(Applicability)\n\n- The inspection must follow the procedures in the manufacturer service bulletin identified in the directive: SIAI Marchetti SB No. 205B47. (Document)\n\nWhen and how often the inspections must happen\n\n- An initial inspection must be completed within 25 hours time in service after 10 November 1977, and then repeated at intervals not exceeding 500 hours time in service. (Compliance)\n\nWho decides and who does the work\n\n- The directive is issued under Commonwealth civil aviation regulations and appears in the Civil Aviation Safety Authority schedule of airworthiness directives. That instrument legally requires the inspections for the aircraft listed. (header)\n\n- The inspections must be carried out by whoever is responsible for complying with the airworthiness directive (typically the aircraft owner or operator and their authorised maintenance provider). The service bulletin sets out the inspection procedure that must be followed. (Applicability; Document)\n\nPractical effects, costs and trade-offs (mechanical, procedural and economic)\n\n- Who pays: the inspection work and any remedial work discovered by the inspection will be borne by the party that carries out compliance (the owner/operator or their maintenance provider), because the directive requires those inspections. (Applicability; Compliance)\n\n- Regulatory decision and discretion: the Civil Aviation Safety Authority issues the directive and prescribes the compliance timing; the directive defers the technical detail to the named manufacturer service bulletin. That shifts technical discretion over exactly what to inspect and how to the service bulletin, while the AD fixes who must comply and when. (header; Document)\n\n- Compliance burden: operators must reprogramme maintenance/flight schedules to allow an initial inspection within a short window (25 hours TIS after the stated date) and recurrent inspections every 500 hours TIS. This creates recurring maintenance workload and record‑keeping obligations. (Compliance)\n\n- Access to instructions: the AD requires following a separate manufacturer document (SB No. 205B47). Compliance therefore depends on access to and implementation of that external document. (Document)\n\n- Effects on private choice and operations: the AD constrains operator choice by mandating inspection timing and procedure reference; operators may need to allocate hangar time, maintenance labour and parts if inspections find defects. (Applicability; Compliance; Document)\n\nPurpose claimed by the directive and how it is implemented\n\n- The directive’s stated subject is the flap control lever and it requires inspections; the document therefore claims the inspection is necessary for continued airworthiness of that component. The AD implements that claim by imposing a legally binding inspection schedule and by directing compliance to a specific manufacturer service bulletin. (title; Document; Compliance)\n\nSummary in one line\n\n- For the listed SIAI Marchetti models with manual flap control, the AD mandates an initial inspection within 25 hours TIS after 10 Nov 1977 and repeat inspections at intervals not exceeding 500 hours TIS, to be performed in accordance with SIAI Marchetti SB No. 205B47.

The inspection must follow the manufacturer's Service Bulletin (SB No. 205B47).\n\n**Who it affects:**\n- All SIAI Marchetti S-205 and S-208 series aircraft with **manual flap controls**\n- Specifically models: S-205/18F, S-205/18R, S205/20F, S-205/20R, and S205/22R\n\n**When to comply:**\n- **First inspection:** Within 25 hours of flying time after 10 November 1977\n- **Repeat inspections:** Every 500 hours of flying time thereafter\n\n**Why it matters:**\nAirworthiness Directives are legally binding safety requirements. If you don't comply, you cannot legally fly the aircraft. This particular AD likely addresses a discovered defect or wear pattern in the flap control mechanism that could affect flight safety if left unchecked."}},"importantCases":[],"_links":{"self":"/api/acts/ad-sm-205-28-flap-control-lever-inspection","history":"/api/acts/ad-sm-205-28-flap-control-lever-inspection/history","analysis":"/api/acts/ad-sm-205-28-flap-control-lever-inspection/analysis","conflicts":"/api/acts/ad-sm-205-28-flap-control-lever-inspection/conflicts","importantCases":"/api/acts/ad-sm-205-28-flap-control-lever-inspection/important-cases","documents":"/api/acts/ad-sm-205-28-flap-control-lever-inspection/documents"}}
