Federal Aviation Administration 2012 – Federal Register Recent Federal Regulation Documents

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 renew for full clearance an information collection that has been granted emergency clearance. The commercial air tour operational data provided to the FAA and NPS will be used by the agencies as background information useful in the development of air tour management plans and voluntary agreements for purposes of meeting the mandate of the National Parks Air Tour Management Act (NPATMA) of 2000.

The Federal Aviation Administration is requesting public comment on the Dunkirk Airport (DKK), Dunkirk, New York, Notice of Proposed Release from Aeronautical Use of approximately 2.666 +/- acres of airport property, to allow for non-aeronautical development. The 2.666 +/- acres of land are proposed to be transferred to the Town of Sheridan for use as public right-of-way for the relocation of Newell Road. The released lands will be exchanged for the 2.006 acres +/- of the existing Newell Road right-of-way currently owned by the Town of Sheridan. Documents reflecting the Sponsor's request are available, by appointment only, for inspection at the Office of the Chautauqua County Executive and the FAA New York Airport District Office.

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

We propose to adopt a new airworthiness directive (AD) for all The Boeing Company Model 717-200 airplanes. This proposed AD was prompted by multiple reports of cracks of overwing frames. This proposed AD would require repetitive inspections for cracking of the overwing frames, and related investigative and corrective actions if necessary. We are proposing this AD to detect and correct such cracking that could sever a frame, which may increase the loading of adjacent frames, and result in damage to the adjacent structure and consequent loss of structural integrity of the airplane.

We are adopting a new airworthiness directive (AD) for certain Pratt & Whitney Canada PT6A-38, -41, -42, -42A, -61, -64, -66, -66B, - 110, -112, -114, -114A, -121, -135, and -135A series turboprop engines. This AD requires removal from service of certain part manufacturer approval (PMA) replacement Timken Alcor Aerospace Technologies, Inc. (TAATI) first stage sun gears and planet gears installed in the reduction gearbox. This AD was prompted by failures of certain first stage sun gears manufactured by TAATI. We are issuing this AD to prevent failure of the sun gear and planet gears which will result in an engine in-flight shut down, possible uncontained engine failure, aircraft damage, and serious injuries.

We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A320-214 and-232 airplanes. This proposed AD was prompted by reports that medium-head fasteners were installed in lieu of shear-head fasteners on a certain upper panel which manufacturer fatigue and damage tolerance analyses demonstrated could have an affect on panel fatigue life. This proposed AD would require repetitive inspections for cracking of certain fasteners, and repairs if necessary. We are proposing this AD to detect and correct cracking which could result in the loss of structural integrity of the airplane.

In accordance with the National Environmental Policy Act of 1969, as amended (NEPA; 42 U.S.C. 4321 et seq.), Council on Environmental Quality NEPA implementing regulations (40 Code of Federal Regulations parts 1500 to 1508), and FAA Order 1050.1E, Change 1, the FAA is announcing the availability of the Final EA and FONSI for the Launch and Reentry of SpaceShipTwo Reusable Suborbital Rockets at the Mojave Air and Space Port. The Final EA was prepared to analyze the potential environmental impacts of issuing experimental permits and/or launch licenses to operate SpaceShipTwo reusable suborbital rockets and WhiteKnightTwo carrier aircraft at the Mojave Air and Space Port in Mojave, California. Under the Proposed Action, the FAA would issue experimental permits and/or launch licenses to multiple operators for the operation of SpaceShipTwo and WhiteKnightTwo at the Mojave Air and Space Port. Both WhiteKnightTwo and SpaceShipTwo would be piloted during operations. The Mojave Air and Space Port comprises an area of approximately 3,000 acres in Kern County, California, and is east of the unincorporated town of Mojave. The Final EA addresses the potential environmental impacts of implementing the Proposed Action and the No Action Alternative of not issuing an experimental permit and/or launch license for the operation of SpaceShipTwo and WhiteKnightTwo at the Mojave Air and Space Port. The FAA has posted the Final EA and FONSI on the FAA/AST Web site: https://www.faa.gov/about/officeorg/headquartersoffices/ast/ environmental/review/permits/. A paper copy of the Final EA and FONSI may be reviewed during regular business hours at the following locations: Edwards AFB Base Library, 95 SPTG/SVMG, 5 West Yeager Blvd., Building 2665, Edwards AFB, CA 93524-1295. Kern County Library, Boron Branch, 26967 20 Mule Team Road, Boron, CA 93516. Kern County Library, California City Branch, 9507 California City Boulevard, California City, CA 93505. Kern County Library, Kernville Branch, 48 Tobias Street, Kernville, CA 93238. Kern County Library, Mojave Branch, 16916-1/2 Highway 14, Mojave, CA 93501. Kern County Library, Ridgecrest Branch, 131 East Las Flores Avenue, Ridgecrest, CA 93555. Kern County Library, Tehachapi Branch, 450 West F Street, Tehachapi, CA 93561.

