Federal Aviation Administration April 5, 2007 – Federal Register Recent Federal Regulation Documents

The FAA proposes to supersede an existing airworthiness directive (AD) that applies to all Airbus Model A318-100, A319-100, A320-200, A321-100, and A321-200 series airplanes, and Model A320-111 airplanes. The existing 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 proposed AD would require repetitive inspections of the NLG upper support, and related investigative/corrective actions in accordance with new service information; and would remove the one-time inspection that was required by the existing AD. This proposed AD also would provide an optional terminating action for the repetitive inspections. This proposed 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 proposing this AD to prevent landings with the NLG turned 90 degrees from centerline, which could result in reduced controllability of the airplane.

This technical amendment corrects a final rule published in the Federal Register on August 11, 2006 (71 FR 46076), Docket No. FAA- 2006-25153, Airspace Docket No. 06-AWP-10. In that rule, the reference to FAA Order 7400.9 was published as FAA Order 7400.9N. The correct reference is FAA Order 7400.9P. Also, the corresponding dates that refer to the Order should state ``* * * September 1, 2006, and effective September 15, 2006 * * *'', instead of ``* * * September 1, 2005, and effective September 15, 2005''. This technical amendment corrects those errors.

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:

The FAA is adopting a new airworthiness directive (AD) for all Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-135BJ airplanes. This AD requires modifying the forward and aft auxiliary fuel tanks. This AD results from a fuel system reassessment according to SFAR 88 criteria, which revealed the possibility of sparks due to chafing between the harnesses of the forward and aft auxiliary fuel tanks, between certain harnesses attached to the aircraft structure, or between certain harnesses attached to certain mechanical components. We are issuing this AD to prevent a potential ignition source inside a fuel tank, which, in combination with flammable fuel vapors, could result in a fuel tank explosion.

This action prohibits flight operations below flight level 200 within the territory and airspace of Somalia by all: (1) U.S. air carriers; (2) U.S. commercial operators; (3) operators of U.S. registered aircraft except when such operators are foreign air carriers; and (4) persons exercising the privileges of a U.S. airman certificate except if the flight is on behalf of a foreign air carrier. The FAA finds this action necessary to prevent a potential hazard to persons and aircraft engaged in such flight operations.

The Federal Aviation Administration is requesting public comment on Boca Raton Airport Authority's (BRAA) request to change +/- 4.67 acres of airport property from aeronautical use to non- aeronautical use. The parcel in question is the last remaining parcel of aeronautical land available at the Boca Raton Airport. The property in question is on the east side of Airport Road and approximately 1 mile north of Glades Road between the Premiere leasehold and the Fairfield Inn leasehold. The BRAA intends to use the property to develop an office building and possible restaurant(s). Portions of the building would house BRAA office, while the remainder would be leased to third party tenants for revenue generation. Documents reflecting the Sponsor's request are available, by appointment only, for inspection at the Airport Manager's office and the FAA Airport District Office.
