Federal Motor Vehicle Theft Prevention Standard; Final Listing of 2014 Light Duty Truck Lines Subject to the Requirements of This Standard and Exempted Vehicle Lines for Model Year 2014
This final rule announces NHTSA's determination that there are no new model year (MY) 2014 light duty truck lines subject to the parts-marking requirements of the Federal motor vehicle theft prevention standard because they have been determined by the agency to be high-theft or because they have a majority of interchangeable parts with those of a passenger motor vehicle line. This final rule also identifies those vehicle lines that have been granted an exemption from the parts-marking requirements because the vehicles are equipped with antitheft devices determined to meet certain statutory criteria.
Airworthiness Directives; Sikorsky Aircraft Corporation (Sikorsky) Helicopters
We propose to adopt a new airworthiness directive (AD) for Sikorsky Model S-70, S-70A, and S-70C helicopters. This proposed AD would establish a new life limit based on a prorated formula for certain identified components (parts) installed on Model S-70, S-70A, and S-70C helicopters after being previously installed on certain military model helicopters. This proposed AD is prompted by the discovery that certain parts have been interchanged between military helicopter models with different life limits and the possibility that these same parts can be interchanged with civilian models with different life limits. The proposed actions are intended to establish a pro-rated in service life limit for each identified part to prevent fatigue failure of a part and subsequent loss of control of the helicopter.
Airworthiness Directives; Eurocopter France Helicopters
We propose to adopt a new airworthiness directive (AD) for Eurocopter France (Eurocopter) Model EC225LP helicopters. This proposed AD would require inspecting the swashplates for corrosion or a crack, and making the appropriate repairs or replacement of parts. This proposed AD is prompted by the discovery of corrosion on the swashplates when the main rotor hub (MRH) assemblies were reconditioned. The proposed actions are intended to detect corrosion or a crack in the swashplates, which could lead to failure of the swashplate and subsequent loss of helicopter control.
Airworthiness Directives; Sikorsky Aircraft Corporation (Sikorsky) Model Helicopters
We are revising an earlier proposed airworthiness directive (AD) for the Sikorsky Model S-70, S-70A, S-70C, S-70C (M), and S-70C (M1) helicopters with General Electric (GE) T700-GE-401C or T700-GE- 701C engines installed, which proposed establishing new fatigue life limits for certain GE engine gas generator turbine (GGT) rotor parts. The proposed AD was prompted by a reevaluation of the method for determining the life limit for certain GE engine gas generator turbine (GGT) rotor parts and the determination that these life limits need to be based on low cycle fatigue (LCF) events instead of hours time-in- service. This action would retain the previously proposed requirements but correct the life limit formula for a certain GGT rotor part. The proposed actions are intended to prevent fatigue failure of a GGT rotor part, engine failure, and subsequent loss of control of the helicopter.
Airworthiness Directives; Eurocopter Deutschland GmbH Helicopters
We propose to adopt a new airworthiness directive (AD) for Eurocopter Deutschland GmbH (Eurocopter) Model MBB-BK 117 C-2 helicopters with a jettisonable sliding door (door) installed. This proposed AD would require inspecting the lock release assembly and the middle and upper lever locking bolts of each door, replacing any damaged parts with airworthy parts, and ensuring the door is correctly installed. This proposed AD is prompted by the uncommanded detaching of a door from an MBB-BK 117 C-2 fuselage. The proposed actions are intended to prevent the in-flight loss of the door, which could damage the helicopter and injure persons on the ground.
Airworthiness Directives; Agusta S.p.A. Helicopters (Type Certificate Currently Held By AgustaWestland S.P.A) (AgustaWestland)
We propose to adopt a new airworthiness directive (AD) for AgustaWestland Model A109S, AW109SP, A119, and AW119 MKII helicopters to require removing certain rod end assemblies from service. This proposed AD is prompted by reports of fractures on the rod end assemblies that could damage the main rotor assembly and lead to loss of control of the helicopter.

