Airworthiness Directives; Raytheon Aircraft Company Model 390 Airplanes
We are adopting a new airworthiness directive (AD) for certain Raytheon Aircraft Company Model 390 airplanes. This AD requires you to inspect the spigot bearing, part number (P/N) MS14104-16, for the proper position in the spigot fitting assembly and to install the wing spigot bearing retainer kit, P/N 390-4304-0001. We are issuing this AD to detect spigot bearings that are not positioned flush with the fitting assembly. This condition could result in the spigot bearing becoming disengaged from the fitting assembly, which could cause motion between the wing and the fuselage and degrade the structural integrity of the wing attachment to the fuselage. This could lead to wing separation and loss of control of the airplane.
Airworthiness Directives; Hartzell Propeller Inc. ( )HC-( )2Y( )-( ) Series Propellers
The FAA is adopting a new airworthiness directive (AD) for Hartzell Propeller Inc. ( )HC-( )2Y( )-( ) series propellers with non- suffix serial number (SN) propeller hubs installed on Lycoming O-, IO-, LO-, and AEIO-360 series reciprocating engines. This AD requires initial and repetitive eddy current inspections (ECI) of the front cylinder half of the propeller hub for cracks and removing cracked hubs from service before further flight. In addition, this AD allows installation of an improved design propeller hub (suffix SN ``A'' or ``B'') as terminating action to the repetitive ECI. This AD results from a report of a propeller blade separating from a propeller hub. We are issuing this AD to prevent failure of the propeller hub causing blade separation and subsequent loss of airplane control.
Airworthiness Directives; Saab Model SAAB-Fairchild SF340A (SAAB/SF340A) and SAAB 340B Airplanes
This amendment adopts a new airworthiness directive (AD), applicable to certain Saab Model SAAB-Fairchild SF340A (SAAB/SF340A) and SAAB 340B airplanes, that requires modification and repetitive inspections of the hot detection system of the tail pipe harness of the engine nacelles. The actions specified by this AD are intended to prevent false warning indications to the flightcrew from the hot detection system due to discrepancies of the harness, which could result in an unnecessary aborted takeoff on the ground or in-flight engine shutdowns. This action is intended to address the identified unsafe condition.
Airworthiness Directives; Gulfstream Model GV and GV-SP Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Gulfstream Model GV and GV-SP series airplanes. This AD requires repairing the force link assembly wire harness. This AD results from a report indicating that the wiring harness outer shield and insulation on the primary conductors may have been inadvertently cut due to an improper method used to remove the wiring outer jacket. We are issuing this AD to prevent the loss of the hardover prevention system (HOPS) in the roll axis due to a short circuit in the wiring harness, which could result in reduced controllability of the airplane.
Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG Tay 650-15 and Tay 651-54 Turbofan Engines
The FAA is superseding an airworthiness directive (AD) for Rolls-Royce Deutschland Ltd & Co KG (RRD) Tay 650-15 and Tay 651-54 turbofan engines. That AD currently establishes cyclic life limits for certain part number (P/N) stage 1 high pressure turbine (HPT) discs and stage 1 low pressure turbine (LPT) discs operating under certain flight plan profiles. This AD requires calculating and re-establishing the achieved cyclic life of stage 1 HPT discs, P/N JR32013 or P/N JR33838, and stage 1 LPT discs, P/N JR32318A, that have been exposed to different flight plan profiles. This AD also requires removing from service those stage 1 HPT discs and stage 1 LPT discs operated under Tay 650-15 engine flight plan profiles A, B, C, and D, and operated under Tay 651-54 engine datum flight profile, at reduced cyclic life limits, using a drawdown schedule. This AD results from RRD updating their low-cycle-fatigue analysis for stage 1 HPT discs and stage 1 LPT discs and reducing their cyclic life limits. We are issuing this AD to prevent cracks leading to turbine disc failure, which could result in an uncontained engine failure and damage to the airplane.
