Pursuant to Section 176(c) of the Clean Air Act Amendments of 1990, the FAA announces the availability of the Final General Conformity Determination for Operations of Southwest Airlines Co. (Southwest) at Denver International Airport (DEN). FAA has determined that emissions from Southwest's operations at DEN conform to the Colorado State Implementation Plan (SIP). In accordance with the requirements of 40 CFR 93.156 (b), the Draft Conformity Determination, Proposed Operations of Southwest Airlines Co. at Denver International Airport, Denver, CO was made available for public review beginning April 21, 2006. Notice of the draft determination was published in the Rocky Mountain News, Denver, Colorado on April 21, 2006, and copies of the draft determination were made available at DEN. The Notice of Draft General Conformity Determination was published in the Federal 1Register on April 27, 2006 (71 FR 24903). No comments were submitted during the public comment period, which ended on May 30, 2006. Consequently, the Final General Conformity Determination consists of the Draft General Conformity Determination, with the following typographical corrections. The corrections are needed to clarify terms describing aircraft operations and to correct the reference to the maximum foreseeable aircraft activity used to predict aircraft emissions, as documented in Table 1. 1. Page 24903, last sentence on this page under SUPPLEMENTARY INFORMATION shall be revised to read: ``At that time Southwest indicated an interest in increasing service to as many as 50 or 60 daily landing/take-off cycles (LTOs) at DEN, but agreed to maintain * * *'' 2. Page 24904, second sentence of the last paragraph under SUPPLEMENTARY INFORMATION shall be revised to read: ``This General Conformity Determination addresses FAA's proposed Federal action to amend Southwest's operation specifications (OpSpecs) to accommodate future aircraft activity as high as 60 daily LTOs at DEN * * *'' 3. Page 24904, fourth sentence of the 1st paragraph under Aircraft and Supporting Equipment Emissions shall be revised to read: ``Under the Proposed Action scenario, aircraft emissions were quantified based on this maximum foreseeable level and conservatively assumed to occur every day of the year for a total of 21,900 LTOs per year.''

Airworthiness Directives; Eurocopter France Model AS350B, AS350B1, AS350B2, AS350B3, AS350BA, AS350C, AS350D, AS350D1, and AS355E Helicopters
This document proposes adopting a new airworthiness directive (AD) for the specified Eurocopter France (Eurocopter) model helicopters. This proposal would require replacing a certain hydraulic drive belt (drive belt). Also proposed is reducing the lubrication time interval for a certain hydraulic pump drive shaft (drive shaft). This proposal is prompted by in-flight failures of the drive belt and the drive shaft. The actions specified by this proposed AD are intended to prevent in-flight failure of the drive belt or drive shaft, loss of hydraulic power to the flight control system, and subsequent loss of control of the helicopter.
Airworthiness Directives; Boeing Model 767-200 and -300 Series Airplanes
The FAA proposes to supersede an existing airworthiness directive (AD) that applies to certain Boeing Model 767-200, -300, and -300F series airplanes. The existing 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 proposed AD would require 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 proposed AD also would require 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, which would end the repetitive inspections. This proposed AD results from a report of a fire in the aft cargo compartment. We are proposing 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; Fokker Model F27 Mark 050 and Model F.28 Mark 0070 and 0100 Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Fokker Model F27 Mark 050 and Model F.28 Mark 0070 and 0100 airplanes. This proposed AD would require repetitively removing the two existing escape rope assemblies in the flight compartment and installing new escape rope assemblies. This proposed 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 proposing this AD to ensure that flightcrew members safely reach the ground after exiting the flight compartment window during an emergency evacuation.
Airworthiness Directives; Airbus Model A300 and A310 Airplanes; and Airbus 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 adopt a new airworthiness directive (AD) for all Airbus Model A300 and A310 airplanes and A300-600 series airplanes. This proposed AD would require inspecting for discrepancies of all electrical bundles located in the leading and trailing edges of the wings, and performing corrective actions if necessary. This proposed AD results from fuel system reviews conducted by the manufacturer. We are proposing this AD to prevent an ignition source, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.
