Airworthiness Directives; Fokker Model F.28 Mark 1000, 2000, 3000, and 4000 Airplanes
The FAA is adopting a new airworthiness directive (AD) for all Fokker Model F.28 Mark 1000, 2000, 3000, and 4000 airplanes. This AD requires a one-time inspection of the left- and right-hand main landing gear (MLG) downlock actuators or a review of the airplane maintenance records to determine the part number of each downlock actuator installed, and replacement of identified MLG downlock actuators with modified MLG downlock actuators. This AD results from a report of a failed downlock actuator, which resulted in the left MLG collapsing during taxi after landing. We are issuing this AD to prevent failure of the downlock actuator, which could prevent the MLG side stay from locking properly, resulting in collapse of the MLG during ground maneuvers or upon landing.
Airworthiness Directives; Construcciones Aeronauticas, S.A., (CASA) Model C-212 Airplanes
We are adopting a new 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 follows:
Airworthiness Directives; Alpha Aviation Design Limited R2160 Airplanes
We are adopting a new airworthiness directive (AD) for the products listed above. 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 a deficiency in compliance with 14 CFR 23.967(d). There have been instances indicating that production aircraft may not have a metal barrier between the cabin and the fuel tank bay. Lack of a barrier could allow flammable fuel vapors to enter the cabin. We are issuing this AD to require actions to correct the unsafe condition on these products.
Airworthiness Directives; Fokker Model F.28 Mark 0070 and 0100 Airplanes
The FAA is adopting a new airworthiness directive (AD) for all Fokker Model F.28 Mark 0070 and 0100 airplanes. This AD requires a one- time inspection of the fuel lines located in the left and right main landing gear (MLG) bays to determine the clearance between the fuel and hydraulic lines. If necessary, this AD also requires an inspection of fuel lines for chafing, the replacement of a chafed fuel line with a new fuel line, and the repositioning of existing clamps and installation of additional clamps between the fuel and hydraulic lines. This AD results from a fuel leak found in the left MLG bay. We are issuing this AD to detect and correct inadequate clearance between fuel and hydraulic lines in the MLG bay, which could lead to chafing of a fuel line and fuel leakage. A fuel leak near hot brakes could result in a fire in the MLG bay.
Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model ERJ 170-100 LR, -100 STD, -100 SE, -100 SU, -200 LR, -200 STD, and -200 SU Airplanes and Model ERJ 190 Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain EMBRAER Model ERJ 170-100 LR, -100 STD, -100 SE, -100 SU, -200 LR, -200 STD, and -200 SU airplanes and Model ERJ 190 airplanes. This AD requires inspecting to determine the part number and serial number of the deployment actuator of the ram air turbine (RAT) and related investigative and corrective actions if necessary. This AD results from reports that the RAT may not fully deploy due to galling between the piston rod and gland housing of the RAT deployment actuator. We are issuing this AD to prevent the RAT from failing to deploy, which could result in loss of control of the airplane during in-flight emergencies.
Airworthiness Directives; Fokker Model F.28 Mark 0070 and 0100 Airplanes
The FAA is superseding an existing airworthiness directive (AD), which applies to certain Fokker Model F.28 Mark 0070 and 0100 airplanes. That AD currently requires a one-time inspection of the sliding members in the main landing gear (MLG) for cracking and replacement of the sliding members with serviceable parts if necessary. This new AD adds repetitive magnetic particle inspections of the sliding members of the MLG for cracking and corrective actions as necessary. This AD results from inspection findings that have shown repetitive inspections are needed to establish fleet safety. We are issuing this AD to detect and correct fatigue cracking of the sliding member, which could result in possible separation of the MLG from the airplane and consequent reduced controllability of the airplane upon landing and possible injury to passengers.
Airworthiness Directives; Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. This AD requires repetitive inspections of the bolts that attach the exhaust nozzle to the aft engine flange to determine if any bolts are missing or fractured, and replacement of the existing bolts with new, improved bolts. This AD results from reports of the engine exhaust nozzle and fairing departing from the airplane in flight due to missing attachment bolts. We are issuing this AD to detect and correct missing or fractured attachment bolts, which could lead to the loss of an engine exhaust nozzle during flight and consequent structural damage to the airplane and hazard to people or property on the ground. Damage to the airplane could cause the airplane to yaw and result in reduced controllability of the airplane.
