Railroad Grade Crossing Safety; Withdrawal
FMCSA withdraws a July 30, 1998, Notice of Proposed Rulemaking (NPRM) that would have prohibited the driver of a commercial motor vehicle (CMV) from driving onto a highway-railroad grade crossing without sufficient space to drive completely through the crossing without stopping. The NPRM was issued in response to section 112 of the Hazardous Materials Transportation Authorization Act of 1994. After careful analysis and review of the comments, FMCSA has concluded that the NPRM gave a misleading impression of the statutory mandate and the cost and complexity of complying with an implementing regulation. FMCSA is therefore withdrawing the 1998 NPRM in order to eliminate the confusion associated with this rulemaking. The agency, however, will issue a simpler and more clearly written new NPRM addressing the requirements of section 112.
Federal Motor Vehicle Safety Standards; Occupant Crash Protection
This document denies a petition for rulemaking submitted by Mr. James E. Hofferberth asking the agency to take a variety of steps related to incorporating dummies representing three-year-old, six-year- old and ten-year-old children and 95th percentile adult males into the agency's frontal crash test programs.
Airworthiness Directives; Mitsubishi Heavy Industries MU-2B Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for all Mitsubishi Heavy Industries (MHI) MU-2B series airplanes. This proposed AD would require you to do flight checks of the rigging of the engine and propeller systems. This proposed 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 proposed AD to detect and correct improper adjustment of the flight idle fuel flow setting. This condition, if uncorrected, could result in degraded performance and poor handling qualities with consequent loss of control of the airplane in certain situations.
Airworthiness Directives; Mitsubishi Heavy Industries MU-2B Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Mitsubishi Heavy Industries (MHI) MU-2B series airplanes. This proposed AD would require you to incorporate power assurance charts into the Limitations Section of the Airplane Flight Manual (AFM), inspect the engine torque indication system, and recalibrate the torque pressure transducers as required. This proposed AD results from a recent safety evaluation that used a data-driven approach to analyze 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 proposed AD to detect and correct torque transducers that are out of calibration. The above issue, if uncorrected, could result in degraded performance and poor handling qualities with consequent loss of control of the airplane in certain situations.
National Environmental Policy Act (NEPA) Implementing Instructions for Airport Actions
The Federal Aviation Administration's Office of Airports (ARP) has updated and revised its instructions for implementing the National Environmental Policy Act (NEPA) for airport actions. ARP is replacing Order 5050.4A, Airport Environmental Handbook with the updated and revised instructions in Order 5050.4B, National Environmental Policy Act (NEPA) Implementing Instructions for Airport Actions. This Notice announces the availability of Order 5050.4B and its Preamble. The documents are available at ARP's Web site https://www.faa.gov/ airportsairtraffic/ airports. Although APR is presenting the Preamble on its Web site, it is not including the text of that document in this Notice. ARP expects to publish the text in the Federal Register within the next 10 days. This delay is due to publication procedures associated with the extensively detailed Preamble.
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. The purpose of this notice is to improve the public's awareness of, and participation in, this aspect of FAA's regulatory activities. Neither publication of this notice nor the inclusion or omission of information in the summary is intended to affect the legal status of any petition or its final disposition.
Notice of Request for Comments on Extension of Currently Approved Information Collections: OMB Control Numbers 2126-0032 and 2126-0033 (Financial and Operating Statistics for Motor Carriers of Property)
In accordance with the Paperwork Reduction Act of 1995 FMCSA announces its intent to submit two currently-approved Information Collection Requests (ICRs) described to the Office of Management and Budget (OMB) for review and approval. The ICRs describes two information collection activities and their expected costs and burdens. The Federal Register notice allowing for a 60-day comment period on the ICRs was published on January 18, 2006 (71 FR 2985). The agency received five comments in support of the continuation of these ICRs.
Notice of Request for Approval To Collect New Information: Confidential Close Call Reporting System
In accordance with the requirements of section3506(c)(2)(A) of the Paperwork Reduction Act of 1995, this notice announces that the Bureau of Transportation Statistics (BTS) intends to request the Office of Management and Budget (OMB) to approve a new information collection effort in railroad yards. This data collection effort is in support of a five-year research study aiming at improving rail safety by analyzing information on close calls and other unsafe occurrences in the rail industry. The study is conducted by the Office of Human Factors in the Federal Railroad Administration and is designed to identify safety issues and propose corrective actions based on voluntary reports of close calls submitted to BTS. This collection is necessary because data on close calls are not normally reported to the railroad carriers or the Federal Railroad Administration.

