Federal Aviation Administration July 2007 – Federal Register Recent Federal Regulation Documents

We are adopting a new airworthiness directive (AD) that supersedes AD 2006-22-08, which applies to all Air Tractor, Inc. (Air Tractor) Models AT-602, AT-802, and AT-802A airplanes. AD 2006-22-08 currently requires you to repetitively inspect the engine mount for any cracks, repair or replace any cracked engine mount, and report any cracks found to the FAA. Since we issued AD 2006-22-08, the FAA has received reports of two Model AT- 802A airplanes with cracked engine mounts below the initial compliance time in AD 2006-22-08. The FAA has determined that an initial inspection is required when the airplane reaches a total of 1,300 hours time-in-service (TIS) instead of 4,000 hours TIS required by AD 2006- 22-08. Consequently, this AD retains the actions of AD 2006-22-08 while requiring the initial inspection when the airplane reaches a total of 1,300 hours TIS. We are issuing this AD to detect and correct cracks in the engine mount, which could result in failure of the engine mount. Such failure could lead to separation of the engine from the airplane.

We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued 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:

This action revises Class E airspace at Red Dog, AK to provide adequate controlled airspace to contain aircraft executing Instrument Approach Procedures. Two Area Navigation (RNAV) Required Navigation Performance (RNP) Special Instrument Approach Procedures and an RNAV RNP Special Departure Procedure (DP) are being developed for the Red Dog Airport. This action revises existing Class E airspace upward from 1,200 feet (ft.) above the surface at Red Dog Airport, Red Dog, AK.

The FAA invites public comments about our intention to request the Office of Management and Budget's (OMB) revision of a current information collection. The Federal Register Notice with a 60-day comment period soliciting comments on the following collection of information was published on March 26, 2007, vol. 72, no. 57, page 14162. This collection establishes requirements for the certification, operation, and maintenance of light-sport aircraft.

The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 777-200, -200LR, -300, and -300ER series airplanes. This proposed AD would require revising the Airworthiness Limitations (AWLs) section of the Instructions for Continued Airworthiness by incorporating new limitations for fuel tank systems to satisfy Special Federal Aviation Regulation No. 88 requirements. This proposed AD also would require the initial performance of certain repetitive inspections specified in the AWLs to phase in those inspections, 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 fuel tank explosions and consequent loss of the airplane.

The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 767-200, -300, -300F, and -400ER series airplanes. This proposed AD would require revising the FAA-approved maintenance program to incorporate new airworthiness limitations (AWLs) for fuel tank systems to satisfy Special Federal Aviation Regulation No. 88 requirements. This proposed AD would also require the initial inspection of certain repetitive AWL inspections to phase in those inspections, 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.

The FAA proposes to adopt a new airworthiness directive (AD) for all Boeing Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747- 200C, 747-200F, 747-300, 747SR, and 747SP series airplanes. This proposed AD would require revising the FAA-approved maintenance program by incorporating new airworthiness limitations (AWLs) for fuel tank systems to satisfy Special Federal Aviation Regulation No. 88 requirements. This proposed AD would also require the initial inspection of certain repetitive AWL inspections to phase in those inspections, and repair if necessary.

This action revises area navigation (RNAV) route Q-22 over the South Central United States by changing a waypoint name to eliminate confusion with similar sounding waypoints in close proximity to each other. The FAA is taking this action to enhance safety and to improve the efficient use of the navigable airspace.

This action confirms the effective date of a direct final rule that establishes a Class E airspace area at Dean Memorial Airport, Haverhill, NH (K5B9) to provide for adequate controlled airspace for those aircraft using the new Area Navigation (RNAV) Instrument Approach Procedure to the Airport.

This action revises Restricted Areas 3601A (R-3601A) and 3601B (R-3601B), at Brookville, KS, in response to a request from the United States Air Force (USAF). Specifically, this action revises R-3601A and R-3601B by combining their lateral boundaries, expanding the ceiling to flight level 230 (FL230), and re-designating the lower portion of the combined area as R-3601A and the upper portion as R-3601B. Additionally, this action changes the using agency of R-3601A and R- 3601B from ``Commander, Kansas ANG, McConnell AFB, KS'' to ``Air National Guard, 184th Air Refueling Wing, Detachment 1, Smoky Hill ANG Range, Salina, KS.'' These revisions will fulfill new USAF requirements for high altitude release bomb training for fighter aircraft and medium-to-high altitude release bomb training for bombers.

The FAA is issuing this notice to advise the public of a meeting of RTCA Special Committee 207, Airport Security Access Control Systems.
