Proposed Advisory Circular 120-YY, Widespread Fatigue Damage on Metallic Structure
This notice announces the availability of and requests comments on a proposed advisory circular (AC) which provides guidance to design approval holders for certain transport category airplanes and on repairs and alterations to those airplanes for developing means to preclude widespread fatigue. This proposed AC complements revisions to the airworthiness standards that are being proposed by a separate notice. This notice is necessary to give all interested persons an opportunity to present their views on the proposed AC.
Airworthiness Directives; Boeing Model 767 Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for all Boeing Model 767 airplanes. This proposed AD would require repetitive detailed and high frequency eddy current (HFEC) inspections of the station (STA) 1809.5 bulkhead for cracking and corrective actions if necessary. This proposed AD results from fatigue cracks found in the forward outer chord and horizontal inner chord at STA 1809.5. We are proposing this AD to detect and correct cracking in the bulkhead structure at STA 1809.5, which could result in failure of the bulkhead structure for carrying the flight loads of the horizontal stabilizer, and consequent loss of controllability of the airplane.
Supplemental Notice of Availability of the Final Environmental Impact Statement Containing a DOT Section 4(f)/303(c) Evaluation for a Proposed Replacement Airport for the City of St. George, UT
The Federal Aviation Administration (FAA) is issuing a supplemental Supplement Notice of Availability of the Final Environmental Impact Statement containing a DOT Section 4(f)(/303(c) evaluation for a Proposed Replacement Airport for the City of St. George, Utah, published on May 12, 2006 (Volume 71 FR 277770). This supplemental notice is to advise the public that additional copies of the Final Environmental Impact Statement (FEIS) for the proposed replacement airport for the City of St. George, Utah, have been made available for public review at six additional locations. Other than the addition of the six locations for public review, all other information in the original notice remains the same, including the public review period, which begins May 19, 2006. The FAA will accept comments on new and/or revised/updated information and analyses disclosed in Appendices T through Y and in Chapter 6, section 6.4, Air Quality, until 5 p.m. Pacific Daylight Time, Monday, July 3, 2006, at the address listed in the section entitled FOR FURTHER INFORMATION CONTACT.
Public Notice for Waiver of Aeronautical Land-Use Assurance; Mount Comfort Airport; Indianapolis, IN
The Federal Aviation Administration (FAA) is considering a proposal to change a portion of the airport from aeronautical use to non-aeronautical use and to authorize the sale of the airport property. The 3.27-acre parcel is on Airport Boulevard near the western border of the airport. It is contained within Parcels 18-1 and 18-2 on the current Exhibit A. The current Airport Layout Plan identifies this land as part of an area reserved for future aviation related development. The land was acquired under FAA Project No(s). ADAP 5-18-0037-01 and ADAP 5-18-0037-02. The release of the land is considered beneficial to the safety of the airport because the Buck Creek Township Fire Department proposes to construct a new fire station at this location. Approval does not constitute a commitment by the FAA to financially assist in the disposal of the subject airport property nor a determination of eligibility for grant-in-aid funding from the FAA. The disposition of proceeds from the disposal of the airport property will be in accordance FAA's Policy and Procedures Concerning the Use of Airport Revenue, published in the Federal Register on February 16, 1999. In accordance with section 47107(h) of title 49, United States Code, this notice is required to be published in the Federal Register 30 days before modifying the land-use assurance that requires the property to be used for an aeronautical purpose.
Modification and Revocation of Restricted Areas R-3007A, B, C, D, and E; Townsend, GA
This action reconfigures Restricted Areas R-3007A, B, C, and D, and revokes Restricted Area R-3007E, Townsend, GA, by reducing the lateral size, increasing the vertical limits, and by increasing the time of designation of the restricted airspace by six hours per day. The FAA is taking this action to better accommodate Department of Defense (DOD) training requirements and to eliminate restricted airspace that is no longer needed by the military. Additionally, the name of the using agency for all R-3007 subareas is changed to reflect the current organizational title. This action also makes a minor correction to the latitude/longitude positions of two points in the descriptions of R-3007B and R-3007C.
Noise Compatibility Program Notice; Collin County Regional Airport; McKinney, Texas
The Federal Aviation Administration (FAA) announces its findings on the noise compatibility program submitted by the city of McKinney 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 nonfederal responsibilities in Senate Report No. 96-52 (1980). On November 1, 2005 the FAA determined that the noise exposure maps submitted by the city of McKinney under Part 150 were in compliance with applicable requirements. On April 28, 2006, the FAA approved the Collin County Regional Airport noise compatibility program. Most of the recommendations of the program were approved.