Airworthiness Directives; Raytheon Aircraft Company Models 1900, 1900C, and 1900D Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Raytheon Aircraft Company (RAC) Models 1900, 1900C, and 1900D airplanes. This AD contains the same information as emergency AD 2006- 18-51 and publishes the action in the Federal Register. This AD requires you to do a one-time visual inspection of both the left and right wing rear spar lower caps for cracking and other damage such as loose or missing fasteners; repair any cracks or damage found; and report any cracks or damage found to the FAA and RAC. This AD results from extensive cracks found in the wing rear spar lower caps and rear spar web of two of the affected airplanes. One of the airplanes also had missing fasteners. We are issuing this AD to detect and correct cracking and other damage in the wing rear spar lower caps of the affected airplanes before the cracks or damage lead to failure. Such a wing failure could result in the wing separating from the airplane with consequent loss of control.

These procedures were modified in conjunction with the Midwest AirSpace Enhancement (MASE) project. The FAA is proposing this action to enhance safety and to improve the efficient use of the navigable airspace assigned to the Chicago and Cleveland Air Route Traffic Control Centers (ARTCC).
Finding of No Significant Impact
The Federal Aviation Administration (FAA) prepared an Environmental Assessment (EA) to evaluate the proposal from Blue Origin, LLC (Blue Origin) to construct and operate a commercial space launch site to be located on privately-owned property in Culberson County, Texas. Blue Origin proposes to develop this commercial space launch site to launch vertical reusable launch vehicles (RLVs) carrying space flight participants \1\ on suborbital, ballistic trajectories to altitudes in excess of 99,060 meters (325,000 feet) above sea level. The EA evaluated the potential environmental impacts of issuing experimental permits and/or licenses to Blue Origin authorizing vertical launches and landings of RLVs and/or operation of a launch site for same. Blue Origin may seek experimental permits to conduct early developmental and test flights. Blue Origin may also seek a launch site operator license, RLV mission-specific licenses, and RLV operator licenses, as appropriate. After reviewing and analyzing currently available data and information on existing conditions, project impacts, and measures to mitigate those impacts, the FAA, Office of Commercial Space Transportation (AST) has determined that issuing the experimental permits and/or licenses analyzed in the EA to Blue Origin would not significantly affect the quality of the human environment within the meaning of the National Environmental Policy Act (NEPA). Therefore the preparation of an Environmental Impact Statement (EIS) is not required and AST is issuing a Finding of No Significant Impact (FONSI). The FAA made this determination in accordance with all applicable environmental laws.

Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model ERJ 170 Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain EMBRAER Model ERJ 170 airplanes. This AD requires replacing the very high frequency (VHF) antenna located in position 1 of the fuselage with a new, improved VHF antenna. This AD results from a report of the loss of all voice communications due to a lightning strike damaging all the VHF antennas. We are issuing this AD to prevent the loss of voice communication, which, when combined with the complexity of the national airspace system, could result in reduced flightcrew situational awareness, increased flightcrew workload, and increased risk of human error, and consequent reduced ability to maintain safe flight and landing of the airplane.
Airworthiness Directives; Goodyear Aviation Tires, Part Number 217K22-1, Installed on Various Transport Category Airplanes, Including But Not Limited to Bombardier Model BD-700-1A10 and BD-700-1A11 Airplanes; and Gulfstream Model G-1159, G-1159A, G-1159B, G-IV, GIV-X, GV, and GV-SP Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain aviation tires installed on various transport category airplanes. This AD requires a one-time inspection of the nosewheel tires to determine if they are within a designated serial number range, and replacement if necessary. This AD results from reports of tread separations and tread-area bulges on the nosewheel tires. We are issuing this AD to prevent tread separation from a nosewheel tire during takeoff or landing, which could result in compromised nosewheel steering or ingestion of separated tread by an engine, and consequent reduced controllability of the airplane on the runway or in the air.
Airworthiness Directives; BAE Systems (Operations) Limited Model ATP Airplanes
The FAA is superseding an existing airworthiness directive (AD), which applies to all BAe Systems (Operations) Limited Model ATP airplanes. That AD currently requires revising the Airworthiness Limitations Section (ALS) of the Instructions for Continued Airworthiness (ICA) to incorporate life limits for certain items and inspections to detect fatigue cracking in certain structures; to incorporate new inspections to detect fatigue cracking of certain significant structural items (SSIs); and to revise life limits for certain equipment and various components. This new AD requires revising the ALS of the ICA to include additional and revised inspections of the fuselage. This AD results from the manufacturer review of fatigue test results that identified additional and revised inspections of the fuselage that are necessary in order to ensure the continued structural integrity of the airplane. We are issuing this AD to detect and correct fatigue cracking of certain structural elements, which could result in reduced structural integrity of the airplane and consequent rapid decompression of the airplane.
