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

The FAA is issuing this notice to advise the public of a the initial meeting of RTCA Special Committee 207, Airport Security Access Control Systems. The FAA is holding this meeting to provide interested individuals an opportunity to participate.

This amendment adopts a new airworthiness directive (AD) for the Agusta S.p.A. (Agusta) Model AB412 Series helicopters. This action requires inspecting each affected tail rotor blade (blade) forward tip weight retention block (tip block) and the aft tip closure (tip closure) for adhesive bond voids, and removing any blade with an excessive void from service. This AD also requires modifying certain blades by installing shear pins and tip closure rivets on all affected blades. This amendment is prompted by reports of in-flight loss of tip blocks and tip closures resulting in minor to substantial damage. The actions specified in this AD are intended to prevent loss of the tip block or tip closure, loss of a blade, and subsequent loss of control of the helicopter.

The FAA is adopting a new airworthiness directive (AD) for Turbomeca S.A. Arriel 2B turboshaft engines with Modification TU62A incorporated. This AD results from several reports of the hydromechanical unit (HMU) acceleration controller axle sticking. This AD requires initial and repetitive inspections, cleaning, lubrication, and checks for proper operation of the HMU acceleration controller axle. We are issuing this AD to prevent loss of control of engine fuel flow in manual control mode or mixed control mode, leading to engine overspeed and in-flight engine shutdown, or uncommanded in-flight engine shutdown.

The FAA is adopting a new airworthiness directive (AD) for all McDonnell Douglas Model MD-90-30 airplanes. This AD requires replacing existing dual anti-skid control manifolds (DACM) with new, improved or reworked and reidentified DACMs; inspecting the inlet filters and other components of the DACMs for damage; replacing any damaged DACM components with new or serviceable components; and flushing/cleaning the braking system prior to replacing the inlet filters. This AD is prompted by reports of multiple incidents of blown tires on landing while using maximum autobrake. We are issuing this AD to prevent metallic fibers from the first stage filter of the servo valves inside the DACM from becoming lodged in the first stage nozzle of the servo valve, which could lead to tire failure during high speed/high energy braking and possible subsequent runway departure.

The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 747-400, -400D, -400F; 767-200, -300, -300F; and 777-200 and -300 series airplanes. This AD requires installing a jumper wire between the wiring of the fire extinguisher switch and the fuel shutoff switch for each engine, and other specified actions. This AD is prompted by a certain combination of conditions, which could cause the fuel spar shutoff valves to remain partially open. We are issuing this AD to prevent a latent open circuit that could leave the fuel spar shutoff valve in a partially open position when the engine fire switch is activated, which could result in fuel from the engine feeding an uncontrolled fire in the engine or the strut.

The FAA is adopting a new airworthiness directive (AD) for all AvCraft Dornier Model 328-100 airplanes. This AD requires modifying the electrical wiring of the fuel pumps; installing insulation at the hand flow control and shut-off valves, and other components of the environmental control system; and installing markings at fuel wiring harnesses. This AD also requires revising the Airworthiness Limitations section of the Instructions for Continued Airworthiness to incorporate new inspections of the fuel tank system. This AD is prompted by the results of fuel system reviews conducted by the airplane manufacturer. We are issuing this AD to reduce the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.

The FAA proposes to supersede an existing airworthiness directive (AD) for Turbomeca Artouste III series turboshaft engines. That AD currently requires smoke emission checks after every ground engine shutdown, and if necessary, additional checks and possibly removing the engine from service. That action also requires inspection of central labyrinths not previously inspected, or not replaced after the engine logged 1,500 operating hours, and, replacement if necessary. That action also requires the removal of injection wheels at a new lower life limit. This proposed AD includes the same requirements as the existing AD, but reduces the compliance time for the initial inspection of the central labyrinth and adds repetitive inspections of the central labyrinth. This proposed AD results from reports and analyses of in-flight engine shutdowns occurring since we issued AD 2002-22-11. We are proposing this AD to prevent injection wheel cracks and excessive central labyrinth wear, which could result in an in- flight engine shutdown.

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 notice proposes to create a Class E surface area at Storm Lake, IA. It also proposes to modify the Class E5 airspace at Storm Lake, IA.

