The work is to be carried out in accordance with the referenced service document (AMD SB BA F10-0148 R2 (F10-25-009)). (See: \"AD/AMD 10/6 Pilot Seats Actuator End Fitting - Modification\" and \"Document: AMD SB BA F10-0148 R2. (F10-25-009).\")\n\nWho is affected\n\n- Every aircraft of the listed model that has a pilot or co‑pilot seat with serial numbers 1 to 122 must comply. (See: \"Applicability: All models with pilot or co-pilot seats S/Nos. 1 to 122.\")\n\nWhen it must be done\n\n- The modification must be completed within 100 hours time in service after 28 February 1978. (See: \"Compliance: Within 100 hours time in service after 28 February 1978.\")\n\nWhy the directive exists (what the document claims)\n\n- The directive’s title identifies the subject as the pilot seats actuator end fitting and prescribes a modification. The text does not include an explicit statement of the safety problem or incident history in this excerpt; the service document named is the technical source for the modification steps. (See: title and document reference.)\n\nPractical implications, incentives and trade‑offs\n\n- Who pays: Aircraft owners/operators of the affected serial numbers will bear the direct cost of inspecting and modifying the seat actuator end fitting and any associated downtime or parts/labour costs. (Affected group identified in \"Applicability\".)\n\n- Who decides/how: The Civil Aviation Safety Authority issued the directive; compliance is mandatory for the identified aircraft. The detailed technical requirements are set out in the referenced service bulletin, which technicians will follow. (See: AD title and document reference.)\n\n- Compliance burden and timing: Operators must schedule the work within the stated 100 hours time in service after 28 February 1978. That creates a short window measured in flight hours rather than calendar time; operators close to that threshold must plan maintenance accordingly. (See: \"Compliance\".)\n\n- Discretion and implementation risk: The directive itself leaves technical discretion to the service bulletin and to maintenance providers executing that bulletin. Practical risks include availability of parts, access to qualified maintenance resources, and aircraft downtime while the modification is performed. (See: document reference for technical instructions.)\n\n- Effects on private choice and markets: The requirement constrains owners/operators to perform the specified modification rather than choose alternative fixes. Maintenance providers and parts suppliers consistent with the service bulletin may see concentrated demand from the affected serial number group. (Applicability and document reference.)\n\n- Costs versus benefits: The directive imposes a concentrated, identifiable cost on the owners/operators of serial numbers 1–122. The text here does not quantify benefits; the title and mandatory nature imply the regulator judges the modification necessary. The detailed benefit assessment (for example, risk reduced or failure modes addressed) would be found in the service bulletin or accompanying safety analysis, which are not reproduced in this excerpt. (See: title and document reference.)\n\n- Substitution and unintended consequences: The directive prescribes a specific modification; it does not provide alternative compliance paths in the excerpt. Unintended consequences could include grounding delays or parts shortages, depending on fleet size and maintenance capacity; these are practical implementation risks rather than stated outcomes in the text. (See: compliance timing and applicability.)"}},"importantCases":[],"_links":{"self":"/api/acts/ad-amd-10-6-pilot-seats-actuator-end-fitting-modification","history":"/api/acts/ad-amd-10-6-pilot-seats-actuator-end-fitting-modification/history","analysis":"/api/acts/ad-amd-10-6-pilot-seats-actuator-end-fitting-modification/analysis","conflicts":"/api/acts/ad-amd-10-6-pilot-seats-actuator-end-fitting-modification/conflicts","importantCases":"/api/acts/ad-amd-10-6-pilot-seats-actuator-end-fitting-modification/important-cases","documents":"/api/acts/ad-amd-10-6-pilot-seats-actuator-end-fitting-modification/documents"}}
