Airworthiness Directives; Gulfstream Aerospace LP Model Gulfstream 100 Airplanes, and Model Astra SPX and 1125 Westwind Astra 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 unsafe condition is incomplete closure of the main entry door, which may result in the door opening in flight, causing damage to wing, fuselage, engine, and/or tail, and possible damage to the airplane. This AD requires actions that are intended to address the unsafe condition described in the MCAI.
Airworthiness Directives; Boeing Model 737-100, -200, -200C, -300, -400, and -500 Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This AD requires repetitive inspections to detect cracks in the vertical beam webs of the body station (BS) 178 bulkhead, and corrective actions if necessary. This AD also requires a terminating modification for the repetitive inspections. This AD results from reports of numerous cracks in the vertical beam webs. We are issuing this AD to prevent fatigue cracks in certain vertical beam webs, which could result in loss of structural integrity of the BS 178 bulkhead, and consequently could impair the operation of the control cables for the elevators, speed brakes, and landing gear, or could cause the loss of cabin pressure.
Airworthiness Directives; Airbus Model A330-200, A330-300, A340-200, A340-300, A340-500, and A340-600 Series 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 cracking of the wing MLG (main landing gear) rib 6 aft bearing forward lugs, which could result in reduced structural integrity of the MLG attachment. This AD requires actions that are intended to address the unsafe condition described in the MCAI.

Airworthiness Directives; Bombardier Model DHC-8-400 Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Bombardier Model DHC-8-400 series airplanes. This AD requires revising the Airworthiness Limitations Items (ALI) of the maintenance requirements manual to require additional inspection requirements of the maintenance requirements manual for certain principal structural elements (PSEs) related to fuselage cutouts and to reduce an inspection threshold for an existing ALI task on the aft entry door. This AD results from data obtained from the manufacturer's fatigue testing. We are issuing this AD to detect and correct fatigue cracking of certain PSEs, which could result in reduced structural integrity of the airplane.
Airworthiness Directives; Airbus Model A310-300 Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A310-300 airplanes. This AD requires replacing the existing non-return valve (NRV) of the auxiliary center tanks (ACTs) of the fuel system with a new, improved NRV. This AD results from a report that it was not possible to transfer fuel from ACTs 1 and 2 during flight, and no electronic centralized aircraft monitor warnings were triggered. Investigation revealed a faulty static inverter and blown fuse, resulting in failure of certain fueling bus bars and subsequent failure of the automatic ACT fuel transfer. We are issuing this AD to prevent these failures, combined with failure of the NRV to close. If the NRV is open during flight, the fuel supply to the engines may be reduced during cross-feed operation to the extent that fuel starvation could occur and result in engine flameout.
Airworthiness Directives; Dassault Model Mystere-Falcon 50 and 900, and Falcon 900EX Airplanes; and Model Falcon 2000 and Falcon 2000EX Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Dassault Model Mystere-Falcon 50 and 900, and Falcon 900EX airplanes; and Model Falcon 2000 and Falcon 2000EX airplanes. This AD requires an inspection of the identification plates of the outboard slats to determine the type of identification plates and the part numbers. For certain airplanes, this AD also requires a revision to the Limitations and Normal Procedures sections of the airplane flight manual to provide procedures for operation in icing conditions; and replacement of the anti-icing manifold with an anti-icing manifold of the correct type design if necessary. For certain airplanes, this AD also requires related investigative and corrective actions if necessary. This AD results from a finding that the outboard slats for Model Mystere-Falcon 50 airplanes have been erroneously authorized, in limited cases, as interchangeable for use on Model Mystere-Falcon 900 and Falcon 900EX airplanes; and Model Falcon 2000 and Falcon 2000EX airplanes. We are issuing this AD to prevent failure of the anti-icing manifold of the outboard slats, which could result in loss of control of the airplane.
Inspection Authorization 2-Year Renewal
The Federal Aviation Administration (FAA) is amending the regulations for the Inspection Authorization (IA) renewal period. The current IA regulation has a 1-year renewal period. This rulemaking changes the renewal period to once every two years. By changing the renewal period, the FAA reduces the renewal administrative costs by 50%. Both the FAA and the mechanic holding the IA will realize this cost reduction. Aviation safety will not be affected because this rulemaking does not change the requirements of the prior rule for annual activity (work performed, training, or oral examination).
