Federal Aviation Administration September 2005 – Federal Register Recent Federal Regulation Documents

This document publishes in the Federal Register an amendment adopting airworthiness directive (AD) 2005-18-51 that was sent previously to all known U.S. owners and operators of Boeing Model 777 airplanes by individual notices. This AD supersedes an existing AD that applies to certain Boeing Model 777-200 and ``300 series airplanes. The existing AD currently requires modification of the operational program software (OPS) of the air data inertial reference unit (ADIRU). This new AD requires installing a certain OPS in the ADIRU, and revising the airplane flight manual to provide the flightcrew with operating instructions for possible ADIRU heading errors and for potential incorrect display of drift angle. This AD results from a recent report of a significant nose-up pitch event. We are issuing this AD to prevent the OPS from using data from faulted (failed) sensors, which could result in anomalies of the fly-by-wire primary flight control, autopilot, auto-throttle, pilot display, and auto-brake systems. These anomalies could result in high pilot workload, deviation from the intended flight path, and possible loss of control of the airplane.

The FAA is superseding an existing airworthiness directive (AD) that applies to all Dassault Model Falcon 10 series airplanes. The existing AD currently requires revising the airplane flight manual (AFM) and installing a placard in the flight deck to prohibit flight into known or forecasted icing conditions. In lieu of the AFM revision and placard installation, that AD allows identifying the part number of each flexible hose in the wing (slat) anti-icing system, performing repetitive inspections of each hose for delamination, and performing corrective actions if necessary. This AD adds the following actions (also in lieu of the AFM revision and placard installation): New repetitive inspections for delamination at reduced intervals, corrective actions if necessary, and an additional AFM revision to include a statement to track flight cycles when the slat anti-icing system is activated. This AD also provides an option to repetitively replace the existing flexible hoses with improved flexible hoses, which terminates the repetitive inspection requirements. 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) is issuing this Notice of Availability to advise the public that a Draft Environmental Impact Statement (DEIS) containing a DOT Section 4(f)/303(c) evaluation will be available for public review beginning September 9, 2005. The DEIS details the proposed development of a replacement airport and related facilities for the city of St. George, Utah and addresses the environmental impacts associated with its development. The DEIS presents the purpose and need for the proposed project, a comprehensive analysis of the alternatives to the proposed project, and potential environmental impacts associated with the proposed development of the proposed replacement airport. The City of St. George, operator of the existing St. George Municipal Airport, has submitted an Airport Layout Plan, as revised, for approval. The DEIS assesses the potential impacts that may result from the development of a replacement airport with a 9,3000-foot Runway 01/19 and all support facilities (i.e., taxiways and associated lighting and NAVAIDS). This DEIS also assesses the federal action regarding installation of navigational aids, airspace use, approach and departure procedures, and associated terminal and landside projects. One historic site, the Little Black Mountain Petroglyph site, would potentially be affected. This document also assesses the potential noise impact on Zion National Park, Little Black Mountain Petroglyph site, and 42 other potentially noise sensitive properties in the vicinity. Public Comment and Information Meeting/Public Hearing: The public comment period on the DEIS and associated studies will start September 9, 2005 and will end on November 8, 2005. A Public Information Meeting and Public Hearing will be held on October 19, 2005 at The Dixie Center, 1835 Convention Center Drive, St. George, UT 84790. The Public Information Meeting will begin at 3 p.m. (MST) and will last until 7 p.m. (MST). The Public Hearing will be conducted concurrently with an information workshop. The public will be afforded the opportunity to present oral testimony and/or written testimony pertinent to the subject of the hearing. Testimony from an elected official, group or agency representative will be limited to 5 minutes. All others will be given 3 minutes.

The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 757-200 and -300 series airplanes and Model 767 series airplanes. This AD requires replacing the existing operational software of the Pegasus flight management computer (FMC) system with new, improved operational software. This AD results from reports of ``old'' or expired air traffic control (ATC) clearance messages being displayed on the control display unit (CDU) of the FMC system during subsequent flights. We are issuing this AD to prevent display of ``old'' or expired ATC clearance messages on the CDU of subsequent flights, which could result in the airplane entering unauthorized airspace or following a flight path that does not provide minimum separation requirements between aircraft, and a consequent near miss or a mid-air collision.

