The AD became effective on 17 January 2001.\n\n**Who this affects**\n\n- Aircraft owners, operators and maintenance organisations responsible for the specified A36 and B36TC aircraft. They must obtain and follow the Raytheon service bulletin and the relevant aircraft maintenance/shop manual to carry out the inspection and any corrective actions (Requirement).\n\n- Maintenance providers who perform the inspection and any repairs will bear labour and parts costs, and operators will bear aircraft downtime while work is done.\n\n**Why it matters (mechanical description)**\n\n- The FAA reported three incidents where rudder control cables were misrouted: routed over guard pins rather than between the pins and pulleys (Background). That misrouting can cause guard-pin wear, separation or cable fraying, which could lead to loss of rudder control.\n\n- This AD directs a one-time inspection (and corrective action as necessary) to identify and fix misrouting before it results in cable damage and potential loss of control.\n\n**How it works in practice — who pays, who decides, what changes**\n\n- Who pays: aircraft owners/operators pay for the inspection, any repairs, replacement parts, and labour; maintenance organisations perform the work under the applicable manuals.\n\n- Who decides: the Civil Aviation Safety Authority (CASA) delegate issued the AD under subregulation 39.1(1) of CAR 1998 and the AD compels compliance by the affected operators (front matter & Requirement).\n\n- Behaviour change required: operators must schedule and complete the specified inspection within the 50-hour window and follow the service bulletin and manuals for remediation if misrouting is found (Compliance & Requirement).\n\n**Costs, incentives and trade-offs**\n\n- Direct costs are inspection labour, potential parts and repairs, and aircraft downtime. Those costs are concentrated on owners/operators of the listed serial-number aircraft.\n\n- The AD relies on a single, short compliance window (50 hours) rather than recurring inspections. That concentrates immediate workload and downtime but avoids an ongoing inspection burden unless the service bulletin specifies repeats.\n\n- The AD cross-references an external manufacturer service bulletin and aircraft manuals. That means operators must obtain and follow those documents precisely; practical complexity arises from possession of and familiarity with those documents (Requirement).\n\n- The AD does not expand to other models or serials; benefits are concentrated on preventing the specific failure mode identified in the Background.\n\n**Implementation risks and practical notes**\n\n- Operators must ensure Raytheon Mandatory Service Bulletin 27-3265 (Jan 2000) and the relevant maintenance/shop manual are followed exactly; incomplete or inconsistent application could reduce the effectiveness of the remedy (Requirement).\n\n- If misrouted cables or wear are found, corrective action prescribed by the bulletin/manual will increase repair costs and downtime. The AD does not itself list repeat-inspection intervals — any such requirement would come from the service bulletin or the maintenance manual.\n\n**Reference points in the AD text**\n\n- Applicability: serial-number limits listed (Applicability).\n- Required action: inspect per Raytheon Mandatory Service Bulletin 27-3265 and the Maintenance/Shop Manual (Requirement).\n- Compliance timeframe: within 50 hours time-in-service after 17 January 2001 (Compliance).\n- Safety reason: reports of misrouted cables and risk of cable wear/separation and loss of rudder control (Background)."},"kimi_summary":{"content_quality":"ok","complexity_score":2,"scope_assessment":{"changed":false,"description":"This is a standard, narrow Airworthiness Directive targeting a specific mechanical defect in specific aircraft.
