Airworthiness Directives; SOCATA-Groupe AEROSPATIALE Models TB 20 and TB 21 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 reports of interference between the wing spar lower boom and the wheel fairing attaching screw. The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
Airworthiness Directives; Bombardier Model CL-600-2B16 (CL-604) Airplanes and Model CL-600-2B19 (Regional Jet Series 100 & 440) Airplanes
The FAA proposes to supersede an existing airworthiness directive (AD) that applies to certain Bombardier Model CL-600-2B16 (CL-604) airplanes and Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. These models may be referred to by their marketing designations as RJ100, RJ200, RJ440, CRJ100, CRJ200, CRJ440, and CL-65. The existing AD currently requires revising the Emergency Procedures section of the airplane flight manual (AFM) to advise the flightcrew of additional procedures to follow in the event of stabilizer trim runaway. The existing AD also requires revising the Abnormal Procedures section of the AFM to advise the flightcrew of procedures to follow in the event of MACH TRIM, STAB TRIM, and horizontal stabilizer trim malfunctions. The existing AD also requires revising the Normal section of the AFM to require a review of the location of certain circuit breakers and a functional check of the stabilizer trim system. The existing AD also requires installing circuit breaker identification collars and provides an optional terminating action for the requirements of the AD. This proposed AD would require doing the previously optional terminating action (installation of a new horizontal stabilizer trim control unit). This proposed AD results from a determination that the terminating action is necessary to address uncommanded horizontal stabilizer trim motion. We are proposing this AD to prevent horizontal stabilizer trim uncommanded motion, which could result in reduced controllability of the airplane.
Airworthiness Directives; EXTRA Flugzeugproduktions-und Vertriebs-GmbH Models EA-300, EA-300S, EA-300L, and EA-300/200 Airplanes
We propose to supersede Airworthiness Directive (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 (TIS) is done. Since we issued AD 2002-21-11, cracks have been found on Models EA-300L and EA-300/200 airplanes. Consequently, this proposed AD adds airplanes to the applicability and requires you to inspect and modify the upper longeron at the horizontal stabilizer attachment. This proposed AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. We are proposing this AD to detect and correct 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.
Airworthiness Directives; Airbus Model A330-200, A330-300, A340-200, and A340-300 Series Airplanes
This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A330-200, A330-300, A340-200, and A340-300 series airplanes. This AD requires repetitive inspections for discrepancies of the grease and gear teeth of the radial variable differential transducer of the nose wheel steering gearbox; or repetitive inspections for damage of the chrome on the bearing surface of the nose landing gear (NLG) main fitting barrel; as applicable. And, for airplanes with any discrepancy or damage, this AD requires an additional inspection or corrective actions. This AD also adds a terminating action. The actions specified by this AD are intended to prevent incorrect operation or jamming of the nose wheel steering, which could cause reduced controllability of the airplane on the ground. This action is intended to address the identified unsafe condition.
Airworthiness Directives; Boeing Model 747-100, 747-100B, 747-200B, 747-200C, 747-200F, 747SR, and 747SP Series Airplanes
The FAA is superseding an existing airworthiness directive (AD), which applies to certain Boeing Model 747 series airplanes. That AD currently requires repetitive inspections to detect cracks at certain stringer fastener locations; and repair, if necessary. For certain airplanes, that AD requires a modification in certain areas where reports indicate that cracking was prevalent. This modification terminates the repetitive inspections only for those areas, and is also an option for other airplanes affected by the existing AD. This new AD requires an additional inspection of areas that may have Alodine-coated rivets installed, and repair if necessary. This AD results from a report of cracking discovered in a skin lap joint that was previously inspected using the eddy current method. We are issuing this AD to prevent rapid decompression of the airplane due to disbonding and subsequent cracking of the skin panels.