Establishment of Class E Airspace; Ridgway, PA
This action establishes Class E airspace at Ridgway Landing Zone, Ridgway, PA. Development of an Area Navigation (RNAV), Helicopter Point in Space Approach, for the Ridgway Landing Zone, Ridgway, PA, has made this action necessary. Controlled airspace extending upward from 700 feet Above Ground Level (AGL) is needed to contain aircraft executing the approach to the Ridgway Landing Zone. This is a correction to a final rule published on October 17, 2006. 71 FR 60817. This final rule corrects the spelling of ``Ridgeway'' to ``Ridgway''
Airworthiness Directives; Boeing Model 777-200, -300, and -300ER Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 777-200, -300, and -300ER series airplanes. This proposed AD would require installing Teflon sleeving under the clamps of the wire bundles routed along the fuel tank boundary structure, and cap sealing certain penetrating fasteners of the main and center fuel tanks. This proposed AD results from fuel system reviews conducted by the manufacturer. We are proposing this AD to prevent electrical arcing on the fuel tank boundary structure or inside the fuel tanks, which could result in a fire or explosion.
Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG Tay 611-8, Tay 620-15, Tay 650-15, and Tay 651-54 Series Turbofan Engines
The FAA is adopting a new airworthiness directive (AD) for Rolls-Royce Deutschland Ltd & Co KG (RRD) Tay 611-8, Tay 620-15, Tay 650-15, and Tay 651-54 series turbofan engines, with certain low pressure (LP) compressor modules installed. This AD requires an ultrasonic inspection (UI) of LP compressor fan blades for cracks, within 30 days after the effective date of the AD on certain serial number (SN) Tay 650-15 engines. This AD also requires initial and repetitive UIs of LP compressor fan blades on all engines. This AD also requires, for Tay 650-15 and Tay 651-54 engines, UIs of LP compressor fan blades whenever the blade set is removed from one engine and installed on a different engine. This AD results from a report that a set of LP compressor fan blades failed before reaching the LP compressor fan blade full published life limit. We are issuing this AD to prevent LP compressor fan blades from failing due to blade root cracks, leading to uncontained engine failure and damage to the airplane.
Airworthiness Directives; Boeing Model 747 Airplanes
The FAA is adopting a new airworthiness directive (AD) for all Boeing Model 747 airplanes. This AD requires repetitive inspections for cracking of the web of the station (STA) 2360 aft pressure bulkhead around the fastener heads in the critical fastener rows in the web lap joints, from the Y-chord to the inner ring; and repair if necessary. This AD also requires a modification, which terminates the repetitive inspections. This AD results from analysis by the manufacturer that the radial lap splices of the STA 2360 aft pressure bulkhead are subject to widespread fatigue damage. We are issuing this AD to detect and correct cracking of the bulkhead web at multiple sites along the radial lap splice, which could join together to form cracks of critical length, and result in rapid decompression and loss of control of the airplane.
Airworthiness Directives; Boeing Model 767-200 and -300 Series Airplanes
The FAA is superseding an existing airworthiness directive (AD) that applies to certain Boeing Model 767-200, -300, and -300F series airplanes. That AD currently requires an inspection of visually accessible areas for indications of overheating of the heater tape attached to the potable water fill and drain lines in the forward and aft cargo compartments, exposed foam insulation or missing or damaged protective tape around the potable water fill and drain lines, and debris or contaminants on or near the potable water fill and drain lines. That AD also requires corrective action, as necessary. This new AD requires repetitive inspections of the forward and aft cargo compartments, as applicable, for discrepancies of the potable water supply and gray water drain lines; and applicable corrective actions if necessary. This AD also requires replacing the heater tapes on the potable water supply and gray water drain lines of the forward and aft cargo compartments, as applicable, with new ribbon heaters, or deactivating and removing any defective heater tape and wrapping the drain line with foam insulation; either action ends the repetitive inspections. This AD results from a report of a fire in the aft cargo compartment. We are issuing this AD to prevent overheating of the heater tape on potable water fill and drain lines, which may ignite accumulated debris or contaminants on or near the potable water fill and drain lines, resulting in a fire in the airplane.
