Airworthiness Directives; Airbus Model A310 Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Model A310 series airplanes. This proposed AD would require measuring the clearance between the compensator and the guide assembly of probe no. 1 on the outboard fuel tanks, and performing corrective actions if necessary. This proposed AD is prompted by the results of fuel system reviews conducted by the manufacturer. We are proposing this AD to prevent interference between the compensator and the guide assembly of probe no. 1, which could create an ignition source that could result in a fire or explosion.
Airworthiness Directives; Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. This proposed AD would require installing additional shielding of the hydraulic lines in the wing box area. This proposed AD is prompted by the determination that the additional hydraulic line shields will protect the lines from possible impact by tire debris if the tire tread fails. We are proposing this AD to prevent damage to the hydraulic lines and subsequent leakage from the two hydraulic systems, which could result in loss of braking capability on the affected side of the airplane, asymmetrical braking, and reduced directional controlparticularly during a rejected takeoff.
Airworthiness Directives; Boeing Model 757-200 and -300 Series Airplanes and Model 767 Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 757-200 and -300 series airplanes and Model 767 series airplanes. This proposed AD would require replacing the existing operational software of the Pegasus flight management computer (FMC) system with new, improved operational software. This proposed AD is prompted by 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 proposing this AD to prevent display of ``old'' or expired 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.
Airworthiness Directives; Boeing Model 767 Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for all Boeing Model 767 series airplanes. This proposed AD would require an inspection of each main tank fuel boost pump for the presence of a pump shaft flame arrestor, and if the flame arrestor is missing, replacement of that pump with a pump having a pump shaft flame arrestor. This proposed AD would also require repetitive measurements of the flame arrestor's position in the pump, and corrective actions if necessary. This proposed AD is prompted by reports that certain fuel boost pumps may not have flame arrestors installed in the pump shaft. We have also received reports that the pin that holds the flame arrestor in place can break due to metal fatigue. We are proposing this AD to prevent the possible migration of a flame from a main tank fuel boost pump inlet to the vapor space of that fuel tank, and consequent ignition of fuel vapors, which could result in a fire or explosion should the pump inlets become uncovered.
Airworthiness Directives; Boeing Model 777-200 and -300 Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 777-200 and -300 series airplanes. This proposed AD would require inspecting the valve control and indication wire bundles of the fuel system of the wing rear spar for discrepancies, and corrective action if necessary. This proposed AD is prompted by reports of six incidents of the wire bundles chafing against the rear spar stiffeners outside the fuel tank. We are proposing this AD to prevent this chafing, which could result in wire damage leading to a short circuit, subsequent ignition of flammable vapors, and possible uncontrollable fire during fueling or flight.
Airworthiness Directives; McDonnell Douglas Model MD-11 and -11F Airplanes; Model DC-10-10 and DC-10-10F Airplanes; Model DC-10-15 Airplanes; Model DC-10-30 and DC-10-30F (KC-10A and KDC-10) Airplanes; Model DC-10-40 and DC-10-40F Airplanes; and Model MD-10-10F and MD-10-30F Airplanes
The FAA proposes to supersede an existing airworthiness directive (AD) that applies to certain McDonnell Douglas Model MD-11 and -11F airplanes. The existing AD currently requires a one-time inspection to detect loose preload-indicating (PLI) washers or cracked or corroded nuts of the lower bolts of the inboard flap outboard hinge, and replacement with new parts if necessary. This proposed AD would require replacement with new, improved parts of the inboard flap, outboard hinge, forward attach bracket, and lower attach bolt assemblies. This proposed AD also would add certain other McDonnell Douglas transport category airplanes and require an inspection for certain parts, and related investigative and corrective actions if necessary. This proposed AD is prompted by a report indicating that the left-hand inboard flap outboard hinge pulled away from the wing structure. We are proposing this AD to prevent loose PLI washers or cracked or corroded nuts of the lower bolts of the inboard flap outboard hinge, which could result in separation of the inboard flap outboard hinge from the wing structure and consequent reduced controllability of the airplane.
Airworthiness Directives; Boeing Model 737-100, -200, -200C, -300, -400, and -500, Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for all Boeing Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This proposed AD would require an inspection for chafing of certain wire bundles located above the center fuel tank, corrective actions if necessary, and replacement of wire bundle clamps with new clamps. This proposed AD is prompted by the results of fuel system reviews conducted by the manufacturer. We are proposing this AD to prevent chafed wire bundles near the center fuel tank, which could cause electrical arcing through the tank wall and ignition of fuel vapor in the fuel tank, and result in a fuel tank explosion.
