(Requirement)\n- The directive applies to Garrett AiResearch starters installed in, but not limited to, Boeing Models 707, 727 and 737 and McDonnell Douglas Models DC-9, DC-10 and DC-8. (Applicability)\n- The directive became effective on 4 March 1993; operators must comply from that date. (Compliance)\n\n### Who is affected\n- Aircraft operators, maintenance organisations and owners that have the listed Garrett AiResearch starters on the specified aircraft types (Applicability).\n- Aircraft certificate of registration holders who receive the distributed FAA AD listing the affected part and serial numbers. (Background)\n\n### Why it matters (stated reason and mechanical effect)\n- The Background states that improperly overhauled starters with unauthorised repairs were distributed by Classic Aircraft Aviation (USA) and that these starters can suffer uncontained turbine wheel failures, creating a risk of fire or loss of control. (Background)\n- Mechanically, the directive makes compliance with the FAA AD mandatory in Australia: it requires the inspections, removals, repairs or replacements and any other technical steps specified in FAA AD 92-16-06. (Requirement)\n\n### Who pays and who decides\n- Aircraft operators and their maintenance providers bear the direct costs of inspections, repairs, replacements, and aircraft downtime required to meet the FAA AD technical requirements. (Requirement; Compliance)\n- The Civil Aviation Safety Authority (CASA) enforces this directive by issuing the schedule of airworthiness directives and distributing the FAA AD and relevant part/serial number lists to certificate holders. (Applicability; Background)\n\n### Incentives, compliance burden and implementation risks\n- Incentives: Operators have a safety and regulatory incentive to replace or repair affected starters per the FAA AD rather than continue using potentially unsafe, unauthorised-overhaul units. (Background; Requirement)\n- Compliance burden: Operators must locate affected starters (using part and serial number lists distributed with the directive), schedule inspections or removals, and absorb associated labour, parts and downtime costs. The directive references an external technical document (FAA AD 92-16-06), which operators must obtain and follow. (Background; Requirement)\n- Implementation risks and trade-offs: If replacement parts or authorised overhaul services are scarce, operators may face increased grounded time or higher costs to source compliant units. Making the FAA AD mandatory shifts decision-making on technical remedies to the FAA-specified solutions until CASA or an Australian technical equivalent is issued. (Requirement; Compliance)\n\n### Concrete mechanics and scope notes\n- The directive does not itself list parts/serial numbers in the text shown; instead, it requires compliance with the FAA AD and states that copies of the FAA AD listing relevant part and serial numbers are being distributed to certificate of registration holders of affected aircraft types. Operators must consult that material to identify affected units. (Requirement; Background)\n\nOverall, the instrument converts the FAA AD’s technical requirements into an Australian mandatory safety requirement for the listed aircraft types, creating immediate compliance obligations for operators to inspect, remove, repair or replace affected Garrett starters and bear the associated costs and operational impacts.