Airworthiness Directives; Boeing Model 757 Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 757 airplanes. This AD requires inspecting certain power feeder wire bundles for damage, inspecting the support clamps for these wire bundles to determine whether the clamps are properly installed, and performing corrective actions if necessary. This AD results from a report that a power feeder wire bundle chafed against the number six auxiliary slat track, causing electrical wires in the bundle to arc, which damaged both the auxiliary slat track and power feeder wires. We are issuing this AD to prevent arcing that could be a possible ignition source for leaked flammable fluids, which could result in a fire. Arcing could also result in a loss of power from the generator connected to the power feeder wire bundle, and consequent loss of systems, which could reduce controllability of the airplane.
Airworthiness Directives; Bombardier Model DHC-8-100, -200, and -300 Series Airplanes
The FAA is superseding an existing airworthiness directive (AD), which applies to certain Bombardier Model DHC-8-100, -200, and - 300 series airplanes. That AD currently requires modification of the flight compartment door; repetitive inspections for wear of the flight compartment door hinges following modification; and repair or replacement of the hinges with new hinges if necessary. This new AD requires using revised procedures for modifying and inspecting the flight compartment door and reduces the applicability of the existing AD. This AD results from a determination that certain cockpit doors are no longer subject to the existing requirements. We are issuing this AD to prevent failure of the alternate release mechanism of the flight compartment door, which could delay or impede the evacuation of the flightcrew during an emergency. This failure also could result in the flightcrew not being able to assist passengers in the event of an emergency.
Airworthiness Directives; Airbus Model A300 B4-605R Airplanes and Model A310-308, -324, and -325 Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A300 B4-605R airplanes and Model A310-308, -324, and -325 airplanes. This AD requires modifying the Bruce floor plan electrical emergency path marking system (FPEEPMS) and, for certain airplanes, modifying the automatic switching of the emergency lighting system. This AD results from a report that in the case of vertical separation of the fuselage forward of door 1, the FPEEPMS and the exit signs do not turn on. We are issuing this AD to prevent inadequate lighting and marking of the escape path, which could delay or impede the flightcrew and passengers when exiting the airplane during an emergency landing.
Consumer Information Regarding On-Demand Air Taxi Operations
The Department of Transportation (Department) is seeking input from interested parties on the recommendation of the National Transportation Safety Board (Safety Board or NTSB) that customers of on-demand air taxi services be advised, at the time they contract for a flight, of: (1) The name of the company with operational control of the flight; (2) any ``doing business as'' names contained in such company's Operations Specifications; (3) the name of the aircraft owner; and (4) the name of any broker involved in arranging the flight. The NTSB has also recommended that customers be updated thereafter in the event such information changes. The Department will evaluate the comments to determine what, if any, changes to its economic rules applicable to on- demand air taxi operators should be made.
Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model ERJ 170 Airplanes
The FAA is revising an earlier NPRM for an airworthiness directive (AD) that applies to certain EMBRAER Model ERJ 170 airplanes. The original NPRM would have required replacing the mini-latches on certain lavatory waste compartment doors with new, stronger latches, and other specified actions. The original NPRM resulted from reports of certain lavatory waste compartment doors opening during flight due to movement of the waste compartment during takeoff, because the mini- latches installed on the doors of those compartments lose their strength over time. This action revises the original NPRM by adding airplanes to the applicability. We are proposing this supplemental NPRM to prevent the inability of the waste compartment doors to adequately contain a fire inside the lavatory waste compartment, and consequent uncontained fire and smoke within a lavatory during flight.
Airworthiness Directives; Airbus Model A330-200, A330-300, A340-200, and A340-300 Series Airplanes
We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed 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 fatigue damage with a crack propagation through the fastener line of the wing shroud box bottom panel, resulting in panel detachment and potential injuries to persons on the ground. The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
Airworthiness Directives; Airbus Model A300 B4-601, A300 B4-603, A300 B4-605R, A300 C4-605R Variant F, A310-204, A310-304, and A310-308 Airplanes Equipped With General Electric CF6-80C2 Engines
The FAA proposes to supersede an existing airworthiness directive (AD) that applies to certain Airbus Model A300 B4-600, B4- 600R, C4-605R Variant F, and F4-600R (collectively called A300-600) series airplanes; and Model A310 series airplanes. The existing AD currently requires a one-time inspection for damage of the integrated drive generator (IDG) electrical harness and pyramid arm, and repair if necessary. This proposed AD would add new repetitive inspections, which, when initiated, would terminate the inspection required by the existing AD. This proposed AD would also require repairing damage and protecting the harness. The proposed AD would also provide for optional terminating action for the repetitive inspections. This proposed AD also removes certain airplanes from the applicability of the existing AD. This proposed AD results from a report of structural damage on the forward pyramid arm of an engine pylon due to chafing of the IDG electrical harness against the structure of the pyramid arm. We are proposing this AD to prevent electrical arcing in the engine pylon, which could result in loss of the relevant alternating current (AC) bus bar, reduced structural integrity of the engine pylon, and possible loss of control of the airplane.
