The inspection/modification must be carried out in accordance with the referenced maintenance/service document AMD SB BA F10-0143 R1 (F10-25-008). (Document; Applicability)\n- Sets a firm compliance window: the work must be completed within 300 hours time in service after 31 March 1980. (Compliance)\n\nWho is directly affected\n\n- Owners and operators of Falcon 10 series aeroplanes with serial numbers 1–104 except S/Ns 50, 91, 93, 98, 101 and 103 are required to comply. (Applicability)\n- Maintenance organisations or certificated mechanics who perform the inspection and any modification under the referenced service document are also involved. (Document)\n\nWhy it matters (the hazard and the regulatory response)\n\n- The background states the safety concern: locking spigots in the seat lock mechanism may jam in the high position and/or may not penetrate the seat rail far enough when locked to resist high loads. The inspection/modification requirement is prescribed to address that risk. (Background)\n\nWho pays, who decides, and what changes in behaviour\n\n- Who pays: The directive obliges owners/operators of the affected aircraft to have the inspection and any required modification carried out within the stated time. The instrument itself does not allocate funding; therefore operators will bear the direct costs of labour, parts and downtime necessary to meet the requirement. (Applicability; Compliance)\n- Who decides: The Civil Aviation Safety Authority issued the directive (this is an Airworthiness Directive entry). The technical work to meet the directive is specified by the referenced service bulletin, which sets the procedures that maintenance providers must follow. (Document)\n- Behaviour changes required: Operators must schedule and record the mandated inspection and any modification, acquire the referenced service instructions, and use qualified maintenance personnel to carry out the work within the 300-hour window. Aircraft that have not completed the work by the compliance time must be brought into compliance before continued operation inconsistent with the directive (implicit in the compliance requirement). (Compliance; Document)\n\nPractical trade-offs, compliance burdens and implementation points to note\n\n- Compliance is time-limited and measured in flight hours (300 hours TIS), so operators must track hours and plan maintenance within that metric rather than a calendar date. This creates a planning and scheduling burden tied to aircraft utilisation. (Compliance)\n- The directive references an external service document for technical steps. Meeting the AD therefore requires access to that document, appropriate parts and qualified maintenance capacity; those are concrete cost and logistics items for operators. (Document)\n- The directive targets a subset of serial numbers (exempting several S/Ns), concentrating the requirement (and its costs) on a defined group of aircraft rather than the whole fleet. That narrows who carries the burden. (Applicability)\n- The stated hazard (spigots jamming or insufficient penetration) defines the observable failure modes that inspection/modification must address; the directive is prescriptive about inspection/modification but relies on the service document to define precise actions and pass/fail criteria. (Background; Document)\n\nImplementation risk and discretion\n\n- The directive itself sets the obligation and the compliance time; discretion over the technical method and acceptance criteria is largely delegated to the referenced service bulletin and the maintenance organisation’s judgement when applying those instructions. (Document)\n- If parts or skilled labour are scarce, operators may face delays or increased costs to comply. The instrument does not specify cost relief or exemptions; it specifies the work and the time within which it must be completed.
