Federal Aviation Administration January 25, 2007 – Federal Register Recent Federal Regulation Documents

The FAA is adopting a new airworthiness directive (AD) for certain Bombardier Model DHC-8-400 series airplanes. This AD requires inspecting for fouling and chafing damage of the outboard brake control cable of the main landing gear, replacing the control cable if necessary, reworking the control cable cover, and, if applicable, manufacturing/installing an offset plate on the control cable cover. This AD results from a review of brake control cable operation conducted by the manufacturer. We are issuing this AD to prevent abrasion and wear of the outboard brake control cable, which could lead to cable separation and reduced control of airplane braking.

The FAA is superseding an existing airworthiness directive (AD), which applies to certain Bombardier Model DHC-8-400 series airplanes. That AD currently requires revising the airplane flight manual (AFM) to advise the flightcrew of appropriate procedures to follow in the event that a main landing gear (MLG) fails to extend following a gear-down selection. That AD also currently requires repetitive replacement of the left and right MLG uplock assemblies with new assemblies; and an inspection of the left and right MLG uplock rollers for the presence of an inner low friction liner, and corrective actions if necessary. This new AD revises the requirement for replacing the left and right MLG uplock assemblies by allowing replacement with alternative parts. For a certain MLG uplock assembly, this new AD requires repetitive inspections of the uplock hatch lower jaw for the presence of a wear groove and replacement with an improved part if necessary. For a certain MLG uplock assembly, this new AD requires repetitive inspections of the uplock roller to ensure that it rotates freely and replacement with a new part if necessary. This new AD allows optional replacement of the left and right MLG uplock assemblies with improved parts, which ends the requirements of the AFM revision and repetitive replacement and inspections. This new AD removes airplanes from the applicability. This AD results from development of a terminating action. We are issuing this AD to ensure that the flightcrew has the procedures necessary to address failure of an MLG to extend following a gear-down selection; and to detect and correct such failure, which could result in a gear-up landing and possible injury to passengers and crew.

The FAA is adopting a new airworthiness directive (AD) for DORNIER LUFTFAHRT GmbH Model 228-212 airplanes. This AD requires you to inspect the landing gear carbon brake assembly. This AD results from mandatory continuing airworthiness information (MCAI) issued by the European Aviation Safety Agency (EASA), which is the airworthiness authority for the European Union. We are issuing this AD to inspect the landing gear carbon brake assembly to detect and replace loose bolts or self-locking nuts, which could result in the brake assembly detaching and malfunctioning, degrade brake performance and potentially cause loss of control of the aircraft during landing and roll-out.

The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 737-600, -700, -700C, -800, and -900 series airplanes. This AD requires testing the electrical resistance of the bond between the bulkhead fitting for the fuel feed line and the front spar of the left and right wings, inspecting an adjacent bonding jumper to make sure it is installed correctly, and performing corrective and other specified actions as applicable. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent arcing or sparking in the fuel tank in the event of a lightning strike, which could result in an uncontrolled fire or explosion.

The FAA proposes to supersede an existing airworthiness directive (AD) that applies to all Airbus Model A300 airplanes and Model A310 airplanes, and certain Airbus Model A300-600 series airplanes. The existing AD currently requires an inspection of the wing and center fuel tanks to determine if certain P- clips are installed and corrective action if necessary; an inspection of electrical bonding points of certain equipment in the center fuel tank for the presence of a blue coat and related investigative and corrective actions if necessary; and installation of new bonding leads and electrical bonding points on certain equipment in the wing, center, and trim fuel tanks, as necessary. This proposed AD would require, for certain airplanes, installation of bonding on an additional bracket. This proposed AD results from fuel system reviews conducted by the manufacturer. We are proposing this AD to ensure continuous electrical bonding protection of equipment in the wing, center, and trim fuel tanks and to prevent damage to wiring in the wing and center fuel tanks, due to failed P-clips used for retaining the wiring and pipes, which could result in a possible fuel ignition source in the fuel tanks.

This notice establishes Class E-2 airspace at Griffiss Airfield, Rome, NY. The opening of a tower and for the protection of instrument approaches make this action necessary. Controlled airspace extending upward from the surface to the base of the overlying controlled airspace is needed to contain aircraft executing an approach. The area would be depicted on aeronautical charts for pilot reference. This was published in the Federal Register on November 17, 2006. 71 FR 66894.
