Federal Aviation Administration August 2011 – Federal Register Recent Federal Regulation Documents

We are adopting a new 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 MCAI describes the unsafe condition as:

This action proposes to establish Class D and E airspace at Frederick, MD, to accommodate new Area Navigation (RNAV) Global Positioning System (GPS) Standard Instrument Approach Procedures (SIAPs) at Frederick Municipal Airport. This action would enhance the safety and management of Instrument Flight Rules (IFR) operations for SIAPs at the airport.

We are adopting a new 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 MCAI describes the unsafe condition as:

This notice announces the issuance of Advisory Circular (AC) 20-24C, Approval of Propulsion Fuels and Lubricating Oils. This AC provides guidance on regulations and policy applicable to adding fuels and oils to type certificates as engine, aircraft, or auxiliary power unit (APU) operating limitations. It also provides acceptable methods, but not the only methods, that may be used to approve aircraft, engines, or APUs to operate with specified propulsion fuels and lubricating oils.

This action proposes to amend Class D and Class E airspace at Northeast Philadelphia Airport, North Philadelphia, PA, due to the closing of Willow Grove Naval Air Station and Warminster NAWC. This action would enhance the safety and airspace management of Instrument Flight Rules (IFR) operations in the North Philadelphia, PA airspace area.

This action proposes to establish Class E Airspace at Palmyra, PA, to accommodate new Area Navigation (RNAV) Global Positioning System (GPS) Standard Instrument Approach Procedures at Reigle Field. This action would enhance the safety and airspace management of Instrument Flight Rules (IFR) operations at the airport.

This action proposes to establish Class E airspace at Tatitlek, AK. The creation of a standard instrument approach procedure at the Tatitlek Airport has made this action necessary to enhance safety and management of Instrument Flight Rules (IFR) operations.

We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD would require inspecting certain serial number (S/N) first stage turbine disks, part number (P/ N) 3101520-1 and P/N 3107079-1. This proposed AD was prompted by a report of an uncontained failure of a first stage turbine disk that had a metallurgical defect. We are proposing this AD to prevent uncontained failure of the first stage turbine disk and damage to the airplane.

We propose to adopt a new airworthiness directive (AD) for Diamond Aircraft Industries Model H-36 ``DIMONA'' powered sailplanes. 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:

We propose to supersede an existing airworthiness directive (AD) that applies to Model L-1011-385-1, L-1011-385-1-14, and L-1011- 385-1-15 airplanes. The existing AD currently requires implementation of a Supplemental Inspection Document (SID) program of structural inspections to detect fatigue cracking, and repair, if necessary, to ensure continued airworthiness of these airplanes as they approach the manufacturer's original fatigue design life goal. Since we issued that AD, an evaluation by the manufacturer of usage and flight data provided additional information about certain Structurally Significant Details (SSDs) where fatigue damage is likely to occur. This proposed AD would add airplanes to the applicability, change certain inspection thresholds, add three new SSDs, and remove an SSD that has been addressed by a different AD. We are proposing this AD to prevent fatigue cracking that could compromise the structural integrity of these airplanes.

This 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.

We propose to supersede an existing airworthiness directive (AD) that applies to certain Model 737-100 and -200 series airplanes. The existing AD currently requires various inspections for cracks in the outboard chord of the frame at body station (BS) 727 and in the outboard chord of stringer (S) 18A, and repair or replacement of cracked parts. Since we issued that AD, there have been several reports of fatigue cracking in the frame outboard chord at BS 727 and in the radius of the auxiliary chord on airplanes that were not affected by the existing AD. This proposed AD would add airplanes to the applicability statement in the existing AD and add inspections for cracks in the BS 727 frame outboard chords and the radius of the auxiliary chord, for certain airplanes. This proposed AD would also remove the inspections of the outboard chord of S-18A required by the existing AD. We are proposing this AD to detect and correct fatigue cracking of the outboard and auxiliary chords, which could result in reduced structural integrity of the outboard chord and consequent rapid decompression of the airplane.

We are adopting a new airworthiness directive (AD) for the products listed above that would supersede an existing AD. 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:

This action will modify Class E airspace at Forsyth, MT. Controlled airspace is necessary to accommodate aircraft using Area Navigation (RNAV) Global Positioning System (GPS) standard instrument approach procedures at Tillitt Field Airport. This action also corrects a typographical error in the regulatory text for the Class E airspace area. This action improves the safety and management of Instrument Flight Rules (IFR) operations at the airport.

In accordance with the Paperwork Reduction Act of 1995, FAA invites public comments about our intention to request the Office of Management and Budget (OMB) approval to reinstate a previously discontinued information collection. The Survey of Airman Satisfaction with Aeromedical Certification Services assesses airman opinion of key dimensions of service quality.

This action clarifies the term ``actively engaged'' for the purposes of application for and renewal of an inspection authorization. It also responds to the comments submitted to the proposed policy and revises portions of that proposal. This action amends the Flight Standards Management System FAA Order 8900.1.

This action modifies Class D and Class E airspace at Lawson Army Airfield (AAF), Columbus, GA, by removing the reference to the Columbus Metropolitan Airport Class C airspace area from the description. Controlled airspace at Columbus Metropolitan Airport is being downgraded due to decreased air traffic volume. This action is necessary for the safety and management of air traffic within the National Airspace System. This action also updates the geographic coordinates of Columbus Lawson AAF.

In preparation for the twenty-third meeting of the International Civil Aviation Organization's (ICAO) Dangerous Goods Panel (DGP) to be held October 11-21, 2011, in Montreal, Quebec, Canada, the FAA's Office of Hazardous Materials Safety and the Pipeline and Hazardous Materials Safety Administration's (PHMSA) Office of Hazardous Materials Safety announce a public meeting on September 23, 2011.

This action proposes to modify Class E airspace at Blythe, CA. Controlled airspace is necessary to accommodate aircraft using Area Navigation (RNAV) Global Positioning System (GPS) standard instrument approach procedures at Blythe Airport. The FAA is proposing this action to enhance the safety and management of aircraft operations at the airport.

We are adopting a new airworthiness directive (AD) for the products listed above. This AD requires inspecting the wings for internal and external damage, repairing any damage, reinforcing the wings, installing operational limitation placards in the cockpit, and adding limitations to the airplane flight manual supplement. This AD was prompted by a review of installed Flint Aero, Inc. wing tip auxiliary fuel tanks, Supplemental Type Certificate (STC) SA5090NM. We are issuing this AD to detect and correct damage in the wings and to prevent overload failure of the wing due to the installation of the STC. Damage in the wing or overload failure of the wing could result in structural failure of the wing, which could result in loss of control.