Airworthiness Directives; Cessna Model 750 Airplanes
The FAA is superseding an existing airworthiness directive (AD) that applies to certain Cessna Model 750 airplanes. The existing AD currently requires repetitive inspections for clearance and chafing of an auxiliary power unit (APU) fuel tube assembly in the tail cone area of the airplane, and corrective actions if necessary. For certain airplanes, the existing AD also requires replacing the APU fuel line. This new AD adds airplanes to the applicability and allows operators to modify the APU fuel line by installing new fuel lines, fairleads, and clamping configurations, which is an optional terminating action for the repetitive inspections. This AD results from reports of chafed APU fuel tubes leaking into the tail cone area due to interference between the fuel tube assembly and elevator flight control cables, hydraulic lines, and high-temperature bleed air couplings. We are issuing this AD to detect and correct this interference, which could result in chafing, fuel leaking into an area where ignition sources are present, and possible fire in an area without fire detection or extinguishing provisions.
Removal of Class E Airspace; Cedar Springs, GA
This action will remove the Class E airspace at Cedar Springs, GA. The Georgia-Pacific Airport, Cedar Springs, GA, is permanently closed and is no longer operational. The closure necessitates the removal of Class E airspace.
Airworthiness Directives; EADS SOCATA Model TBM 700 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 an excessive lateral play caused by a nonconforming washer might lead to the deterioration of the elevator trim tab bearing fatigue resistance. The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-135 Airplanes and Model EMB-145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain EMBRAER Model EMB-135 airplanes and Model EMB-145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP airplanes. This proposed AD would require replacing the metallic tubes enclosing the vent and pilot valve wires in the left- and right-hand wing fuel tanks with non- conductive hoses. This proposed AD results from fuel system reviews conducted by the manufacturer. We are proposing this AD to prevent an ignition source inside the fuel tank that could ignite fuel vapor and cause a fuel tank explosion and loss of the airplane.
Airworthiness Directives; Bombardier Model CL-600-1A11 (CL-600), CL-600-2A12 (CL-601), CL-600-2B16 (CL-601-3A, CL-601-3R, and CL-604) Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Bombardier Model CL-600-1A11 (CL-600) airplanes, CL-600- 2A12 (CL-601) airplanes, and CL-600-2B16 (CL-601-3A, CL-601-3R, and CL- 604) airplanes. This proposed AD would require inspecting to identify the part number and serial number of the selector valves of the nose landing gear (NLG) and the nose gear door; and doing related investigative and corrective actions if necessary. This proposed AD results from reports of uncommanded partial retractions of the NLG. We are proposing this AD to prevent internal leakage of the selector valve, which, under certain conditions, could result in an uncommanded retraction of the NLG with consequent damage to the airplane and possible serious injury to ground personnel.
Airworthiness Directives; Fokker Model F.28 Mark 0070 and 0100 Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for all Fokker Model F.28 Mark 0070 and 0100 airplanes. This proposed AD would require 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 proposed AD would also require an inspection of fuel lines for chafing, 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 proposed AD results from a fuel leak found in the left MLG bay. We are proposing 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; Pratt & Whitney PW4077D, PW4084D, PW4090, and PW4090-3 Turbofan Engines
The FAA proposes to supersede 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 proposed AD would require 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) equivalent parts. This proposed AD would also apply to engines reassembled with a PMA equivalent HPC exit inner and/or outer brush seal packs. This proposed AD results from a request to include PMA equivalent HPC exit inner and outer brush seal packs and to include the engines with PMA equivalent parts already installed, in the AD. We are proposing this AD to prevent uncontained engine failure, damage to the airplane, and injury to passengers.
Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model ERJ 170 and ERJ 190 Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for all EMBRAER Model ERJ 170 and ERJ 190 airplanes. This proposed AD would require repetitive detailed inspections for blockage of the pitot drain holes of certain air data smart probes (ADSPs), removing accumulated moisture from the pneumatic passages of the ADSPs, related investigative actions, and corrective actions if necessary. This proposed AD results from reports of erroneous air speed indications caused by blockage of the pitot sensors due to freezing of accumulated moisture in the ADSP pneumatic passages. We are proposing this AD to prevent an erroneous air speed indication, which could reduce flightcrew ability to control the airplane.
