted approval for one aircraft registration (VH‑LJT) to operate with specified nasal cannula oxygen units under technical and cross‑referenced CAO conditions. It therefore changes the operating permissions for that aircraft but does not amend the wider scope of the underlying regulations."},"complexity_factors":["Narrow, single‑aircraft scope (approval applies only to registration VH‑LJT)","Technical numeric condition for oxygen flow that varies with altitude (0.3 L/min at 10,000 ft; +0.1 L/min per 2,000 ft to 18,000 ft)","Cross‑references to other regulatory provisions (paragraph 6.1 and 5.1.2 of section 108.26 of the Civil Aviation Orders) requiring users to consult and apply additional rules","Delegated decision making under subregulation 207(2) — administrative discretion rather than a general rule","Practical compliance tasks (testing/documentation of device performance) implied but not specified in the instrument"],"plain_english_summary":"This instrument is a CASA delegate’s approval allowing the single aircraft VH‑LJT to operate fitted with Oxymizer nasal‑cannula oxygen units, subject to specified minimum flow‑rate performance by altitude and a requirement that any other individual oxygen units comply with the cited Civil Aviation Orders. It affects the VH‑LJT owner/operator, who must verify device performance and regulatory compliance to rely on the permission; the approval is narrowly tailored and signed by the CASA delegate."}},"importantCases":[],"_links":{"self":"/api/acts/casa-452-00-approval-under-subregulation-207-2","history":"/api/acts/casa-452-00-approval-under-subregulation-207-2/history","analysis":"/api/acts/casa-452-00-approval-under-subregulation-207-2/analysis","conflicts":"/api/acts/casa-452-00-approval-under-subregulation-207-2/conflicts","importantCases":"/api/acts/casa-452-00-approval-under-subregulation-207-2/important-cases","documents":"/api/acts/casa-452-00-approval-under-subregulation-207-2/documents"}}
