Federal Aviation Administration 2011 – Federal Register Recent Federal Regulation Documents

We are revising an earlier NPRM for the products listed above. This action revises the earlier NPRM by expanding the scope. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:

This action amends Class E airspace for Horseshoe Bay, TX. Decommissioning of the Horseshoe Bay Resort non-directional beacon (NDB) at Horseshoe Bay Resort Airport, Horseshoe Bay, TX, has made this action necessary to enhance the safety and management of Instrument Flight Rule (IFR) operations at the airport.

This action amends Class E airspace at Sturgis, KY. The Tradewater Non-Directional Beacon (NDB) has been decommissioned and new Standard Instrument Approach Procedures (SIAPs) have been developed for Sturgis Municipal Airport. This action enhances the safety and airspace management of Instrument Flight Rules (IFR) operations at the airport.

We are adopting a new airworthiness directive (AD) for the products listed above. This AD requires repetitive inspections for cracking of the fuselage skin of the crown skin panel along the chem- milled step at stringers S-4 left and S-4 right, from stations (STA) 297 through 439, and repair if necessary. This AD also includes terminating action for the repetitive inspections of the repaired areas only. This AD was prompted by reports of cracking in the fuselage skin of the crown skin panel. We are issuing this AD to detect and correct fatigue cracking of the fuselage skin of the crown skin panel, which could result in pressure venting and consequent rapid decompression of the airplane.

This action proposes to amend Class E airspace at Mosby, MO. Decommissioning of the Mosby non-directional beacon (NDB) at Midwest National Air Center Airport, Mosby, MO, has made this action necessary for the safety and management of Instrument Flight Rules (IFR) operations at Midwest National Air Center Airport.

We are adopting a new airworthiness directive (AD) for the products listed above. This AD requires repetitive detailed inspections of the aft pressure bulkhead web for cracking, and repair if necessary. For certain airplanes, this AD also provides for an optional preventative modification of the aft pressure bulkhead web, which would terminate certain repetitive detailed inspections. This AD was prompted by reports of cracks in the aft pressure bulkhead web. We are issuing this AD to detect and correct cracking in the aft pressure bulkhead web, which could adversely affect the structural integrity of the airplane, resulting in difficulty maintaining cabin pressurization or rapid decompression of the airplane.

This document publishes in the Federal Register an amendment adopting airworthiness directive (AD) 2010-02-05 that was sent previously by individual notices to the known U.S. owners and operators of affected airplanes identified above. This AD requires modifying the flight deck door. This AD was prompted by a report indicating that certain equipment of the flight deck door is defective. We are issuing this AD to prevent failure of this equipment, which could jeopardize flight safety.

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

This action withdraws a notice of proposed rulemaking (NPRM) that proposed a new airworthiness directive (AD) to supersede an existing AD, applicable to certain Gulfstream Aerospace Corporation Model G-1159 airplanes. The existing AD requires an inspection to detect cracks or corrosion in the wing structure in the area of Fuselage Station (FS) 452 inboard clothespin attachment fitting, and repair if necessary. The proposed AD would have required repetitive inspections to detect corrosion or cracks in the forward and aft wing attach fittings at FS 345 and 452, respectively, and adjacent wing beam and wing plank areas, and repair if necessary; and the application of corrosion protection treatment. Since the issuance of the NPRM, the Federal Aviation Administration (FAA) has received new data that indicate the aircraft maintenance manual has been revised to include additional inspections that address the unsafe condition detailed in the NPRM and that the full fleet is in compliance with the inspection and applicable repair required by the existing AD. Accordingly, the proposed rule is withdrawn.

We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:

The FAA is considering revising its current Advisory Circular on Obstruction Marking and Lighting to include guidance for Meteorological Evaluation Towers (METs). These towers are erected in remote and rural areas, often are less than 200 feet above ground level (AGL), and fall outside of FAA regulations governing tall structures and their impact on navigable airspace. The proposed marking guidance would enhance the conspicuity of the towers and address the safety related concerns of low level agricultural operations. The FAA seeks comment on the proposed guidance.