Airworthiness Directives; EADS SOCATA Model TBM 700 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 cracks on a vertical stabilizer attachment fitting due to corrosion, have been found on an aircraft in service. The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
Airworthiness Directives; EADS SOCATA Model TBM 700 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 loose rivets on frames C18 BIS and C19, which could result in a reduced structural integrity of the tail area. The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
Additional Types of Child Restraint Systems That May Be Furnished and Used on Aircraft
On July 14, 2006, the Federal Aviation Administration (FAA) amended certain operating regulations to allow passengers or aircraft operators to furnish and use more types of Child Restraint Systems (CRS) on aircraft. The rule allowed the use of CRSs that the FAA approves under the aviation standards of Technical Standard Order C- 100b, Child Restraint Systems. In addition, the rule allowed the use of CRSs approved by the FAA under its certification regulations regarding the approval of materials, parts, processes, and appliances. The intended effect of the rule was to increase the number of CRS options that are available for use on aircraft, while maintaining safe standards for certification and approval. This action is a summary and disposition of comments received on the July 14, 2006 final rule.

Notice of Intent to Request Revision From the Office of Management and Budget of a Currently Approved Information Collection Activity, Request for Comments; FAA Antidrug And Alcohol Misuse Prevention Programs
The FAA invites public comments about our intention to request the Office of Management and Budget (OMB) to approve a current information collection. The FAA uses this information for determining program compliance or non-compliance of regulated aviation employers, oversight planning, determining who must provide annual MIS testing information, and communicating with entities subject to the program regulations.
Establishment of Class E-2 Airspace; Griffiss Airfield, Rome, NY
This notice proposes to establish 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.
Special Conditions: General Electric Company GEnx Model Turbofan Engines
This action proposes special conditions for General Electric Company (GE) GEnx turbofan engine models. These engines will have a novel or unusual design feature associated with the fan blades. The Administrator has determined that the applicable part 33 airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These proposed special conditions contain the added safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the airworthiness regulations.
Airworthiness Directives; Turbomeca Turmo IV A and IV C Series Turboshaft Engines
The FAA is superseding an existing airworthiness directive (AD) for Turbomeca Turmo IV A and IV C series turboshaft engines. That AD currently requires borescope and eddy current inspections or ultrasonic inspections of centrifugal compressor intake wheel blades for cracks and evidence of corrosion pitting, and replacement with serviceable parts. This AD requires the same actions, but would require borescope inspections at more frequent intervals for certain engines. This AD results from Turbomeca's review of the engines' service experience that determined more frequent borescope inspections are required on engines not modified to the TU 191, TU 197, or TU 224 standard. We are issuing this AD to prevent centrifugal compressor intake wheel blade cracks, which can result in engine in-flight power loss, engine shutdown, or forced landing.
Airworthiness Directives; Boeing Model 757 Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 757 airplanes. This AD requires installing a control wheel damper assembly at the first officer's drum bracket assembly and aileron quadrant beneath the flight deck floor in section 41; doing a functional test and adjustment of the new installation; and doing related investigative/corrective actions if necessary. For certain airplanes, this AD also requires doing an additional adjustment test of the re-located control wheel position sensor, and an operational test of the flight data recorder and the digital flight data acquisition unit. This AD also requires installing vortex generators (vortilons) on the leading edge of the outboard main flap on certain airplanes. This AD results from several reports that flightcrews experienced unintended roll oscillations during final approach, just before landing. We are issuing this AD to prevent unintended roll oscillations near touchdown, which could result in loss of directional control of the airplane, and consequent airplane damage and/or injury to flightcrew and passengers.
