Federal Aviation Administration April 30, 2009 – Federal Register Recent Federal Regulation Documents

This action proposes to establish Class D airspace at Fort Worth Spinks Airport, Fort Worth, TX. Establishment of an air traffic control tower at Fort Worth Spinks Airport has made this action necessary for the safety and management of Instrument Flight Rules (IFR) aircraft operations at Fort Worth Spinks Airport.

The Federal Aviation Administration (FAA) announces its determination that the noise exposure maps submitted by the City of Los Angeles for Van Nuys Airport under the provisions of 49 U.S.C. 47501 et seq. (Aviation Safety and Noise Abatement Act) and 14 CFR Part 150 are in compliance with applicable requirements. The FAA also announces that it is reviewing a proposed noise compatibility program that was submitted for Van Nuys Airport under Part 150 in conjunction with the noise exposure map, and that this program will be approved or disapproved on or before October 16, 2009.

The FAA proposes to adopt a new airworthiness directive (AD) for IAE V2500-A1, V2527E-A5, V2527M-A5, V2528-D5, V2530-A5, and V2533- A5 turbofan engines. This proposed AD would require a onetime inspection of certain vortex reducers for cracks, and replacing the reducer and high-pressure (HP) compressor stage 3-8 drum if the reducer is cracked. This proposed AD results from reports of fractured vortex reducers found at shop visits. We are proposing this AD to inspect for cracks in the vortex reducer. Cracks in the vortex reducer could cause an uncontained failure of the HP compressor stage 3-8 drum, which could result in damage to the airplane.

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:

We are adopting a new airworthiness directive (AD) for certain Cessna Aircraft Company (Type Certificate previously held by Columbia Aircraft Manufacturing (previously The Lancair Company)) Models LC40- 550FG, LC41-550FG, and LC42-550FG airplanes. This AD requires you to repetitively inspect the rudder hinges and the rudder hinge brackets for damage, i.e., cracking, deformation, and discoloration. If damage is found during any inspection, this AD also requires you to replace the damaged rudder hinge and/or rudder hinge bracket. This AD results from reports that cracked lower rudder hinge brackets were found on two of the affected airplanes. We are issuing this AD to detect and correct damage in the rudder hinges and the rudder hinge brackets, which could result in failure of the rudder. This failure could lead to loss of control.

The FAA is superseding an existing airworthiness directive (AD), which applies to certain Airbus Model A318-100 and A319-100 series airplanes; A320-111 airplanes; A320-200 series airplanes; and A321-100 and A321-200 series airplanes. That AD currently requires a one-time inspection of the horizontal hinge pin of the 103VU electrical panel in the avionics compartment to determine if the hinge pin can move out of the hinge, and related investigative and corrective actions if necessary. This new AD instead requires installing a hinge pin stopper on the internal door of the 103VU electrical panel. This AD results from a report indicating that electrical wire damage was found in the 103VU electrical panel due to contact between the hinge pin and the adjacent electrical wire harness. We are issuing this AD to prevent contact between the horizontal hinge pin and the adjacent electrical wire harness, which could result in damage to electrical wires, and consequent arcing and/or failure of associated systems.
