Federal Aviation Administration May 2010 – Federal Register Recent Federal Regulation Documents

This action proposes to revise Class E airspace at Kulik Lake, AK. This action would correct an error in the legal description of the Kulik Lake airspace description, which makes this action necessary to enhance safety and management of Instrument Flight Rules (IFR) operations.

The Secretary and the FAA are granting, subject to conditions, the joint waiver request of Delta Air Lines and US Airways from the prohibition on purchasing operating authorizations (``slots'' or ``slot interests'') at LaGuardia Airport (LGA). The grant permits the carriers to consummate a transaction in which Delta would transfer 42 pairs of slot interests to US Airways at Ronald Reagan Washington National Airport (DCA), international route authorities to S[atilde]o Paulo and Tokyo; and terminal space at the Marine Air Terminal at LGA. US Airways would transfer 125 pairs of slot interests to Delta at LGA, and would lease an additional 15 pairs of LGA slot interests with a purchase option, together with terminal space in LGA's Terminal C. The grant is subject to the conditions that the carriers dispose of 14 pairs of slot interests at DCA and 20 pairs of slot interests at LGA to eligible new entrant and limited incumbent carriers, pursuant to procedures set out in this Notice, and achieve a mutually satisfactory agreement regarding gates and associated facilities with any such purchaser.

We propose to adopt a new airworthiness directive (AD) for the products listed above that would supersede an existing AD. 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 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 adopt a new airworthiness directive (AD) for certain Model 737-200, -300, -400, and -500 series airplanes. This proposed AD would require repetitive inspections for cracking of certain fuselage frames and stub beams, and corrective actions if necessary. This proposed AD also provides for an optional repair, which would terminate the repetitive inspections. For airplanes on which a certain repair is done, this proposed AD would also require repetitive inspections for cracking of certain fuselage frames and stub beams, and corrective actions if necessary. This proposed AD results from reports of the detection of fatigue cracks at certain frame sections, in addition to stub beam cracking, caused by high flight cycle stresses from both pressurization and maneuver loads. We are proposing this AD to detect and correct fatigue cracking of certain fuselage frames and stub beams and possible severed frames, which could result in reduced structural integrity of the frames. This reduced structural integrity can increase loading in the fuselage skin, which will accelerate skin crack growth and could result in rapid decompression of the fuselage.

We propose to supersede an existing airworthiness directive (AD) for Tay 650-15 turbofan engines. That AD currently requires initial and repetitive inspections of the low-pressure (LP) turbine discs stage 2 and stage 3 for corrosion, on certain Tay 650-15 serial number engines. This proposed AD results from mandatory continuing airworthiness information (MCAI) issued 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: Strip results from some of the engines listed in the applicability section of this AD revealed excessively corroded low-pressure turbine disks stage 2 and stage 3. The corrosion is considered to be caused by the environment in which these engines are operated. Following a life assessment based on the strip findings it is concluded that inspections for corrosion attack are required. The action specified by this European Aviation Safety Agency (EASA) AD 2008-0122 was intended to avoid a failure of a low- pressure turbine disk stage 2 or stage 3 due to potential corrosion problems which could result in uncontained engine failure and damage to the airplane. It has been later realized that the same unsafe condition could potentially occur on more serial numbers for the Tay 650-15 engines and on the Tay 651-54 engines. This AD, superseding EASA AD 2008-0122, retaining its requirements, is therefore issued to expand the Applicability in adding further engine serial numbers for the Tay 650-15 engines and in adding the Tay 651-54 engines.

This action modifies Jet Route J-3 by terminating the route at the Spokane, WA, VHF omnidirectional range/tactical air navigation (VORTAC) instead of the Canadian border. This action is necessary for the safety and management of instrument flight rules (IFR) operations within the National Airspace System (NAS).

This action extends the comment period for a NPRM that was published on March 12, 2010. In that document, the FAA proposed to amend the airworthiness standards for fatigue tolerance evaluation (FTE) of transport category metallic rotorcraft structures. This notice responds to a request from the European Aviation Safety Agency (EASA) to extend the comment period to the proposal.

This action proposes to modify the legal description of VHF Omnidirectional Range (VOR) Federal Airways V-82, V-175, V-191, and V- 430 in the vicinity of Bemidji, MN. The Bemidji (BJI) VOR, navigation aid that forms a segment of these airways has been out of service for over two years due to terrain and new construction signal interference problems and is planned for decommissioning. An airway intersection reporting point is being established in the same location as the BJI VOR to restore a navigable route structure to the area similar to what existed prior to the loss of service from the navigation aid.

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 MCAI describes the unsafe condition as:

The FAA is correcting a typographical error in an existing airworthiness directive (AD) that was published in the Federal Register on March 11, 2010. The error resulted in an imprecise compliance time in a table. This AD applies to certain Airbus Model A300 B2-1C, B2-203, B2K-3C, B4-103, B4-203, B4-2C airplanes; Model A310 series airplanes; and Model A300 B4-601, B4-603, B4-605R, B4-620, B4-622, and B4-622R airplanes. This AD requires repetitive inspections to detect cracks of the pylon side panels (upper section) at rib 8; and corrective actions if necessary.

This action proposes to amend Class E airspace at Perryville, MO. Additional controlled airspace is necessary to accommodate new Standard Instrument Approach Procedures (SIAPs) at Perryville Municipal Airport, Perryville, MO. The FAA is taking this action to enhance the safety and management of Instrument Flight Rules (IFR) operations at the airport.

The FAA's Office of Commercial Space Transportation (AST) requests grant proposals pursuant to its newly funded Commercial Space Transportation Grant Program. This program has an initial appropriation of $500,000 to be used for space transportation infrastructure projects. The FAA desires to award the appropriated funds before the end of fiscal year 2010. The FAA will review and evaluate all applications for a grant under 49 U.S.C. chapter 703 (Chapter 703). The FAA may make one or more grant awards based upon its evaluations of the grant proposals. All grants awarded under this program are discretionary awards.

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