(See \"Requirement\".)\n- The AD applies only to Beechcraft Model 36 and A36 aircraft with serial numbers E-1 through E-201. (See \"Applicability\".)\n- The required action must be done within 100 hours time in service after 31 July 1970. (See \"Compliance\".)\n\nWho it affects\n\n- Aircraft owners and operators of the listed Beechcraft Model 36/A36 aeroplanes (S/N E-1 to E-201) are directly affected because they must arrange and pay for the specified work. (Applicability; Requirement; Compliance.)\n- Maintenance providers engaged by those owners may perform the work if they follow the service instruction called up by the AD. (Requirement.)\n- The Civil Aviation Safety Authority (CASA) or its delegated inspectors are the regulatory decision-makers and enforcers for this AD (document is issued under the Commonwealth Civil Aviation Regulations, Part 39 schedule of Airworthiness Directives).\n\nWhy it matters (stated purpose and practical consequences)\n\n- The AD is titled \"Seat Track Screws,\" and it calls for action in accordance with a specific Beechcraft Service Instruction. Taken together, the document targets a defined maintenance issue involving seat track screws by mandating manufacturer-prescribed work. That stated purpose is contained in the title and the Requirement citation.\n\n- Practical consequences for owners/operators: they must schedule the work within the specified 100-hour window and bear the direct costs (parts, labour, and aircraft downtime) of complying with the service instruction. (Requirement; Compliance.)\n\nAnalytical points about incentives, costs and trade-offs\n\n- Who pays and who decides: Owners/operators pay for the work; CASA issues and enforces the AD. (Applicability; Requirement; Compliance; header.)\n\n- Instruction is external to the AD: the AD delegates the technical details to Beechcraft Service Instruction No. 0343-314. That means the AD's actual burden and technical steps depend on that external document. The AD itself does not list parts, labour hours, or exact procedures — it simply makes compliance with the SI mandatory. (Requirement.)\n\n- Compliance burden and implementation risk: because the AD references an external SI, affected parties must obtain and follow that SI. The SI may require replacement parts, inspections, or repairs; any such needs will create costs and aircraft out-of-service time. The AD does not quantify those costs or times. (Requirement; Compliance.)\n\n- Concentration of costs and benefits: costs fall directly and narrowly on owners/operators of the specified serial-numbered aircraft. Any benefits (the AD purports to address an issue with seat track screws) are concentrated on the same group and on flight safety more broadly; the AD text provides no measurement of those benefits. (Applicability; Requirement.)\n\n- Effects on private choice and the maintenance market: owners must either perform the SI work themselves if they are qualified, or contract a maintenance organisation to do so. This imposes a scheduling constraint (complete within 100 hours after 31 July 1970) and reduces discretion over whether to follow the manufacturer-prescribed steps, because compliance is mandatory under the AD. (Requirement; Compliance.)\n\n- Bureaucratic discretion and enforcement: the AD is issued under the Commonwealth regulations and thus is enforceable by the national aviation regulator; discretion about exemptions or alternative methods would rest with that regulator or its delegated processes (not described in this text). (Header; Requirement.)\n\nNotes on uncertainty and limits of the text\n\n- The AD text provided here does not include the content of Beechcraft SI No. 0343-314, so the specific technical actions, parts required, labour estimate, and the technical justification are not shown. Any precise estimate of cost, downtime, or technical trade-offs requires consulting that Service Instruction.

The exact fix is detailed in a separate Beechcraft Service Instruction (SI No. 0343-314).\n\n**Who it affects:** Anyone who owns, operates, or maintains these specific Beechcraft aircraft in Australia.\n\n**Why it matters:** Seat track screws are critical hardware that secure pilot and passenger seats to the aircraft floor. If these screws fail or are improperly installed, seats could shift or detach during flight — potentially causing loss of aircraft control or serious injury. This AD mandates a safety inspection and repair to prevent that risk.\n\n**The deadline:** The work must be completed within **100 hours of flight time** after 31 July 1970."}},"importantCases":[],"_links":{"self":"/api/acts/ad-beech-36-7-seat-track-screws","history":"/api/acts/ad-beech-36-7-seat-track-screws/history","analysis":"/api/acts/ad-beech-36-7-seat-track-screws/analysis","conflicts":"/api/acts/ad-beech-36-7-seat-track-screws/conflicts","importantCases":"/api/acts/ad-beech-36-7-seat-track-screws/important-cases","documents":"/api/acts/ad-beech-36-7-seat-track-screws/documents"}}
