Airworthiness Directives; Boeing Model 737-600, 737-700, 737-700C, 737-800, and 737-900 Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 737-600, 737-700, 737-700C, 737-800, and 737- 900 series airplanes. This proposed AD would require an inspection of the vertical fin lugs, skin, and skin edges for discrepancies, an inspection of the flight control cables, fittings, and pulleys in section 48 for signs of corrosion, an inspection of the horizontal stabilizer jackscrew, ball nut, and gimbal pins for signs of corrosion, and corrective actions if necessary. This proposed AD results from reports indicating that moisture was found within the section 48 cavity. We are proposing this AD to ensure that the correct amount of sealant was applied around the vertical fin lugs, skin and the skin edges. Missing sealant could result in icing of the elevator cables, which could cause a system jam and corrosion of structural and flight control parts, resulting in reduced controllability of the airplane.
Airworthiness Directives; McDonnell Douglas Model DC-10-10 and DC-10-10F Airplanes, Model DC-10-15 Airplanes, Model DC-10-30 and DC-10-30F (KC-10A and KDC-10) Airplanes, Model DC-10-40 and DC-10-40F Airplanes, Model MD-10-10F and MD-10-30F Airplanes, and Model MD-11 and MD-11F Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for all McDonnell Douglas airplane models identified above. This proposed AD would require revising the FAA-approved maintenance program, or the Airworthiness Limitations (AWLs) section of the Instructions for Continued Airworthiness, as applicable, to incorporate new AWLs for fuel tank systems to satisfy Special Federal Aviation Regulation No. 88 requirements. For certain airplanes, this proposed AD would also require the initial accomplishment of a certain repetitive AWL inspection to phase in that inspection, and repair if necessary. This proposed AD results from a design review of the fuel tank systems. We are proposing this AD to prevent the potential for ignition sources inside fuel tanks caused by latent failures, alterations, repairs, or maintenance actions, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.
Airworthiness Directives; ATR Model ATR42 and ATR72 Airplanes
This document announces a reopening of the comment period for the above-referenced NPRM. The NPRM proposed the adoption of a new airworthiness directive for all ATR Model ATR42 and ATR72 airplanes. That NPRM invites comments concerning the proposed requirements for revising the Airworthiness Limitations Section of the Instructions for Continued Airworthiness to incorporate new limitations for fuel tank systems. This reopening of the comment period is necessary to provide additional opportunity for public comment on the proposed requirements of that NPRM.
Automatic Dependent Surveillance-Broadcast (ADS-B) Out Performance Requirements to Support Air Traffic Control (ATC) Service; Extension of Comment Period
This action extends the comment period for an NPRM that was published on October 5, 2007. In that document, the FAA proposed performance requirements for certain avionics equipment on aircraft operating in specified classes of airspace within the United States National Airspace System. This extension is a result of requests from the: Air Transport Association of America, Inc., Air Carrier Association of America, Civil Aviation Aerospace Industries Association, National Air Carrier Association, and Regional Airline Association; Aircraft Owners and Pilots Association; and Cargo Airline Association to extend the comment period to the proposal.
Airworthiness Directives; Boeing Model 767-200, -300, -300F, and -400ER 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 reworking the surface of the ground stud bracket of the left and right transformer rectifier units (TRUs) and the airplane structure mounting surface, and measuring the resistance from the bracket to the structure and the ground lugs to the bracket using a bonding meter. This proposed AD would revise the applicability of the existing AD to include additional airplanes and would also require, among other actions, installation of a new ground stud bracket using faying surface bonding. This proposed AD results from a report of loss of all direct current (DC) power generation during a flight, due to inadequate electrical ground path between the ground bracket of the TRUs/main battery charger (MBC) and the structure. We are proposing this AD to prevent depletion of the main battery while in flight, resulting from the loss of both TRUs and the MBC, and consequent loss of all DC power, which could impact the safe flight and landing of the airplane due to the loss of function or malfunction of essential/critical systems and displays in the cockpit.
Airworthiness Directives; Boeing Model 747-100, -100B, -100B SUD, -200B, -200C, -200F, -300, 747SP, and 747SR Series Airplanes Powered by General Electric (GE) CF6-45/50 and Pratt & Whitney (P&W) JT9D-70, JT9D-3 or JT9D-7 Series Engines
The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 747-100, -100B, -100B SUD, -200B, -200C, - 200F, -300, 747SP, and 747SR series airplanes powered by General Electric (GE) CF6-45/50 and Pratt & Whitney (P&W) JT9D-70, JT9D-3 or JT9D-7 series engines. This proposed AD would require repetitive inspections to find cracks and broken fasteners of the rear engine mount bulkhead of the inboard and outboard nacelle struts, and repair if necessary. For certain airplanes, this proposed AD mandates a terminating modification for certain inspections of the inboard and outboard nacelle struts. This proposed AD results from reports of web and frame cracks and sheared attachment fasteners on the inboard and outboard nacelle struts. We are proposing this AD to detect and correct cracks and broken fasteners of the inboard and outboard nacelle struts, which could result in possible loss of the rear engine mount bulkhead load path and consequent separation of the engine from the airplane.

The FAA is issuing this notice to advise the public of RTCA Special Committee 212, Helicopter Terrain Awareness and Warning System (HTWAS).
Notice of Approval of Finding of No Significant Impact (FONSI) on a Short Form Environmental Assessment (EA); Greater Peoria Regional Airport, Peoria, IL
The Federal Aviation Administration (FAA) is issuing this notice to advise the public of the approval of a Finding of No Significant Impact (FONSI) on an Environmental Assessment for proposed Federal actions at Greater Peoria Airport, Peoria, Illinois. The FONSI specifies that the proposed federal actions and local development projects are consistent with existing environmental policies and objectives as set forth in the National Environmental Policy Act of 1969 and will not significantly affect the quality of the environment. A description of the proposed Federal actions is : (a) To issue an environmental finding to allow approval of the Airport Layout Plan (ALP) for the development items listed below; (b) Approval of the Airport Layout Plan (ALP) for the development items listed below; and (c) Establish eligibility of the Greater Peoria Airport Authority to compete for Federal funding for the development projects depicted on the Airport Layout Plan. The specific item in the local airport development project is to acquire approximately 34 acres of land in fee simple title off the Runway 31 end. Copies of the environmental decision and the Short Form EA are available for public information review during regular business hours at the following locations: 1. Greater Peoria Regional Airport, 6100 West Everett McKinley Dirksen Parkway, Peoria, Illinois 61607. 2.
