Airworthiness Directives; DASSAULT AVIATION Airplanes
We propose to adopt a new airworthiness directive (AD) for certain DASSAULT AVIATION Model FALCON 900EX airplanes. This proposed AD was prompted by our determination of the need for a revision to the airplane airworthiness limitations to introduce a corrosion prevention control program, among other changes, to the maintenance requirements and airworthiness limitations. This proposed AD would require revising the maintenance or inspection program, as applicable, to include the maintenance tasks and airworthiness limitations specified in the Airworthiness Limitations section of the airplane maintenance manual. We are proposing this AD to prevent reduced structural integrity of the airplane, and prevent reduced controllability of the airplane.
MAP-21 Section 1306 Financial Penalties Guidance
The Federal Highway Administration (FHWA) and the Federal Transit Administration (FTA) are issuing joint guidance on the implementation of the financial penalty provisions contained in Section 1306 of the Moving Ahead for Progress in the 21st Century Act (MAP-21). The financial penalty provisions require Federal agencies of jurisdiction (Reviewing Agency) to render a decision on a permit, license, or other approval related to a transportation project within 180 days from the later of the date FHWA or FTA issue a Record of Decision or Finding of No Significant Impacts for a project, or the date on which an application for a permit, license, or approval for the project is complete. If the Reviewing Agency does not render a decision by the 180-day deadline, it is subject to a rescission of funds of $10,000 or $20,000 per week until the Reviewing Agency renders a decision. The FHWA and FTA have the authority to grant ``no-fault'' certifications if the Reviewing Agency's failure to decide was due to circumstances beyond its control. You may review the guidance by visiting FHWA's Web site at https://www.fhwa.dot.gov/map21, or FTA's Web site at https://www/fta.dot.gov/map21.
Revisions to Passenger Train Emergency Preparedness Regulations
FRA is amending its existing regulation entitled Passenger Train Emergency Preparedness by revising or clarifying various provisions. The final rule clarifies that railroad personnel who communicate or coordinate with first responders during emergency situations must receive certain initial and periodic training and be subject to operational tests and inspections related to the railroad's emergency preparedness plan. The final rule also clarifies that railroads must develop procedures in their emergency preparedness plans that specifically address the safety of passengers with disabilities during actual and simulated emergency situations, such as during train evacuations. The rule also limits the need for FRA to formally approve certain purely administrative changes to approved emergency preparedness plans. In addition, the final rule requires that operational tests and inspections be conducted in accordance with a program that meets certain minimum requirements. Finally, the rule removes as unnecessary the provision discussing the preemptive effect of the regulations.
Amendment to Class B Airspace Area; Detroit, MI
This action corrects a final rule published in the Federal Register January 21, 2014. In that rule, the shared boundary between the Detroit Class B airspace Area A and Area B subareas did not match, as originally intended, in the regulatory text descriptions. This correction is necessary to close the unintended gap between subareas created by the boundary error and to ensure the accuracy of the charted Detroit Class B airspace area.
Airworthiness Directives; Pratt & Whitney Turbofan Engines
We are adopting a new airworthiness directive (AD) for all Pratt & Whitney (PW) PW2037, PW2037D, PW2037M, PW2040, PW2040D, PW2043, PW2146, PW2240, PW2337, PW2643, and F117-PW-100 turbofan engines. This AD was prompted by a rupture of the diffuser-to-high-pressure turbine (HPT) case flange. This AD requires a one-time eddy current inspection (ECI) of affected engines with certain diffuser and HPT cases installed. This AD also requires a fluorescent-penetrant inspection (FPI) of the diffuser case rear flange and HPT case front flange. We are issuing this AD to prevent failure of the diffuser-to-HPT case flange, which could lead to uncontained engine failure and damage to the airplane.

Airworthiness Directives; Embraer S.A. Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Embraer S.A. Model ERJ 170 airplanes. This proposed AD was prompted by reports of ``BLEED 1(2) LEAK'' messages displayed on the Engine Indication and Crew Alert System (EICAS), and indirect damage to components of the Electrical Wiring Interconnection System (EWIS) in the engine pylon area. This proposed AD would require inspecting the EWIS components for damage, and repair if necessary. This proposed AD would also require installing pre-cooler deflectors on the left- and right-hand pylons, and applying silicone sealant. We are proposing this AD to prevent indirect damage to EWIS components near the engine bleed air pre-coolers, which could result in a dual engine roll back to idle and consequent dual engine power loss and reduced controllability of the airplane.