Airworthiness Directives; Air Tractor, Inc. Models AT-502, AT-502A, AT-502B, AT-602, AT-802, and AT-802A Airplanes
The FAA adopts a new airworthiness directive (AD) for certain Air Tractor, Inc. (Air Tractor) Models AT-502, AT-502A, AT-502B, AT- 602, AT-802, and AT-802A airplanes. This AD requires you to repetitively visually inspect the rudder and vertical fin hinge attaching structure (vertical fin skins, spars, hinges, and brackets) for loose fasteners, cracks, and/or corrosion. This AD also requires you to replace any damaged parts found as a result of the inspection and install an external doubler at the upper rudder hinge. This AD results from two reports of in-flight rudder separation from the vertical fin at the upper attach hinge area, and other reports of airplanes with loose hinges, skin cracks, or signs of repairs to the affected area. We are issuing this AD to detect and correct loose fasteners; any cracks in the rudder or vertical fin skins, spars, hinges or brackets; and/or corrosion of the rudder and vertical fin hinge attaching structure. Hinge failure adversely affects ability to control yaw and has led to the rudder folding over in flight. This condition could allow the rudder to contact the elevator and affect ability to control pitch with consequent loss of control.
Airworthiness Directives; BAE Systems (Operations) Limited Model BAe 146 and Avro 146-RJ Airplanes
The FAA is adopting a new airworthiness directive (AD) for all BAE Systems (Operations) Limited Model BAe 146 and Avro 146-RJ airplanes. This AD requires modifying the nose landing gear. This AD results from reports of loss of the nose wheel assembly. We are issuing this AD to prevent the nose wheel nut from loosening, and consequently, the nose wheel assembly detaching from the airplane; and to prevent the nose wheel clamping loads from applying to the machined radius at the root of the stub axle, which could result in damage to the nose landing gear.
Airworthiness Directives; Airbus Model A330 Airplanes
The FAA proposes to supersede an existing airworthiness directive (AD) that applies to certain Airbus Model 330-300 series airplanes. The existing AD currently requires reinforcement of the structure of the center fuselage by installing external stiffeners (butt straps) at frame (FR) 53.3 on the fuselage skin between left-hand (LH) and right-hand (RH) stringer (STR) 13, and related investigative and corrective actions. This proposed AD would require additional reinforcement of the structure of the center fuselage by installing external stiffeners (butt straps) at frame FR53.3 on the fuselage skin between LH and RH STR13, and related investigative and other specified actions. This proposed AD also adds airplanes to the applicability. This proposed AD results from cracking found at the circumferential joint of FR53.3. We are proposing this AD to prevent fatigue cracking of the fuselage, which could result in reduced structural integrity of the fuselage.
Airworthiness Directives; Boeing Model 737 Airplanes
The FAA proposes to supersede an existing airworthiness directive (AD) that applies to all Boeing Model 737 airplanes. The existing AD currently requires installation of a new rudder control system and changes to the adjacent systems to accommodate that new rudder control system. For certain airplanes, this proposed AD would add, among other actions, repetitive tests of the force fight monitor of the main rudder power control unit (PCU), repetitive tests of the standby hydraulic actuation system, and corrective action; as applicable. For those airplanes, this proposed AD also would add, among other actions, replacement of both input control rods of the main rudder PCU and the input control rod of the standby rudder PCU with new input control rods, as applicable, which would end the repetitive tests. For certain other airplanes, this proposed AD would add installation of an enhanced rudder control system in accordance with new service information. This proposed AD results from a report of a fractured rod end on an input control rod of the main rudder PCU. We are proposing this AD to prevent failure of one of the two input control rods of main rudder PCU, which, under certain conditions, could result in reduced controllability of the airplane; and to prevent failure of any combination of two input control rods of the main rudder PCU and/or standby rudder PCU, which could result in loss of control of the airplane. We are also proposing this AD to prevent an uncommanded rudder hardover event and consequent loss of control of the airplane due to inherent failure modes, including single-jam modes, and certain latent failures or jams combined with a second failure or jam.
Filtered Flight Data
The FAA proposes to amend the digital flight data recorder (DFDR) regulations by prohibiting the filtering of some original parameter sensor signals. This proposed rule is based on recommendations issued by the National Transportation Safety Board, and is intended to improve the accuracy and quality of the data recorded on DFDRs and used during accident and incident investigations.
