(Applicability)\n\n- **Required action:** Perform an endoscopic inspection to check whether a specific engine-to-fuselage spherical bearing is present, using SB F2000-299 (original issue or a later DGAC-approved revision). If the bearing is missing, remove the engine immediately for repair; that removal must also include removing the front link system assembly. (Requirement)\n\n- **When it must be done (compliance timing):** The AD sets three timing options depending on the engine's landing count at the AD effective date: (Compliance)\n  - If the engine had fewer than 850 landings at the effective date — inspect before 880 further landings.  \n  - If the engine had 850–1000 landings at the effective date — inspect within 1 month and before 1,010 landings.  \n  - If the engine had more than 1,000 landings at the effective date — inspect within 10 landings.  \n  - If the spherical bearing is found missing, the engine must be removed before further flight.\n\n- **Why it exists (stated purpose):** An in-service aircraft was found with this spherical bearing missing; the missing part can compromise the engine mount and therefore aircraft safety. The AD's stated aim is to mandate a check for the bearing via endoscopic inspection. (Background)\n\n**Who pays, who decides, and what behaviour changes**\n\n- Operators/aircraft owners bear the cost and disruption: they must schedule and perform the inspection, and where a bearing is missing they incur repair and engine-removal costs and downtime (Requirement; Compliance).  \n- The Civil Aviation Safety Authority (via the AD) directs the requirement; the inspection method is specified by reference to the manufacturer's SB or later DGAC-approved revision (Requirement).  \n- Behaviour change: operators must either incorporate SB F2000-299 (to remove themselves from applicability) or perform the mandated inspections within the specified windows; if a missing bearing is found, operators must remove the engine and front link assembly for repair and cannot continue flight until fixed.\n\n**Costs, incentives and trade-offs**\n\n- Direct costs: inspection labour and equipment (endoscopy), possible unscheduled engine removal and repair, removal/repair of front link assembly, aircraft downtime, and potential replacement parts and shop visits. These are concentrated on the small group of operators with affected serial-number engines. (Requirement; Compliance)\n- Incentives: operators with affected engines face a clear short-run incentive to inspect quickly and, where possible, to incorporate SB F2000-299 to avoid being subject to future AD action for the same issue (Applicability; Requirement).  \n- Trade-offs: the AD reduces the risk of an in-flight structural failure (benefit) at the cost of inspection and repair expense and operational disruption (cost). The AD imposes no market-wide restrictions (it does not mandate fleet-wide grounding) — its effects are concentrated on a narrow set of serial-numbered engines. (Background; Applicability)\n\n**Implementation risks and compliance burden**\n\n- Technical capacity: endoscopic inspection requires appropriate tools and trained maintenance personnel; some operators may need to outsource the task. (Requirement)\n- Parts and repair capacity: if bearings are missing, lead times for bearings or shop capacity for engine removal/repair could extend aircraft downtime. (Requirement)\n- Administrative burden: operators must track landing counts at the AD effective date to determine the applicable inspection window and document compliance.\n\n**Effects on private enterprise and competition**\n\n- The AD imposes micro-level costs on specific operators; it does not alter ownership, market access, competition rules, or contract freedom beyond normal regulatory oversight of airworthiness.  \n- Maintenance providers and repair shops may see increased short-term demand from the affected subset of aircraft; conversely, affected operators face higher short-term maintenance expenditure.\n\n**Concise takeaway**\n\nThis AD mandates a focused inspection (endoscopic) of a particular engine-to-fuselage spherical bearing on nine identified CFE 738 engines fitted to Falcon 2000 aircraft that have not incorporated SB F2000-299. If the bearing is missing, the engine (and front link system assembly) must be removed and repaired before further flight. The directive concentrates costs and operational disruption on the small group of affected operators while aiming to eliminate a specific safety risk.
