Federal Aviation Administration March 27, 2006 – Federal Register Recent Federal Regulation Documents

The FAA proposes to supersede an existing airworthiness directive (AD) that applies to certain BAE Systems (Operations) Limited Model BAe 146 and Avro 146-RJ airplanes. The existing AD currently requires a one-time inspection to detect corrosion of the flap structure and machined ribs, corrective actions if necessary, and reprotection of the rib boss bores. This proposed AD would require a records review of the results of that inspection, and an additional inspection and related investigative/corrective action if necessary. This proposed AD results from the development of an improved inspection for corrosion in the subject area. We are proposing this AD to detect and correct corrosion in the flap structure and machined ribs, which could result in reduced structural integrity of the airplane.

The FAA is revising an earlier NPRM for an airworthiness directive (AD) that would have applied to certain Airbus Model A330- 200, A330-300, A340-200, and A340-300 series airplanes, and A340-541 and A340-642 airplanes. The original NPRM would have required inspecting to determine if certain emergency escape slides/slide rafts (referred to as slide/rafts) are installed in certain crew/ passenger doors; and, if so, performing a one-time inspection to determine if the electrical harnesses of the slide/rafts are properly routed, and rerouting the harnesses if necessary. The original NPRM resulted from a report that a slide/raft failed to deploy properly during a deployment test. This action revises the original NPRM by expanding the applicability of the proposed AD. We are proposing this AD to detect and correct improper routing of the electrical harnesses of certain slide/rafts, which could prevent proper deployment of the slide/rafts and delay evacuation of passengers and flightcrew during an emergency.

The FAA is revising an earlier supplemental NPRM for an airworthiness directive (AD) that applies to certain Airbus airplanes as listed above. The first supplemental NPRM would have required repetitively inspecting for cracking in the web of nose rib 7 of the inner flap on the wings, and performing related investigative/ corrective actions if necessary. The original NPRM resulted from reports of cracking in the web of nose rib 7 of the inner flap. This action revises the first supplemental NPRM by requiring eventual replacement of nose rib 7 with a new, improved rib, which would terminate the proposed inspections. This action also removes from the applicability airplanes on which the improved nose rib 7 was installed during production. We are proposing this supplemental NPRM to prevent cracking in the web of nose rib 7, which could result in rupture of the attachment fitting between the inner flap and flap track 2, and consequent reduced structural integrity of the flap.

The FAA is revising an earlier NPRM for an airworthiness directive (AD) that applies to all Bombardier Model DHC-7 airplanes. The original NPRM would have required implementing a corrosion prevention and control program (CPCP) either by accomplishing specific tasks or by revising the maintenance inspection program to include a CPCP. The original NPRM resulted from a determination that, as airplanes age, they are more likely to exhibit indications of corrosion. This action revises the original NPRM by clarifying certain compliance aspects of the proposed AD that were not adequately defined in the original NPRM. We are proposing this supplemental NPRM to prevent structural failure of the airplane due to corrosion.

The Federal Aviation Administration (FAA) has revised its procedures for implementing the National Environmental Policy Act by revising Order 1050.1E, Environmental Impacts: Policies and Procedures, with Order 1050.1E, Change 1. The revisions include: changes for clarification, consistency, and addition of information; corrections; and editorial changes. This notice informs the public of the availability of the Final Order. This notice also provides the public with information on how to access Order 1050.1E, Change 1 on FAA's Office of Environment and Energy Web site.

This action establishes a RITTR, designated T-210, in the Jacksonville, FL, terminal area. The purpose of this route is to expedite the handling of Instrument Flight Rules (IFR) overflight aircraft transitioning through busy terminal airspace. The FAA is taking this action to enhance the safe and efficient use of the navigable airspace in the Jacksonville, FL, terminal area.