Airworthiness Directives; McDonnell Douglas Model DC-9-14, DC-9-15, and DC-9-15F Airplanes; Model DC-9-21 Airplanes; Model DC-9-30 Series Airplanes; Model DC-9-41 Airplanes; and Model DC-9-51 Airplanes
The FAA is superseding an existing airworthiness directive (AD), which applies to certain McDonnell Douglas Model DC-9-10, DC-9- 20, DC-9-30, DC-9-40, and DC-9-50 series airplanes. That AD currently requires a one-time inspection at a certain disconnect panel in the left forward cargo compartment to find contamination of electrical connectors and to determine if a dripshield is installed over the disconnect panel, and corrective actions if necessary. This new AD revises the applicability of the existing AD by removing certain airplanes and adding others. This AD results from a report of electrical arcing that resulted in a fire. We are issuing this AD to prevent contamination of certain electrical connectors, which could cause electrical arcing and consequent fire on the airplane.
Airworthiness Directives; Airbus Model A340-541 and -642 Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A340-541 and -642 airplanes. This AD requires a one-time inspection of the anti-stall valve sleeve of the ram air turbine (RAT) for proper installation, determining the part number of the modification plate on the hydraulic pump of the RAT, and follow-on corrective actions if necessary. This AD results from reports of failure of the anti-stall valve on the hydraulic pump of the RAT during scheduled ground tests. We are issuing this AD to prevent failure of the RAT hydraulic pump to supply adequate pressure to activate the RAT, and consequent loss of the RAT as a source of hydraulic and electrical power in an emergency situation.
Airworthiness Directives; Airbus Model A318, A319, A320, and A321 Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A318, A319, A320, and A321 airplanes. This AD requires revising the Limitations section of the airplane flight manual (AFM); performing a one-time hardness test of certain ribs of the left- and right-hand engine pylons, as applicable, which would terminate the AFM limitations; and performing related corrective actions if necessary. This AD results from a report that certain stainless steel ribs installed in the engine pylon may not have been heat-treated during manufacture, which could result in significantly reduced structural integrity of the pylon. We are issuing this AD to detect and correct reduced structural integrity of the engine pylon, which could lead to separation of the engine from the airplane.

Notice Concerning Airport Advisory Service at Certain Airports in the Continental United States, Excluding Alaska
The FAA is requesting public comment on the Airport Advisory Service provided at twenty (20) airports in the continental United States, excluding Alaska. The Airport Advisory Service, Local or Remote, is an optional service provided by Automated Flight Service Stations for pilots of landing or departing aircraft at airports either without air traffic control towers or with part-time control towers. The Airport Advisory Service information includes weather updates, wind and altimeter information, runway usage, aeronautical data, and any known air traffic in the area. Since Airport Advisory Service is provided full-time at many of the affected airports and part-time at others, with varying degrees of usage by the pilot community, it is important to obtain feedback from individual users and from user groups in order to ascertain the value of the service provided to the aviation community at those airports. The FAA is particularly interested in comments concerning the necessity of the service, the availability of the service, the importance of the service, and how often the service is used. Users are also welcome to include comments concerning any other aspect of your experience with Airport Advisory Service. The request for comments includes Airport Advisory Service at the following airports: Altoona-Blair County Airport (AOO), Altoona, Pennsylvania; Anderson Regional Airport (AND), Anderson, South Carolina; Anniston Metropolitan Airport (ANB), Anniston, Alabama; Casper-Natrona County International Airport (CPR), Casper, Wyoming; Cedar City Regional Airport (CDC), Cedar City, Utah; Columbia Regional Airport (COU), Columbia, Missouri; Elkins-Randolph Airport (EKN), Elkins, West Virginia; Gainesville Regional Airport (GNV), Gainesville, Florida; Grand Forks International Airport (GFK), Grand Forks, North Dakota; Greenwood-Leflore Airport (GWO), Greenwood, Mississippi; Huron Regional Airport (HON), Huron, South Dakota; Jackson-McKellar-Sipes Regional Airport (MKL), Jackson, Tennessee; Jonesboro Municipal Airport (JBR), Jonesboro, Arkansas; Louisville-Bowman Field Airport (LOU), Louisville, Kentucky; Macon-Middle Georgia Regional Airport (MCN), Macon, Georgia; Millville Municipal Airport (MIV), Millville, New Jersey; Prescott-Ernest A.