Airworthiness Directives; Boeing Model 727 Airplanes, Equipped With An Auxiliary Fuel Tank Having a Fuel Pump Installed
The FAA proposes to adopt a new airworthiness directive (AD) for Boeing Model 727 airplanes equipped with an auxiliary fuel tank having a fuel pump installed. This proposed AD would require revising the airplane flight manual to include limitations on operating the fuel pumps for the auxiliary fuel tank. This proposed AD is prompted by a design review of the fuel pump installation, which revealed a potential unsafe condition related to the auxiliary fuel tank(s). We are proposing this AD to prevent dry operation of the fuel pumps for the auxiliary fuel tank, which could create a potential ignition source inside the auxiliary fuel tank that could result in a fire or explosion of the auxiliary fuel tank.
Airworthiness Directives; Boeing Model 737-100, -200, -200C, -300, -400, and -500 Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for all Boeing Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This proposed AD would require repetitive inspections of the stiffeners at left buttock line (LBL) and right buttock line (RBL) 6.15 for cracks; and replacement of both stiffeners with new, improved stiffeners if any stiffener is found cracked. This proposed AD would also allow replacement of both stiffeners at LBL and RBL 6.15 with new, improved stiffeners, which terminates the repetitive inspections. This proposed AD is prompted by reports of cracks in the stiffeners at LBL and RBL 6.15 on the rear spar of the wing center section. We are proposing this AD to detect and correct cracks in the stiffeners at LBL and RBL 6.15, which could result in damage to the keel beam structure and consequently reduce the capability of the airplane to sustain flight loads.
Airworthiness Directives; Boeing Model 767 Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 767 series airplanes. This proposed AD would require replacing hinge assemblies with new hinge assemblies in the outboard overhead stowage bins and reworking hinge assemblies in the outboard overhead stowage bins that are adjacent to curtain tracks. This proposed AD is prompted by reports of hinge assemblies of outboard overhead stowage bins breaking or the stowage bin doors not latching properly. We are proposing this AD to prevent the outboard overhead stowage bins opening during flight and releasing baggage, and consequently cause passenger injury and blockage of the aisles during emergency egress.
Airworthiness Directives; Dornier Model 328-300 Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Dornier Model 328-300 series airplanes. This proposed AD would require installing a drain hole in the lower skin of the left- and right-hand elevator horns. This proposed AD is prompted by reports of water found in the elevator assembly. We are proposing this AD to prevent water or ice accumulating in the elevator assembly, which could result in possible corrosion that reduces the structural integrity of the flight control surface, or in an unbalanced flight control surface. These conditions could result in reduced controllability of the airplane.
Airworthiness Directives; Boeing Model 737-300, -400, -500, -600, -700, -700C, -800 and -900 Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 737-300, -400, -500, -600, -700, -700C, -800 and -900 series airplanes. This proposed AD would require installing an updated version of the operational program software (OPS) in the flight management computers (FMCs), and doing other specified actions. This proposed AD would also require reinstalling software, if necessary. This proposed AD is prompted by one operator reporting FMC map shifts on several Model 737-400 series airplanes with dual FMCs, using OPS version U10.4A. We are proposing this AD to prevent the FMC from displaying the incorrect actual navigation performance value to the flightcrew, which could prevent adequate alerting of a potential navigation error. This condition could result in a near miss with other airplanes or terrain, or collision if other warning systems also fail.
Standard Airworthiness Certification of New Aircraft
The FAA seeks public comments on a proposal to amend the regulations for issuing a standard airworthiness certificate to certain new aircraft manufactured in the United States. The proposal addresses a concern that under the current regulations, certain new aircraft are eligible for a standard airworthiness certificate without meeting the requirements of a type certificate and without having been manufactured under an FAA production approval. The intended effect of this proposal is to ensure that new aircraft manufactured in the United States that receive a standard airworthiness certificate are type certificated and manufactured under an FAA production approval. The FAA also proposes to incorporate requirements contained in laws recently passed by Congress. A holder of a type certificate or supplemental type certificate who allows another person to use the certificate would have to provide written permission to that person. In addition, any person who manufactures an aircraft, aircraft engine, or propeller based on a type certificate would have to either hold the type certificate or have a licensing agreement from the holder. The proposal would also prohibit a person from altering an aircraft based on a supplemental type certificate (STC) unless the owner or operator either holds the STC or has written permission from the holder. Additionally, it would require the owner or operator of an aircraft that has been altered based on written permission to use a supplemental type certificate to retain that permission and transfer it at the time the aircraft is sold.