Airworthiness Directives; Mitsubishi Heavy Industries MU-2B Series Airplanes
We are adopting a new airworthiness directive (AD) for all Mitsubishi Heavy Industries MU-2B series airplanes. This AD requires you to do the following: Remove and visually inspect the wing attach barrel nuts, bolts, and retainers for cracks, corrosion, and fractures; replace any cracked, corroded, or fractured parts; inspect reusable wing attach barrel nuts and bolts for deformation and irregularities in the threads; check the minimum breakaway torque of reused wing attach barrel nuts; replace any deformed or irregular parts; and install new or reusable parts and torque to the correct value. This AD results from a recent safety evaluation that used a data-driven approach to evaluate the design, operation, and maintenance of the MU-2B series airplanes in order to determine their safety and define what steps, if any, are necessary for their safe operation. Part of that evaluation was the identification of unsafe conditions that exist or could develop on the affected type design airplanes. We are issuing this AD to detect and correct cracks, corrosion, fractures, and incorrect torque values in the wing attach barrel nuts, which could result in failure of the wing barrel nuts and/or associated wing attachment hardware. This failure could lead to in-flight separation of the outer wing from the center wing section and result in loss of controlled flight.
Office of Commercial Space Transportation; Notice of Availability and Request for Comment on a Draft Environmental Assessment (EA) for the Blue Origin West Texas Commercial Launch Site
In accordance with National Environmental Policy Act (NEPA) regulations, the FAA is announcing the availability of and requesting comments on the Draft EA for the Blue Origin West Texas Commercial Space Launch Site. Under the proposed action, the FAA would issue one or more experimental permits and/or licenses to Blue Origin to launch reusable launch vehicles (RLVs) \1\ on suborbital, ballistic trajectories. In addition, Blue Origin would construct a private launch site, which would include a vehicle processing facility, launch complex, vehicle landing and recovery area, space flight participant training facility, and other minor support facilities. The EA evaluates potential impacts to the environment from the proposed activities. The FAA may use the analysis in the EA as the basis for making a determination to prepare an Environmental Impact Statement or a Finding of No Significant Impact regarding the issuance of a license and/or permit(s) to Blue Origin.
Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP Airplanes
The FAA withdraws a notice of proposed rulemaking (NPRM) that proposed a new airworthiness directive (AD) for certain EMBRAER Model EMB-145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP airplanes. The proposed AD would have required modifying the routing of wire harness W407 near the fire extinguishing tube in the area of each engine, and installing new supports for related wiring. Since the proposed AD was issued, we have received new data indicating that the identified unsafe condition does not exist. Accordingly, the proposed AD is withdrawn.
Notice of Passenger Facility Charge (PFC) Approvals and Disapprovals
The FAA publishes a monthly notice, as appropriate, of PFC approvals and disapprovals under the provisions of the Aviation Safety and Capacity Expansion Act of 1990 (Title IX of the Omnibus Budget Reconciliation Act of 1990) (Pub.

Airworthiness Directives; Goodrich Evacuation Systems Approved Under Technical Standard Order (TSO) TSO-C69b and Installed on Airbus Model A330-200 and -300 Series Airplanes, Model A340-200 and -300 Series Airplanes, and Model A340-541 and -642 Airplanes
The FAA is correcting an inadvertent error in an existing airworthiness directive (AD) that was published in the Federal Register on June 12, 2006 (71 FR 33606). The error resulted in an incorrect reference to the airplane manufacturer instead of the TSO holder. This AD applies to Goodrich evacuation systems approved under TSO-C69b and installed on certain Airbus Model A330-200 and -300 series airplanes, Model A340-200 and -300 series airplanes, and Model A340-541 and -642 airplanes. This AD requires inspecting to determine the part number of the pressure relief valves on the affected Goodrich evacuation systems, and corrective action if necessary.
