It requires operators to carry out the work specified in Beechcraft Service Instruction No. 0497-155 (Requirement).\n\n- The work must be done within 25 hours of flying time after 10 May 1972, and then repeated at intervals not exceeding 500 hours of flying time (Compliance), unless a specific replacement adapter (part number 99-524036-33) is fitted. Once adapter P/N 99-524036-33 is installed, the recurring 500-hour interval requirement no longer applies (Compliance).\n\nWho is affected and who decides:\n\n- Aircraft owners and operators of Queen Air 65 and 70 models are required to comply (Applicability).\n\n- The Civil Aviation Safety Authority issues the AD and points operators to the Beechcraft Service Instruction as the method of compliance (Requirement).\n\nWho pays and what they must do:\n\n- Owners/operators bear the direct costs of performing the required actions under the referenced Beechcraft Service Instruction, and the costs of parts and labour to fit adapter P/N 99-524036-33 if they choose that route to remove the recurring requirement (Requirement; Compliance).\n\n- Practically, operators must either perform the specified action and repeat it every up to 500 hours of service, or install the identified adapter part number to end the recurring work (Compliance).\n\nWhy it matters (mechanics, incentives and trade-offs):\n\n- Mechanically, the AD mandates a specific maintenance action and a compliance schedule tied to flight hours (Requirement; Compliance). It relies on a manufacturer-issued service instruction for the technical steps (Requirement).\n\n- The AD creates a recurring maintenance burden (500-hour intervals) until a defined part is installed, which gives owners a clear trade-off: incur repeated inspection/maintenance costs or incur a one-time cost to fit the specified adapter part to stop the repeated requirement (Compliance).\n\n- The AD centralises the method of compliance by referring to the manufacturer Service Instruction, which concentrates technical discretion with the maker of that instruction and with the approved maintenance organisations that implement it (Requirement).\n\nNotes on scope and change:\n\n- The document is presented as Amendment 1 and notes that the amendment \"consolidates Queen Air series 65 and 70 aircraft\" (Background). That means the AD as amended covers both series together under this single directive, rather than treating them separately (Background).\n\nRelevant text citations: Applicability; Requirement (Beechcraft SI No 0497-155); Compliance (25 hours after 10 May 1972, then at intervals not exceeding 500 hours until adapter P/N 99-524036-33 is installed); Background (Amendment 1 consolidates series 65 and 70)."},"kimi_summary":{"content_quality":"ok","complexity_score":2,"scope_assessment":{"changed":false,"description":"This AD remains tightly focused on its original purpose: ensuring the airworthiness of control wheel adapters on specific Beechcraft aircraft.

Think of it like a compulsory recall notice, but for aircraft rather than cars.\n\n**What it does:** It requires owners and operators of specific Beechcraft aeroplanes (the Queen Air 65 and 70 series) to inspect or modify the **control wheel adapter** — a component that connects the pilot's steering wheel (yoke) to the aircraft's control systems.\n\n**Who must follow it:** Anyone who owns or operates a Beechcraft Queen Air model 65 or 70.\n\n**What they must do:**\n- Follow the instructions in **Beechcraft Service Instruction No. 0497-155** (the manufacturer's official repair/inspection guide)\n- Complete the first inspection within **25 flight hours** after 10 May 1972\n- Repeat the inspection every **500 flight hours** thereafter\n- Keep doing this until a specific replacement part (adapter P/N 99-524036-33) is installed\n\n**Why it matters:** Control wheel adapters are critical safety components. If they fail, the pilot could lose control of the aircraft. This AD ensures potential defects are caught before they cause accidents.\n\n**What changed in this version:** Amendment 1 simply combined the requirements for both the 65 and 70 series into one directive, rather than having separate rules for each model."}},"importantCases":[],"_links":{"self":"/api/acts/ad-beech-65-31-amdt-1-control-wheel-adapter","history":"/api/acts/ad-beech-65-31-amdt-1-control-wheel-adapter/history","analysis":"/api/acts/ad-beech-65-31-amdt-1-control-wheel-adapter/analysis","conflicts":"/api/acts/ad-beech-65-31-amdt-1-control-wheel-adapter/conflicts","importantCases":"/api/acts/ad-beech-65-31-amdt-1-control-wheel-adapter/important-cases","documents":"/api/acts/ad-beech-65-31-amdt-1-control-wheel-adapter/documents"}}