The FAA is adopting a new airworthiness directive (AD) for all Israel Aircraft Industries, Ltd., Model 1124 and 1124A airplanes. This AD requires a one-time inspection for chafing of the electrical bundles in the overhead circuit breaker panel, and for adequate clearance between the fuselage frame and adjacent structures; and repair and rework if necessary. This AD results from reports of fire and smoke occurring in the passenger cabin. This AD also requires certain preventive actions. We are issuing this AD to prevent chafing of the electrical bundles in the overhead circuit breaker panel, which could result in a short circuit and consequent fire and smoke in the airplane.

The FAA proposes to adopt a new airworthiness directive (AD) for all BAE Systems (Operations) Limited (Jetstream) Model 4101 airplanes. This proposed AD would require modifying the wiring of the starter-generator terminal block. This proposed AD results from a report of total electrical failure just as the airplane landed. We are proposing this AD to prevent total electrical failure and consequent reduced controllability of the airplane.

The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 747-400 series airplanes. This proposed AD would require doing a conductivity test of the upper deck floor beam at station 400 to identify the floor beam material. If the floor beam is manufactured from 7050 aluminum alloy, this proposed AD would also require inspecting the upper deck floor beam and certain fastener holes at the floor beam upper chord for cracking; repairing any cracking if necessary; and doing a preventative modification. This proposed AD results from several reports indicating that fatigue cracking was found in upper deck floor beams made from 7050 aluminum alloy. We are proposing this AD to find and fix cracking in the upper deck floor beam, which could extend and sever the floor beam. A severed floor beam could result in loss of controllability and rapid decompression of the airplane.

This document establishes Class D airspace at Eau Clair, WI. A control tower is currently under construction at Chippewa Valley Regional Airport. Controlled airspace extending upward from the surface is required when the control tower is operational. This action establishes a radius of controlled airspace for Eau Clair, WI.

This document confirms the effective date of the direct final rule which revises Class E airspace at Abilene Municipal Airport, KS.

The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 737-100, -200, -200C, and -300 series airplanes. This AD requires repetitive detailed inspections to detect discrepancies of the retaining pin lugs on the support fitting of the main landing gear (MLG) beam, and rework of the support fitting, or replacement of the fitting if necessary. This AD is prompted by reports of discrepancies of the lugs. We are issuing this AD to prevent separation of the support beam of the MLG from the rear spar, which could cause cracking of the MLG support fitting and a consequent leak in the wing fuel tank or collapse of the MLG.

This amendment establishes, amends, suspends, or revokes Standard Instrument Approach Procedures (SIAPs) and/or Weather Takeoff Minimums 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, addition of new obstacles, or changes in 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.

This action modifies Federal Airway V-536 by adding a route from the Great Falls, MT, Very High Frequency Omnidirectional Range/ Tactical Air Navigation (VORTAC) to the SWEDD intersection. The purpose of this airway segment is to enhance the management of aircraft transiting between Great Falls, MT, and Bozeman, MT.

The FAA proposes to adopt a new airworthiness directive (AD) for certain Saab Model SAAB 2000 airplanes. This proposed AD would require modifying the manual feather-and-unfeather system for the propellers to make the design of the system more robust. This proposed AD results from reports of in-flight engine shutdown caused by uncommanded operation of the feather pump of the propeller. We are proposing this AD to prevent uncommanded feathering of the propeller, which could result in the shutdown of an engine during flight and consequent reduced controllability of the airplane.

The FAA proposes to adopt a new airworthiness directive (AD) for certain McDonnell Douglas transport category airplanes. This proposed AD would require an inspection to determine the part number of the upper and lower stop pad support fittings of all the lower cargo doors, repetitive inspections of all early configuration stop pad support fittings, and corrective action if necessary. This proposed AD would also provide an optional terminating action for the repetitive inspections. This proposed AD is prompted by a report of cracks found in the area of the upper and lower stop pad support fittings of the cargo door pan on numerous airplanes. We are proposing this AD to prevent cracks in the cargo door pan, which could result in the inability to fully pressurize an airplane and possible rapid decompression of the airplane.

