It applies to Beechcraft 95 (Travelair) aeroplanes of models D95A and E95A with serial numbers TD-534 to TD-721 that are fitted with Goodyear BTC-39 fuel cells. (Applicability)\n\n- The directive requires the operator or owner to carry out the action set out in Beechcraft Service Instruction No. 0895 (\"Beecraft SI No. 0895\"). The AD does not reproduce the specific steps; it makes compliance with that service instruction mandatory. (Requirement)\n\n- Timing: the required action must be done within 100 hours time-in-service after 30 June 1978, and then repeated at intervals not exceeding 12 months. (Compliance)\n\nWho decides and who pays\n\n- The Civil Aviation Safety Authority (under the Civil Aviation Regulations Part 39 framework) issues the directive and makes compliance mandatory. (header and instrument type)\n\n- The owner or operator of any affected aircraft is the party required to perform the mandated action and therefore will bear the direct costs of carrying out the service instruction (labour, parts, any downtime). (Applicability; Requirement; Compliance)\n\nWhat behaviour changes\n\n- Operators of the identified aircraft must schedule and carry out whatever inspection, modification or repair is detailed in Beechcraft SI No. 0895 within the specified initial and recurring time limits. Failure to comply would leave the aircraft non-compliant with the AD and expose the operator to regulatory enforcement.\n\nPurpose claim and practical trade-offs (source-grounded)\n\n- The AD text itself does not state the specific safety defect or incident that prompted it; it instead mandates the manufacturer's service instruction for the named fuel cells. The operative effect is to require maintenance action on Goodyear BTC-39 fuel cells fitted to the listed aircraft. (Requirement)\n\n- Practical trade-offs and incentives that flow from that effect: operators incur routine and recurring maintenance cost and downtime to follow the service instruction; maintenance organisations and parts suppliers gain demand for work and components; operators gain regulatory compliance and, implicitly, whatever airworthiness outcome the service instruction is intended to achieve. These are mechanical consequences of mandating a manufacturer instruction as law—the directive converts a manufacturer recommendation into a legally enforceable requirement. (Requirement; Compliance)\n\nImplementation, discretion and compliance burden\n\n- The AD delegates the technical details of what must be done to Beechcraft SI No. 0895; consequentially, the precise scope of work, parts needed, and labour hours are determined by that external document rather than by the text of the AD itself. That creates a dependency on the manufacturer service instruction for implementation. (Requirement)\n\n- The prescriptive timing (initial within 100 hours after 30 June 1978, then at intervals of no more than 12 months) creates a recurring compliance burden for affected aircraft owners/operators. (Compliance)\n\nConcentrated and diffuse effects\n\n- The directive targets a narrowly defined set of aircraft by model, serial number range, and specific fuel cell type. That concentrates compliance obligations and costs on a limited group of aircraft owners/operators while creating ongoing work for maintenance providers who serve those aircraft. (Applicability; Requirement; Compliance)\n\nReferences to the source text\n\n- Applicability: \"Models D95A and E95A with S/Nos TD-534 to TD-721, fitted with Goodyear BTC-39 fuel cells.\" (Applicability)\n- Requirement: \"Action in accordance with Beechcraft SI No. 0895.\" (Requirement)\n- Compliance timing: \"Within 100 hours’ time in service after 30 June 1978 and thereafter at intervals not exceeding twelve months.\" (Compliance)\n\nSummary statement\n\n- Mechanically, this AD converts the Beechcraft service instruction on Goodyear BTC-39 fuel cells into a mandatory, recurring maintenance requirement for a specific set of Beechcraft 95 aeroplanes. The owner/operator is the party responsible for carrying out and paying for the required action; CASA is the issuing authority that makes the instruction compulsory. The AD relies on the external service instruction for technical details and sets a fixed initial and recurring compliance schedule."},"kimi_summary":{"content_quality":"ok","complexity_score":2,"scope_assessment":{"changed":false,"description":"This is a discrete, targeted safety directive addressing a specific known defect in specific aircraft.

Think of it like a compulsory recall notice, but for aircraft parts.\n\n**What it does:** It requires owners or operators of specific Beechcraft 95 \"Travelair\" planes (models D95A and E95A, serial numbers TD-534 to TD-721) to inspect or replace their Goodyear BTC-39 fuel cells. The work must follow Beechcraft's Service Instruction No. 0895.\n\n**Who it affects:** Anyone who owns, operates, or maintains these specific Beechcraft twin-engine aircraft fitted with these particular fuel cells (the rubberized bags inside fuel tanks that hold the fuel).\n\n**Why it matters:** Fuel cells can degrade, leak, or fail over time. A leaking fuel cell creates fire and explosion risks. This directive ensures these specific fuel cells are checked regularly to prevent catastrophic failures.\n\n**The requirements:**\n- **First check:** Must be done within 100 flight hours after 30 June 1978\n- **Ongoing checks:** Must be repeated at least every 12 months thereafter\n\n**Key point:** This is not optional. Non-compliance means the aircraft cannot legally fly in Australian airspace."}},"importantCases":[],"_links":{"self":"/api/acts/ad-beech-95-19-goodyear-fuel-cells","history":"/api/acts/ad-beech-95-19-goodyear-fuel-cells/history","analysis":"/api/acts/ad-beech-95-19-goodyear-fuel-cells/analysis","conflicts":"/api/acts/ad-beech-95-19-goodyear-fuel-cells/conflicts","importantCases":"/api/acts/ad-beech-95-19-goodyear-fuel-cells/important-cases","documents":"/api/acts/ad-beech-95-19-goodyear-fuel-cells/documents"}}