Notice of a Change in Direction Finder Availability Throughout United States, Excluding Alaska
The Federal Aviation Administration (FAA) is requesting public comment on a proposal to decommission all 54 Direction Finders (DF) and the associated DF approaches in all states other than Alaska. DF's have been used sparingly over the last nine years and the equipment is beyond its useful lifecycle. Improved radar coverage, pilot education and technologies such as area navigation (RNAV) and global positioning satellite (GPS) have reduced the utilization of DF steers and have essentially made DF's obsolete. A Federal Safety Risk Management Panel (SRMP) has determined that if pilots need orientation assistance, that our existing orientation methods, VOR, ADF, and GPS are reliable and meet the needs of our aviation community. Decommissioning would coincide with the Flight Services service provider's plan to consolidate the 58 flight service stations to 20 facilities.
Proposed Modification of Class E Airspace; Pierre, SD
This document proposes to modify Class E airspace at Pierre, SD. Standard Instrument Approach Procedures to several Runways have been developed for the Pierre Regional Airport. Controlled airspace extending upward from the surface of the earth is needed to contain aircraft executing these approaches. This action modifies the existing radius of Class E airspace, for Pierre Regional Airport.
Proposed Modification of Class E Airspace; Chamberlain, SD
This document proposes to modify Class E airspace at Chamberlain, SD. Standard Instrument Approach Procedures have been developed for Chamberlain Municipal Airport, Chamberlain, SD. Controlled airspace extending upward from 700 feet or more above the surface of the earth is needed to contain aircraft executing these approaches. This action would increase the area of the existing controlled airspace for Chamberlain, SD.

Kellogg Airport, Located in Battle Creek, MI
The FAA is making available an EA and FONSI/ROD for the evaluation of environmental impacts associated with proposed construction of a new 4,100 foot General Aviation runway executed by the FAA, for the W.K. Kellogg Airport located in Battle Creek, Michigan. Point of Contact: Mr. Brad Davidson, Environmental Protection Specialist, FAA Great Lakes Region, Detroit Airports District Office, 11677 South Wayne Road, Suite 107, Romulus, MI 48174 (734) 229-2900.
Airworthiness Directives; Boeing Model 757-200 Series Airplanes Modified by Supplemental Type Certificate (STC) SA979NE
The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 757-200 series airplanes. This AD requires a one- time deactivation of the auxiliary fuel system, repetitive venting and draining of the auxiliary fuel tank sumps, and revising the Limitations section of the airplane flight manual to limit the maximum cargo weight. This AD results from a re-evaluation of the floor structure and cargo barriers conducted by the STC holder. We are issuing this AD to prevent structural overload of the auxiliary fuel tank support structure, which could cause the floor beams to fail, damaging the primary flight controls and the auxiliary power unit fuel lines that pass through the floor beams, resulting in loss of control of the airplane. We are also issuing this AD to prevent structural overload of the cargo barriers, which could cause the barriers to fail, allowing the cargo to shift, resulting in damage to the auxiliary fuel tanks, residual fuel leakage, and consequent increased risk of a fire.
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; Bombardier 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-600-2B19 (Regional Jet Series 100 & 440) airplanes. The existing AD currently requires repetitive detailed and eddy current inspections of the main fittings of the main landing gears (MLG) to detect discrepancies, and related investigative/corrective actions if necessary. The existing AD also requires servicing the shock strut of the MLGs; inspecting the shock strut of the MLGs for nitrogen pressure, visible chrome dimension, and oil leakage; and servicing any discrepant strut. This proposed AD would require installing a new, improved MLG main fitting, which would terminate the repetitive inspection and servicing requirements of the existing AD. This proposed AD results from stress analyses that showed certain main fittings of the MLGs are susceptible to premature cracking, starting in the radius of the upper lug. We are proposing this AD to detect and correct premature cracking of the main fittings of the MLGs, which could result in failure of the fittings and consequent collapse of the MLGs during landing.