Airworthiness Directives; Bombardier Model DHC-8-400 Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Bombardier Model DHC-8-400 series airplanes. This proposed AD would require repetitive cleaning/inspecting of the drain hole of each pitot static probe and repetitive cleaning of the pitot lines in the pitot static system. This proposed AD results from reports of incidents of airspeed mismatch between the pilot, co-pilot, and standby airspeed indications caused by contamination in the pitot static system. We are proposing this AD to prevent erroneous/misleading altitude and airspeed information from a contaminated pitot static system to the flightcrew, which could reduce the ability of the flightcrew to maintain the safe flight and landing of the airplane.
Notice of Intent To Prepare an Environmental Impact Statement for the Southern Nevada Supplemental Airport, Clark County, NV, and To Conduct Public Scoping Meetings
The Federal Aviation Administration (FAA) and the Bureau of Land Management (BLM) are issuing this notice to the public that an Environmental Impact Statement (EIS) will be prepared to consider the construction and operation of a new supplemental commercial service airport in southern Nevada. In accordance with Public Law 106-362, titled: Ivanpah Valley Airport Public Lands Transfer Act, the FAA, representing the Department of Transportation (DOT), and the BLM, representing the Department of the Interior (DOI), will serve as joint lead Federal agencies for the preparation of this EIS. The Clark County Department of Aviation (CCDOA), the sponsor of the project, has proposed to construct and operate a new supplemental commercial service airport (the Ivanpah Valley Airport) 30 miles south of the Las Vegas metropolitan area in the Ivanpah Valley (the Proposed Action) in order to ensure sufficient commercial service capacity for the metropolitan area. CCDOA propose that the new supplemental commercial service airport would be operational by the year 2017, and would supplement existing capacity at McCarran International Airport (McCarran Airport). CCDOA's proposal to construct a supplemental airport requires approval by the FAA. Such Federal action is subject to the National Environmental Policy Act (NEPA) and requires preparation of an EIS, which will evaluate the environmental impacts of the proposed Ivanpah Valley Airport and other reasonable alternatives for meeting the aviation needs of southern Nevada. CCDOA has proposed to construct and operate a new supplemental commercial service airport in response to the need for supplemental commercial service to the Las Vegas metropolitan area. McCarran Airport, which is owned and operated by Clark County, is currently the primary commercial passenger and cargo airport that serves as a gateway to the Las Vegas metropolitan area and southern Nevada. The number of commercial service operations has increased substantially at McCarran Airport over the past decade, largely as a result of the rapid growth in tourism, convention business, and service industries associated with the gaming and entertainment industry in Las Vegas, as well as an increase in population. Forecasts predict continued growth in aircraft operations at rates significantly exceeding the national average. Although McCarran Airport will be able to accommodate passenger demand in the next few years with the planned expansion and development of new terminal facilities, parking lots, and roadways, FAA forecasts indicate that by the year 2015, activity at McCarran Airport will reach 706, 684 annual aircraft operations (takeoffs or landings), representing an approximate 15 percent increase over existing operations. Without additional airfield, roadway, and terminal capacity, this level of operations would result in unacceptable levels of congestion and delay. Therefore, additional airfield, roadway, and terminal facilities would be required to meet future operations and passenger demand in the region.
