Airworthiness Directives; General Electric Company CF6-80C2 and CF6-80E1 Series Turbofan Engines
This action withdraws a notice of proposed rulemaking (NPRM) that proposed a new airworthiness directive (AD), applicable to General Electric Company (GE) CF6-80C2 and CF6-80E1 series turbofan engines. That action would have required replacement of all clevis pins installed on the thrust reverser central drive units and upper and lower actuators, or replacement of pins that fail an on-wing rebound hardness test. Since we issued that NPRM, we determined there is no unsafe condition that warrants issuing an AD. The likelihood of this event occurring again and significantly damaging an aircraft is very low. Accordingly, we withdraw the proposed rule.
Modification of Class D Airspace; MacDill AFB, FL
This action modifies Class D Airspace at MacDill AFB, FL. The MacDill AFB Air Traffic Control Tower no longer operates on a full time basis; therefore, the Class D Airspace associated with the tower operations must be modified to reflect the times when the controlled airspace is effective. This action enhances the National Airspace System by relaxing the restrictions to the controlled airspace areas in the vicinity of MacDill AFB, FL.
Standard Instrument Approach Procedures, and Takeoff Minimums and Obstacle Departure Procedures; Miscellaneous Amendments
This 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.