Notice of Final Federal Agency Actions on Proposed Highway in Ohio
This notice announces actions taken by the FHWA and other Federal agencies that are final within the meaning of 23 U.S.C. 139(l)(1). The actions relate to a proposed highway project, U.S. Route 24, from east of the IR469 bypass in New Haven, Indiana, Allen County, Indiana to SR424 west of Defiancé, Ohio. Those actions grant licenses, permits, and approvals for the project.
Draft General Conformity Determination for Proposed Operations of Southwest Airlines Co. at Denver International Airport, Denver, CO
The FAA is issuing this notice to advise the public that a Draft General Conformity Determination (DGCD) for Proposed Operations of Southwest Airlines Co. (Southwest) at Denver International Airport (DEN) has been prepared. In accordance with Section 176(c) of the Clean Air Act, FAA has assessed whether the emissions that would result from FAA's action in approving the proposed operation specifications (OpSpec) for Southwest's proposed operations at DEN conform with the Colorado State Implementation Plan (SIP).
Notice of Submission Deadline for International Slots for the Winter 2006 Scheduling Season
On October 1, 1999, the FAA amended the regulations governing takeoff and landing slots and slot allocation procedures at certain High Density Traffic Airports as a result of the ``Open Transborder'' Agreement between the Government of the United States and the Government of Canada. One element of this final rule established that the deadline for submission of requests for international slots will be published in a Federal Register notice for each scheduling season. The purpose of the amendment is for the FAA deadline for international slots requests to coincide with the International Air Transport Association (IATA) deadline for submission of slot requests. In accordance with this amendment, the FAA announces in this notice that the deadline for submitting requests for international slots at John F. Kennedy International Airport (JFK) for allocation under 14 CFR 93.217 is May 11, 2006. The FAA will allocate international slots through December 31, 2006 only, as the High Density Rule expires at JFK on December 31, 2006. (See 49 U.S.C. 41715(a)(2).) After that date, slots will no longer be required for operation at JFK. The FAA has designated Chicago's O'Hare International Airport (O'Hare) as a Level 2, Schedules Facilitated Airport under the IATA Guidelines and will review international operations based on runway parameters. The FAA requests carriers intending to conduct international service at O'Hare for the Winter 2006/07 Scheduling Season to submit their intended schedules following the same procedures used for submitting requests for slots at JFK. Carriers are advised that this notice does not alter or change any coordination procedures conducted by the City of Chicago for O'Hare's Terminal 5 facilities. Finally, the U.S. scheduling season is consistent with the changes in daylight savings time. In accordance with the Energy Policy Act of 2005 (Pub. L. 109-58), daylight savings time will begin on March 11, 2007 and end on November 3, 2007. The IATA Northern Winter Scheduling Season will end on March 24, 2007, and its Summer Scheduling Season will only begin on March 25, 2007. There is a two-week period for which the IATA Winter scheduling season will overlap with the U.S. summer scheduling season. We recognize this transition period will cause some carriers to adjust scheduled times based on their network requirements and other considerations. For O'Hare, the FAA will accept carriers' schedule requests for the entire IATA Northern Winter Scheduling Season (ending on March 24, 2007), even though that will be the first two weeks of the U.S. summer scheduling season. This will facilitate carriers seeking to confirm schedules at other worldwide slot coordinated airports in accordance with the IATA season and coordination process. Carriers should clearly indicate any schedule differences during the March 11 to 24, 2007, period. The FAA intends to provide the maximum practical flexibility to accommodate schedule adjustments during this period and does not anticipate any significant issues regarding historic rights due to the earlier introduction of daylight saving time in the U.S. A deadline for submitting the reamining summer schedules for 2007 will by announced in the Federal Register by September 2006. The Department of Transportation reserves the right to withhold the approval of schedules to any foreign air carrier of a country that does not provide equivalent rights of access to its airports for U.S. air carriers, as determined by the Secretary of Transportation.
