## Summary

We propose to supersede airworthiness directives (ADs) 90-26- 01, 91-20-02, and 2009-05-02, which apply to all General Electric Company (GE) CF6-80C2 and CF6-80E1 series turbofan engines. Since we issued ADs 90-26-01, 91-20-02, and 2009-05-02, we received a report of an undercowl fire caused by a manifold high-pressure fuel leak, and several additional reports of fuel leaks. This proposed AD would require additional repetitive inspections, replacement of tube (block) clamp, and inspection of fuel manifolds for wear at each tube (block) clamp location. We are proposing this AD to prevent failure of the fuel manifold, which could lead to uncontrolled engine fire, engine damage, and damage to the airplane.
