Establishment of Class E Airspace; Fort Kent, ME
This action confirms the effective date of a direct final rule published in the Federal Register (73 FR 9451) that establishes Class E Airspace at Fort Kent, ME to support a new Area Navigation (RNAV) Global Positioning System (GPS) Special Instrument Approach Procedure (IAP) that has been developed for medical flight operations into the Northern Maine Medical Center.
Crewmember and Dispatcher Training Programs
The FAA is issuing this technical amendment to reserve subparts BB and CC in 14 CFR part 121. The FAA is engaged in rulemaking and anticipates codifying the new regulations in part 121 subparts BB and CC.
Petition for Rulemaking-Classification of Polyurethane Foam and Certain Finished Products Containing Polyurethane Foam as Hazardous Materials
On March 30, 2007, PHMSA published a notice soliciting comments on the merits of a petition for rulemaking filed by the National Association of State Fire Marshals (NASFM). The petitioner asked PHMSA to designate polyurethane foam and certain finished products containing polyurethane foam as hazardous materials when transported in commerce as a matter of safety for emergency responders and the general public. PHMSA is re-opening the comment period so that interested persons may submit additional comments on the March 30, 2007 notice and on supplemental information submitted by the petitioner. The comment period will remain open until further notice is published in the Federal Register.
Airworthiness Directives; Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) 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) 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:
Proposed Agency Information Collection Activities; Comment Request
In compliance with the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.), this notice announces that the Information Collection Requirements (ICRs) abstracted below have been forwarded to the Office of Management and Budget (OMB) for review and comment. Each ICR describes the nature of the information collection and its expected burden. The Federal Register notice with a 60-day comment period soliciting comments on the collections of information listed below was published on February 26, 2008 (See 73 FR 10322).
Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-135ER, -135KE, -135KL, and -135LR Airplanes, and Model EMB-145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP Airplanes
We are revising an earlier NPRM for the products listed above. This action revises the earlier NPRM by expanding the scope. 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:

Airworthiness Directives; Boeing Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-200C, 747-200F, 747-300, 747-400, 747SR, and 747SP Series Airplanes
The FAA is revising an earlier NPRM for an airworthiness directive (AD) that applies to certain Boeing Model 747 series airplanes. The original NPRM would have superseded an existing AD that currently requires inspecting to detect cracking in certain lower lobe fuselage skin lap joints, doing repetitive inspections for cracking at certain fastener locations having countersunk fasteners, and replacing countersunk fasteners with protruding head fasteners at certain fastener locations. The original NPRM proposed to replace a previous high-frequency eddy current (HFEC) inspection method with a new HFEC inspection method, add a one-time inspection for cracking of certain airplanes, and terminate the adjustment factor for the inspection compliance times based on cabin differential pressure. The original NPRM also included an inspection at an additional lap joint. The original NPRM resulted from reports of fuselage skin cracks found at certain countersunk fastener locations in the upper row of lap joints near the wing-to-body fairings, and from a report that the presence of Alodine-coated rivets could cause faulty results during the required inspections using the optional sliding probe HFEC inspection method specified in the existing AD. This new action revises the original NPRM by including inspections at additional lap joint locations and by removing inspections at certain other lap joint locations. We are proposing this supplemental NPRM to prevent reduced structural integrity of the fuselage.
Airworthiness Directives; Boeing Model 777-200 Series Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Boeing Model 777-200 series airplanes. This proposed AD would require repetitive inspections for any wrinkle in certain external skin panels, and for cracking at the fuselage bulkhead shear tie end fastener locations at certain stations of section 48 of the fuselage; and doing related investigative and corrective actions if necessary. This proposed AD results from a report of cracks found in the external skin on the left and right sides of the Section 48 panel of the fuselage on two airplanes with skin wrinkles found at two of the external crack locations. We are proposing this AD to detect and correct wrinkles and cracks in certain external skin panels of Section 48, which could join together and result in reduced structural integrity of support structure for the vertical and horizontal stabilizers and inability of the airplane to sustain limit loads.
Environmental Impact Statement: Mobile County, AL
The FHWA is issuing this notice to advise the public that the Notice of Intent published on August 28, 2002, to prepare an Environmental Impact Statement (EIS) for a proposed highway project in Mobile County, Alabama is being rescinded.
Airworthiness Directives; CFM International, S.A. CFM56-5B1/P; -5B2/P; -5B3/P; -5B3/P1; -5B4/P; -5B4/P1; -5B5/P; -5B6/P; -5B7/P; -5B8/P; and -5B9/P Turbofan Engines
The FAA proposes to adopt a new airworthiness directive (AD) for CFM International, S.A. CFM56-5B1/P; -5B2/P; -5B3/P; -5B3/P1; -5B4/ P; -5B4/P1; -5B5/P; -5B6/P; -5B7/P; -5B8/P; and -5B9/P turbofan engines. This proposed AD would require initial and repetitive eddy current inspections (ECIs) of certain part number (P/N) low-pressure (LP) turbine rear frames. This proposed AD results from a refined lifing analysis by the engine manufacturer that shows the need to identify initial and repetitive inspection thresholds for inspecting certain LP turbine rear frames. We are proposing this AD to detect low- cycle-fatigue cracks in the LP turbine rear frame, which could result in engine separation from the airplane, possibly leading to loss of control of the airplane.
