Federal Aviation Administration July 16, 2008 – Federal Register Recent Federal Regulation Documents

This action will establish Class E airspace at Fort Collins- Loveland Municipal Airport, Fort Collins, CO. Controlled airspace is necessary to accommodate Instrument flight rules (IFR) operations from this airport located in mountainous terrain and enable positive control at Fort Collins-Loveland Municipal Airport, Fort Collins, CO. This will enhance the safety and management of aircraft operations at Fort Collins-Loveland Municipal Airport, Fort Collins, CO.

This notice announces amendments to the technical specification in the Interagency Air Cartographic Committee Specifications that address the depiction of man-made obstructions 500 feet or more above ground level (AGL) on the World Aeronautical Chart series.

This action establishes four Federal airways in the National Airspace System (NAS) to replace four non-part 95 routes in Alaska. The routes consist of three Very High Frequency Omnidirectional Range (VOR) Federal airways, and one Low/Medium Frequency (L/MF) Colored Federal airway in Alaska. The conversion of these non-part 95 routes would change uncharted nonregulatory airways requiring special aircrew authorization to Federal Airways, thus adding to the instrument flight rules (IFR) airway and route infrastructure in Alaska. The addition of these routes improves the management of air traffic operations and thereby enhances safety. A minor change to the description of V-619 also is being made.

The FAA is adopting a new airworthiness directive (AD) for IAE V2500-A1, V2522-A5, V2524-A5, V2527-A5, V2527E-A5, V2527M-A5, V2530-A5, V2533-A5, V2525-D5, and V2528-D5 turbofan engines. This AD requires removing certain No. 4 bearing oil system components from service at the next shop visit or by an end date determined by the engine model. This AD results from instances of oil loss from the No. 4 bearing compartment. We are issuing this AD to prevent heat damage to high- pressure turbine (HPT) and low-pressure turbine (LPT) critical life limited hardware such as the HPT stage 1-2 airseal. Damage to the HPT stage 1-2 airseal could cause uncontained engine failure and damage to the airplane.