Airworthiness Directives; Airbus Model A318-111 and A318-112 Airplanes and Model A319, A320, and A321 Airplanes
The FAA proposes to supersede two existing airworthiness directives (ADs). One AD applies to all Airbus Model A319 and A320 airplanes and currently requires repetitive ultrasonic inspections to detect fatigue cracking in the wing/fuselage joint cruciform fittings, and corrective actions if necessary. The other AD applies to all Airbus Model A319, A320, and A321 airplanes and currently requires a revision to the Airworthiness Limitations section (ALS) of the Instructions for Continued Airworthiness (ICA). This proposed AD would require new revisions to the ALS of the ICA to incorporate service life limits for certain items and inspections to detect fatigue cracking, accidental damage, or corrosion in certain structures; and accomplishment of the repetitive ultrasonic inspections of the wing/fuselage joint cruciform fittings in accordance with the revised ALS of the ICA. This proposed AD would also add airplanes to the applicability. This proposed AD results from issuance of new and more restrictive service life limits and structural inspections based on fatigue testing and in-service findings. We are proposing this AD to detect and correct fatigue cracking, accidental damage, or corrosion in principal structural elements and to prevent failure of certain life limited parts, which could result in reduced structural integrity of the airplane.
Airworthiness Directives; Airbus Model A330 Airplanes and Model A340-200 and -300 Series Airplanes
We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed 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 un-damped extension of the main landing gear (MLG), potentially leading to loss of side stay integrity and then MLG collapse. The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
Airworthiness Directives; Bombardier Model DHC-8-400 Series Airplanes
The FAA proposes to supersede an existing airworthiness directive (AD) that applies to certain Bombardier Model DHC-8-400 series airplanes. The existing AD currently requires inspecting the electrical connectors of the fire bottles for the forward and aft baggage compartments and for the auxiliary power unit (APU) and engine nacelles to determine if they are connected correctly; and doing related investigative and corrective actions, if necessary. This proposed AD would add a requirement to install/modify lanyards, mounts, and clamps to the forward and aft baggage compartment, APU, and engine nacelle fire extinguishing systems. This proposed AD would also require installation and removal procedures for certain fire bottles and fire extinguisher cartridges. This proposed AD also adds two airplanes to the applicability. This proposed AD results from reports of the electrical connectors for the fire bottles in the forward and aft baggage compartments, APU, and engine nacelle being cross-connected. We are proposing this AD to detect and correct cross- connection of the fire bottles and to prevent cross-connection, which could result in failure of the fire bottles to discharge and consequent inability to extinguish a fire in the affected areas.
Airworthiness Directives; Turbomeca Arriel 1 Series Turboshaft Engines
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:
Airworthiness Directives; Boeing Model 777-200, -300, and -300ER Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 777-200, -300, and -300ER series airplanes. This AD requires replacement of the gimbal plates of the left and right outboard trailing edge flaps with improved gimbal plates and other specified actions. This AD results from a broken pivot link found on the inboard support for the outboard trailing edge flap. We are issuing this AD to prevent disconnection of the drive arm from its drive gimbal, due to a broken pivot link on an outboard flap support, which could result in unexpected roll of the airplane and loss of control of the airplane.
Airworthiness Directives; Airbus Model A310 Airplanes
The FAA is adopting a new airworthiness directive (AD) for all Airbus Model A310 airplanes. This AD requires doing repetitive inspections for any missing, damaged, or incorrectly installed wiper rings in the splined couplings of the flap transmission shafts; inspections for any missing, damaged, or incorrectly installed rubber gaiters and straps on the sliding bearing/plunging joints of the flap transmission; and corrective action if necessary. This AD results from reviews in which the manufacturer determined that the splined couplings and sliding bearings of the flap transmission system could be affected by corrosion and wear. We are issuing this AD to detect and correct damaged, missing, or incorrectly installed components of the flap transmission system, which could result in reduced functional integrity of the flap transmission system and consequent reduced control of the airplane.
