Department of Transportation 2011 – Federal Register Recent Federal Regulation Documents

The Federal Highway Administration (FHWA), District of Columbia Division and the District Department of Transportation are announcing the availability for public review of the Environmental Assessment (EA) prepared for the I-395 Air Rights Projects in conjunction with the District Department of Transportation (DDOT). The EA was prepared in compliance with the National Environmental Policy Act of 1969 (NEPA); the Council on Environmental Quality Regulations; and the FHWA Environmental Impact and Related Procedures. The project is also being reviewed under Section 106 of the National Historic Preservation Act and the EA includes a Section 106 Effects Assessment. Interested persons are invited to comment on both the EA and the Effects Assessment.

We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:

We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD would require revising the maintenance program to include new or more restrictive life-limits and inspections. This proposed AD was prompted by changes to the Airworthiness Limitations Section (ALS) of the maintenance manual, which adds life-limits, revises life-limits, or adds inspections not previously identified. We are proposing this AD to limit exposure of flight critical components to corrosion, cracking, or failure due to life-limits, which if not corrected, could result in loss of roll control, fatigue cracking, or loss of structural components.

We propose to supersede two existing airworthiness directives (ADs) that apply to General Electric Company (GE) CF6-45 and CF6-50 series turbofan engines with certain low-pressure turbine (LPT) rotor stage 3 disks installed. The existing ADs currently require inspections of high pressure turbine (HPT) and LPT rotors, engine checks, and surveys. Since we issued those ADs, GE has determined that the low- cycle fatigue (LCF) lives of the LPT rotor stage 3 disks affected by those ADs are below the current published engine manual life limits and has introduced a new LPT rotor stage 3 disk part number. This proposed AD would establish a new lower life limit for the LPT rotor stage 3 disks. We are proposing this AD to prevent critical life-limited rotating engine part failure, which could result in an uncontained engine failure and damage to the airplane.

We are adopting a new airworthiness directive (AD) for certain Model EMB-135ER, -135KE, -135KL, and -135LR airplanes; and Model EMB- 145, -145ER, -145MR, -145LR, -145MP, and -145EP airplanes. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:

We are superseding an existing airworthiness directive (AD) that applies to certain Model A300 B4-600, B4-600R, and F4-600R series airplanes, and Model C4-605R Variant F airplanes (collectively called A300-600 series airplanes). This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:

In accordance with the Paperwork Reduction Act of 1995, FMCSA announces that the Information Collection Request (ICR) described below will be submitted to the Office of Management and Budget (OMB) for emergency approval. FMCSA requests approval of this ICR by 30 days from the publication of this notice. The purpose of this information collection is to assess the current levels of voluntary compliance by motorcoach operators to provide pre-trip safety awareness and emergency preparedness information to passengers and to obtain passenger opinions of the implementation of the pre-trip program and any recommended improvements. The Department of Transportation (DOT) and FMCSA will use this data to further inform future policy and regulatory decisions, as well as other initiatives to improve motorcoach safety in the United States.

The Federal Transit Administration (FTA) and the Metro Gold Line Foothill Extension Construction Authority (the Construction Authority) are issuing this notice to advise the public that the Notice of Intent (NOI) to prepare an Environmental Impact Statement (EIS) for proposed improvements in the Metro Gold Line Foothill Extension Transit Corridor from Azusa to Montclair is being rescinded.

We propose to adopt a new airworthiness directive (AD) for all GE CF6-80C2A1, CF6-80C2A2, CF6-80C2A3, CF6-80C2A5, CF6-80C2A5F, CF6- 80C2A8, CF6-80C2B1, CF6-80C2B1F, CF6-80C2B1F1, CF6-80C2B1F2, CF6- 80C2B2, CF6-80C2B2F, CF6-80C2B3F, CF6-80C2B4, CF6-80C2B4F, CF6-80C2B5F, CF6-80C2B6, CF6-80C2B6F, CF6-80C2B6FA, CF6-80C2B7F, CF6-80C2B8F, CF6- 80C2D1F, CF6-80C2K1F, and CF6-80C2L1F turbofan engines, including engines marked on the engine data plate as CF6-80C2B7F1. This proposed AD was prompted by a report of a supplier shipping a batch of nonconforming No. 3 bearing packings that had incorrect cooling holes, and by subsequent reports of nonconforming No. 3 bearing packings being installed on engines in service. This proposed AD would require a one- time inspection of the No. 3 bearing packing for an incorrect cooling hole size and, if it is found nonconforming, removing the packing and removing certain engine rotating life-limited parts, if they were operated with the wrong packing for a specified number of cycles. We are proposing this AD to prevent an uncontained failure of the high- pressure compressor (HPC) rotor or the low-pressure turbine (LPT) rotor or both, which could cause damage to the airplane.