Notice of Final Federal Ageny Actions on Proposed Highway in Alaska
This notice announces actions taken by the FHWA and other Federal agencies that are final within the meaning of 23 U.S.C. 139(l)(1). The actions relate to a proposed highway project, the East Lynn Canal Highway, Alaska Route Number 7, from Echol Cove to Katz Point in the Haines and Juneau Boroughs, State of Alaska. Those actions grant licenses, permits, and approvals for the project.
Environmental Impact Statement: Butler County, PA
This notice rescinds the previous Notice of Intent (issued October 3, 2001Vol. 66, No. 192) to prepare an Environmental Impact Statement for a proposed highway project in Butler County.
Airworthiness Directives; MD Helicopters, Inc. Model 600N Helicopters
This amendment supersedes an existing airworthiness directive (AD) for the MD Helicopters, Inc. (MDHI) Model 600N helicopters, that currently requires inspecting both upper tailboom attachment fittings, nut plates and both angles for a crack or thread damage, and repairing or replacing any cracked or damaged part. That AD also requires replacing the upper right tailboom attachment bolt with a new attachment bolt, and if the upper right attachment bolt is broken, replacing the three remaining attachment bolts with airworthy bolts. Adding a washer to each bolt and modifying both access covers is also required. Thereafter, inspecting the upper tailboom attachments and repairing or replacing any cracked part is required by that AD. That AD was prompted by the discovery of a cracked attachment bolt on a helicopter. This AD requires those same actions, plus installing additional inspection holes in the aft fuselage skin panels and inspecting the upper and lower tailboom attachment fittings, the upper longerons, and the angles and nut plates for cracks. It also requires, within a specified time, replacing the upper right tailboom attachment fitting, painting the inspection area, and replacing existing nut plates. Additionally, it requires inspecting the attachment bolts for any damage or wear. This amendment is prompted by an accident involving a Model 600N helicopter. The actions specified by this AD are intended to prevent failure of the tailboom attachment fittings, separation of the tailboom from the helicopter, and subsequent loss of control of the helicopter.
Environmental impact statement: Gaston and Mecklenburg Counties, NC
The FHWA is issuing this notice to advise the public that an environmental impact statement will be prepared for a proposed highway project in Gaston and Mecklenburg Counties, North Carolina.

Special Conditions: Airbus Model A380-800 Airplane; Discrete Gust Requirements
This document corrects an error that appeared in Docket No. NM316, Special Conditions No. 25-312-SC, which were published in the Federal Register on January 24, 2006 (71 FR 3753). The error is in the Special Conditions No. and is being corrected herein.
Sixth Meeting: RTCA Special Committee 207/Airport Security Access Control Systems
The FAA is issuing this notice to advise the public of a meeting of RTCA Special Committee 207, Airport Security Access Control Systems.
Airworthiness Directives; Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. This AD requires modifying the wiring on an alternating current (AC) service bus contactor that is located in the avionics bay. This AD results from incidents of short circuit failures of certain AC contactors located in the avionics bay. We are issuing this AD to prevent short circuit failures of certain AC contactors, which could result in arcing and consequent smoke or fire.
Airworthiness Directives; Pratt & Whitney JT9D-7R4G2 Turbofan Engines
The FAA proposes to adopt a new airworthiness directive (AD) for Pratt & Whitney (PW) JT9D-7R4G2 turbofan engines. This proposed AD would require replacing the old configuration 2nd stage high pressure turbine (HPT) air seal assembly with a new design 2nd stage HPT air seal assembly that increases cooling air flow. This proposed AD results from a report of an uncontained failure of the 2nd stage air seal assembly, caused by the air seal assembly brace disengaging from the air seal, due to insufficient cooling air flow. We are proposing this AD to prevent uncontained failure of the 2nd stage HPT air seal assembly, leading to engine in-flight shutdown and damage to the airplane.