Airworthiness Directives; Airbus Model A300 Airplanes; and Model A300 B4-600, B4-600R, and F4-600R Series Airplanes, and Model C4-605R Variant F Airplanes (Collectively Called A300-600 Series Airplanes)
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A300 airplanes; and Model A300 B4-600, B4-600R, and F4-600R series airplanes, and Model C4-605R Variant F airplanes (collectively called A300-600 series airplanes). This AD requires replacing the pressure limiter of the parking brake system with a new or modified pressure limiter. This AD results from a report indicating that failure of the parking brake system occurred on a Model A300-600 airplane. We are issuing this AD to prevent failure of the parking brake system and interference with emergency use of the brake pedals, which could lead to airplane collision with surrounding objects or departure from the runway.
Airworthiness Directives; Fokker Model F27 Mark 050 and F.28 Mark 0070 and 0100 Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Fokker Model F27 Mark 050 and F.28 Mark 0070 and 0100 airplanes. This AD requires repetitively removing the two existing escape rope assemblies in the flight compartment and installing new escape rope assemblies. This AD results from reports of findings of small cracks in the polyester assembly block in which the cotton escape rope is stored. A test revealed that the escape ropes had deteriorated over time, and the load capability was considerably reduced. We are issuing this AD to ensure that flightcrew members safely reach the ground after exiting the flight compartment window during an emergency evacuation.
Airworthiness Directives; Boeing Model 747 Airplanes
The FAA is superseding an existing airworthiness directive (AD), which applies to all Boeing Model 747 airplanes. That AD currently requires a one-time inspection to determine whether the outer cylinder of the wing landing gear has certain part numbers, and replacement of the outer cylinder of the wing landing gear with a new, improved, or reworked part if necessary. That AD also requires removal of the load evening system, if such a system is installed. This new AD requires, for certain airplanes, an additional one-time inspection to determine whether the outer cylinder has a certain other part number. For those certain airplanes, this new AD also requires replacement of the outer cylinder with a reworked or new, improved part and related investigative and corrective actions, if necessary. This AD results from identification of an additional unsafe part. We are issuing this AD to prevent fracture of the outer cylinder of the wing landing gear, which could result in collapse of the wing landing gear.
Cancellation of the Preparation of an Air Tour Management Plan and Environmental Assessment for Kalaupapa National Historical Park, Molokai, HI
The Federal Aviation Administration (FAA) announces that it will no longer prepare an Air Tour Management Plan (ATMP) and Environmental Assessment (EA) for commercial air tour operations over Kalaupapa National Historical Park (NHP), at Molokai, Hawaii. The FAA has stopped work on preparation of the ATMP and EA based upon no further operating authority interest by commercial air tour operators who had been granted Interim Operating Authority to conduct commercial air tour operations over the park unit and there are no new entrant requests to conduct commercial air tour operations.
Notice of Intent To Prepare an Environmental Impact Statement and Hold Scoping Meetings for Palm Beach International Airport (PBI), West Palm Beach, FL
The Federal Aviation Administration (FAA) is issuing this notice to advise the public it will prepare an Environmental Impact Statement (EIS) to address development of proposed airfield improvements at Palm Beach International Airport (PBI), West Palm Beach, Florida. To ensure the FAA identifies all significant issues related to the proposed action, the FAA will hold one (1) public scoping meeting and one (1) governmental and public agency scoping meeting.
Airworthiness Directives; Bombardier Model DHC-8-400 Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Bombardier Model DHC-8-400 series airplanes. This AD requires inspecting for fouling and chafing damage of the outboard brake control cable of the main landing gear, replacing the control cable if necessary, reworking the control cable cover, and, if applicable, manufacturing/installing an offset plate on the control cable cover. This AD results from a review of brake control cable operation conducted by the manufacturer. We are issuing this AD to prevent abrasion and wear of the outboard brake control cable, which could lead to cable separation and reduced control of airplane braking.
Airworthiness Directives; Boeing Model 747-100B SUD, 747-200B, 747-300, 747-400, 747-400D, and 747SP Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 747-100B SUD, 747-200B, 747-300, 747-400, 747- 400D, and 747SP series airplanes. This AD requires repetitive inspections for cracking of the crease beam and adjacent intercostals, stringers, frames, and skin panels; and related investigative and corrective actions if cracking is found. This AD results from a report indicating that an operator discovered crease beam cracking on two Model 747 airplanes. We are issuing this AD to detect and correct cracking of the crease beam and adjacent structure, which could become large and result in in-flight depressurization and inability of the airframe structure to sustain flight loads.
