(See heading and title: \"AD/AMD 10/9 Landing Gear Uplatch Boxes - Installation\".)\n- The AD applies only to Falcon 10 aeroplanes with serial numbers 1 to 127. (See: \"Applicability: Falcon 10 aeroplanes with S/Nos. 1 to 127.\")\n- The work must be completed by a fixed deadline: before 30 September 1979. (See: \"Compliance: Before 30 September 1979.\")\n- The AD points to a specific technical instruction for how to carry out the installation: \"AMD SB BA F10-0157 R2. (F10-32-019).\" (See: \"Document: AMD SB BA F10-0157 R2. (F10-32-019).\")\n\nWho is affected and who decides\n\n- The persons who must comply are the operators or owners of Falcon 10 aeroplanes with serial numbers 1–127 (the document lists those aircraft under \"Applicability\").\n- The Civil Aviation Safety Authority (as the issuing authority listed at the top of the document) is the body that issued this AD and set the deadline and requirements.\n- The referenced service bulletin (AMD SB BA F10-0157 R2) is the procedural source that prescribes how the installation is to be done; compliance requires following that document.\n\nWhy it matters (stated and implied claims)\n\n- The AD requires a specific modification (installation of landing gear uplatch boxes) on a defined set of aircraft by a set date. The text does not state a detailed reason or safety analysis within the excerpt supplied; it simply mandates the installation and cites the technical document to implement it.\n\nTesting the stated/implicit purpose against costs, incentives and practical effects\n\n- Who pays: The direct cost of parts and labour to carry out the installation will fall on the owners/operators of the listed Falcon 10 aircraft (inference drawn from the AD applying to those aircraft and requiring compliance). (See: \"Applicability\" and \"Compliance\".)\n- Compliance burden and opportunity cost: Aircraft will need to be taken into maintenance to install the uplatch boxes, which consumes technician time and aircraft downtime until the work is completed by the compliance date. (Inferred from the requirement to install a component and the deadline in \"Compliance\").\n- Implementation details and administrative discretion: The AD points to a specific service bulletin for how to perform the work (\"Document: AMD SB BA F10-0157 R2\"). That bulletin is the technical instruction; the AD itself does not set alternative methods or exemption criteria in the supplied text. The AD excerpt does not state any mechanism for approvals, variations, or time extensions, nor does it list penalties or enforcement measures. (See: \"Document\" and lack of additional procedural text in the excerpt.)\n- Effects on related businesses: Maintenance organisations that perform the installation will receive the work; parts suppliers will provide the uplatch boxes. Those economic effects are a direct mechanical consequence of prescribing an installation.\n- Concentration of costs and benefits: Costs are concentrated on the relatively small set of owners/operators of Falcon 10s with S/N 1–127. The directive’s benefits (not described in the excerpt) would accrue to those who value the outcome of the installation; the text supplied does not quantify or describe those benefits.\n- Unstated risks and trade-offs: The document does not describe risks of non-compliance, nor does it provide alternatives, staged compliance, or exemptions in the supplied excerpt. Any operational impacts, such as temporary grounding or schedule disruption while work is done, are a foreseeable trade-off but are not described in the text.\n\nKey textual references\n\n- Issuing authority and schedule header: \"COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY SCHEDULE OF AIRWORTHINESS DIRECTIVES\"\n- Title: \"AD/AMD 10/9 Landing Gear Uplatch Boxes - Installation 11/78\"\n- Applicability: \"Falcon 10 aeroplanes with S/Nos. 1 to 127.\"\n- Document reference: \"AMD SB BA F10-0157 R2. (F10-32-019).\"\n- Compliance deadline: \"Before 30 September 1979.\"\n\nLimitations of this summary\n\n- The supplied excerpt does not include an explicit statement of the safety problem being addressed, any cost estimates, enforcement provisions, or any procedural paths for alternative compliance. The summary therefore describes the mechanical requirement, the affected population, and the observable compliance mechanics only from the provided text."}},"importantCases":[],"_links":{"self":"/api/acts/ad-amd-10-9-landing-gear-uplatch-boxes-installation","history":"/api/acts/ad-amd-10-9-landing-gear-uplatch-boxes-installation/history","analysis":"/api/acts/ad-amd-10-9-landing-gear-uplatch-boxes-installation/analysis","conflicts":"/api/acts/ad-amd-10-9-landing-gear-uplatch-boxes-installation/conflicts","importantCases":"/api/acts/ad-amd-10-9-landing-gear-uplatch-boxes-installation/important-cases","documents":"/api/acts/ad-amd-10-9-landing-gear-uplatch-boxes-installation/documents"}}