Airworthiness Directives; Boeing Model 757-200 and -200PF Series Airplanes Equipped With Pratt & Whitney Engines
The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 757-200 and -200PF series airplanes equipped with Pratt & Whitney engines. This AD requires repetitive detailed inspections to detect and correct any gap between the strut fitting and the forward engine mount assembly and applicable related investigative actions, corrective actions, and other specified actions. This AD results from a report indicating that gaps had been found between the strut fitting and the forward engine mount assembly. We are issuing this AD to detect and correct any gaps between the strut fitting and the forward engine mount assembly of both engines, which could result in separation of the engine from the wing and subsequent loss of control of the airplane.
Airworthiness Directives; Boeing Model 727, 727C, 727-100, and 727-100C Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for all Boeing Model 727, 727C, 727-100, and 727-100C series airplanes. This AD requires repetitive inspections for cracks in the body skin and bear strap at the upper and lower hinge cutouts of the mid-cabin galley doorway, along the upper fastener row of the stringer 14R lap splice, and in the doorstop fitting adjacent to the upper hinge cutout; and corrective action if necessary. This AD also provides for optional terminating action for certain inspections. This AD results from reports of skin and bear strap cracking at the upper and lower hinge cutout and along the upper fastener row of the stringer 14R lap splice, and cracking in the doorstop fitting adjacent to the upper hinge cutout. There are also reports of cracking on airplanes previously modified in production to resist such cracking. We are issuing this AD to find and fix fatigue cracking of the fuselage, which could result in reduced structural integrity and consequent rapid decompression of the airplane.
Traffic Control Devices on Federal-Aid and Other Streets and Highways; Standards
The FHWA proposes to revise its regulation that prescribes procedures for obtaining basic uniformity of traffic control devices on Federal-aid and other streets and highways. This notice of proposed rulemaking makes some nomenclature changes, provides clarification on the meaning of ``substantial conformance'' and ``roads open to public travel,'' and removes certain outdated references.
Environmental Impact Statement: Pellissippi Parkway Extension (State Route 162), Blount County, TN
The Federal Highway Administration (FHWA) is issuing this notice to advise the public that an Environmental Impact Statement (EIS) will be prepared for a proposed highway project in Blount County, Tennessee.
Decision That Nonconforming 2003 Audi RS6 and RS6 Avant Passenger Cars Are Eligible for Importation
This document announces a decision by the National Highway Traffic Safety Administration (NHTSA) that certain 2003 Audi RS6 and RS6 Avant passenger cars that were not originally manufactured to comply with all applicable Federal motor vehicle safety standards (FMVSS) are eligible for importation into the United States because they are substantially similar to vehicles originally manufactured for importation into and sale in the United States and that were certified by their manufacturer as complying with the safety standards (the U.S. certified version of the 2003 Audi RS6 and RS6 Avant passenger cars), and they are capable of being readily altered to conform to the standards.
Hazardous Materials: Requirements for Lighters and Lighter Refills
On January 23, 2006, PHMSA published a final rule entitled ``Requirements for Lighters and Lighter Refills'' that amended requirements in the Hazardous Materials Regulations pertaining to the examination, testing, certification, and transportation of lighters and lighter refills. In response to appeals submitted by persons affected by the final rule, this final rule amends requirements applicable to the transportation of lighter refills and allows for immediate voluntary compliance with certain provisions.
Notice of Intent To Rule on Request To Release Airport Property at Searcy County Municipal Airport, Marshall, Arkansas
The FAA proposes to rule and invites public comment on the release of land at the Searcy County Municipal Airport under the provisions of Title 49 United States Code, Section 47153.
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 propose to revise Airworthiness Directive (AD) 68-17-03, which applies to all Pilatus Aircraft Ltd. PC-6 series airplanes. AD 68-17-03 currently requires you to repetitively inspect the rudder end rib for cracks and replace the rudder end rib with a modified rudder end rib when you find cracks. Installing the modified rudder end rib terminates the repetitive inspection requirements of AD 68-17-03. Under a licensing agreement with Pilatus, Fairchild Republic Company (also identified as Fairchild Industries, Fairchild Heli Porter, or Fairchild-Hiller Corporation) produced Model PC-6 series airplanes (manufacturer serial numbers 2001 through 2092) in the United States. AD 68-17-03 was intended to apply to all affected serial numbers of Model PC-6 series airplanes listed on Type Certificate Data Sheet (TCDS) No. 7A15, including the Fairchild-produced airplanes. Consequently, this proposed AD would clarify that all models of the PC- 6 airplane on TCDS No. 7A15 (including those models produced under the licensing agreement by Fairchild Republic Company) are included in the applicability. We are proposing this AD to detect and correct cracks in the rudder end rib, which could result in failure of the rudder end rib. This failure could result in loss of directional control.