Kern River Valley Library, Wanda Kirk Branch (Rosamond), 3611 Rosamond Boulevard, Rosamond, CA 93560. Additional Information: Under the Proposed Action, the FAA would issue experimental permits and/or launch licenses for the operation of SpaceShipTwo and WhiteKnightTwo at the Mojave Air and Space Port in Mojave, CA. The Proposed Action does not include any construction activities. The Mojave Air and Space Port's existing infrastructure would be used for takeoff and landing activities. Experimental permits would be valid for one year. Launch licenses would be valid for two years. The FAA could renew experimental permits and launch licenses if requested, in writing, by the permitees at least 60 days before the permit expires, and/or by the licensees at least 90 days before the license expires. The Final EA assumes that the FAA could issue either new or renewed experimental permits and/or launch licenses. For purposes of analyzing environmental impacts in the Final EA, the FAA developed a conservative set of assumptions regarding the possible number of launches and reentries that could be conducted under any one experimental permit and/or launch license for the SpaceShipTwo at the Mojave Air and Space Port. The FAA has assumed a maximum of up to 30 total launches and reentries per year of SpaceShipTwo for a total of up to 150 launches and reentries of SpaceShipTwo between 2012 and 2016. This estimation is a conservative number and considers potential multiple launches per day and potential launch aborts. The only alternative to the Proposed Action analyzed in the Final EA is the No Action Alternative. Under the No Action Alternative, the FAA would not issue experimental permits and/or launch licenses for the operation of SpaceShipTwo and WhiteKnightTwo from the Mojave Air and Space Port. Existing operations at Mojave Air and Space Port would continue. The resource areas considered in the Final EA include air quality; biological resources (including fish, wildlife, and plants); historical, architectural, archaeological, and cultural resources; hazardous materials, pollution prevention, and solid waste; health and safety; land use (including Department of Transportation Section 4(f) properties); light emissions and visual resources; noise and compatible land use; socioeconomic resources, environmental justice, and children's environmental health and safety; and cumulative impacts.

We are adopting a new airworthiness directive (AD) for certain 2-Fokker Services B.V.2-Model F.28 Mark 0100 airplanes. This AD was prompted by reports of failure of the main fitting on Messier-Dowty main landing gear (MLG) units due to fatigue cracking in the area of the filler and bleeder holes, and failure of the sliding member due to fatigue cracking at the area of the chrome run-out/lower radius of the sliding tube portion of the sliding member. This AD requires modification and re-identification of the MLG units, or replacement of the MLG unit with a modified one. We are issuing this AD to detect and correct fatigue cracking of the main fitting or sliding member on the MLG, which could lead to failure of the MLG and possibly loss of control of the airplane during landing rollout.

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.