Special Conditions: Boeing Model 747-100/200B/200F/200C/SR/SP/100B/300/ 100B SUD/400/400D/400F Airplanes; Flammability Reduction Means (Fuel Tank Inerting)
These special conditions are issued for the Boeing Model 747- 100/200B/200F/200C/SR/SP/100B/300/100B SUD/400/400D/400F series airplanes. These airplanes, as modified by Boeing Commercial Airplanes, include a new flammability reduction means that uses a nitrogen generation system to reduce the oxygen content in the center wing fuel tank so that exposure to a combustible mixture of fuel and air is substantially minimized. This system is intended to reduce the average flammability exposure of the fleet of airplanes with the system installed to a level equivalent to 3 percent of the airplane operating time. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for the design and installation of this system. These special conditions contain the additional safety standards the Administrator considers necessary to ensure an acceptable level of safety for the installation of the system and to define performance objectives the system must achieve to be considered an acceptable means for minimizing development of flammable vapors in the fuel tank installation.

Airworthiness Directives; DG Flugzeugbau GmbH Model DG-500MB Sailplanes and Glaser-Dirks Flugzeugbau GmbH Model DG-800B Sailplanes
The FAA proposes to adopt a new airworthiness directive (AD) for all DG Flugzeugbau GmbH Model DG-500MB sailplanes equipped with a Solo engine and Glaser-Dirks Flugzeugbau GmbH Model DG-800B sailplanes equipped with a Solo engine. This proposed AD would require you to inspect the propeller for damage, specifically foam core separation, and replace any damaged propeller. This proposed AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. We are issuing this proposed AD to detect and correct damage to the propeller, which could result in failure of the propeller to perform properly. This failure could lead to reduced or loss of control of the sailplane.
Airworthiness Directives; Boeing Model 747 Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 747 airplanes. This proposed AD would require repetitive inspections of the dual side braces (DSBs), underwing midspar fittings, and associated parts; other specified actions; and corrective actions if necessary. This proposed AD also provides an optional terminating action for the inspections and other specified actions. This proposed AD is prompted by reports of corroded, migrated, and rotated bearings for the DSBs in the inboard and outboard struts, a report of a fractured retainer for the eccentric bushing for one of the side links of a DSB, and reports of wear and damage to the underwing midspar fitting on the outboard strut. We are proposing this AD to prevent the loss of a DSB or underwing midspar fitting load path, which could result in the transfer of loads and motion to other areas of a strut, and possible separation of a strut and engine from the airplane during flight.
Reports by Carriers on Incidents Involving Animals During Air Transport
The Department of Transportation (Department or DOT) is making a technical change to the August 11, 2003, final rule implementing section 710 of the Wendell H. Ford Aviation Investment and Reform Act for the 21st Century (AIR-21) to require the reporting airlines to submit the required information on the loss, injury, or death of an animal during air transport to DOT's Aviation Consumer Protection Division rather than the Animal and Plant Health Inspection Service (APHIS) of the United States Department of Agriculture (USDA) and, accordingly, is making the rule part of DOT's economic regulations.
Airworthiness Directives; Eurocopter France Model AS350B, BA, B1, B2, B3, C, D, D1, and EC130 B4 Helicopters
This amendment adopts a new airworthiness directive (AD) for Eurocopter France (Eurocopter) Model AS350B, BA, B1, B2, B3, C, D, D1, and EC130 B4 helicopters that requires removing and modifying the fuel bleed lever. This amendment is prompted by some cases of loss of the fuel bleed lever in flight. If the tension of the control cable is too low, the cable may vibrate out of its notch, resulting in the fuel bleed lever separating from the hinge. The actions specified by this AD are intended to prevent a fuel bleed lever from separating and striking the tail rotor blade (blade), resulting in damage to or loss of a blade, and subsequent vibration and loss of control of the helicopter.
Airworthiness Directives; Eurocopter France Model EC 155B, EC155B1, SA-360C, SA-365C, SA-365C1, SA-365C2, SA-365N, SA-365N1, AS-365N2, AS 365 N3, and SA-366G1 Helicopters
This amendment adopts a new airworthiness directive (AD) for the specified Eurocopter France (Eurocopter) model helicopters. This action requires an initial and repetitive borescope inspection of the main gearbox (MGB) planet gear carrier or an initial and repetitive visual inspection of the MGB planet gear carrier for a crack. Replacing any MGB that has a cracked planet gear carrier is required before further flight. This amendment is prompted by the discovery of cracks in the web of the planet gear carrier. The actions specified in this AD are intended to detect a crack in the web of the planet gear carrier, which could lead to a MGB seizure and subsequent loss of control of the helicopter.