Airworthiness Directives; Bombardier Model DHC-8-400 Series Airplanes
The FAA is superseding an existing airworthiness directive (AD), which applies to certain Bombardier Model DHC-8-400 series airplanes. That AD currently requires revising the airplane flight manual (AFM) to advise the flightcrew of appropriate procedures to follow in the event that a main landing gear (MLG) fails to extend following a gear-down selection. That AD also currently requires repetitive replacement of the left and right MLG uplock assemblies with new assemblies; and an inspection of the left and right MLG uplock rollers for the presence of an inner low friction liner, and corrective actions if necessary. This new AD revises the requirement for replacing the left and right MLG uplock assemblies by allowing replacement with alternative parts. For a certain MLG uplock assembly, this new AD requires repetitive inspections of the uplock hatch lower jaw for the presence of a wear groove and replacement with an improved part if necessary. For a certain MLG uplock assembly, this new AD requires repetitive inspections of the uplock roller to ensure that it rotates freely and replacement with a new part if necessary. This new AD allows optional replacement of the left and right MLG uplock assemblies with improved parts, which ends the requirements of the AFM revision and repetitive replacement and inspections. This new AD removes airplanes from the applicability. This AD results from development of a terminating action. We are issuing this AD to ensure that the flightcrew has the procedures necessary to address failure of an MLG to extend following a gear-down selection; and to detect and correct such failure, which could result in a gear-up landing and possible injury to passengers and crew.
Airworthiness Directives; Saab Model SAAB-Fairchild SF340A (SAAB/SF340A) and SAAB 340B Airplanes
The FAA is superseding an existing airworthiness directive (AD), which applies to certain Saab Model SAAB-Fairchild SF340A and SAAB 340B airplanes. That AD currently requires repetitive inspections for wear of the brushes and leads and for loose rivets of the direct current (DC) starter generator, and related investigative/corrective actions if necessary. This new AD requires installing new, improved generator control units (GCUs). Installing the GCUs ends the repetitive inspection requirements of the existing AD. This AD results from reports of premature failures of the DC starter generator prior to scheduled overhaul. We are issuing this AD to prevent failure of the starter generator, which could cause a low voltage situation in flight and result in increased pilot workload and reduced redundancy of the electrical powered systems.
Airworthiness Directives; DORNIER LUFTFAHRT GmbH Model 228-212 Airplanes
The FAA is adopting a new airworthiness directive (AD) for DORNIER LUFTFAHRT GmbH Model 228-212 airplanes. This AD requires you to inspect the landing gear carbon brake assembly. This AD results from mandatory continuing airworthiness information (MCAI) issued by the European Aviation Safety Agency (EASA), which is the airworthiness authority for the European Union. We are issuing this AD to inspect the landing gear carbon brake assembly to detect and replace loose bolts or self-locking nuts, which could result in the brake assembly detaching and malfunctioning, degrade brake performance and potentially cause loss of control of the aircraft during landing and roll-out.
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 replacement of certain electrical bonding clamps and attaching hardware with new or serviceable parts, as applicable, and other specified action. This AD results from failure of an electrical bonding clamp, used to attach the electrical bonding straps to the fuel system lines. We are issuing this AD to prevent loss of bonding protection in the interior of the fuel tanks or adjacent areas that, in combination with lightning strike, could result in a fuel tank explosion and consequent loss of the airplane.
Airworthiness Directives; Boeing Model 737-600, -700, -700C, -800, and -900 Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 737-600, -700, -700C, -800, and -900 series airplanes. This AD requires testing the electrical resistance of the bond between the bulkhead fitting for the fuel feed line and the front spar of the left and right wings, inspecting an adjacent bonding jumper to make sure it is installed correctly, and performing corrective and other specified actions as applicable. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent arcing or sparking in the fuel tank in the event of a lightning strike, which could result in an uncontrolled fire or explosion.