This document identifies and provides guidance on the current FAA policies regarding requests for an exemption from the rules governing the operation of aircraft for the purpose of carrying passengers on living history flights in return for compensation. Specifically, this document clarifies which aircraft are potentially eligible for an exemption and what type of information petitioners should submit to the FAA for proper consideration of relief from the applicable regulations. This policy does not apply to flight crew training or commercial space transportation issues.

The Federal Aviation Administration (FAA) is issuing this notice to advise the public of the approval of a Finding of No Significant Impact (FONSI) on an Environmental Assessment for proposed Federal actions at Southern Illinois Airport, Carbondale-Murphysboro, Illinois. The FONSI specifies that the proposed federal actions and local development projects are consistent with existing environmental policies and objectives as set forth in the National Environmental Policy Act of 1969 and will not significantly affect the quality of the environment. A description of the proposed Federal actions is: (a) To issue an environmental finding to allow approval of the Airport Layout Plan (ALP) for the development items listed below; (b) Approval of the Airport Layout Plan (ALP) for the development items listed below; and (c) Establish eligibility of the Southern Illinois Airport Authority to compete for Federal funding for the development projects depicted on the Airport Layout Plan. The specific items in the local airport development project include: Acquisition of approximately 210 acres of land in fee simple title including relocation assistance for one (1) residence; Widening of the existing Runway 18R/36L by 15 feet and construction of a 500- foot extension to Runway 36L to provide a total runway dimension of 4,000 feet x 75 feet. This action includes all appropriate grading and drainage; Extension and widening of the existing parallel taxiway to Runway 18R/36L to serve the extended runway threshold; Construction of new airport facilities in the western and northwestern airfield quadrants. This action includes the construction of a new west side entrance roadway system; creation of a new GPS non-precision Standard Instrument Approach Procedures (SIAP) for Runways 18R, 36L, and 36; relocation of portions of Airport Road, Fox Farm Road and the Airport Entrance Road to allow for the initiation of new non-precision instrument approach procedures for Runways 36L and 36R; relocation of a portion of Fox Farm Road to remove the facility from within the Runway Protection Zone (RPZ) for Runway 06; relocation of the existing Visual Approach Descent Indicator (VADI) lights and associated wind cone to serve the relocated Runway 36L threshold; installation of Medium Intensity Runway Lights (MIRL) on the extended and widened runway; installation of Medium Intensity Taxiway Lights (MITL) on the extended on widened taxiway; relocation of a portion of the Southern Illinois Power Company's electric lines to allow for the new SIAPs to Runways 36L and 36; removal of obstructions in the approaches to Runways 06 and 18L; mitigation of impacts to 2.7 acres of wetlands; and the approval of the Southern Illinois ALP.

The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A318-100 series airplanes; Model A319-100 series airplanes; Model A320-111 airplanes; Model A320-200 series airplanes; Model A321-100 series airplanes; and Model A321-200 series airplanes. This AD requires replacing the water drain valves in the forward and aft cargo doors with new valves. This AD results from a report indicating that, during a test of the fire extinguishing system, air leakage through the water drain valves in the forward and aft cargo doors reduced the concentration of fire extinguishing agent to below the level required to suppress a fire. We are issuing this AD to prevent air leakage through the water drain valves, which, in the event of a fire in the forward or aft cargo compartment, could result in an insufficient concentration of fire extinguishing agent and consequent inability of the fire extinguishing system to suppress the fire.

The FAA is adopting a new airworthiness directive (AD) for 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. This AD requires operators to review the airplane's maintenance records to determine the part numbers of the magnetic fuel level indicators (MFLI) of the wing fuel tanks, and related investigative and corrective actions if necessary. This AD results from several in-service incidents of wear and detachment of the top-stops from the MFLI. Such detachment allows the top-stop to move around the wing fuel tank, and the top-stop could come into contact or in close proximity with a gauging probe, resulting in compromise of the air gap between the probe and the structure and creating a potential ignition source. We are issuing this AD to prevent an ignition source in the wing fuel tank in the event of a lightning strike, which could result in a fire or explosion.