Airworthiness Directives; Bombardier, Inc. Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. This proposed AD was prompted by reports that elevator power control unit (PCU) shear pins may fail prematurely. This proposed AD would require repetitive replacement of the elevator PCU shear pins. We are proposing this AD to prevent PCU failure of elevator PCU sheer pins. If all pins fail on one elevator, the elevator surface would become inoperative, which could reduce the controllability of the airplane and could result in a loss of redundancy for flutter prevention.
Airworthiness Directives; the Boeing Company Airplanes
We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 787-8 airplanes. This proposed AD was prompted by a report indicating that, on a different Boeing airplane model, there was an oxygen-fed fire, which caused extensive damage to the flight deck. This proposed AD would require replacing the low- pressure oxygen hoses with non-conductive hoses in the crew oxygen system. We are proposing this AD to prevent inadvertent electrical current from passing through an internal, anti-collapse spring of the low pressure oxygen hose, which can cause the low-pressure oxygen hose to melt or burn, leading to an oxygen-fed fire and/or smoke beneath the flight compartment in the forward electronics equipment bay.
Airworthiness Directives; Airbus Airplanes
We propose to supersede Airworthiness Directive (AD) 2009-06- 06 for all Airbus Model A310 and A300-600 series airplanes. AD 2009-06- 06 currently requires revising the Airworthiness Limitations Section of the Instructions for Continued Airworthiness to incorporate new limitations and maintenance tasks for aging systems maintenance. Since we issued AD 2009-06-06, we have determined that more restrictive maintenance requirements and airworthiness limitations are necessary. This proposed AD would require revising the maintenance or inspection program to incorporate new maintenance requirements and airworthiness limitations. We are proposing this AD to prevent reduced structural integrity and reduced control of these airplanes due to the failure of system components.
Notice of Final Federal Agency Actions on Proposed Highways in Texas
This notice announces actions taken by the FHWA and other Federal agencies that are final within the meaning of 23 U.S.C. 139(l)(1). The actions relate to a proposed highway project, State Highway (SH) 360 from East Sublett Road/West Camp Wisdom Road to U.S. Highway 287 in the counties of Tarrant, Ellis, and Johnson in the State of Texas. Those actions grant licenses, permits, and approvals for the projects.
Airworthiness Directives; The Boeing Company Airplanes
We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 727 airplanes. This AD will 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 AD requires repetitive inspections for cracking of small repairs done on the vertical flange of the rib chord, repetitive inspections for cracking along the upper fillet radius of the rib chord, and a large repair or preventive modification if necessary. Accomplishment of a large repair or preventive modification terminates the actions of this AD. We are issuing this AD to prevent cracks in the rib upper chord, which could result in the inability of the wing structure to support the limit load condition, and consequent loss of structural integrity of the wing.
Airworthiness Directives; Airbus Helicopters (Type Certificate Previously Held by Eurocopter France) (Airbus Helicopters)
We are superseding Airworthiness Directive (AD) 2012-25-04 for Eurocopter France Model AS350B3 helicopters with a certain modification (MOD) installed. AD 2012-25-04 required installing two placards and revising the Rotorcraft Flight Manual (RFM). AD 2012-25-04 also required certain checks and inspecting and replacing, if necessary, all four laminated half-bearings (bearings). This new AD retains the previous AD requirements, requires certain modifications which would be terminating action for the airspeed limitations, and adds certain helicopter models to the bearing inspection with a different inspection interval. These actions are intended to prevent vibration due to a failed bearing, failure of the tail rotor, and subsequent loss of control of the helicopter.
Highway Safety Improvement Program
The purpose of this notice of proposed rulemaking (NPRM) is to propose changes to Highway Safety Improvement Program (HSIP) regulations to address provisions in the Moving Ahead for Progress in the 21st Century Act (MAP-21) as well as to incorporate clarifications to better explain existing regulatory language. Specifically, this rule proposes to amend DOT's regulations to address MAP-21 provisions that removed the requirement for States to prepare a Transparency Report, removed the High Risk Rural Roads set-aside, and removed the 10 percent flexibility provision for States to use safety funding in accordance with federal law. This rule also proposes to amend DOT's regulations to address a MAP-21 provision that requires DOT to establish a subset of roadway data elements that are useful to the inventory of roadway safety, and to ensure that States adopt and use the subset. Finally, this rule proposes to address MAP-21 provisions that add State Strategic Highway Safety Plan update requirements and require States to develop HSIP performance targets. The proposed changes are intended to clarify the regulation for the development, implementation, and evaluation of highway safety improvement programs that are administered in each State.