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 proposes to adopt 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 proposed AD would require an ultrasonic inspection (UI) of LP compressor fan blades for cracks, within 30 days after the effective date of the proposed AD on certain serial number (SN) Tay 650-15 engines. This proposed AD would also require repetitive UIs of LP compressor fan blades on all engines. This proposed AD would also require, 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 proposed 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 proposing 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 727 Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 727 airplanes. This AD requires repetitive measurements of the freeplay of the left and right outboard aileron balance tabs and of the upper and lower rudder tabs, and related investigative/corrective actions if necessary. This AD also requires repetitive lubrication of the hinge bearings and rod end bearings of the outboard aileron balance tabs. This AD results from reports of freeplay-induced vibration of the outboard aileron balance tabs and rudder tabs. We are issuing this AD to prevent excessive vibration of the airframe during flight, which could result in divergent flutter and loss of control of the airplane.
Petitions for Exemption; Summary of Petitions Received
Pursuant to FAA's rulemaking provisions governing the application, processing, and disposition of petitions for exemption part 11 of Title 14, Code of Federal Regulations (14 CFR), this notice contains a summary of certain petitions seeking relief from specified requirements of 14 CFR.

Airworthiness Directives; Saab Model SAAB-Fairchild SF340A (SAAB/SF340A) and SAAB 340B Airplanes
This document revises an earlier proposed airworthiness directive (AD), applicable to certain Saab Model SAAB-Fairchild SF340A (SAAB/SF340A) and SAAB 340B airplanes, that would have required modification of the hot detection system of the tail pipe harness of the engine nacelles. This new action revises the original NPRM by reducing the compliance time for the modification and adding repetitive inspections. The actions specified by this new proposed AD are intended to prevent false warning indications to the flightcrew from the hot detection system due to discrepancies of the harness, which could result in unnecessary aborted takeoffs on the ground or an in-flight engine shutdown. This action is intended to address the identified unsafe condition.
Airworthiness Directives; Learjet Model 45 Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Learjet Model 45 airplanes. This proposed AD would require revising the Airworthiness Limitations section of the airplane maintenance manual to incorporate certain inspections and compliance times to detect fatigue cracking of certain principal structural elements (PSEs). This proposed AD results from new and more restrictive life limits and inspection intervals for certain PSEs. We are proposing this AD to ensure that fatigue cracking of various PSEs is detected and corrected; such fatigue cracking could adversely affect the structural integrity of these airplanes.
Modification of Class E Airspace; Keokuk Municipal Airport, IA
This action amends Title 14 Code of Federal Regulations, part 71 (14 CFR part 71) by modifying the Class E airspace area at Keokuk Municipal Airport, IA. The establishment of Area Navigation (RNAV) Global Positioning System (GPS) Instrument Approach Procedures (IAP) to Runways (RWY) 8, 14, 26 and 32 and amendments to existing Non- directional Beacon (NDB) IAPs to RWY 14 and 26 requires the modification of the Class E airspace area beginning at 700 feet above ground level (AGL). This airspace area and the legal description are modification to conform to the criteria in FAA Orders.
Proposed Establishment of Class E5 Airspace; Higginsville, MO
This notice proposes to amend part 71 of the Federal Aviation Regulations (14 CFR part 71) by establishing a Class E airspace area extending upward from 700 feet above the surface at Higginsville Industrial Municipal Airport, MO.
Modification of Class E Airspace; Scottsbluff, Western Nebraska Regional Airport/William B. Heilig Field, NE
This action amends Title 14 Code of Federal Regulations, part 71 (14 CFR part 71) by revising Class E airspace areas at Scottsbluff, Western Nebraska Regional Airport/William B. Heilig Field, NE. The establishment of a Localizer/Distance Measuring Equipment (LOC/DME) Instrument Approach Procedure (IAP) to Runway (RWY) 12 requires the modification of the Class E airspace area beginning at 700 feet above ground level (AGL). This airspace area and the legal description are modified to conform to the criteria in the FAA Orders.