Airworthiness Directives; Bombardier Model DHC-8-102, -103, and -106 Airplanes; and Model DHC-8-200 and DHC-8-300 Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Bombardier Model DHC-8-100 (as described above), DHC-8-200, and DHC-8-300 series airplanes. This AD requires doing a one-time inspection for damage of the electrical cable harness assembly located on the left and right wing root-to-fuselage aft seal, and repair if necessary; and reworking the fuselage aft seal assembly (left and right) to create a clearance between the electrical cable assemblies and the edge of the fairing panel. This AD results from a report that an airplane encountered an uncommanded propeller feathering during climb, which resulted in an emergency landing. We are issuing this AD to prevent chafing or grounding of the wiring against the aft seal assemblies, which, if not corrected, could interrupt the operation of various systems, including the propeller feather control, alternating current (AC) electrical power, and standby hydraulic power, and result in reduced controllability of the airplane.
Airworthiness Directives; Airbus Model A300 B2 and B4 Series Airplanes
The FAA is superseding an existing airworthiness directive (AD), which applies to all Airbus Model A300 B2, B4-100, and B4-200 series airplanes. That AD currently requires supplemental structural inspections to detect fatigue cracking, and repair of cracked structure. This new AD requires revising the maintenance program by incorporating new and revised supplemental structural inspections, inspection intervals, and repairs; and repair of any damaged, cracked, or corroded structure; which would end the existing supplement structural inspections. This AD results from a review of service history and reports received from the current supplemental structural inspection document program. We are issuing this AD to prevent reduced structural integrity of these airplanes due to fatigue cracking.

The purpose of this request for comments is to acquire new and updated information regarding vehicle manufacturers' future product plans to aid in implementing the President's plan for reforming and increasing corporate average fuel economy (CAFE) standards for passenger cars and further increasing the already reformed light truck standards. Under this plan, the President set a goal of reducing the annual gasoline use in 2017 by up to 8.5 billion gallons. More specifically, we are seeking information related to fuel economy improvements for MY 2007-2017 passenger cars and MY 2010-2017 light trucks. The agency is seeking information in anticipation of obtaining statutory authority to reform the passenger car CAFE program and to set standards under that structure for MY 2010-2017 passenger cars. The agency is also seeking this information in anticipation of setting standards for MY 2012-2017 light trucks. This information will help the agency in assessing, in greater detail, the potential levels of future standards under a reformed structure, and the impact of those standards on gasoline consumption, manufacturers, consumers, the economy, and motor vehicle safety.
Airworthiness Directives; Pratt & Whitney PW4077D, PW4084D, PW4090, and PW4090-3 Turbofan Engines
The FAA is superseding an existing airworthiness directive (AD) for Pratt & Whitney PW4077D, PW4084D, PW4090, and PW4090-3 turbofan engines that were reassembled with previously used high pressure compressor (HPC) exit brush seal packs and new or refurbished HPC exit diffuser air seal lands. That AD currently requires replacing the HPC exit inner and outer brush seal packs with new brush seal packs, or replacing the HPC exit brush seal assembly with a new HPC exit brush seal assembly. This AD requires replacing the HPC exit inner and outer brush seal packs with new brush seal packs, using either original equipment manufactured (OEM) parts, or FAA-approved part manufacturer approval (PMA) parts. This proposed AD also applies to engines reassembled with a PMA HPC exit inner and or outer brush seal packs. This AD results from a request to include PMA HPC exit inner and outer brush seal packs and to include the engines with PMA parts already installed, in the AD. We are issuing this AD to prevent uncontained engine failure, damage to the airplane, and injury to passengers.

Guidance Concerning the Carriage of Service Animals in Air Transportation Into the United Kingdom
This notice publishes guidance concerning the carriage of service animals in air transportation from the United States (U.S.) to the United Kingdom (U.K.). These guidelines address the differences between U.K. laws regulating the transport of service animals on flights into the U.K. and U.S. law with respect to the carriage of service animals in air transportation. U.K. laws affecting the transport of service animals in air travel differ significantly from the requirements of the Air Carrier Access Act (ACAA), 49 U.S.C. 41705, and its implementing regulation in 14 CFR Part 382, resulting in uncertainty for carriers and persons with disabilities about the requirements that apply on flights into or transiting the U.K. The purpose of this guidance document is to assist U.S. and foreign carriers, as well as passengers with disabilities, in complying with both U.S. and U.K. regulations concerning the transport of service animals on flights from the U.S. to the U.K. by: (1) Explaining the procedures passengers must follow to comply with the U.K.'s Pet Travel Scheme (PETS); (2) explaining the procedures U.S. and foreign carriers must follow to obtain an approved Required Method of Operation (RMOP) from the U.K.'s Department for Environment Food and Rural Affairs (DEFRA); and (3) notifying both U.S. and foreign carriers operating flights between the U.S. and the U.K. that failure to obtain an approved RMOP from DEFRA will be considered a violation of the ACAA and may subject such carriers to enforcement action by the U.S. DOT.

