Federal Aviation Administration January 17, 2014 – Federal Register Recent Federal Regulation Documents

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.

This rule establishes, amends, suspends, or revokes Standard Instrument Approach Procedures (SIAPs) and associated Takeoff Minimums and Obstacle Departure Procedures for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, adding new obstacles, or changing air traffic requirements. These changes are designed to provide safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.