Airworthiness Directives; Bell Helicopter Textron Canada Model 222, 222B, 222U, 230, and 430 Helicopters
This amendment adopts a new airworthiness directive (AD) for the specified Bell Helicopter Textron Canada (BHTC) model helicopters. This action requires initial and repetitive inspections of each tail rotor counterweight bellcrank (bellcrank) with a specified part number and serial number. If external damage, a crack, roughness, or looseness between the bearing set and bellcrank is found or if bearing set axial play exceeds 0.015 inch, this action requires replacing the bellcrank with an airworthy bellcrank with two prefix letters in the serial number. This amendment is prompted by reports of failure and subsequent loss of a weighted portion of the bellcrank and reports of certain replacement bellcranks having design flaws. The actions specified in this AD are intended to prevent bellcrank failure, loss of a weighted portion of the bellcrank, and subsequent loss of control of the helicopter.
Airworthiness Directives; Raytheon Aircraft Company 65, 90, 99, and 100 Series Airplanes
We are adopting a new airworthiness directive (AD) that supersedes AD 92-07-05, which applies to certain Raytheon Aircraft Company (Raytheon) (formerly Beech) 65, 90, 99, and 100 series airplanes. AD 92-07-05 currently requires you to inspect the rudder trim tab for proper moisture drainage provisions, and if the correct drainage provisions do not exist, before further flight, modify the rudder trim tab. This AD results from receiving and evaluating new service information that requires the actions of AD 92-07-05 for the added serial numbers LJ-1281 through LJ-1732 for the Model C90A airplanes. This AD retains all the actions of AD 92-07-05 and adds serial numbers LJ-1281 through LJ-1732 for the Model C90A airplanes in the applicability section. We are issuing this AD to prevent water accumulation in the rudder trim tab, which could result in a change in the mass properties and possibly a lower flutter speed of the airplane. A lower airplane flutter speed could result in failure and loss of control of the airplane.
Special Conditions; Cessna Aircraft Company Model 510 Airplane; Turbofan Engines and Engine Location
This notice proposes special conditions for the Cessna Aircraft Company, Model 510 airplane. This new airplane will have novel and unusual design features not typically associated with normal, utility, acrobatic, and commuter category airplanes. These design features include turbofan engines and engine location, for which the applicable regulations do not contain adequate or appropriate airworthiness standards. These proposed special conditions contain the additional airworthiness standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
RTCA Special Committee 202: Portable Electronic Devices
The FAA is issuing this notice to advise the public of a meeting of FTCA Special Committee 202: Portable Electronic Devices.
Approval of Noise Compatibility Program; Southwest Florida International Airport, Fort Myers, FL
The Federal Aviation Administration (FAA) announces its findings on the noise compatibility program submitted by the Lee County Port Authority under the provisions of 49 U.S.C. (the Aviation Safety and Noise Abatement Act, hereinafter referred to as ``the Act'') and 14 CFR part 150. These findings are made in recognition of the description of Federal and nonfederal responsibilities in Senate Report No. 96-52 (1980). On February 11, 2005, the FAA determined that the noise exposure maps submitted by the Lee County Port Authority under Part 150 were in compliance with applicable requirements. On May 30, 2006, the FAA approved the Southwest Florida International Airport Noise Compatibility Program. Most of the recommendations of the program were approved.
Airworthiness Directives; MD Helicopters, Inc., Model 600N Helicopters
The FAA withdraws a notice of proposed rulemaking (NPRM) proposing a new Airworthiness Directive (AD) for MD Helicopters, Inc. (MDHI) Model 600N helicopters. The NPRM proposed adding six more inspection holes in the aft fuselage skin panels and inspecting the upper and lower tailboom attachment fittings, the upper longerons, and the angles and nutplates for cracks. Also, the NPRM proposed a terminating action of modifying the fuselage aft section to strengthen the tailboom attachments and longerons. Since issuing the NPRM, we have received a report of an in-flight separation of the tailboom in the inspection area. Based on that accident and due to the critical unsafe condition, we issued a final rule; request for comments that addressed the actions proposed in the NPRM. Accordingly, we withdraw the proposed AD.
Airworthiness Directives; Pilatus Aircraft Ltd. Models PC-12 and PC-12/45 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 airworthiness authority of another country to identify and correct an unsafe condition on an aviation product. The proposed AD would require actions that are intended to address an unsafe condition described in the MCAI.