We are superseding an existing airworthiness directive (AD) that applies to The Boeing Company Model 767-200, -300, and -300F series airplanes. That AD currently requires inspections to detect cracking or corrosion of the fail-safe straps between the side fitting of the rear spar bulkhead at body station 955 and the skin; and follow- on and corrective actions. This new AD expands the applicability; and adds an inspection for cracking in the fail-safe strap, and repair or replacement if necessary. This AD was prompted by additional reports of cracks in 51 fail-safe straps on 41 airplanes; we have also received a report of a crack found in the ``T'' fitting that connects the fail- safe strap to the outboard edge of the pressure deck. We are issuing this AD to detect and correct fatigue cracking or corrosion of the fail-safe straps and the ``T'' fittings, which could result in cracking of adjacent structure and consequent reduced structural integrity of the fuselage.

We propose to supersede an existing airworthiness directive (AD) that applies to all Rolls-Royce plc (RR) RB211-Trent 875-17, RB211-Trent 877-17, RB211-Trent 884-17, RB211-Trent 884B-17, RB211- Trent 892-17, RB211-Trent 892B-17, and RB211-Trent 895-17 turbofan engines. The existing AD currently requires initial and repetitive ultrasonic inspections (UIs) of certain low-pressure (LP) compressor blades identified by serial number (S/N). This proposed AD would require the same actions but expands the population of blades. We are proposing this AD to prevent LP compressor blades from failing due to blade root cracks, which could lead to uncontained engine failure and damage to the airplane.

We are adopting a new airworthiness directive (AD) for all Airbus Model A300 B2-1C, B2K-3C, B2-203, B4-2C, B4-103, and B4-203 airplanes. This AD was prompted by analysis that in a specific failure case of the upper primary attachment of the trimmable horizontal stabilizer actuator (THSA), the THSA upper secondary attachment engaged because it could only withstand the loads for a limited period of time. This AD requires installing three secondary retention plates for the gimbal bearings on the THSA upper primary attachment. We are issuing this AD to prevent failure of the secondary load path, which could result in loss of control of the airplane.

This action amends VOR Federal airway V-14 in the vicinity of St. Louis, MO. The FAA is taking this action to correct the V-14 description contained in Part 71 to ensure it matches the information contained in the FAA's aeronautical database, matches the depiction on the associated charts, and to ensure the safety and efficiency of the National Airspace System (NAS).

The Federal Aviation Administration (FAA) and the National Park Service (NPS), in accordance with the National Parks Air Tour Management Act of 2000, announce the next meeting of the National Parks Overflights Advisory Group (NPOAG) Aviation Rulemaking Committee (ARC). This notification provides the date, location, and agenda for the meeting.

The FAA is issuing this notice to advise the public of the thirteenth meeting of RTCA Special Committee 224, Airport Security Access Control Systems

The FAA proposes to rule and invite public comment on the release of land at the South Texas Regional Airport at Hondo under the provisions of Section 125 of the Wendell H. Ford Aviation Investment Reform Act for the 21st Century (AIR 21).

We are adopting a new airworthiness directive (AD) for all Airbus Model A310 series airplanes. This AD was prompted by a report of an electrical arc and hydraulic haze in the wheel bay of the left-hand main landing gear (MLG) possibly resulting from chafing between the hydraulic high pressure hose and electrical wiring of the green electrical motor pump (EMP). This AD requires temporarily prohibiting in-flight use of the green EMPs; temporarily revising the airplane flight manual (AFM) limitations section; temporarily installing a placard in the cockpit overhead panel; doing a one-time general visual inspection for correct condition and installation of hydraulic pressure hoses, electrical conduits, feeder cables, and associated clamping devices; and corrective action if necessary. We are issuing this AD to detect and correct chafing of hydraulic pressure hoses and electrical wiring of the green EMPs, which in combination with a system failure, could cause an uncontrolled and undetected fire in the MLG bay.

This notice announces a public meeting of the FAA's Aviation Rulemaking Advisory Committee (ARAC) to discuss transport airplane and engine (TAE) issues.