Pursuant to Section 10(a)(2) of the Federal Advisory Committee Act (Pub. L. 92-463, 5 U.S.C. App. 2), notice is hereby given of a teleconference of the Commercial Space Transportation Advisory Committee (COMSTAC). The teleconference will take place on Thursday, January 20, 2011, starting at 1:30 p.m. Eastern Standard Time. Individuals who plan to participate should contact Susan Lender, DFO, (the Contact Person listed below) by phone or e-mail for the teleconference call in number. The proposed agenda for this teleconference is to review the structure of the COMSTAC Working Groups. The Committee will examine the current Working Groups and discuss whether it should make changes to the current structure. If changes are necessary, what should they be? Interested members of the public may submit relevant written statements for the COMSTAC members to consider under the advisory process. Statements may concern the issues and agenda items mentioned above or additional issues that may be relevant for the U.S. commercial space transportation industry. Interested parties wishing to submit written statements should contact Susan Lender, DFO, (the Contact Person listed below) in writing (mail or e-mail) by January 14, 2011, so that the information can be made available to COMSTAC members for their review and consideration before the January 20, 2011, teleconference.

Individuals who plan to participate and need special assistance should inform the Contact Person listed below in advance of the meeting.

We are superseding an existing airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The earlier MCAI, Brazilian Airworthiness Directive 2007-08-01, effective September 27, 2007, describes the unsafe condition as:

This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:

We are adopting a new airworthiness directive (AD) for the products listed above. This AD requires repetitive high frequency eddy current inspections for cracking on the hinge bearing lugs of the left and right sides of the center section ribs of the horizontal stabilizer, and related investigative and corrective actions if necessary. This AD was prompted by reports of cracks found on either the left or right (or in one case, both) sides of the center section ribs of the horizontal stabilizer. We are issuing this AD to detect and correct cracking in the hinge bearing lugs of the center section of the left and right ribs, which could result in failure of the hinge bearing lugs and consequent inability of the horizontal stabilizer to sustain the required loads.

We are superseding an existing airworthiness directive (AD) that applies to the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:

The FAA has issued a ROD for the Philadelphia International Airport (PHL), Capacity Enhancement Program (CEP), Environmental Impact Statement (EIS). The City of Philadelphia, the airport sponsor, owns and operates PHL and had requested FAA consider ways to accommodate existing and forecasted aviation demands. The purpose of the CEP is to enhance airport capacity in order to accommodate current and future aviation demand in the Philadelphia Metropolitan Area during all weather conditions. This ROD sets forth FAA's final determination and environmental approvals for the federal actions necessary to implement the CEP at the airport.

The FAA is correcting an airworthiness directive (AD) that published in the Federal Register. That AD applies to the products listed above. The agency docket No. and the engine type in the subject heading and paragraph (c) in the Summary section and the Regulatory text are incorrect. This document corrects that error. In all other respects, the original document remains the same.

This notice contains a summary of a petition 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 the petition or its final disposition.

We are revising an earlier proposed airworthiness directive (AD) for the products listed above. That NPRM proposed replacing the power control relays for the fuel boost pumps and override pumps with new relays having a ground fault interrupt (GFI) feature. That NPRM was prompted by results from fuel system reviews conducted by the manufacturer. This action revises that NPRM for all airplanes by proposing to require an electrical bonding resistance measurement for certain GFI relays to verify that certain bonding requirements are met. This action also revises that NPRM by proposing to require, for certain airplanes, an inspection to ensure that certain screws are properly installed, and re-installing longer screws if necessary. We are proposing this supplemental NPRM to prevent damage to the fuel pumps caused by electrical arcing that could introduce an ignition source in the fuel tank, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane. Since these actions impose an additional burden over that proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes.

The FAA amends its regulation concerning the process for requesting a waiver of the mandatory separation age of 56 for Air Traffic Control Specialists in flight service stations, enroute or terminal facilities, and the David J. Hurley Air Traffic Control System Command Center. Under this final rule, Air Traffic Control Specialists will no longer be required to certify they have not been involved in an operational error (OE), operational deviation (OD), or runway incursion in the past 5 years. The rule will streamline the waiver process and bring it into conformance with current FAA OE and OD reporting policy.