Revisions to Digital Flight Data Recorder Regulations for Boeing 737 Airplanes and for Part 125 Operators
The FAA is revising a previous proposal to increase the number of digital flight data recorder (DFDR) parameters required for all Boeing 737 series airplanes. Based on safety recommendations from the National Transportation Safety Board (NTSB) following the investigations of two accidents and other incidents involving 737s, the FAA proposed the addition of flight recorder equipment to monitor the rudder system on 737s. Since that time, the FAA has mandated significant changes to the rudder system on these airplanes. Accordingly, this new proposed rule would apply to a different set of airplanes than originally anticipated. We are requesting comment on this change in applicability and are requesting updated economic information regarding installation of the proposed monitoring equipment. The original proposed rule also sought to amend the flight data recorder (FDR) requirements of part 125 that would affect all airplanes operated under that part or under deviation from that part; we have included that same proposal in this SNPRM.
Airworthiness Directives; Bombardier Model CL-600-2B16 (CL-604) Airplanes and Model CL-600-2B19 (Regional Jet Series 100 & 440) Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Bombardier Model CL-600-2B16 (CL- 604) airplanes and Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. These models may be referred to by their marketing designations as RJ100, RJ200, CRJ100, CRJ200, and CL-65. This AD requires revising the Emergency Procedures section of the airplane flight manual (AFM) to advise the flightcrew of additional procedures to follow in the event of stabilizer trim runaway. For certain airplanes, this AD also requires revising the Abnormal Procedures section of the AFM to advise the flightcrew of procedures to follow in the event of MACH TRIM, STAB TRIM, and horizontal stabilizer trim malfunctions. This AD results from reports of uncommanded horizontal stabilizer trim motion. We are issuing this AD to ensure that the flightcrew is advised of appropriate procedures to follow in the event of stabilizer trim runaway. Failure to follow these procedures could result in excessive uncommanded movement of the horizontal stabilizer trim actuator (HSTA) and loss of ability to use trim switches to override uncommanded movement or yoke disconnect switches to disconnect the HSTA, which could result in reduction of or loss of pitch trim control and consequent reduced controllability of the airplane.
Airworthiness Directives; Agusta S.p.A. Model AB139 Helicopters
This document publishes in the Federal Register an amendment adopting Airworthiness Directive (AD) 2006-17-51, sent previously to all known U.S. owners and operators of Agusta S.p.A. (Agusta) Model AB139 helicopters by individual letters. This AD requires, before further flight and at specified intervals, certain visual inspections of each tailpipe assembly for a crack and for overheating. If you find areas of overheating, this AD also requires, before further flight, certain inspections for damage to the surrounding structure, outside of the cowling, and inside of each tailpipe assembly in certain areas. This AD also requires, before further flight, if you find a crack, replacing the tailpipe assembly with an airworthy tailpipe assembly. This AD is prompted by several reports of tailpipe assembly cracks. The actions specified by this AD are intended to prevent a fire due to the structure in the cowling area overheating, separation of a part of a tailpipe assembly, and subsequent loss of control of the helicopter.
Airspace Designations; Incorporation by Reference
This action amends Title 14 Code of Federal Regulations (14 CFR) part 71 relating to airspace designations to reflect the approval by the Director of the Federal Register of the incorporation by reference of FAA Order 7400.9P, Airspace Designations and Reporting Points. This action also explains the procedures the FAA will use to amend the listings of Class A, B, C, D, and E airspace areas; air traffic service routes; and reporting points incorporated by reference.
Standard Airworthiness Certification of New Aircraft
This final rule amends FAA regulations for issuing airworthiness certificates to certain new aircraft manufactured in the United States. These changes are necessary because under the current regulations, certain new aircraft are eligible for a standard airworthiness certificate without meeting the requirements of a type certificate (TC) and without having been manufactured under an FAA production approval. These changes are intended to ensure that new aircraft manufactured in the United States and issued a standard airworthiness certificate are type certificated and manufactured under an FAA production approval. This final rule also incorporates requirements contained in laws recently passed by Congress. These changes ensure that any person who manufactures or alters an aircraft, aircraft engine, or propeller based on a TC or supplemental type certificate (STC) either holds the certificate or has permission from the certificate holder. This amendment also includes language that allows a person to manufacture one new aircraft based on a TC without holding the TC or having a licensing agreement from the TC holder, provided manufacture of the aircraft began before August 5, 2004.
