The tank inspections address potential defects in baffled fuel cells that could affect fuel flow or cause leaks — both serious flight safety hazards.\n\n**What must be done:**\n- Follow specific Beechcraft Service Instructions (SI 0492-281 or 0484-281, depending on the aircraft)\n- Inspect fuel tanks if they have baffled cells and haven't been inspected under the earlier AD/BEECH 55/17\n- Complete everything within **100 hours of flight time** after 31 July 1973\n\n**Key point:** This is a **time-limited compliance requirement** — once the 100 hours have passed since July 1973, this directive is effectively historical for any aircraft still in service (though records would need to show compliance)."}},"importantCases":[],"_links":{"self":"/api/acts/ad-beech-55-32-fuel-system-placards","history":"/api/acts/ad-beech-55-32-fuel-system-placards/history","analysis":"/api/acts/ad-beech-55-32-fuel-system-placards/analysis","conflicts":"/api/acts/ad-beech-55-32-fuel-system-placards/conflicts","importantCases":"/api/acts/ad-beech-55-32-fuel-system-placards/important-cases","documents":"/api/acts/ad-beech-55-32-fuel-system-placards/documents"}}
