(Requirement)\n- It applies to all balloons operating in Aerial Work and Charter operations that are not fitted with dual blast valves or dual burners. (Applicability)\n- Compliance must be achieved before a certificate of airworthiness is issued for the balloon. (Compliance)\n\nWho it affects and who decides\n\n- Operators and owners of affected balloons pay to install and connect LPG cylinders to an approved manifold system and to secure whatever documentation or inspection is needed for approval. (Requirement) \n- The Secretary is the decision-maker who approves the manifold system. (Requirement)\n- The certificate-issuing process enforces the rule: balloons must comply before a certificate of airworthiness is issued. (Compliance)\n\nWhy it matters (as described in the text)\n\n- The directive text itself does not set out a detailed policy statement or safety justification beyond the requirement language and a note about an amendment. The Background simply records that the Directive was amended to remove from the rule balloons fitted with dual blast valves or dual burners. (Background)\n\nPractical consequences, incentives and trade-offs\n\n- Direct cost and compliance burden: affected operators must obtain and install an approved manifold and secure Secretary approval before receiving a certificate of airworthiness. This creates up-front expenditure and administrative steps. (Requirement, Compliance)\n- Administrative discretion: the Secretary’s approval creates a point of regulatory discretion; the text does not specify approval criteria or process, which may produce variability in time and effort required to secure approval. (Requirement)\n- Behavioural incentive: because the amendment excludes balloons fitted with dual blast valves or burners from the requirement, operators may choose to fit those components to avoid the manifold requirement. That creates a substitution incentive tied directly to the amendment. (Background)\n- Enforcement timing: compliance is checked at certificate issuance, so non-compliance prevents certification rather than triggering retrospective penalties.

The background explicitly states this amendment deletes coverage of balloons fitted with dual blast valves or burners. The original AD/BAL/5 likely applied to all balloons in aerial work and charter operations regardless of valve/burner configuration.

If your balloon has two separate valves or two burners, this rule doesn't apply to you.\n\n**What you must do:** Before CASA will issue you a certificate of airworthiness (official permission that your balloon is safe to fly), you must have a fuel manifold system that the Secretary (of the Department responsible for aviation) has approved.\n\n**Why it matters:** This is a safety measure to reduce fire and explosion risks. A proper manifold system ensures fuel flows safely between cylinders. The rule was updated (Amendment 1) to **narrow** who it applies to — originally it covered more balloons, but now it exempts those with dual blast valves or burners, presumably because those safety features provide equivalent protection."}},"importantCases":[],"_links":{"self":"/api/acts/ad-bal-5-amdt-1-fuel-manifold-system","history":"/api/acts/ad-bal-5-amdt-1-fuel-manifold-system/history","analysis":"/api/acts/ad-bal-5-amdt-1-fuel-manifold-system/analysis","conflicts":"/api/acts/ad-bal-5-amdt-1-fuel-manifold-system/conflicts","importantCases":"/api/acts/ad-bal-5-amdt-1-fuel-manifold-system/important-cases","documents":"/api/acts/ad-bal-5-amdt-1-fuel-manifold-system/documents"}}