Airworthiness Directives; Mitsubishi Heavy Industries MU-2B Series Airplanes
The FAA proposes to revise an earlier proposed airworthiness directive (AD) that applies to all Mitsubishi Heavy Industries MU-2B series airplanes. The earlier NPRM would have required 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; replace any deformed or irregular parts; and install new or reusable parts and torque to the correct value. The earlier NPRM resulted 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. This proposed AD would retain the actions from the earlier NPRM, add airplanes to the applicability, revise the serial numbers of the affected airplanes, and update the manufacturer's contact information. This proposed AD results from the manufacturer revising the service information to include two additional airplane models. Since these actions impose an additional burden over that proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on these additional actions.
Availability of a Draft FONSI/FONPA
The purpose of this Notice is to make available to the public the draft Finding of No Significant Impact/Finding of No Practicable Alternative (FONSI/FONPA) for the Port of Anchorage Intermodal Expansion, North End Runway Material Extraction and Transport Project (Project). A draft Environmental Assessment (EA), dated March 2006, was prepared that analyzed the potential impacts on the human and natural environment associated with the proposed material extraction activities at the North End Borrow Site and potential transportation corridors located on Elmendorf Air Force Base (EAFB). A final EA and a final FONSI/FONPA will be published once comments have been properly addressed. This environmental documentation supports the proposed expansion of the Port of Anchorage (POA), which includes a variety of activities to enhance the transportation of goods and people within the State of Alaska.
Worker Visibility
The FHWA proposes to require the use of high-visibility safety apparel for workers who are working within the Federal-aid highway rights-of-way. This action would decrease the likelihood of fatalities or injuries to workers on foot who are exposed either to traffic (vehicles using the highway for purposes of travel) or to construction vehicles or equipment while working within the rights-of-ways of Federal-aid highways. This proposal is in response to section 1402 of the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU), Public Law 109-59, 119 Stat. 1227.
Federal Motor Vehicle Safety Standards; Occupant Protection in Interior Impact
Our safety standard on occupant protection in interior impact requires, in part, that light vehicles provide head protection when an occupant's head strikes upper interior components, such as pillars, side rails, headers, and the roof during a crash. For altered vehicles and vehicles built in two or more stages, these requirements become effective September 1, 2006. The Recreation Vehicle Industry Association and the National Truck Equipment Association petitioned the agency to permanently exclude certain types of altered vehicles and vehicles manufactured in two or more stages from these requirements. This document responds to these petitions for rulemaking and proposes certain amendments to the standard. Based on a careful consideration of both the safety benefits of the upper interior protection requirements, and practicability concerns relating to vehicles built in two or more stages and certain altered vehicles, we are proposing to limit these requirements to only the front seating positions of those vehicles. Further, we tentatively conclude that it is appropriate to exclude a narrow group of multi- stage vehicles delivered to the final stage manufacturer without an occupant compartment, because of impracticability concerns. We are also proposing to delay the effective date of the head impact protection requirements as they apply to final stage manufacturers and alterers until September 1, 2008.
Revision of Class E Airspace; Herlong, CA
This final rule will revise the Class E airspace area at Herlong, CA. Additional controlled airspace is necessary for the safety of Instrument Flight Rules (IFR) aircraft during airborne holding. Holding airspace is designed with specific altitudes and lateral boundaries within controlled airspace. This airborne holding procedure is also an integral part of a new Area Navigation (RNAV) Global Positioning System (GPS) Standard Instrument Approach Procedure (SIAP) at the Amedee Army Air Field (AFF), Herlong, CA.
Establishment of Class E Airspace; Galbraith Lake, AK
This action establishes Class E airspace at Galbraith Lake, AK to provide adequate controlled airspace to contain aircraft executing two amended Special Standard Instrument Approach Procedures (SIAPs). This rule results in new Class E airspace established upward from 700 feet (ft.) above the surface at Galbraith Lake, AK.
