It applies to Beechcraft 56TC (Turbo Baron) series aeroplanes and is labelled AD/BEECH 56/2 Amdt 2, titled \"Elevator Trim Tab System\" (6/75).\n- The AD makes a specific maintenance/inspection requirement mandatory by directing operators to carry out the actions set out in Beechcraft Service Instruction No. 0610-152, Revision 2. The AD text states: \"Action in accordance with Beechcraft SI No. 0610-152, Rev. 2.\" (Requirement).\n- Applicability is limited to the aircraft models listed in the Requirement document (the Service Instruction or associated Requirement Document). The AD records: \"Applicability: All models as listed in Requirement document.\" (Applicability).\n- The timing and particulars of compliance are whatever is specified in the Requirement Document: \"Compliance: As detailed in the Requirement Document.\" (Compliance).\n\n**Who this affects**\n\n- Owners and operators of the Beechcraft 56TC (Turbo Baron) series identified in the Requirement document. (Applicability)\n- Maintenance organisations, licensed engineers and technicians who must perform the actions required by the referenced Beechcraft Service Instruction. (Requirement)\n- The Civil Aviation Safety Authority (CASA) as the issuing authority responsible for mandating and enforcing the AD (header: Civil Aviation Safety Authority Schedule of Airworthiness Directives).\n\n**Why it matters (practical implications and mechanics)**\n\n- By mandating the actions in Beechcraft SI No. 0610-152, Rev. 2, the AD changes a manufacturer's service instruction into a legal requirement for the affected aeroplanes. (Requirement)\n- Who pays: operators/owners pay for whatever inspections, repairs, parts and labour the Service Instruction requires, and for aircraft downtime while work is done. (Requirement; Compliance)\n- Who decides what must be done: CASA issues the AD, but the technical content and specific steps are those set out in the referenced Beechcraft Service Instruction (the AD delegates technical detail to the manufacturer document). (Requirement)\n- Compliance burden and implementation risk: affected parties must obtain the Requirement Document/Service Instruction (Beecraft SI No. 0610-152, Rev. 2), interpret it correctly, schedule and perform the work, and retain evidence of compliance. The AD text does not list the exact tasks or times; those are contained in the referenced document. (Applicability; Requirement; Compliance)\n\n**Trade-offs, incentives and likely operational effects (source-grounded)**\n\n- The AD imposes a mandatory action that creates a direct cost and operational disruption for the identified aircraft owners/operators because the AD converts the manufacturer instruction into a regulatory obligation. (Requirement; Compliance)\n- The technical specification and scope of the mandated action are set by the manufacturer document (Beecraft SI No. 0610-152, Rev. 2). That concentrates technical decision-making in the Service Instruction while enforcement and legal force rest with CASA's AD. (Requirement)\n- The short text of the AD requires affected parties to consult the Requirement Document for details; this adds administrative steps (obtaining and following the SI) and may create uncertainty until that document is examined. (Applicability; Requirement; Compliance)\n\n**Source citations**\n\n- Header: \"COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY SCHEDULE OF AIRWORTHINESS DIRECTIVES.\"\n- Applicability: \"All models as listed in Requirement document.\" (Applicability)\n- Requirement: \"Action in accordance with Beechcraft SI No. 0610-152, Rev. 2.\" (Requirement)\n- Compliance: \"As detailed in the Requirement Document.\" (Compliance)\n\nNote: The text supplied is the AD itself and references an external Requirement Document/Service Instruction for substantive detail. The AD text provided does not include the Service Instruction content, the specific tasks, compliance times, or an explanatory memorandum; those details must be read in Beechcraft SI No. 0610-152, Rev. 2 and the Requirement Document named in the AD."},"kimi_summary":{"content_quality":"ok","complexity_score":2,"scope_assessment":{"changed":false,"description":"This is Amendment 2 to an existing Airworthiness Directive, but the scope remains tightly focused on the elevator trim tab system for the specified aircraft series.

Non-compliance grounds the aircraft (it's illegal to fly until fixed)."}},"importantCases":[],"_links":{"self":"/api/acts/ad-beech-56-2-amdt-2-elevator-trim-tab-system","history":"/api/acts/ad-beech-56-2-amdt-2-elevator-trim-tab-system/history","analysis":"/api/acts/ad-beech-56-2-amdt-2-elevator-trim-tab-system/analysis","conflicts":"/api/acts/ad-beech-56-2-amdt-2-elevator-trim-tab-system/conflicts","importantCases":"/api/acts/ad-beech-56-2-amdt-2-elevator-trim-tab-system/important-cases","documents":"/api/acts/ad-beech-56-2-amdt-2-elevator-trim-tab-system/documents"}}