We are adopting a new airworthiness directive (AD) for all Turbomeca S.A. Arriel 2B and 2B1 turboshaft engines. This AD was prompted by the discovery of non-conformities of certain power turbine (PT) blade fir-tree roots. This AD requires removing the affected PT blades from service on or before reaching a new reduced life limit for those certain PT blades. We are issuing this AD to prevent PT blade rupture, which could result in an uncommanded in-flight engine shutdown, forced autorotation landing, or accident.

We are superseding an existing airworthiness directive (AD) for certain Sicma Aero Seat Model 9401, 9402, 9404, 9505, 9406, 9407, 9408, and 9409 series passenger seat assemblies, installed on, but not limited to, ATRGIE Avions de Transport R[eacute]gional Model ATR42 and ATR72 airplanes. That AD currently requires repetitive detailed inspections for cracking of the central and lateral spreaders of the affected seats, and repair or replacement of the spreader if necessary. This AD was prompted by a determination that the existing AD included Model 9505 series passenger seat assemblies in the applicability instead of Model 9405 series passenger seat assemblies. We are issuing this AD to detect and correct cracking of the central and lateral spreaders, which could lead to further cracking of the seat spreaders, causing injury to passengers or crew members during heavy turbulence in flight or in the event of an emergency landing.

This notice concerns two petitions for waiver submitted to the FAA by Space Exploration Technologies Corp. (SpaceX): a petition to waive the restriction that the risk to the public from the launch of an expendable launch vehicle not exceed an expected average number of 0.00003 casualties (Ec

We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-2B16 (CL-604 Variant) airplanes. This AD was prompted by multiple reports of short circuit events during pre- delivery inspections and test flights, one of which resulted in smoke in the cockpit. This AD requires replacing or relocating of certain circuit breaker panel (CBP) bus bars on certain airplanes, inspecting for any loose or improperly crimped lugs in certain electrical panel locations and replacement if necessary, and inspection for foreign object damage in certain areas and removal if necessary. We are issuing this AD to prevent arcing, damage to adjacent structure, smoke in the cockpit, or loss of system redundancies.

We are superseding an existing airworthiness directive (AD) for all EMBRAER Model ERJ 170 airplanes. That AD currently requires revising the Airworthiness Limitations Section (ALS) of the Instructions for Continued Airworthiness (ICA) to incorporate new structural inspection requirements. Since we issued that AD, during full scale fatigue testing, cracks were found in certain structural components of the airplane. Analysis of these cracks resulted in the manufacturer modifying the ALS of EMBRAER 170 Maintenance Review Board Report (MRBR), to include new inspections tasks, or modifying the current tasks and their respective thresholds and intervals. This new AD requires revising the maintenance program to incorporate new or revised structural inspection requirements. We are issuing this AD to detect and correct fatigue cracking which could result in the loss of structural integrity of the airplane.

We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model DHC-8-400 series airplanes. This AD was prompted by test reports that showed that failure of a retract port flexible hose of a main landing gear (MLG) retraction actuator could cause excessive hydraulic fluid leakage. This AD requires a detailed inspection for defects and damage of the retract port flexible hose on the left and right MLG retraction actuator and replacement of the flexible hose if needed. We are issuing this AD to detect and correct defects and damage of the retract port flexible hose which could lead to an undamped extension of the MLG and could result in MLG structural failure, leading to an unsafe asymmetric landing configuration.

We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-2B16 (CL-604 Variant) airplanes. This AD was prompted by reports of the air driven generator (ADG) failing to power essential buses during functional tests, due to the low threshold setting of the circuit protection on the ADG's generator control unit (GCU) preventing the ADG from supplying power to the essential buses. This AD requires installing a new or serviceable ADG GCU. We are issuing this AD to prevent loss of power from the ADG to the essential buses which, in the event of an emergency, could prevent continued safe flight.
