It requires specific maintenance action on certain Beechcraft Queen Air models to address a flight controls issue. (See header and Requirement.)\n\nWho it affects\n\n- Aircraft owners/operators of the affected Queen Air models: all model Queen Air B80 with serial numbers LD-441 to LD-511; 70 series with serial numbers LB-31 through LB-35; and all 65, 65-80, 70 and 80 series that were fitted with a rudder shipped from Beech between 1 May 1973 and 1 July 1976. (Applicability.)\n\nWhat must be done and by when\n\n- Operators must carry out the work described in Beechcraft Service Instruction No. 0629-150, Revision 11. (Requirement.)\n- If the work has not already been done, it must be completed within 100 hours time in service after 31 January 1979. (Compliance.)\n\nWho decides and who pays\n\n- The Civil Aviation Safety Authority (CASA) issues the directive and sets the requirement and deadline. (header and Compliance.)\n- The operator or owner of the affected aeroplane is required to have the action performed; they will be responsible for arranging and paying for the inspection/maintenance and any parts or labour needed to meet the Service Instruction. (Applicability, Requirement, Compliance.)\n\nWhy it matters (official claim and operational implications)\n\n- The directive requires a mandated maintenance action stated in a manufacturer Service Instruction. The document labels this action under the topic “Flight Controls” and consolidates coverage for Queen Air series 65 and 70 aircraft. (Requirement; Background.)\n- Mechanically, the AD delegates the technical details to the Beechcraft Service Instruction. That means the AD itself sets the legal obligation and timetable, while the SI contains the step-by-step technical work operators must follow. (Requirement.)\n\nImplementation and compliance considerations\n\n- Compliance depends on access to Beechcraft SI No. 0629-150 Rev. 11. The AD does not reproduce technical steps or parts lists, so operators must obtain and follow the SI. (Requirement.)\n- The AD prescribes a fixed compliance window (100 hours TIS after 31 January 1979). Operators must plan maintenance to meet that window and bear any downtime and direct costs. (Compliance.)\n- Amendment 3 is described as consolidating Queen Air 65 and 70 series coverage, which changes which airframes are captured by the directive compared with earlier drafts. (Background.)\n\nTrade-offs, incentives and risks (mechanics, not judgement)\n\n- The directive creates an obligation that transfers cost and scheduling responsibility to aircraft operators: they pay for and arrange the required work. (Requirement, Compliance.)\n- Because the AD refers to an external Service Instruction for technical detail, compliance requires obtaining that manufacturer document and following it exactly; this concentrates technical discretion in the SI rather than in the AD text. (Requirement.)\n- The consolidation noted in the Background expands or clarifies the set of affected aircraft; operators should check the exact serial-number and rudder-shipment criteria to determine applicability.

Flight control failures can be catastrophic. The \"Amendment 3\" note indicates this version consolidates earlier separate directives for the 65 and 70 series into one document, making compliance simpler.\n\n**Key takeaway:** If you owned one of these planes in 1979, you legally had to get this rudder inspection done within your next 100 flying hours or face grounding."}},"importantCases":[],"_links":{"self":"/api/acts/ad-beech-65-40-amdt-3-flight-controls","history":"/api/acts/ad-beech-65-40-amdt-3-flight-controls/history","analysis":"/api/acts/ad-beech-65-40-amdt-3-flight-controls/analysis","conflicts":"/api/acts/ad-beech-65-40-amdt-3-flight-controls/conflicts","importantCases":"/api/acts/ad-beech-65-40-amdt-3-flight-controls/important-cases","documents":"/api/acts/ad-beech-65-40-amdt-3-flight-controls/documents"}}