Airworthiness Directives; Arrow Falcon Exporters, Inc. (Previously Utah State University); Firefly Aviation Helicopter Services (Previously Erickson Air-Crane Co.); California Department of Forestry; Garlick Helicopters, Inc.; Global Helicopter Technology, Inc.; Hagglund Helicopters, LLC (Previously Western International Aviation, Inc.); International Helicopters, Inc.; Precision Helicopters, LLC; Robinson Air Crane, Inc.; San Joaquin Helicopters (Previously Hawkins and Powers Aviation, Inc.); S.M.&T. Aircraft (Previously US Helicopters, Inc., UNC Helicopter, Inc., Southern Aero Corporation, and Wilco Aviation); Smith Helicopters; Southern Helicopter, Inc.; Southwest Florida Aviation International, Inc. (Previously Jamie R. Hill and Southwest Florida Aviation); Tamarack Helicopters, Inc. (Previously Ranger Helicopter Services, Inc.); US Helicopter, Inc. (Previously UNC Helicopter, Inc.); West Coast Fabrication; and Williams Helicopter Corporation (Previously Scott Paper Co.) Model HH-1K, TH-1F, TH-1L, UH-1A,
This document proposes adopting a new airworthiness directive (AD) for the specified restricted category type-certificated helicopters. The AD would require a review of the helicopter records to determine the Commercial and Government Entity (CAGE) code of the tail rotor (T/R) slider. If the T/R slider is FAA approved or has a certain legible CAGE code, this AD would require no further action. If you cannot determine whether the T/R slider is FAA approved and it has no stamped CAGE code, an illegible stamped CAGE code, or an affected CAGE code, the AD would also require, before further flight and at specified intervals, magnaflux inspecting the T/R slider for a crack. If a crack is found, the AD would require, before further flight, replacing the T/ R slider with an airworthy T/R slider. The AD would also require replacing the T/R slider with an airworthy T/R slider on or before accumulating 1,000 hours time-in-service (TIS) or on or before 12 months, whichever occurs first. This proposal is prompted by two accidents attributed to sub-standard T/R sliders that failed during flight. The actions specified by the proposed AD are intended to prevent failure of a T/R slider, loss of T/R control, and subsequent loss of control of the helicopter.
Airworthiness Directives; Bell Helicopter Textron Canada Model 206L Series Helicopters
This document proposes adopting a new airworthiness directive (AD) for the Bell Helicopter Textron Canada (BHTC) Model 206L series helicopters. This proposal would require inspecting the fuel low-level detector switch unit (switch unit) to determine if it is a certain serial-numbered switch unit that may fail to indicate a low fuel condition. If the serial number is missing or unreadable, the mounting flange of the switch unit is not colored red or the purchase date is within a certain range or cannot be determined, this proposal would require an operational test. The AD would also require replacing before further flight each affected switch unit with an airworthy switch unit that is not listed in the applicability of the AD. This proposal is prompted by the manufacturer's discovery that eight switch units may have a manufacturing flaw that could cause them to hang in the high position and fail to indicate a low fuel condition. The actions specified by this proposed AD are intended to prevent failure of the switch unit to indicate a low fuel condition that could lead to fuel exhaustion and a subsequent forced landing.
Airworthiness Directives; Pilatus Aircraft Ltd. Models PC-6, PC-6-H1, PC-6-H2, PC-6/350, PC-6/350-H1, PC-6/350-H2, PC-6/A, PC-6/A-H1, PC-6/A-H2, PC-6/B-H2, PC-6/B1-H2, PC-6/B2-H2, PC-6/B2-H4, PC-6/C-H2, and PC-6/C1-H2 Airplanes
We are adopting a new airworthiness directive (AD) that supersedes AD 2002-21-08, which applies to certain Pilatus Aircraft Ltd (Pilatus) Model PC-6 airplanes. AD 2002-21-08 currently requires you to inspect the aileron assembly for correct configuration and modify as necessary. Since we issued AD 2002-21-08, the FAA determined the action should also apply to all the models of the PC-6 airplanes listed in the type certificate data sheet of Type Certificate (TC) No. 7A15 that were produced in the United States through a licensing agreement between Pilatus and Fairchild Republic Company (also identified as Fairchild Industries, Fairchild Heli Porter, or Fairchild-Hiller Corporation). In addition, the intent of the applicability of AD 2002-21-08 was to apply to all the affected serial numbers of the airplane models listed in TC No. 7A15. This AD retains all the actions of AD 2002-21-08, adds those Fairchild Republic Company airplanes to the applicability of this AD, and lists the individual specific airplane models. We are issuing this AD to correct improper aileron assembly configuration, which could result in failure of the aileron mass balance weight. Such failure could lead to loss of control of the airplane.
