This creates fire hazards and could leave the aircraft without enough fuel for flight.\n\n**What must be done:**\nInstall physical stops on the fuel selector valve to prevent it being moved to the problematic position. This must be done following the manufacturer's instructions in **Fuji Service Bulletin No. 200-007**.\n\n**Deadline:**\nComplete the modification within **100 hours of flight time** after 31 December 1986, unless already done.\n\n**Why it matters:**\nFuel leaks create serious fire risks and can cause engine failure due to fuel starvation. This directive forces a simple mechanical fix (adding stops to prevent wrong valve positions) to eliminate a known design flaw."},"flash_summary":{"complexity_score":2,"scope_assessment":{"changed":false,"description":"The directive's scope is limited to Fuji FA-200 aircraft with serial numbers 101 and later and earlier aircraft that have Service Bulletin FAS-032 incorporated (Applicability). It prescribes a specific mechanical modification (replacement/installation and stops) to address fuel loss via the vent system when the selector is in a prohibited position, to be completed per Fuji Service Bulletin No. 200-007 within a fixed compliance window (Requirement; Background; Compliance). There is no indication in the text that the scope was expanded or altered from that stated purpose."},"complexity_factors":["Narrow applicability tied to specific serial numbers and prior incorporation of Service Bulletin FAS-032 (Applicability).","Mandated action is to follow a single external technical document (Fuji Service Bulletin No. 200-007), creating a dependency on that document (Requirement).","A fixed compliance window (100 hours time in service after 31 December 1986) imposes scheduling constraints on operators (Compliance).","Technical installation requires qualified maintenance but the AD does not itself set installation detail beyond referring to the Service Bulletin (Requirement).","Reference to an equivalent foreign authority document (Japan Civil Aviation Bureau AD No. TCD-2598-86) for context, though the AD relies on the Service Bulletin for technical steps."],"plain_english_summary":"The directive requires affected Fuji FA‑200 aeroplanes (serial no. 101 onward, and earlier ones with SB FAS‑032) to have the fuel shut‑off valve replaced by a fuel‑selector with physical stops fitted so the “prohibited” position cannot be selected, by following Fuji Service Bulletin No. 200‑007. Owners/operators must arrange, pay for and record the modification. It matters because the change prevents fuel loss via the vent system during parking by removing a pilot/ground‑crew error source and imposing a mechanical safety control."}},"importantCases":[],"_links":{"self":"/api/acts/ad-fa-200-22-fuel-selector-valve","history":"/api/acts/ad-fa-200-22-fuel-selector-valve/history","analysis":"/api/acts/ad-fa-200-22-fuel-selector-valve/analysis","conflicts":"/api/acts/ad-fa-200-22-fuel-selector-valve/conflicts","importantCases":"/api/acts/ad-fa-200-22-fuel-selector-valve/important-cases","documents":"/api/acts/ad-fa-200-22-fuel-selector-valve/documents"}}
