Industries Commander 100 Series and Volair 10 Series aeroplanes.\n\n**The requirement:** Install a placard (warning sign) next to the fuel filter drain point displaying the exact text: **\"DRAIN AT LEAST ONE (1) PINT OF FUEL FROM EACH TANK\"**. The letters must be at least 1/8 inch (about 3 millimetres) high.\n\n**Why it matters:** Ensures pilots drain sufficient fuel to check for water or contamination before takeoff—a critical safety step to prevent engine failure due to contaminated fuel.\n\n**Timing:** Immediate compliance required (the term \"forthwith\" means without delay)."}},"importantCases":[],"_links":{"self":"/api/acts/ad-ac-100-10-fuel-system-placard","history":"/api/acts/ad-ac-100-10-fuel-system-placard/history","analysis":"/api/acts/ad-ac-100-10-fuel-system-placard/analysis","conflicts":"/api/acts/ad-ac-100-10-fuel-system-placard/conflicts","importantCases":"/api/acts/ad-ac-100-10-fuel-system-placard/important-cases","documents":"/api/acts/ad-ac-100-10-fuel-system-placard/documents"}}
