Seventh Meeting, Special Committee 214: Standards for Air Traffic Data Communication Services, Working Group 78 (WG-78)
The FAA is issuing this notice to advise the public of a meeting of the RTCA Special Committee 214, Standards for Air Traffic Data Communication Services.
Proposed Establishment of Class E Airspace; Rushville, NE
This action proposes to establish Class E airspace at Rushville, NE. Controlled airspace is necessary to accommodate new Standard Instrument Approach Procedures (SIAPs) at Modisett Airport, Rushville, NE. The FAA is taking this action to enhance the safety and management of Instrument Flight Rules (IFR) aircraft operations at Modisett Airport.
Public Notice for Waiver of Aeronautical Land-Use Assurance; Midway Airport, Chicago, Illinois
The Federal Aviation Administration (FAA) proposes to rule and invite comment on the release of land at Chicago Midway International Airport under the provisions of Section 125 of the Wendell H. Ford Aviation Investment Act for the 21st Century (AIR21).
Approval of Amendment to Noise Compatibility Program Mobile Regional Airport, Mobile, AL
The Federal Aviation Administration (FAA) announces its findings on the Noise Compatibility Program submitted by the Mobile Airport Authority under the provisions of 49 U.S.C. (the Aviation Safety and Noise Abatement Act, hereinafter referred to as ``the Act'') and 14 CFR Part 150. These findings are made in recognition of the description of Federal and non-Federal responsibilities in Senate Report No. 96-52 (1980). On May 1, 2006, the FAA determined that the noise exposure maps submitted by the Mobile Airport Authority under Part 150 were in compliance with applicable requirements. On October 26, 2006, the FAA approved the Mobile Regional Airport noise compatibility program. Most of the recommendations of the program were approved. On August 29, 2008, the Mobile Airport Authority requested approval to revise two of the ten approved proposed action measures.
Petitions for Exemption; Summary of Petitions Received
This notice contains a summary of certain petitions seeking relief from specified requirements of 14 CFR. The purpose of this notice is to improve the public's awareness of, and participation in, this aspect of FAA's regulatory activities. Neither publication of this notice nor the inclusion or omission of information in the summary is intended to affect the legal status of any petition or its final disposition.
Airworthiness Directives; Rolls-Royce plc (RR) RB211-524 Series Turbofan Engines
The FAA proposes to supersede an existing airworthiness directive (AD) for certain RR RB211-524 series turbofan engines. That AD currently requires initial and repetitive borescope inspections of the head section and meterpanel assembly of the combustion liner, and replacement if necessary with serviceable parts. This proposed AD would require those same inspections, and replacement if necessary with serviceable parts. This proposed AD would also add more part number (P/ N) combustion liners to the applicability of this proposed AD. This proposed AD results from an inquiry submitted by an operator, which resulted in RR performing a complete review of the affected front combustion liner part numbers. We are proposing this AD to prevent deterioration of the engine combustion liner, which can result in combustion liner breakup, case burn-through, engine fire, and damage to the airplane.