The Federal Aviation Administration (FAA) announces its findings on the noise compatibility program submitted by the city of Georgetown under the provisions of 49 U.S.C. (the Aviation Safety and Noise Abatement Act, hereinafter referred to as ``the Act'') and 14 CFR Part 150. These findings are made in recognition of the description of Federal and nonfederal responsibilities in Senate Report No. 96-52 (1980). On January 26, 2004, the FAA determined that the noise exposure maps submitted by the city of Georgetown under Part 150 were in compliance with applicable requirements. On May 27, 2005, the FAA approved the Georgetown Municipal Airport noise compatibility program. Most of the recommendations of the program were approved.

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 sale of the airport property. The proposal consists of a parcel of land totaling approximately 5.76 acres. Current use and present condition is vacant grassland. The parcel is hilly and partially wooded. The land was acquired under FAA Project No. 9-20-072-6001. There are no impacts to the airport by allowing the airport to dispose of the property. The proposal concerns selling the land to the Michigan Department of Transportation to provide a right-of-way for the proposed Interstate-96 interchange with 36th Street. The project will improve traffic flow to areas along the northern boundary of the airport. 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 disposal 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 proposes to rule and invites public comment on the release of land at Snohomish County Airport/Paine Field under the provisions of Section 125 of the Wendell H. Ford Aviation Investment Reform Act for the 21st Century (AIR 21).

This action establishes a low altitude area navigation (RNAV) route T-270 in Alaska to support the Alaskan Capstone Program. The FAA is taking this action to enhance safety and improve the efficient use of the navigable airspace in Alaska.

These special conditions are issued to Duncan Aviation Inc., 15745 S Airport Rd Battle Creek, MI 49015, for a Supplemental Type Certificate for the Raytheon 300 King Air. This airplane will have novel and unusual design features when compared to the state of technology envisaged in the applicable airworthiness standards. These novel and unusual design features include the installation of an electronic flight instrument system (EFIS). The EFIS consists of the Universal Avionics, Inc. EFI-890R system for which the applicable regulations do not contain adequate or appropriate airworthiness standards for the protection of these systems from the effects of high intensity radiated fields (HIRF). The installation includes three EFI- 890R Flat Panel Displays (two Primary Flight Displays Pilot/Copilot and one Navigational Displays Pilot), and supporting equipment. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to the airworthiness standards applicable to these airplanes.

This document revises an earlier proposed airworthiness directive (AD), applicable to certain EMBRAER Model EMB-135BJ and EMB- 145XR series airplanes, that would have required installation of an additional indication device to the clear-ice indication system. This new action revises the proposed rule by changing the description of the unsafe condition, and by adding instructions for modifying certain existing circuits, replacing an existing indicator lamp with a new, improved lamp, and performing other required corrections/modifications. The actions specified by this new proposed AD are intended to prevent undetected build-up of clear ice on the wing surfaces, which could lead to reduced controllability of the airplane. This action is intended to address the identified unsafe condition.

The FAA proposes to supersede an existing airworthiness directive (AD) that applies to certain Bombardier Model CL-215-1A10 (Water Bomber), CL-215-6B11 (CL215T Variant), and CL-215-6B11 (CL415 Variant) series airplanes. The existing AD currently requires repetitive ultrasonic inspections to detect cracking of the lower caps of the wing front spar and rear spar, and corrective action if necessary. This proposed AD would reduce the threshold to do the initial inspections and revise the repetitive inspection interval. This proposed AD also adds a repetitive ultrasonic inspection of the wing lower skin. This proposed AD is prompted by reports of cracks in the front and rear spar lower caps. We are proposing this AD to detect and correct cracking of the lower caps of the wing front spar and rear spar, which could result in reduced structural integrity of the airplane.

The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Model A300-600 and A310 series airplanes. This proposed AD would require inspecting for certain serial numbers on elevators, and doing a detailed inspection, visual inspection with a low-angle light, and tap-test inspection of the upper and lower surfaces of the external skins on certain identified elevators for any damage (i.e., debonding of the graphite fiber reinforced plastic/Tedlar film protection, bulges, debonding of the honeycomb core to the carbon fiber reinforced plastic, abnormal surface reflections, and torn-out plies), and corrective actions if necessary. This proposed AD is prompted by reports of debonded skins on the elevators. We are proposing this AD to detect and correct debonding of the skins on the elevators, which could cause reduced structural integrity of an elevator and reduced controllability of the airplane.