Notice of Intent To Prepare an Environmental Impact Statement (EIS)
The Federal Aviation Administration (FAA), in cooperation with the National Park Service (NPS), began development of an Air Tour Management Plan (ATMP) and associated Environmental Assessment (EA) for Haleakala National Park in February 2003. The ATMP is being established pursuant to the National Parks Air Tour Management Act of 2000 (Pub. L. 106-181) and its implementing regulations contained in Title 14, Code of Federal Regulations, Part 136, National Parks Air Tour Management. The objective of the ATMP is to develop acceptable and effective measures to mitigate or prevent the significant adverse impacts, if any, of commercial air tour operations upon the natural resources, cultural resources, and visitor experiences of Haleakala National Park. The FAA and NPS have now decided to proceed with development of an Environmental Impact Statement (EIS) for this project. This decision is based on information received through the EA scoping process, the environmental analysis completed by the Agencies to date, the consideration of preliminary ATMP alternatives, and through consultations conducted pursuant to Section 106 of the National Historic Preservation Act. By this notice, the FAA and NPS are initiating a 60-day scoping period for this EIS. This timeframe is provided due to the major holidays occurring during this public review period. The FAA and NPS are now inviting the public, agencies, and other interested parties to provide written comments, suggestions, and input regarding the scope of issues and the identification of significant issues to be addressed in the EIS. Comments previously submitted in response to the EA scoping will not need to be re-submitted, as they will be considered as part of the EIS process and record. No additional scoping meetings are scheduled.
Standard Instrument Approach Procedures; Miscellaneous Amendments
This amendment amends Standard Instrument Approach Procedures (SIAPs) for operations at certain airports. These regulatory actions are needed 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.
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.
Revocation of Class D Airspace; Elko, NV
This action corrects the Document Management System docket number contained in the Direct Final Rule that was published in the Federal Register on Tuesday, July 18, 2006 (71 FR 40651). Airspace Docket No. 06-AWP-11.
Airworthiness Directives; Rolls-Royce, plc RB211 Trent 768-60, 772-60, and 772B-60 Turbofan Engines
The FAA is adopting a new airworthiness directive (AD) for Rolls-Royce, plc (RR) RB211 Trent 768-60, 772-60, and 772B-60 turbofan engines. This AD requires initial and repetitive on-wing or in-shop inspections of the high pressure (HP)/intermediate pressure (IP) turbine bearing oil feed tube heat shield. This AD results from a report that a damaged outer heat shield caused fretting of the oil feed tubes. We are issuing this AD to prevent an uncontained failure of the HP turbine disc and damage to the airplane.
Airworthiness Directives; BAE Systems (Operations) Limited Model BAe 146 Airplanes
The FAA is adopting a new airworthiness directive (AD) for all BAE Systems (Operations) Limited Model BAe 146 airplanes. This AD requires inspecting the three-phase circuit breakers and three-phase circuit breaker panels for discrepancies; and fixing any discrepancy and replacing unserviceable units with new units, if necessary. This AD results from reports of three-phase circuit breakers overheating on in- service airplanes. We are issuing this AD to prevent failure of a three-phase circuit breaker. Such failure could prevent an electrical load from being isolated from its electrical supply, which could result in smoke or fire in the flight deck.
Airworthiness Directives; BAE Systems (Operations) Limited Model BAe 146 and Avro 146-RJ Airplanes
The FAA is adopting a new airworthiness directive (AD) for all BAE Systems (Operations) Limited Model BAe 146 and Avro 146-RJ airplanes equipped with certain hydraulic accumulators. This AD requires inspecting the hydraulic accumulators to identify certain serial numbers, and replacing any affected accumulator with a new or serviceable accumulator. Operators may delay doing the replacement by doing repetitive inspections of the affected hydraulic accumulators for signs of failure (leaking or cracking), and replacing any failed accumulator with a new or serviceable unit. This AD results from a report that one hydraulic accumulator failed in service, which caused the loss of the yellow hydraulic system when the airplane was configured for landing. We are issuing this AD to prevent damage to the pressure skin, failure of certain hydraulic systems, contamination of the cabin with hydraulic mist, increased workload for the flightcrew associated with the loss of one or more hydraulic circuits, and consequent reduced controllability of the airplane.