Airworthiness Directives; Hamilton Sundstrand Corporation Propellers
The FAA is withdrawing a notice of proposed rulemaking (NPRM). The NPRM proposed a new airworthiness directive (AD) that had applied to certain Hamilton Sundstrand Corporation 14SF-7, 14SF-15, and 14SF-23 series propellers. The NPRM had applied to those propellers using certain Hamilton Sundstrand Corporation auxiliary pumps and motors (auxiliary feathering pumps). The proposed action would have required removal of certain serial numbers (S/Ns) of auxiliary feathering pumps from service. Since we issued the NPRM, we attended a meeting sponsored by Hamilton Sundstrand Corporation, which provided additional information regarding the unsafe condition. The information included results from bond strength tests that predicts a significantly lower fleet risk than the prior qualitative analysis. Accordingly, we withdraw the proposed rule.
Modification of Class B Airspace; Las Vegas, NV

Standard Instrument Approach Procedures, and Takeoff Minimums and Obstacle Departure Procedures; Miscellaneous Amendments
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.
Airworthiness Directives; the Boeing Company
We propose to supersede an existing airworthiness directive (AD) that applies to certain The Boeing Company Model 747 series airplanes. The existing AD currently requires repetitive detailed inspections to detect cracking in certain fuselage upper deck tension ties, repair or modification of any cracked tension ties, and repetitive inspections of repaired and modified tension ties and repair or modification if necessary. The existing AD also provides for optional terminating action for the repetitive detailed inspections of tension ties that have not been repaired or modified. This proposed AD was prompted by an evaluation by the design approval holder indicating that the upper deck tension ties of the fuselage are subject to widespread fatigue damage. This proposed AD would retain the repetitive inspections, mandate the previously optional terminating modification, and add, for tension ties that have not been repaired or modified, repetitive inspections that must be done concurrently with the existing repetitive inspections. We are proposing this AD to prevent widespread fatigue damage of certain fuselage upper deck tension ties, which could result in reduced structural integrity of the airplane.
Standard Instrument Approach Procedures, and Takeoff Minimums and Obstacle Departure Procedures; Miscellaneous Amendments

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.
Airworthiness Directives; Bombardier, Inc. Airplanes
We are superseding airworthiness directive (AD) 2011-13-08 for certain Bombardier, Inc. Model DHC-8-400 series airplanes. AD 2011-13- 08 required a free-play check for excessive free-play of the shaft swaged bearing installed in the tailstock end of each elevator power control unit (PCU), and replacing any PCU on which the bearing exceeds allowable limits with a serviceable PCU. This new AD adds airplanes to the applicability from that of AD 2011-13-08. This AD was prompted by a determination that additional airplanes are affected by the identified unsafe condition. We are issuing this AD to detect and correct excessive free-play of the swaged bearings, which could lead to excessive airframe vibrations and difficulties in pitch control, and consequent loss of controllability of the airplane.
Airworthiness Directives; The Boeing Company Airplanes
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 747-400 and 747-400F series airplanes. This AD was prompted by reports of cracking in the outboard flange of the longeron extension fittings, which attach to the wing-to-body fairing support frame. This AD requires repetitive inspections of the longeron extension fittings for cracking, and corrective actions if necessary. We are issuing this AD to detect and correct cracks in the longeron extension fittings, which can become large and adversely affect the structural integrity of the airplane.
Airworthiness Directives; The Boeing Company Airplanes
We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 727 airplanes. This AD was prompted by reports of cracks on the elevator rear spar stiffener assembly. This AD requires repetitive detailed inspections for cracking of the elevator rear spar stiffener assembly, and corrective actions if necessary. We are issuing this AD to detect and correct cracking of the elevator rear spar stiffener assembly, which could adversely affect elevator structural stiffness, which could lead to elevator vibration and possible interference with the tab control rod. These conditions could result in flutter and consequent loss of control of the airplane.
