The directive does not reproduce technical steps; it points to that Service Instruction for the detailed procedure. (Requirement)\n\n- Who is affected: All Model 200 aeroplanes with serial numbers BB-6 to BB-87, BB-89 to BB-99 and BB-101 to BB-106; and all Model A200 aeroplanes with serial numbers BC-1 to BC-8 and BD-1 to BD-8. In practice this affects the registered owners/operators of those specific airframes and any maintenance organisations they use. (Applicability)\n\n- When it must be done: The required work must be completed within 100 hours time in service after 31 May 1976. (Compliance)\n\n- Cross-references: The directive explicitly refers users to Beechcraft Service Instruction No 0789-314 for the technical action, and notes that FAA AD 76-04-02 is relevant. Those references are placed by the directive rather than containing the technical detail within the directive itself. (Requirement, Note)\n\nWho pays and who decides\n- Who pays: The owners/operators of the specified aircraft will bear the direct costs of complying — labour, parts, and any grounding/downtime while the work is done. (Applicability; Requirement; Compliance)\n- Who decides: The Civil Aviation Safety Authority issued the directive as a regulatory requirement; the detailed technical method is delegated to the Beechcraft Service Instruction referenced by the directive. An owner/operator can choose which qualified maintenance organisation carries out the work, subject to regulatory approvals for maintenance work. (Schedule header; Requirement)\n\nIncentives, trade-offs and implementation notes\n- Incentives and costs: The directive creates a compliance obligation that shifts costs (parts, labour, downtime) onto affected operators. It also creates demand for maintenance services and any parts specified in the Service Instruction. (Applicability; Requirement)\n- Compliance burden and discretion: The directive sets a mandatory deadline and refers to a separate Service Instruction for technical detail. That referral lowers the directive's technical complexity but requires access to the Service Instruction and competent maintenance personnel. Enforcement discretion (scheduling, approvals) remains with the regulator and authorised maintenance organisations. (Requirement; Compliance)\n- Opportunity costs and operational impact: Operators must allocate aircraft time to perform the mandated action within the 100‑hour window, which can reduce available flight hours and potentially affect revenue or scheduling until the work is completed. (Compliance)\n- Concentration of costs and benefits: Costs are concentrated on owners/operators of the specified serial-numbered aeroplanes; any safety or technical benefit claimed by the regulator or by the FAA cross-reference is asserted via the referenced FAA AD and Service Instruction rather than set out in this document. (Applicability; Note)\n\nWhat this document does not do\n- It does not list the technical steps, the parts needed, the estimated cost, or the specific safety justification; those details are left to Beechcraft Service Instruction No 0789-314 and the referenced FAA AD. (Requirement; Note)\n\nSummary statement: The directive is a narrowly targeted regulatory order requiring specified Beechcraft Model 200/A200 aircraft to undergo the action described in a particular Beechcraft Service Instruction within a fixed period; owners/operators must arrange and pay for the work, and compliance depends on obtaining and following the referenced Service Instruction and meeting the 100‑hour deadline.

The exact fix is detailed in a Beechcraft Service Instruction (SI No 0789-314), which operators must follow.\n\n**Who it affects:** This applies only to specific serial numbers of:\n- **Model 200:** Serial numbers BB-6 through BB-87, BB-89 through BB-99, and BB-101 through BB-106\n- **Model A200:** Serial numbers BC-1 through BC-8 and BD-1 through BD-8\n\n**Why it matters:** Faulty seat locking pins could allow seats to move unexpectedly during flight — a serious safety risk. This directive ensures a known defect gets fixed before it causes an accident.\n\n**When it had to be done:** Operators had to complete this work within 100 hours of flight time after 31 May 1976.
