Federal Aviation Administration August 2010 – Federal Register Recent Federal Regulation Documents

The FAA has made available the final EA and FONSI/ROD for the proposed relocation of the Bowman County Airport. The EA was prepared in accordance with the National Environmental Policy Act (NEPA) of 1969, as amended, FAA Orders 1050.1E, ``Environmental Impacts: Policies and Procedures'' and FAA Order 5050.4B, ``NEPA Implementing Instructions for Airport Actions.''

We propose to adopt a new airworthiness directive (AD) for certain Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This proposed AD would require installing two warning level indicator lights on the P2-2 center instrument panel in the flight compartment for certain airplanes. For a certain other airplane, this proposed AD would require activating the cabin altitude warning and takeoff configuration warning lights. For all airplanes, this proposed AD also would require revising the airplane flight manual to remove certain requirements included by previous AD actions, to require new pressure altitude limitations for certain airplanes, and to advise the flightcrew of the following changes: revised emergency procedures to use when a cabin altitude warning or rapid depressurization occurs, and revised cabin pressurization procedures for normal operations. This proposed AD results from a design change in the cabin altitude warning

We propose to adopt a new airworthiness directive (AD) for the specified Eurocopter France model helicopters. This proposed AD would require replacing the aluminum tail rotor (T/R) blade pitch control shaft with a steel T/R blade pitch control shaft. This proposed AD is prompted by an incident involving a Eurocopter France Model AS-365N2 helicopter on which there was a loss of control of the T/R due to a broken shaft. The actions specified by this proposed AD are intended to prevent failure of the T/R blade pitch control shaft, loss of T/R control, and subsequent loss of control of the helicopter.

We propose to adopt a new airworthiness directive (AD) for the specified ECF model helicopters. This proposed AD results from a mandatory continuing airworthiness information (MCAI) AD issued by the European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community. The MCAI AD states that a dormant failure of one of the two contactors 53Ka or 53Kb can occur following certain modifications. Failure of a contactor can prevent switching from ``IDLE'' mode to ``FLIGHT'' mode during autorotation training making it impossible to execute a power recovery and compelling the pilot to continue the autorotation to the ground. This condition, if not corrected, can lead to an unintended touchdown to the ground during a practice autorotation at a flight-idle power setting, damage to the helicopter, and injury to the occupants.

This action amends Class E Airspace at Pine Mountain, GA, to accommodate the Standard Instrument Approach Procedures (SIAPs) developed for Harris County Airport.

We propose to adopt a new airworthiness directive (AD) for certain Model 737-900ER series airplanes. This proposed AD would require doing a one-time general visual inspection for a keyway in two fuel tank access door cutouts, and related investigative and corrective actions if necessary. This proposed AD results from reports of cracks emanating from the keyway of the fuel tank access hole. We are proposing this AD to detect and correct such cracking, which could result in the loss of the lower wing skin load path and consequent structural failure of the wing.

The Federal Aviation Administration (FAA) announces its determination that the noise exposure maps for T.F.Green Airport as submitted by the Rhode Island Airport Corporation under the provisions of Title I of the Aviation Safety and Noise Abatement Act of 1979 (Pub. L. 96-193) and 14 CFR part 150, are in compliance with applicable requirements.

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:

This notice contains a summary of a petition seeking relief from specified requirements of 14 CFR. The purpose of this notice is to improve the public's awareness of, and participation in, this aspect of FAA's regulatory activities. Neither publication of this notice nor the inclusion or omission of information in the summary is intended to affect the legal status of the petition or its final disposition.

This action amends the legal description of the VHF Omnidirectional Range (VOR) Federal Airways V-8, V-14, V-38, V-47, V- 279, and V-422 in the vicinity of Findlay, OH. The FAA is taking this action because the Findlay VHF Omnidirectional Range/Tactical Air Navigation (VORTAC), included as part of the V-8, V-14, V-38, V-47, V- 279, and V-422 route structure, is being renamed the Flag City VORTAC.

The FAA proposes to supersede an existing airworthiness directive (AD) that applies to certain Model DC-9-14 and DC-9-15 airplanes; and Model DC-9-20, DC-9-30, DC-9-40, and DC-9-50 series airplanes. The existing AD currently requires repetitive high frequency eddy current inspections to detect cracking in the vertical radius (also known as the ``vertical leg'') of the upper cap of the center wing rear spar, and repair if necessary. This proposed AD expands the area to be inspected by including inspections to detect cracking of the horizontal flange of the upper cap of the left and right center wing rear spar, and repair if necessary. This proposed AD also adds certain airplanes to the applicability. This proposed AD results from reports of cracking in the vertical radius of the upper cap of the center wing rear spar, and the horizontal flange on the inboard side of the rear spar upper cap, which resulted from stress corrosion. We are proposing this AD to detect and correct cracking in the vertical leg or the horizontal flange of the upper cap of the left or right center wing rear spar, which could cause a possible fuel leak, damage to the wing skin, and structural failure of the upper cap, and result in reduced structural integrity of the airplane.

