Federal Aviation Administration May 23, 2012 – Federal Register Recent Federal Regulation Documents

This action amends the description of restricted area R-2101, Anniston Army Depot, AL, by removing the abbreviation ``CST'' from the time of designation, and by including a controlling agency for the restricted area. This amendment does not change the dimensions of, or activities conducted within, R-2101.

The FAA is issuing this notice to advise the public of the thirtieth meeting of RTCA Special Committee 206, Aeronautical Information and Meteorological Data Link Services.

This action proposes to establish Class E Airspace at Apopka, FL, to accommodate the Area Navigation (RNAV) Global Positioning System (GPS) Standard Instrument Approach Procedures at Orlando Apopka Airport. This action would enhance the safety and airspace management of Instrument Flight Rules (IFR) operations at the airport.

We are superseding an existing airworthiness directive (AD) for all International Aero Engines AG (IAE) V2500-A1, V2525-D5 and V2528-D5 turbofan engines, and certain serial numbers (S/Ns) of IAE V2522-A5, V2524-A5, V2527-A5, V2527E-A5, V2527M-A5, V2530-A5, and V2533-A5 turbofan engines. That AD currently requires initial and repetitive ultrasonic inspections (USIs) of certain high-pressure compressor (HPC) stage 3 to 8 drums, and replacement of drum attachment nuts. This new AD expands the affected population for initial and repetitive inspections of the HPC stage 3 to 8 drum, introduces an eddy current inspection (ECI) procedure, and requires additional cleaning and repetitive USI of some HPC stage 3 to 8 drums. We are issuing this AD to prevent uncontained failure of the HPC stage 3 to 8 drum, which could result in damage to the airplane.