Revision of Class E Airspace; Middleton Island, AK
This action revises Class E airspace at Middleton Island, AK to provide adequate controlled airspace to contain aircraft executing two new and two amended Standard Instrument Approach Procedures (SIAPs). This rule results in revised Class E airspace established upward from 700 feet (ft.) and 1,200 ft. above the surface at Middleton Island, AK.
Establishment of Class E Airspace; Kuparuk, AK
This action establishes Class E airspace at Kuparuk, AK to provide adequate controlled airspace to contain aircraft executing eight Special Standard Instrument Approach Procedures (SIAPs). This rule results in new Class E airspace established upward from 700 feet (ft.) above the surface at Ugnu-Kuparuk Airport, AK.
Revision of Class E Airspace; Togiak Village, AK
This action revises Class E airspace at Togiak Village, AK to provide adequate controlled airspace to contain aircraft executing two new and two amended Standard Instrument Approach Procedures (SIAPs). This rule results in revised Class E airspace established upward from 700 feet (ft.) above the surface at Togiak Village, AK.
Establishment of Class E Airspace; Minchumina, AK
This action corrects an error in the airspace description contained in a Final Rule that was published in the Federal Register on Wednesday, April 5, 2006 (71 FR 16997). Airspace Docket No. 05-AAL-41.
Interim Guidelines for Certification and Continued Airworthiness of Unbalanced Control Surfaces With Freeplay and Other Nonlinear Features
The Federal Aviation Administration (FAA) announces the availability of proposed Interim Guidelines for Certification and Continued Airworthiness of Unbalanced Control Surfaces with Freeplay and Other Nonlinear Features.
Agency Information Collection Activity Under OMB Review, Request for Comments; Renewal of an Approved Information Collection Activity, Operating Requirements: Commuter and On-Demand Operation
The FAA invites public comments about our intention to request the Office of Management and Budget's (OMB) renewal of a current information collection. The Federal Register Notices with a 60-day comment period soliciting comments on the following collection of information was published on January 18, 2006, volume 71, 11, page 2982. Standards have been established for the operation of agricultural aircraft and for the dispensing of chemicals, pesticides, and toxic substances. Information collected shows applicant compliance and eligibility for certification by FAA.
Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model ERJ 170 Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain EMBRAER Model ERJ 170 airplanes. This proposed AD would require inspecting for excess sealant applied to the attachment bolts of the negative pressure relief valve, and performing corrective actions if necessary. This proposed AD results from reports that excess sealant was applied to the attachment bolts of the negative pressure relief valve, which interfered with the valve's movable diaphragm. We are proposing this AD to prevent incorrect operation of the negative pressure relief valve, which could result in negative pressures that exceed the structural strength limits of the airframe and lead to reduced structural integrity of the airplane.
Airworthiness Directives; Airbus Model A330-200 and -300, and A340-200 and -300 Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Model A330-200 and -300, and A340-200 and -300 series airplanes. This proposed AD would require modifying certain rotary actuator assemblies for the leading edge slat. This proposed AD results from a leak found at the seal of the torque limiter output shaft of the Type A rotary actuator of leading edge slat No. 1. We are proposing this AD to prevent a decrease in the torque limiter function, which could result in degradation and damage to the attachment bolts of the leading edge slat, loss of the slat, and consequent reduced control of the airplane.
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 propose to supersede Airworthiness Directive (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 certification data sheet of Type Certificate (TC) No. 7A15 that are 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. Consequently, this proposed AD would retain all the actions of AD 2002-21-08, would add those Fairchild Republic Company airplanes to the applicability of this proposed AD, and would list out the individual specific airplane models. We are proposing 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; 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 propose to supersede Airworthiness Directive (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. AD 98-12-01 currently requires you to modify the fuel system to improve the venting between the collector tank, the main wing tanks, and the engine. 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 certification data sheet of Type Certificate (TC) No. 7A15 that are 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 affected serial numbers of the airplane models listed in TC No. 7A15. Consequently, this proposed AD would retain all the actions of AD 98-12-01, would add those Fairchild Republic Company airplanes to the applicability of this proposed AD, and would list out the individual specific airplane models. We are proposing 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.