Airworthiness Directives; Airbus Model A318, A319, A320, and A321 Airplanes
The FAA proposes to supersede an existing airworthiness directive (AD) that applies to all Airbus Model A318, A319, A320, and A321 airplanes. The existing AD currently requires inspecting to determine the part number and serial number of the fuel tank boost pumps and, for airplanes with affected pumps, revising the airplane flight manual (AFM) and the FAA-approved maintenance program. The existing AD also provides for optional terminating action for compliance with the revisions to the AFM and the maintenance program. This proposed AD would require modifying or replacing the fuel tank boost pumps, which would allow removal of the limitations from the AFM and the maintenance program. This proposed AD results from a report that a fuel tank boost pump failed in service, due to a detached screw of the boost pump housing that created a short circuit between the stator and rotor of the boost pump motor and tripped a circuit breaker. We are proposing this AD to prevent electrical arcing in the fuel tank boost pump motor, which, in the presence of a combustible air-fuel mixture in the pump, could result in an explosion and loss of the airplane.
Airworthiness Directives; Airbus Model A300 Airplanes; Model A310 Airplanes; and Model A300 B4-600, B4-600R, and F4-600R Series Airplanes, and Model C4-605R Variant F Airplanes (Collectively Called A300-600 Series Airplanes)
The FAA proposes to supersede an existing airworthiness directive (AD) that applies to all Airbus Model A300 airplanes and Model A310 airplanes, and certain Airbus Model A300-600 series airplanes. The existing AD currently requires an inspection of the wing and center fuel tanks to determine if certain P- clips are installed and corrective action if necessary; an inspection of electrical bonding points of certain equipment in the center fuel tank for the presence of a blue coat and related investigative and corrective actions if necessary; and installation of new bonding leads and electrical bonding points on certain equipment in the wing, center, and trim fuel tanks, as necessary. This proposed AD would require, for certain airplanes, installation of bonding on an additional bracket. This proposed AD results from fuel system reviews conducted by the manufacturer. We are proposing this AD to ensure continuous electrical bonding protection of equipment in the wing, center, and trim fuel tanks and to prevent damage to wiring in the wing and center fuel tanks, due to failed P-clips used for retaining the wiring and pipes, which could result in a possible fuel ignition source in the fuel tanks.
Establishment of Class D Airspace; Griffiss Airfield, Rome, NY
This action establishes Class D airspace at Griffiss Airfield, Rome, NY. This action is necessary for the protection of an activated control tower for Griffiss Airfield, Rome, NY. The area would be depicted on aeronautical charts for pilot reference. This was published in the Federal Register on November 17, 2006. 71 FR 66893.
Establishment of Class E-2 Airspace; Griffiss Airfield, Rome, NY
This notice establishes Class E-2 airspace at Griffiss Airfield, Rome, NY. The opening of a tower and for the protection of instrument approaches make this action necessary. Controlled airspace extending upward from the surface to the base of the overlying controlled airspace is needed to contain aircraft executing an approach. The area would be depicted on aeronautical charts for pilot reference. This was published in the Federal Register on November 17, 2006. 71 FR 66894.
Airworthiness Directives; Dassault Model Mystere-Falcon 900 and Falcon 900EX 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 smoke or fire, which could be fanned by oxygen leakage from the third crew member oxygen mask box. This AD requires actions that are intended to address the unsafe condition described in the MCAI.

Standard Instrument Approach Procedures, Weather Takeoff Minimums; Miscellaneous Amendments
This amendment establishes, amends, suspends, or revokes Standard Instrument Approach Procedures (SIAPs) and/or Weather Takeoff Minimums 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, addition of new obstacles, or changes in 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; EXTRA Flugzeugproduktions-und Vertriebs-GmbH Models EA-300, EA-300S, EA-300L, and EA-300/200 Airplanes
We are adopting a new airworthiness directive (AD) to supersede AD 2002-21-11, which applies to certain EXTRA Flugzeugbau GmbH (EXTRA) Model EA-300S airplanes. AD 2002-21-11 currently requires you to inspect, using a fluorescent dye check penetrant method, the upper longeron at the horizontal stabilizer attachment for cracks, repair any cracks found, and modify the horizontal stabilizer. That AD also requires a limit on operation to the Normal category until the initial inspection and modification on airplanes with less than 200 hours time-in-service is done. Since we issued AD 2002-21-11, cracks have been found on Models EA-300L and EA-300/200 airplanes. Consequently, this AD adds airplanes to the Applicability section and requires you to inspect and modify the upper longeron at the horizontal stabilizer attachment. This AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. We are issuing this AD to detect, correct, and prevent cracks in the upper longeron at the horizontal stabilizer attachment, which could result in structural failure of the aft fuselage. This failure could lead to loss of control.