The FAA proposes to supersede an existing airworthiness directive (AD) that applies to all Bombardier Model CL-600-2B19 series airplanes. The existing 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 proposed AD would revise the Airworthiness Limitations section of the Instructions of Continued Airworthiness to incorporate certain repetitive tasks for the aileron control system and would require a briefing to advise flight crews 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 proposed AD is prompted by the development of terminating actions for the AFM revisions. We are proposing this AD to prevent aileron control stiffness during flight, which could result in reduced or possible loss of controllability of the airplane.

This notice announces the Office of Management and Budget's (OMB) approval of the information collection requirement in the final rule published on June 29, 2004 (FR 69 39292). This notice also provides the amendment numbers for the final rule that were absent when it was published.

The FAA adopts an airworthiness directive to supersede AD 93- 24-14 applicable to all The New Piper Aircraft, Inc. (Piper) PA-34 series airplanes. This AD results from many service difficulty reports related to the collapse of the nose landing gear (NLG). Consequently, this AD retains the actions required in AD 93-24-14, requires you to inspect the NLG and components of the NLG using new procedures for rigging the nose gear installation, and requires you to replace unserviceable parts. We are issuing this AD to detect, correct, and prevent failure in certain components of the NLG, lack of cleanliness of the NLG due to inadequate maintenance, or lack of lubricant in the NLG or NLG components. This failure of the NLG could lead to loss of control of the airplane during take-off, landing, or taxiing operations.

The FAA is superseding an existing airworthiness directive (AD) for Hoffmann Propeller GmbH & Co KG Models HO-V343 and HO-V343K propellers. That AD currently requires initial and repetitive visual inspections of propeller blades for blade shake and blade nut preload. That AD also requires initial and repetitive eddy current inspections of blade hubs for damage and cracks. This AD requires an ultrasonic inspection of the propeller hub and an eddy current inspection of the propeller hub if any cracks are discovered during ultrasonic inspection. Additionally, this AD requires sending a hub inspection report to the manufacturer. This AD also requires replacement of the propeller if any signs of blade shake, cracks, or other damage to the propeller hub outside serviceable limits are detected during the inspections. This AD results from the discovery of a propeller blade separation due to a possible hub failure. We are issuing this AD to prevent propeller hub failure and blade separation due to an unknown root cause, leading to damage and possible loss of control of the airplane.

The FAA is adopting a new airworthiness directive (AD) for all BAE Systems (Operations) Limited (Jetstream) Model 4101 airplanes. This AD requires the overhaul of certain auxiliary components installed on the main landing gear (MLG) and nose landing gear (NLG). This AD is prompted by manufacturer determination that overhaul limits need to be imposed for certain auxiliary components of the MLG and NLG. Components that exceed the established overhaul limits could fail due to fatigue, wear, and age. We are issuing this AD to prevent failure of the MLG or NLG, and consequent damage to the airplane and injury to flightcrew and passengers.

The Federal Aviation Administration published a document in the Federal Register on June 3, 2005, concerning Technical Standard Order (TSO) C-122a, Equipment That Prevent Blocked Channels Used in Two-Way Radio Communications Due to Simultaneous Transmissions. The document contains an incorrect Internet address for the retrieval of the TSO.

The Federal Aviation Administration published a document in the Federal Register on June 3, 2005, concerning Technical Standard Order (TSO) C-128a, Equipment That Prevent Blocked Channels Used in Two-way Radio Communications Due to Unintentional Transmissions. The document contains an incorrect Internet address for the retrieval of the TSO.

The FAA is adopting a new airworthiness directive (AD) for Honeywell International Inc. (formerly AlliedSignal Inc. and Garrett Turbine Engine Co.) TFE731-2 and -3 series turbofan engines with certain part numbers (P/Ns) and serial numbers (SNs) of low pressure (LP) 1st and 2nd stage turbine rotor discs initially installed. This AD requires replacement of those LP 1st and 2nd stage turbine rotor discs. This AD results from a report of an uncontained failure of an LP 2nd stage turbine rotor disc that resulted in an in-flight engine shutdown. We are issuing this AD to prevent LP turbine rotor disk separation, which could result in an uncontained engine failure and damage to the airplane.
