(Document)"],"plain_english_summary":"What this directive does, mechanically\n\n- Requires a specific hardware modification to inflatable escape slides identified as Air Cruiser part numbers 15D22129 and 15D22129-1 when those slides are fitted to Boeing 727 aircraft. (Applicability)\n- Directs operators to carry out the modification using the procedures in Garrett Air Cruiser Service Bulletin No. 114-65-3. (Document)\n- Makes compliance mandatory immediately — the time for compliance is “forthwith.” (Compliance)\n\nWho is affected\n\n- Aircraft operators and owners who have Boeing 727s equipped with Air Cruiser P/N 15D22129 or 15D22129-1 escape slides are directly affected. (Applicability)\n- Maintenance organisations, technicians and parts suppliers who must perform or support the modification will be involved. (Document)\n\nWho decides and who pays\n\n- The Civil Aviation Safety Authority issues and enforces the directive under the Civil Aviation Regulations 1998 (Part 39). The directive itself specifies the required action and timing. (Civil Aviation Safety Authority; Part 39)\n- Costs for parts, labor, aircraft downtime and any associated logistics are borne by the aircraft owner/operator who must carry out the modification. (Applicability; Document; Compliance)\n\nWhy it matters (stated purpose and practical implications)\n\n- The instrument’s title and the required modification indicate the directive is intended to address an airworthiness or safety issue with the specified inflatable escape slides. The directive effects that aim by mandating a technical change to those parts. (Title; Document)\n- Mechanically, affected operators must schedule the work, obtain or implement the Service Bulletin’s instructions, and certify the aircraft as compliant before continuing operations if the issue prevents safe operation. Because compliance is required \"forthwith,\" operators face immediate scheduling and resource decisions. (Document; Compliance)\n\nCosts, incentives and trade-offs (practical factors to consider)\n\n- Compliance burden and direct costs: operators must pay for the modification (parts and labor), absorb aircraft downtime, and possibly reallocate maintenance slots on short notice. (Applicability; Document; Compliance)\n- Implementation risk: success depends on availability of parts and qualified personnel, and on clear, implementable instructions in the referenced Service Bulletin. If parts or technicians are limited, compliance timing may be delayed despite the \"forthwith\" requirement. (Document; Compliance)\n- Regulatory discretion and enforcement: the Civil Aviation Safety Authority determines compliance requirements and enforces them under Part 39; operators are required to follow the AD as written. (Civil Aviation Safety Authority; Part 39)\n\nEffects on private choice and market participants\n\n- The directive constrains operators’ choices by mandating a specific modification method (the Garrett Service Bulletin). Operators cannot substitute alternative fixes without regulatory approval. (Document)\n- Maintenance providers and parts suppliers may see concentrated demand for the specified modification, while operators incur the diffuse costs of purchasing and installing the modification. (Applicability; Document)\n\nSummary statement\n\n- This airworthiness directive mandates an immediate modification of specified Air Cruiser inflatable escape slides on Boeing 727 aircraft, using Garrett Service Bulletin No. 114-65-3. It assigns decision and enforcement authority to the Civil Aviation Safety Authority, places compliance costs and scheduling obligations on affected aircraft owners/operators, and creates an immediate requirement for maintenance action.

It requires a specific modification to emergency escape slides on certain Boeing 727 aircraft.\n\n**What it does:**\n- Orders airlines and aircraft operators to modify inflatable escape slides made by Air Cruiser (part numbers 15D22129 and 15D22129-1)\n- The modification must follow the manufacturer's Service Bulletin No. 114-65-3\n- Compliance is required \"forthwith\" — meaning immediately, without delay\n\n**Who it affects:**\n- Operators of Boeing 727 aircraft fitted with these specific Air Cruiser escape slides\n- Maintenance organisations servicing these aircraft\n\n**Why it matters:**\nAirworthiness Directives are legally binding safety instructions. They typically issue when a defect, unsafe condition, or design flaw is discovered that could affect flight safety. In this case, the modification to the inflatable escape slides is deemed urgent enough to require immediate action. Non-compliance can ground aircraft and result in penalties."}},"importantCases":[],"_links":{"self":"/api/acts/ad-emy-3-amdt-1-inflatable-escape-slides-modification","history":"/api/acts/ad-emy-3-amdt-1-inflatable-escape-slides-modification/history","analysis":"/api/acts/ad-emy-3-amdt-1-inflatable-escape-slides-modification/analysis","conflicts":"/api/acts/ad-emy-3-amdt-1-inflatable-escape-slides-modification/conflicts","importantCases":"/api/acts/ad-emy-3-amdt-1-inflatable-escape-slides-modification/important-cases","documents":"/api/acts/ad-emy-3-amdt-1-inflatable-escape-slides-modification/documents"}}
