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

This action amends the Class E airspace area at Lee's Summit Municipal Airport, Lee's Summit, MO. A review of the legal description revealed an incorrect coordinate describing the Airport Reference Point (ARP) for Lee's Summit Municipal Airport. This action corrects that error.

The FAA is proposing to amend the aircraft engine type certification standards by adding standards for pressurized engine static parts that are equivalent to those already adopted by European Aviation Safety Agency (EASA). The proposed rule would establish uniform standards for the certification of these parts in the United States and in Europe. U.S. manufacturers already meet the EASA requirements.

The FAA is superseding an existing airworthiness directive (AD), which applies to all Airbus Model A318-100, A319-100, A320-200, A321-100, and A321-200 series airplanes, and Model A320-111 airplanes. That AD currently requires an inspection to determine whether certain braking and steering control units (BSCUs) are installed or have ever been installed. For airplanes on which certain BSCUs are installed or have ever been installed, the existing AD requires an inspection of the nose landing gear (NLG) upper support, and corrective action if necessary; and a check of the NLG strut inflation pressure, and an adjustment if necessary. For some of these airplanes, the existing AD also requires a revision to the aircraft flight manual to incorporate an operating procedure to recover normal steering in the event of a steering failure. This new AD instead requires repetitive inspections of the NLG upper support, and related investigative/corrective actions in accordance with new service information; and removes the one-time inspection that was required by the existing AD. This new AD also provides an optional terminating action for the repetitive inspections. This AD results from a report of an incident where an airplane landed with the NLG turned 90 degrees from centerline, and from additional reports of NLG upper support anti-rotation lugs rupturing in service. We are issuing this AD to prevent landings with the NLG turned 90 degrees from centerline, which could result in reduced controllability of the airplane.

This Rule establishes, amends, suspends, or revokes Standard Instrument Approach Procedures (SIAPs) and associated Takeoff Minimums and Obstacle Departure Procedures for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, adding new obstacles, or changing air traffic requirements. These changes are designed to provide safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.

The FAA is superseding an existing airworthiness directive (AD), which applies to all Avions Marcel Dassault-Breguet Model Falcon 10 airplanes. That AD currently requires either revising the airplane flight manual (AFM) and installing a placard in the flight deck to prohibit flight into known or forecasted icing conditions, or repetitively inspecting for delamination of the flexible hoses in the wing (slat) anti-icing system and performing corrective actions if necessary. That AD also provides optional terminating action for the repetitive inspections. This new AD mandates the previously optional terminating action. This AD results from a report of in-service delamination of a flexible hose in the slat anti-icing system at a time earlier than previously reported. We are issuing this AD to prevent collapse of the flexible hoses in the slat anti-icing system, which could lead to insufficient anti-icing capability and, if icing is encountered in this situation, could result in reduced controllability of the airplane.

The Federal Aviation Administration (FAA) proposes to rule and invites public comment on the release of 2.43 acres of land at the Oceano Airport, Oceano, California, from all the conditions in the grant agreements under the provisions of Section 125 of the Wendell H. Ford Aviation Investment Reform Act for the 21st Century (AIR 21), now 49 U.S.C. 47107(h)(2). The land will be sold to the San Luis Obispo County Sanitation District and used for commercial purposes by the District for purposes compatible with the airport.

The FAA proposes to adopt a new airworthiness directive (AD) for Honeywell International Inc. (Honeywell) TFE731-2C, -3B, -3BR, -3C, -3CR, -3D, -3DR, -4R, -5AR, -5BR, -5R, -20R, -20AR, -20BR, -40, -40AR, -40R, and -60 series turbofan engines. This proposed AD would require removal from service of certain high pressure (HP) turbine rotor assemblies with part numbers (P/Ns) 3075772-1 and 3060841-1 using a drawdown schedule, and returning them to Honeywell for curvic root radius inspection. This proposed AD results from the manufacturer's report that some HP turbine rotor discs received improperly machined radii in the root of the forward and aft curvic teeth during manufacture. We are proposing this AD to prevent uncontained failure of the HP turbine rotor assembly and damage to the airplane.

The FAA is amending the certification standards for original and amended type certificates for aircraft engines by modifying the standards for engine life-limited parts. This final rule establishes new and uniform standards for the design and testing of life-limited parts for aircraft engines certificated by the FAA and the European Aviation Safety Agency (EASA). This rule retains the current lifing requirements, introduces damage tolerance requirements into the design process, and strengthens cooperation between engineering, manufacturing, and service elements of turbine engine manufacturers. These new requirements provide an added margin of safety and will reduce the number of life-limited parts failures due to material, manufacturing, and service induced anomalies. Additionally, this action adds new standards for the design of reciprocating engine turbocharger rotors.
