It requires aircraft operators to follow the manufacturer's Service Bulletin No. 657 when replacing or inspecting fire extinguisher squibs (small explosive charges that trigger fire extinguishers).\n\n**Who it affects:** Owners and operators of AMD Fan Jet Falcon, Falcon 20, and Mystere-Falcon 200 series aircraft (all models).\n\n**Why it matters:** A design change meant newer squibs no longer require a spacer washer. However, a safety incident revealed that if mechanics mistakenly install the old spacer with the new squib design, the fire bottle won't activate during an emergency. This rule prevents that potentially fatal error by ensuring mechanics follow the correct installation procedure."}},"importantCases":[],"_links":{"self":"/api/acts/ad-amd-20-17-fire-extinguisher-bottle-squib","history":"/api/acts/ad-amd-20-17-fire-extinguisher-bottle-squib/history","analysis":"/api/acts/ad-amd-20-17-fire-extinguisher-bottle-squib/analysis","conflicts":"/api/acts/ad-amd-20-17-fire-extinguisher-bottle-squib/conflicts","importantCases":"/api/acts/ad-amd-20-17-fire-extinguisher-bottle-squib/important-cases","documents":"/api/acts/ad-amd-20-17-fire-extinguisher-bottle-squib/documents"}}
