These documents contain the technical procedures for addressing the safety issue.\n\n**When it must be done:**\nWithin 100 hours of flight time after 29 August 1969.\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 directive addresses potential electrical system problems with the auxiliary fuel pump that could affect fuel delivery and flight safety."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-205-6-amdt-2-auxiliary-fuel-pump-electrical-system","history":"/api/acts/ad-cessna-205-6-amdt-2-auxiliary-fuel-pump-electrical-system/history","analysis":"/api/acts/ad-cessna-205-6-amdt-2-auxiliary-fuel-pump-electrical-system/analysis","conflicts":"/api/acts/ad-cessna-205-6-amdt-2-auxiliary-fuel-pump-electrical-system/conflicts","importantCases":"/api/acts/ad-cessna-205-6-amdt-2-auxiliary-fuel-pump-electrical-system/important-cases","documents":"/api/acts/ad-cessna-205-6-amdt-2-auxiliary-fuel-pump-electrical-system/documents"}}