Airworthiness Directives; Learjet Inc. Airplanes
We are adopting a new airworthiness directive (AD) for certain Learjet Inc. Model 45 airplanes. This AD was prompted by a report that the fire barrier seal on the external baggage door does not seal the surrounding door structure due to incorrect positioning of the barrier. This AD requires modifying the fire seal on the baggage door, including doing inspections of the fire seal for correct contact and corrective action if necessary. We are issuing this AD to prevent improper sealing of the baggage door, which could increase the risk of an uncontained fire in the baggage compartment.
Airworthiness Directives; The Boeing Company Airplanes
We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 727 airplanes. This AD was prompted by reports of spanwise cracks and corrosion in the wing center box upper skin and rear spar upper chord between left buttock line (LBL) 70.50 and right buttock line (RBL) 70.50 at body station (STA) 870. This AD requires repetitive inspections of the wing center box for cracking around certain fastener rows on the rear spar upper chord horizontal flange; for certain airplanes, repetitive inspections for cracking of the rear spar upper chord radius; for certain other airplanes, repetitive inspections for damage, cracking, and corrosion of the pressure seal; and repair if necessary. We are issuing this AD to detect and correct cracking and corrosion of the upper skin and rear spar upper chord of the wing center box, which could result in loss of the airplane wing and consequent loss of control of the airplane.
Use of Wireless Mobile Data Devices as Transponders for the Commercial Motor Vehicle Information Systems and Networks (CVISN) Electronic Screening Systems
FMCSA announces that Commercial Mobile Radio Services (CMRS) network devices can be used as transponders for the purposes of CVISN electronic screening truck inspection and weigh station bypass systems. CMRS network devices such as smartphones, tablets, fleet management systems, global positioning system (GPS) navigational units, and onboard telematics devices (referred to collectively as ``wireless mobile data devices'') have the capability of transmitting and receiving the same information between the driver and the inspection site as the dedicated short-range communication (DSRC)-enabled transponders operating at the 915 MHz frequency currently used to fulfill the CVISN electronic screening requirement for core compliance. This policy does not affect the applicability or enforcement of FMCSA's regulations prohibiting texting and the use of hand-held wireless mobile phones by commercial motor vehicle (CMV) drivers.

The Department of Transportation (DOT) invites public comments on a request to the Office of Management and Budget (OMB) to approve an Emergency Information Collection Request in accordance with the requirements of the Paperwork Reduction Act of 1995 (Pub. L. 104-13, 44 USC 3501 et seq). This request is being submitted to OMB via an Emergency Information Collection Request. On July 6, 2012, the President of the United States signed the Moving Ahead for Progress in the 21st Century Act of 2012 (MAP-21). MAP-21 authorized $750 million in FY 2013 and $1 billion in FY 2014 for the Transportation Infrastructure Financing and Innovation Act (TIFIA) program to pay the subsidy cost of supporting Federal credit. The TIFIA program will provide Federal credit assistance in the form of direct loans, loan guarantees, and standby lines of credit to eligible surface transportation projects. This information collection relates to the collection of information from entities interested in TIFIA credit assistance and assists the DOT in evaluating projects and project sponsors for program eligibility and creditworthiness.
Technical Operations Safety Action Program (T-SAP) and Air Traffic Safety Action Program (ATSAP)
The FAA is proposing that safety information provided to it under the T-SAP, established in Notice JO 7210.807 which will be incorporated in FAA Order JO 7200.20, Voluntary Safety Reporting Programs, and ATSAP, covered by FAA Order JO 7200.20, be designated by an FAA Order as protected from public disclosure in accordance with the provisions of 14 CFR part 193, Protection of Voluntarily Submitted Information. The designation is intended to encourage persons to voluntarily provide information to the FAA under the T-SAP and ATSAP, so the FAA can learn about and address aviation safety hazards of which it was unaware or more fully understand and implement corrective measures for events or safety issues known by it through other means. Under 49 U.S.C. 40123, Protection of Voluntarily Submitted Information, the FAA is required to protect information from disclosure to the public, including disclosure under the Freedom of Information Act (5 U.S.C. 552) or other laws, following the issuance of such Order.
