This directive prevents accidents by forcing operators to check for and fix these defects.\n\n**What must be done:**\n- **Inspect:** Examine fuel manifolds for weld joint failures\n- **Replace:** Install new manifolds where defects are found\n- **Follow technical specs:** Use the specific procedures set out in US Federal Aviation Administration Directive 91-20-02 and General Electric Service Bulletins 73-115 and 73-114\n- **Comply by:** 17 September 1992"}},"importantCases":[],"_links":{"self":"/api/acts/ad-cf6-22-fuel-manifold-inspection-and-replacement","history":"/api/acts/ad-cf6-22-fuel-manifold-inspection-and-replacement/history","analysis":"/api/acts/ad-cf6-22-fuel-manifold-inspection-and-replacement/analysis","conflicts":"/api/acts/ad-cf6-22-fuel-manifold-inspection-and-replacement/conflicts","importantCases":"/api/acts/ad-cf6-22-fuel-manifold-inspection-and-replacement/important-cases","documents":"/api/acts/ad-cf6-22-fuel-manifold-inspection-and-replacement/documents"}}