The National Park Service (NPS) and the Federal Aviation Administration (FAA), as required by the National Parks Air Tour Management Act of 2000, established the National Parks Overflights Advisory Group (NPOAG) in March 2001. The NPOAG was formed to provide continuing advice and counsel with respect to commercial air tour operations over and near national parks. On October 10, 2003, the Administrator signed Order No. 1110-138 establishing the NPOAG as an aviation rulemaking committee (ARC). This notice informs the public of a vacancy on the NPOAG ARC, for a member representing air Indian tribal interests, and invites interested persons to apply to fill the vacancy.

The Federal Aviation Administration (FAA) is considering a proposal to change a portion of the airport from aeronautical use to non-aeronautical use and to authorize the lease of the airport property. The proposal consists of two (2) parcels of land totaling approximately 68 acres. Current use and present condition is vacant grassland with intermittent wetland areas. The land is currently zoned residential. Parcel 15A was acquired under FAA Project No. 8-26-0051-02. Parcel 62 was not acquired with federal funds. There are no impacts to the airport by allowing the airport to lease the property.The airport desires to enter into a long- term lease to provide a long-term revenue source. Approval does not constitute a commitment by the FAA to financially assist in the disposal of the subject airport property nor a determination of eligibility for grant-in-aid funding from the FAA. The disposition of proceeds from the lease of the airport property will be in accordance FAA's Policy and Procedures Concerning the Use of Airport Revenue, published in the Federal Register on February 16, 1999. In accordance with section 47107(h) of title 49, United States Code, this notice is required to be published in the Federal Register 30 days before modifying the land-use assurance that requires the property to be used for an aeronautical purpose.

The FAA is superseding an existing airworthiness directive (AD), which applies to all Bombardier Model CL-600-2B19 series airplanes. That AD currently requires revising the airplane flight manual (AFM) to provide the flightcrew with operating limitations and procedures to enable them to maintain controllability of the airplane in the event that aileron control stiffness is encountered during flight. This new AD requires revising the Airworthiness Limitations section of the Instructions of Continued Airworthiness to incorporate certain repetitive tasks for the aileron control system and requires a briefing to advise flightcrews that certain aileron control checks are no longer required. After accomplishing the applicable initial tasks, the existing AFM revisions for the aileron control check may be removed from the AFM. This AD results from the development of terminating actions for the AFM revisions. We are issuing this AD to prevent aileron control stiffness during flight, which could result in reduced or possible loss of controllability of the airplane.

The FAA is superseding an existing airworthiness directive (AD) for Pratt & Whitney (PW) JT8D-209, -217, -217A, -217C, and -219 turbofan engines. That AD currently requires revisions to the engine manufacturer's time limits section (TLS) to include enhanced inspection of selected critical life-limited parts at each piece-part opportunity. This AD requires modifying the airworthiness limitations section of the manufacturer's manual and an air carrier's approved continuous airworthiness maintenance program to incorporate additional inspection requirements. An FAA study of in-service events involving uncontained failures of critical rotating engine parts has indicated the need for mandatory inspections. The mandatory inspections are needed to identify those critical rotating parts with conditions, which if allowed to continue in service, could result in uncontained failures. We are issuing this AD to prevent critical life-limited rotating engine part failure, which could result in an uncontained engine failure and damage to the airplane.

The FAA adopts a new airworthiness directive (AD) for certain Cirrus Design Corporation (CDC) Models SR20 and SR22 airplanes. This AD requires you to measure and adjust the crew seat break-over bolts and to replace the crew seat recline locks on both crew seats. This AD results from CDC discovering that the crew seats, under emergency landing dynamic loads, may fold forward at less than the 26 g required by the regulations. We are issuing this AD to prevent the crew seats from folding forward during emergency landing dynamic loads with consequent occupant injury.