Paperless Hazard Communications Pilot Program
PHMSA invites volunteers for a pilot program to evaluate the effectiveness of paperless hazard communications systems and comments on an information collection activity associated with the pilot program. ``Moving Ahead for Progress in the 21st Century Act'' (MAP-21) authorizes PHMSA to conduct a pilot program to evaluate the feasibility and effectiveness of using paperless hazard communications systems. In accordance with MAP-21, in conducting the pilot projects, PHMSA may not waive the current shipping paper requirements. In addition, MAP-21 indicates that PHMSA must consult with organizations representing fire and other emergency responders, law enforcement, and regulated entities. Upon completion of the pilot projects, PHMSA must evaluate the feasibility and effectiveness of paperless hazard communications systems and make a recommendation to Congress regarding regulatory changes that would permanently authorize the use of paperless hazard communications systems. The report is due to Congress by October 1, 2014. The intent of this notice is to: (1) Describe the current regulatory requirements for shipping papers; (2) describe authority granted under MAP-21; (3) explain the goal, scope, and intent of the pilot program; (4) seek volunteers to participate in the pilot projects and describe criteria for selecting pilot participants from the volunteers; and (5) seek comment on the request for information to be collected in conducting the pilot projects and in consulting with organizations representing fire and other emergency responders, law enforcement, and regulated entities.

Airworthiness Directives; ATR-GIE Avions de Transport Régional Airplanes
We propose to adopt a new airworthiness directive (AD) for certain ATR-GIE Avions de Transport R[eacute]gional Model ATR72-101, - 201, -102, -202, -211, -212, and -212A airplanes. This proposed AD was prompted by reports of airplane incidents and accidents that have occurred because of low-level fuel tank situations and fuel starvation that resulted in engine flameouts. This proposed AD would require installing a fuel quantity indicator (FQI) equipped with a locking adaptor on the electrical connector. We are proposing this AD to prevent an engine flame-out, which could result in reduced controllability of the airplane.
Airworthiness Directives; Bombardier, Inc. Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model BD-700-1A11 airplanes. This proposed AD was prompted by a report that certain lanyards for the passenger oxygen masks are longer than the specified length, possibly leading to inactive oxygen masks in an emergency. This proposed AD would require replacing certain oxygen mask lanyards. We propose this AD to detect and correct lanyards of incorrect length, which might not activate the flow of oxygen in an emergency, resulting in injury to passengers.
Membership Availability in the National Parks Overflights Advisory Group Aviation Rulemaking Committee
The National Park Service (NPS) and the Federal Aviation Administration (FAA), as required by the National Parks Air Tour Management Act of 2000, established the National Parks Overflights Advisory Group (NPOAG) in March 2001. The NPOAG was formed to provide continuing advice and counsel with respect to commercial air tour operations over and near national parks. This notice informs the public of two vacancies on the NPOAG [now the NPOAG Aviation Rulemaking Committee (ARC)] for members representing commercial air tour operators (one vacancy) and environmental concerns (one vacancy) and invites interested persons to apply to fill the vacancies.
Airworthiness Directives; The Boeing Company Airplanes
We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 727-200 and 727-200F series airplanes. This proposed AD is intended to complete certain mandated programs intended to support the airplane reaching its limit of validity (LOV) of the engineering data that support the established structural maintenance program. This proposed AD would require a one-time inspection for cracking of the pressure floor of both main wheel wells, and related investigative and corrective actions if necessary; and would require modifying the pressure floor of both main wheel wells. We are proposing this AD to prevent fatigue cracking in the pressure floor of the main wheel wells, which could lead to rapid loss of cabin pressurization.
Airworthiness Directives; The Boeing Company Airplanes
We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 727 airplanes. This proposed AD is intended to complete certain mandated programs intended to support the airplane reaching its limit of validity (LOV) of the engineering data that support the established structural maintenance program. This proposed AD would require an inspection for cracks in the main wheel well pressure floor and a preventive modification or permanent repair, as applicable. We are proposing this AD to prevent cracking in the main wheel well pressure floor, which could result in reduced structural integrity of the airplane, and decompression of the cabin.
