If not fixed, these cracks could leak fuel and cause an **engine fire**, leading to significant damage and safety risks.\n\n**How to comply**\nOperators must carry out the replacement work following the exact technical instructions in a United States Federal Aviation Administration (FAA) directive (AD 90-26-01). The Australian directive essentially adopts the US safety standard to ensure consistency with international aviation safety requirements."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cf6-16-fuel-manifold-support-bracket","history":"/api/acts/ad-cf6-16-fuel-manifold-support-bracket/history","analysis":"/api/acts/ad-cf6-16-fuel-manifold-support-bracket/analysis","conflicts":"/api/acts/ad-cf6-16-fuel-manifold-support-bracket/conflicts","importantCases":"/api/acts/ad-cf6-16-fuel-manifold-support-bracket/important-cases","documents":"/api/acts/ad-cf6-16-fuel-manifold-support-bracket/documents"}}