Airworthiness Directives; Bombardier, Inc. Airplanes
We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model DHC-8 airplanes. This AD requires repetitive functional checks of the nose and main landing gear, and corrective actions if necessary. This AD also provides optional terminating action for the repetitive functional checks. This AD was prompted by a report that the emergency downlock indication system (EDIS) had given a false landing gear down-and-locked indication. We are issuing this AD to detect and correct a false down-and-locked landing gear indication, which, on landing, could result in possible collapse of the landing gear.
Airworthiness Directives; The Boeing Company Airplanes
We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 787-8 airplanes. This proposed AD was prompted by failure of the anchor attachment on the occupant restraint system on the standard attendant seat due to an undersized attachment fitting. This proposed AD would require replacing the existing restraint attachment fitting on the standard attendant seat with a new, improved attachment fitting. We are proposing this AD to prevent failure of the restraint attachment fitting and consequent detachment of the attendant seat during an emergency landing, which could cause injury to passengers and crew and could impede a rapid evacuation.
Airworthiness Directives; Bombardier, Inc. Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model DHC-8-400 series airplanes. This proposed AD was prompted by fuel system reviews conducted by the manufacturer. This proposed AD would require replacing a fitting that is part of the refuel control solenoid valve assembly. We are proposing this AD to prevent the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.
Airworthiness Directives; SOCATA Airplanes
We are adopting a new airworthiness directive (AD) for SOCATA Model TBM 700 airplanes. This 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 landing gear actuator rod and piston becoming unscrewed during operation and the landing gear actuator ball joint becoming uncrimped. We are issuing this AD to require actions to address the unsafe condition on these products.
Airworthiness Directives; British Aerospace Regional Aircraft Airplanes
We are adopting a new airworthiness directive (AD) for British Aerospace Regional Aircraft Jetstream Series 3101 and Jetstream Model 3201 airplanes. This 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 stress corrosion cracking of the main landing gear yoke pintle housing on a Jetstream series 3100 airplane. We are issuing this AD to require actions to address the unsafe condition on these products.
Airworthiness Directives; Bombardier Inc., Airplanes
We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model DHC-8-102, -103, -106, -201, -202, -301, -311, and -315 airplanes. This AD was prompted by results from fuel system reviews conducted by the manufacturer. This AD requires accomplishing modifications to the fuel system. We are issuing this AD to prevent the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.
Electronic Logging Devices and Hours of Service Supporting Documents
The Federal Motor Carrier Safety Administration (FMCSA) proposes amendments to the Federal Motor Carrier Safety Regulations (FMCSRs) to establish: Minimum performance and design standards for hours-of-service (HOS) electronic logging devices (ELDs); requirements for the mandatory use of these devices by drivers currently required to prepare HOS records of duty status (RODS); requirements concerning HOS supporting documents; and measures to address concerns about harassment resulting from the mandatory use of ELDs. This rulemaking supplements the Agency's February 1, 2011, Notice of Proposed Rulemaking (NPRM) and addresses issues raised by the U.S. Court of Appeals for the Seventh Circuit in its 2011 decision vacating the Agency's April 5, 2010, final rule concerning ELDs as well as subsequent statutory developments. The proposed requirements for ELDs would improve compliance with the HOS rules.
Airworthiness Directives; The Boeing Company Airplanes
We are superseding Airworthiness Directive (AD) 2008-08-25 that applied to certain The Boeing Company Model 747-400 and 747-400F series airplanes. AD 2008-08-25 required installing drains and drain tubes to eliminate water accumulation in the drip shield above the M826 cardfile in the main equipment center. This new AD requires installing modified drain tubes, relocating wire bundle routing, installing a new drip shield and drip shield deflectors, and replacing insulation blankets. For certain airplanes, this new AD also concurrently requires sealing the drain slot, installing spuds, and installing drain tubes. This AD was prompted by reports of continued water damage to diode fire card 285U0072-1 in the M826 automatic fire overheat logic test system cardfile following a false FWD CARGO FIRE message, with no change in frequency, which resulted in an air turn back. We are issuing this AD to prevent water from exiting over the edge of the existing drip shield and contaminating electrical components in the M826 cardfile, which could result in an electrical short and potential loss of several functions essential for safe flight.
Airworthiness Directives; Rockwell Collins, Inc. Transponders
We are adopting a new airworthiness directive (AD) for certain Rockwell Collins TPR-720 and TPR-900 Mode select (S) transponders that are installed on airplanes. This AD was prompted by the identification that the TPR-720 and TPR-900 Mode S transponders respond intermittently to Mode S interrogations from both ground-based and traffic collision avoidance system (TCAS-) equipped airplanes. This AD requires testing and calibration of the alignment of the transponders. We are issuing this AD to correct the unsafe condition on these products.