Airworthiness Directives; Boeing Model 737 Airplanes
The FAA is adopting a new airworthiness directive (AD) for all Boeing Model 737 airplanes. This AD requires revising the airplane flight manual to advise the flightcrew of improved procedures for pre- flight setup of the cabin pressurization system, as well as improved procedures for interpreting and responding to the cabin altitude/ configuration warning horn. This AD results from reports that airplanes have failed to pressurize, and that the flightcrews failed to react properly to the cabin altitude warning horn. We are issuing this AD to prevent failure of the airplane to pressurize and subsequent failure of the flightcrew to recognize and react to a valid cabin altitude warning horn, which could result in incapacitation of the flightcrew due to hypoxia (lack of oxygen in body) and consequent loss of airplane control.
Airworthiness Directives; Pilatus Aircraft Ltd. Models PC-6, PC-6-H1, PC-6-H2, PC-6/350, PC-6/350-H1, PC-6/350-H2, PC-6/A, PC-6/A-H1, PC-6/A-H2, PC-6/B-H2, PC-6/B1-H2, PC-6/B2-H2, PC-6/B2-H4, PC-6/C-H2, and PC-6/C1-H2 Airplanes
We are adopting a new airworthiness directive (AD) that supersedes AD 98-12-01, which applies to certain Pilatus Aircraft Ltd (Pilatus) Models PC-6, PC-6/A, PC-6/B, and PC-6/C series airplanes equipped with turbo-prop engines. Since we issued AD 98-12-01, the FAA determined the action should also apply to all the models of the PC-6 airplanes listed in the type certificate data sheet of Type Certificate (TC) No. 7A15 that were produced in the United States through a licensing agreement between Pilatus and Fairchild Republic Company (also identified as Fairchild Industries, Fairchild Heli Porter, or Fairchild-Hiller Corporation). In addition, the intent of the applicability of AD 98-12-01 was to apply to all the affected serial numbers of the airplane models listed in TC No. 7A15. This AD retains all the actions of AD 98-12-01, adds those Fairchild Republic Company airplanes to the applicability of this AD, and lists the individual specific airplane models. We are issuing this AD to prevent engine fuel starvation during maximum climb and descent caused by poor fuel tank venting with low fuel levels, which could result in a loss of engine power during critical phases of flight.
Airworthiness Directives; McDonnell Douglas Model MD-11 and MD-11F Airplanes
The FAA is superseding an existing airworthiness directive (AD) that applies to certain McDonnell Douglas Model MD-11 and MD-11F airplanes. That AD currently requires replacement of the upper and lower reading lights in the forward crew rest area with a redesigned light fixture. This new AD adds airplanes to the applicability of the existing AD. This AD results from a report of the old reading lights being inadvertently sent to an additional ten airplanes. We are issuing this AD to prevent a possible flammable condition, which could result in smoke and fire in the forward crew rest area.
Airworthiness Directives; Boeing Model 747-400 and 747-400D Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 747-400 and 747-400D series airplanes. This AD requires replacing specified tie rods of the center overhead stowage bins. This AD results from manufacturer analysis of the overhead storage bin support structure that demonstrated that the capability of certain existing tie rods does not meet emergency landing load requirements. We are issuing this AD to prevent detachment of the center overhead stowage bins during an extreme forward load event, which could cause injury to passengers and hinder emergency evacuation procedures.