Airworthiness Directives; McDonnell Douglas Model DC-10-30 and DC-10-30F (KC-10A and KDC-10) Airplanes, Model DC-10-40 and DC-10-40F Airplanes, and Model MD-10-30F Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain McDonnell Douglas Model DC-10-30 and DC-10-30F (KC-10A and KDC-10) airplanes, Model DC-10-40 and DC-10-40F airplanes, and Model MD-10-30F airplanes. This proposed AD would require installing bracket assemblies and jumper wires in the center main wheel well to improve the bonding path between the structure (wall) of the lower auxiliary fuel tank and its internal fuel pumps; measuring the electrical resistance between the fuel pump housings and the fuel tank structure; and doing corrective actions if necessary. This proposed AD results from fuel system reviews conducted by the manufacturer. We are proposing this AD to detect and correct an inadequate bond between the internal fuel pump housings and the structure of the lower auxiliary fuel tank. This condition, if not corrected, could fail to meet fault current requirements and result in a potential ignition source that, in combination with flammable fuel vapors, could cause a fuel tank explosion and consequent loss of the airplane.
Airworthiness Directives; McDonnell Douglas Model 717-200 Airplanes
The FAA proposes to supersede an existing airworthiness directive (AD) that applies to all McDonnell Douglas Model 717-200 airplanes. The existing AD currently requires revising the Airworthiness Limitations Section (ALS) of the Instructions for Continued Airworthiness to incorporate new removal limits for certain components of the flap system and to reduce the interval of inspections for fatigue cracking of certain principal structural elements (PSEs). This proposed AD would require revising the ALS of the Instructions for Continued Airworthiness to incorporate reduced initial inspection and repeat inspection intervals for certain PSEs. This proposed AD results from a revised damage tolerance analysis. We are proposing this AD to detect and correct fatigue cracking of certain PSEs, which could adversely affect the structural integrity of the airplane.
Airworthiness Directives; McDonnell Douglas Model MD-11 and MD-11F Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for all McDonnell Douglas Model MD-11 and MD-11F airplanes. This proposed AD would require installing bracket assemblies and jumper wires in the center main wheel well to improve the bonding path between the structure (wall) of the lower auxiliary fuel tank and its internal fuel pumps; measuring the electrical resistance between the fuel pump housings and the fuel tank structure; and doing corrective actions if necessary. This proposed AD results from fuel system reviews conducted by the manufacturer. We are proposing this AD to detect and correct an inadequate bond between the internal fuel pump housings and the structure of the lower auxiliary fuel tank. This condition, if not corrected, could fail to meet fault current requirements and result in a potential ignition source that, in combination with flammable fuel vapors, could cause a fuel tank explosion and consequent loss of the airplane.
Airworthiness Directives; McDonnell Douglas Model DC-10-10 and DC-10-10F Airplanes, Model DC-10-15 Airplanes, Model DC-10-30 and DC-10-30F (KC-10A and KDC-10) Airplanes, Model DC-10-40 and DC-10-40F Airplanes, Model MD-10-10F and MD-10-30F Airplanes, and Model MD-11 and MD-11F Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain transport category airplanes identified above. This proposed AD would require modifying the fuel boost pumps. This proposed AD results from a fuel boost pump found with blown thermal fuses and a fractured thrust washer. We are proposing this AD to prevent failure of the fuel boost pumps, which could lead to the potential of ignition sources inside fuel tanks. This condition, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.
Airworthiness Directives; McDonnell Douglas Model DC-8-33, -42, and -43 Airplanes; Model DC-8-50 Series Airplanes; Model DC-8F-54 and -55 Airplanes; Model DC-8-60 Series Airplanes; Model DC-8-60F Series Airplanes; Model DC-8-72 Airplanes; and Model DC-8-70F Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain McDonnell Douglas airplanes described previously. This proposed AD would require installing bonding jumpers to the airplane wing structure from the fuel system in-line electrical solenoid valves along the left and right wing front spar. This proposed AD results from fuel system reviews conducted by the manufacturer. We are proposing this AD to prevent point-of-contact arcing or filament heating damage in the fuel lines that could create a potential ignition source, which, in combination with flammable fuel vapors, could cause a fuel tank explosion and consequent loss of the airplane.