We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD would require removing from service certain serial number (S/N) fan blades, part number (P/N) 338- 002-114-0. This proposed AD was prompted by a normal quality sampling at CFM that isolated a production batch of fan blades with nonconforming geometry of mid-span shroud tips of the fan blades. This defect would cause the upper panel of the fan blade to be liberated following foreign object damage (FOD) or bird strike, and likely result in an inflight shutdown (IFSD). We are proposing this AD to prevent an IFSD of one or more engines following FOD or a bird strike.

We propose to supersede an existing airworthiness directive (AD) that applies to all RR RB211-Trent 553-61, 553A2-61, 556-61, 556A2-61, 556B-61, 556B2-61, 560-61, 560A2-61, 768-60, 772-60, 772B-60, 875-17, 877-17, 884-17, 884B-17, 892-17, 892B-17, and 895-17 turbofan engines. The existing AD currently requires inspecting the intermediate-pressure (IP) compressor rotor shaft rear balance land for cracks. Since we issued that AD, we received reports of one RB211-Trent 700 and two additional RB211-Trent 800 IP compressor rotor shafts that have been found cracked. This proposed AD would continue to require initial inspections, add additional inspections, and an optional terminating action. The cracking identified above could lead to IP compressor rotor shaft failure, uncontained engine failure, and damage to the airplane. We are proposing this AD to correct the unsafe condition on these products.

This action proposes to amend Class E Airspace at Huntington, WV, as the Huntt Non-Directional Beacon (NDB) has been decommissioned and new Standard Instrument Approach Procedures (SIAPs) have been developed at Tri-State/Milton J Ferguson Field Airport. This action would enhance the safety and airspace management of Instrument Flight Rules (IFR) operations at the airport. This action also would update the geographic coordinates of the airport.

This action establishes Class E Airspace at Nahunta, GA, to accommodate the new Area Navigation (RNAV) Global Positioning System (GPS) Standard Instrument Approach Procedures serving Brantley County Airport. This action enhances the safety and airspace management of Instrument Flight Rules (IFR) operations within the National Airspace System. This action also makes a minor adjustment to the geographic coordinates of the airport.

This action establishes Class E airspace at Palmyra, PA, to accommodate new Area Navigation (RNAV) Global Positioning System (GPS) Standard Instrument Approach Procedures at Reigle Field. This action enhances the safety and management of Instrument Flight Rules (IFR) operations at the airport. This action also makes a minor adjustment to the geographic coordinates of the airport.

We propose to supersede an existing airworthiness directive (AD) that applies to all CPAC, Inc. (type certificate formerly held by Commander Aircraft Corporation, Gulfstream Aerospace Corporation, and Rockwell International) Models 112, 112B, 112TC, 112TCA, 114, 114A, 114B, and 114TC airplanes. The existing AD currently requires a one- time inspection of the elevator spar for cracks and, if any crack is found, either replace with a serviceable elevator spar that is found free of cracks or repair/modify the elevator spar with an FAA-approved method. That AD also requires reporting to the FAA the results of the inspection. Since we issued that AD, using the data collected through the reporting requirement, we have determined there is a need for continued inspections. This proposed AD would require repetitive inspections of the elevator spar for cracks and, if any crack is found, either replace with a serviceable elevator spar that is free of any cracks and/or corrosion or repair/modify the elevator spar with an FAA- approved procedure. We are proposing this AD to correct the unsafe condition on these products.

This action amends the time of designation for restricted areas R-5314A, B, C, D, E, F, H, and J in Dare County, NC, by removing the specific published times on Saturday and Sunday. This change reflects current utilization of the restricted areas and provides increased public access to the area on weekends.

Under the provisions of title 49, U.S.C. Section 47153(c), notice is being given that the FAA is considering a request from the Laurinburg-Maxton Airport Commission to waive the requirement that approximately 20.26 acres of airport property, located at the Laurinburg-Maxton Airport, be used for aeronautical purposes.

This action proposes to modify Class E airspace at Show Low Regional Airport, Show Low, AZ. Controlled airspace is necessary to accommodate aircraft using Area Navigation (RNAV) Global Positioning System (GPS) standard instrument approach procedures at Show Low Regional Airport. The FAA is proposing this action to enhance the safety and management of Instrument Flight Rules (IFR) operations at the airport.

FMCSA announces receipt of applications from 21 individuals for exemption from the prohibition against persons with insulin-treated diabetes mellitus (ITDM) operating commercial motor vehicles (CMVs) in interstate commerce. If granted, the exemptions would enable these individuals with ITDM to operate CMVs in interstate commerce.

FMCSA announces its decision to renew the exemptions from the vision requirement in the Federal Motor Carrier Safety Regulations for 17 individuals. FMCSA has statutory authority to exempt individuals from the vision requirement if the exemptions granted will not compromise safety. The Agency has concluded that granting these exemption renewals will provide a level of safety that is equivalent to or greater than the level of safety maintained without the exemptions for these commercial motor vehicle (CMV) drivers.

The FAA is correcting an airworthiness directive (AD) that published in the Federal Register. That AD applies to the products listed above. The effective date in paragraph (a) of the Amended section of the AD is incorrect. This document corrects that error. In all other respects, the original document remains the same.