We propose to adopt a new airworthiness directive (AD) for certain Model 747-400, 747-400D, and 747-400F series airplanes. This proposed AD would require modifying certain thrust reverser control system wiring to the flap control unit (FCU). This proposed AD results from a report of automatic retraction of the leading edge flaps due to indications transmitted to the FCU from the thrust reverser control system during takeoff. We are proposing this AD to prevent automatic retraction of the leading edge flaps during takeoff, which could result in reduced climb performance and consequent collision with terrain and obstacles or forced landing of the airplane.

This action proposes to establish five low altitude Area Navigation (RNAV) routes, designated T-281, T-283, T-285, T-286, and T- 288, over Nebraska and South Dakota; controlled by Denver Air Route Traffic Control Center (ARTCC) and Minneapolis ARTCC. T-routes are low altitude Air Traffic Service routes, based on RNAV, for use by aircraft that have instrument flight rules (IFR) approved Global Positioning System (GPS)/Global Navigation Satellite System (GNSS) equipment. This action would enhance safety and improve the efficient use of the navigable airspace within Denver and Minneapolis ARTCC airspace.

The FAA is correcting airworthiness directive (AD) 2010-14-19, which published in the Federal Register on July 13, 2010. That AD applies to certain Model A330-200 and -300 series airplanes, and Model A340-200, -300, -500 and -600 series airplanes. A certain service bulletin number in Note 3 of the regulatory section is incorrect. This document corrects that service bulletin number. In all other respects, the original document remains the same.

These special conditions are issued for certain Dassault Aviation Model Falcon 7X airplanes. This airplane will have an advanced, enhanced flight-visibility system (EFVS), which is a novel or unusual design feature consisting of a head-up display (HUD) system modified to display forward-looking infrared (FLIR) imagery. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.

We are adopting a new airworthiness directive (AD) for certain Model 767-200, -300, and -300F series airplanes. This AD requires inspecting to verify the part number of the low-pressure flex-hoses of the flightcrew and supernumerary oxygen system installed under the oxygen mask stowage box at flightcrew and supernumerary oxygen mask locations, and replacing the flex-hose with a new non-conductive low- pressure flex-hose if necessary. This AD results from reports of low- pressure flex-hoses of the flightcrew oxygen system that burned through due to inadvertent electrical current from a short circuit in an adjacent audio select panel. We are issuing this AD to prevent inadvertent electrical current, which can cause the low-pressure flex- hoses used in the flightcrew and supernumerary oxygen systems to melt or burn, resulting in oxygen system leakage and smoke or fire.

We are adopting a new airworthiness directive (AD) for certain Model 747 airplanes. This AD requires inspecting to verify the part number of the low-pressure flex-hoses of the crew oxygen system installed under the oxygen mask stowage boxes in the flight deck, and replacing the flex-hose with a new non-conductive low-pressure flex- hose if necessary. This AD results from reports of low-pressure flex- hoses of the crew oxygen system that burned through due to inadvertent electrical current from a short circuit in the audio select panel. We are issuing this AD to prevent inadvertent electrical current, which can cause the low-pressure flex-hoses of the crew oxygen system to melt or burn, causing oxygen system leakage and smoke or fire.

We are superseding an existing airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by an airworthiness authority of another country to identify and correct an unsafe condition on an aviation product. The earlier MCAI, Brazilian Airworthiness Directive 2007-08-02, effective September 27, 2007, describes the unsafe condition as:

This amendment adopts a new airworthiness directive (AD) for the specified Eurocopter France helicopters. This action requires inspecting certain electrical harnesses for damage and if damage is found, repairing the electrical harness; protecting the electrical harness from damage; installing harness clamp blocks; and inspecting each fairing attachment screw to determine the length and replacing attachment screws, if they exceed a certain length. This amendment is prompted by a report of an in-flight incident that led to the inflation of the emergency floatation gear (emergency floats) and the activation of various warnings. The actions specified in this AD are intended to prevent interference between an electrical harness and the lower structure fairing attachment screws. Damage to an electrical harness by a lower structure fairing attachment screw could lead to short- circuiting of various warnings, inflation of the emergency floats during flight, and subsequent loss of control of the helicopter.

We are revising an earlier NPRM for the products listed above. This action revises the earlier NPRM by expanding the scope. 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:

These special conditions are issued for the Embraer ERJ 190- 100 series airplane. This airplane will have novel or unusual design features that include non-traditional, large, non-metallic panels that would affect survivability during a post-crash fire event. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.

This document makes a correction to a proposed airworthiness directive (AD), which was published in the Federal Register on July 9, 2010 (75 FR 39472), and applies to certain Eclipse Aerospace, Inc. (Eclipse) Model EA500 airplanes. This NPRM proposed to require incorporating changes to the electronic flight information system and the airplane flight manuals. The FAA incorrectly referenced the applicability for Model EA500 airplanes with certain serial numbers (SNs) of this proposed AD as ``000039 through 000104, 000113 through 000115, 000120, and 000123 through 000124, that incorporate Performance Enhancement & Drag Reduction Modification per any revision level of Eclipse SB 500-99-001'' instead of ``000039 through 000104, 000113 through 000115, 000120, and 000123 through 000124, that incorporate Avionics Upgrade to AVIO NG Configuration for ETT Configured Aircraft per any revision level of Eclipse SB 500-99-002.'' This document corrects the aircraft configuration of these applicable SNs. We are issuing this document to help eliminate any confusion that this proposed AD may have created.