Petitions for Exemption; Summary of Petitions Received
In accordance with 14 CFR 11.47(c), the FAA has received a petition from the Association of Flight Attendants-CWA, AFL-CIO (AFA- CWA). That petition requested an extension of the comment period for Alaska Airlines, Inc. petition for exemption. That exemption, if granted, would allow Alaska Airlines to eliminate the requirement for a procedure on their B737-400 combination passenger/cargo operations for a flight attendant to enter the pilot compartment in the event a flight crew member becomes incapacitated. The FAA finds that AFA-CWA has a substantive interest in the exemption request and has shown that good cause exists to extend the comment period if consistent with public interest.

The property will be exchanged for Parcel `1' for the purpose of relocating and constructing Perimeter Road improvements, extending and constructing NW. 42nd Court and the necessary bridge to access the Terminal and to construct a new replacement bus maintenance facility. Parcel `2' will be used by the Florida Department of Transportation/Miami-Dade Expressway Authority for a dry storm water retention area required for other roadway improvement projects in the area. The parcels are equal in size and highest/best use, therefore the exchange is considered to be an even exchange with no cash consideration to be paid by either party. This type of exchange complies with Chapter 125.37 of the Florida Statutes and will be published in newspapers of general circulation. Documents reflecting the Sponsor's request are available, by appointment only, for inspection at the Miami-Dade Aviation Department Office and the FAA Airports District Office.
Special Conditions: Boeing Model 737 Series Airplanes; Seats With Non-Traditional, Large, Non-Metallic Panels
This action proposes special conditions for Boeing Model 737 series airplanes. These airplanes will have a novel or unusual design feature(s) associated with seats that include non-traditional, large, non-metallic panels that would affect survivability during a post-crash fire event. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These proposed special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
Airworthiness Directives; Dowty Propellers R321/4-82-F/8; R324/4-82-F/9; R333/4-82-F/12; and R334/4-82-F/13 Propellers
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; B-N Group Ltd. BN-2, BN-2A, BN-2B, BN-2T, and BN-2T-4R Series (All Individual Models Included in Type Certificate Data Sheet (TCDS) A17EU, Revision 16, Dated December 9, 2002) Airplanes
The FAA adopts a new airworthiness directive (AD) for all B-N Group Ltd. BN-2, BN-2A, BN-2B, BN-2T, and BN-2T-4R series (all individual models included in Type Certificate Data Sheet (TCDS) A17EU, Revision 16, dated December 9, 2002) airplanes. This AD requires you to inspect the horizontal stabilizer attachment bolts and anchor nuts for damage and wear and replace damaged and/or worn parts with new, modified parts. If no damaged or worn parts are found during the inspection, this AD requires you to replace the horizontal stabilizer attachment bolts and anchor nuts at a specified time with new, modified parts. This AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for the United Kingdom. We are issuing this AD to detect and correct damaged and/or worn horizontal stabilizer attachment bolts and anchor nuts, which could result in failure of the horizontal stabilizer. This failure could result in loss of control.
Airworthiness Directives; Air Tractor, Inc. Model AT-602 Airplanes
The FAA adopts a new airworthiness directive (AD) for all Air Tractor, Inc. (Air Tractor) Model AT-602 airplanes. This AD requires you to repetitively inspect (using the eddy current method) the wing center splice joint two outboard fastener holes on both of the wing main spar lower caps for fatigue cracking; repair or replace any wing main spar lower cap where fatigue cracking is found; and report any fatigue cracking found. This AD results from fatigue cracking at the wing center splice joint outboard fastener hole in one of the wing main spar lower caps. We are issuing this AD to detect and correct cracks in the wing main spar lower cap, which could result in failure of the spar cap and lead to wing separation and loss of control of the airplane.
