Department of Transportation June 8, 2015 – Federal Register Recent Federal Regulation Documents

The FAA is issuing this notice to advise the public of the thirty-third meeting of the RTCA Special Committee 224, Airport Security Access Control Systems.

The Board is publishing, and providing the public an opportunity to comment on, the 2014 weighted average state tax rates for each Class I railroad, as calculated by the Association of American Railroads (AAR), for use in the Revenue Shortfall Allocation Method (RSAM).

This notice contains a summary of a petition seeking relief from specified requirements of Title 14 of the Code of Federal Regulations. The purpose of this notice is to improve the public's awareness of, and participation in, the FAA's exemption process. Neither publication of this notice nor the inclusion or omission of information in the summary is intended to affect the legal status of the petition or its final disposition.

This rule establishes, amends, suspends, or removes Standard Instrument Approach Procedures (SIAPs) and associated Takeoff Minimums and Obstacle Departure Procedures (ODPs) 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.

We propose to adopt a new airworthiness directive (AD) for all Pratt & Whitney (PW) PW4164, PW4168, PW4168A, PW4164-1D, PW4168-1D, PW4168A-1D, and PW4170 turbofan engines. This proposed AD was prompted by crack finds in the 6th stage low-pressure turbine (LPT) disk. This proposed AD would require removal of affected 6th stage LPT disks. We are proposing this AD to prevent failure of the 6th stage LPT disk, which could lead to an uncontained disk release, damage to the engine, and damage to the airplane.