Airworthiness Directives; Airbus Model A300 B2 and B4 Series Airplanes
This amendment supersedes an existing airworthiness directive (AD) that applies to all Airbus Model A300 B2 and B4 series airplanes. The existing AD currently requires determining the part and amendment number of the variable lever arm (VLA) of the rudder control system to verify the parts were installed using the correct standard, and corrective actions if necessary. For certain VLAs, this new AD requires repetitive inspections of the VLA and corrective action if necessary. This new AD also provides a terminating action for the repetitive inspections. Furthermore, this new AD reduces the applicability of affected airplanes. The actions specified by this AD are intended to prevent failure of both spring boxes of certain VLAs due to corrosion damage, which could result in loss of rudder control and consequent reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
Airworthiness Directives; Airbus Model A330, A340-200, and A340-300 Series Airplanes
This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A330, A340-200, and A340-300 series airplanes. This AD requires initial and repetitive inspections of certain frame stiffeners to detect cracking. If any cracking is found, this AD requires replacement of the stiffener with a new, reinforced stiffener. Replacement of the stiffener constitutes terminating action for certain inspections. This AD also requires a one-time inspection of any new, reinforced stiffener; and repair or replacement of the new, reinforced stiffener if any cracking is found during the one-time inspection. This AD also provides for an optional terminating action for certain requirements of this AD. The actions specified by this AD are intended to prevent fatigue failure of certain frame stiffener fittings, which could result in reduced structural integrity of the airplane. This action is intended to address the identified unsafe condition.
Airworthiness Directives; Raytheon Model DH.125, HS.125, and BH.125 Series Airplanes; BAe.125 Series 800A (C-29A and U-125) and 800B Airplanes; and Hawker 800 (Including Variant U-125A) and 800XP Airplanes; Equipped with TFE731 Engines
The FAA is adopting a new airworthiness directive (AD) for certain Raytheon Model DH.125, HS.125, and BH.125 series airplanes; BAe.125 series 800A (C-29A and U-125) and 800B airplanes; and Hawker 800 (including variant U-125A) and 800XP airplanes. This AD requires installing insulating blankets on the engine compartment firewall and the wire harness passing through the firewall fairlead. This AD is prompted by a report indicating that insulation on the wire harness passing through the firewall fairlead ignited on the fuselage side of the firewall. We are issuing this AD to prevent a fire in the engine compartment from causing possible ignition of outgassing wire insulation on the fuselage side of the firewall, which could lead to an uncontrollable fire in the fuselage.
Airworthiness Directives; BAE Systems (Operations) Limited Model BAe 146 Series Airplanes and Model Avro 146-RJ Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain BAE Systems (Operations) Limited Model BAe 146 series airplanes and Model Avro 146-RJ series airplanes. This AD requires repetitive inspections to detect discrepancies of the fuselage skin and reinforcing plates along the wing to fuselage fairing access panels on the left- and right-hand sides of the airplane, and repair if necessary. This AD also provides for an optional terminating action for the repetitive inspections. This AD is prompted by a report of chafing on the wing to fuselage fairing panels. We are issuing this AD to prevent chafing of the fuselage skin and reinforcing plates, which could lead to reduced structural integrity of the airplane's fuselage.
Airworthiness Directives; Pilatus Aircraft Limited Models B4- PC11, B4-PC11A, and B4-PC11AF Sailplanes
The FAA proposes to adopt a new airworthiness directive (AD) for all Pilatus Aircraft Limited (Pilatus) Models B4-PC11, B4-PC11A, and B4-PC11AF sailplanes. This proposed AD would require you to repetitively inspect the control-column support for cracks and, if any cracks are found, replace the control-column support with a new support. This proposed AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Switzerland. We are issuing this proposed AD to detect and correct cracks in the control-column support, which could result in failure of the support. This failure could lead to loss of the primary flight control system.
Airworthiness Directives; Bell Helicopter Textron, A Division of Textron Canada Model 222, 222B, 222U and 230 Helicopters
This amendment supersedes an existing airworthiness directive (AD) for Bell Helicopter Textron, A Division of Textron Canada (BHTC) Model 222, 222B, 222U, and 230 helicopters, that currently requires a visual check of each main rotor grip (grip) and pitch horn assembly without disassembling the main rotor hub assembly (hub assembly), and a visual inspection at specified intervals of each affected grip and pitch horn assembly for a crack using a 10-power or higher magnifying glass. If a crack is found, the existing AD requires replacing each unairworthy grip or pitch horn with an airworthy part before further flight. This amendment requires those same actions, and also requires an additional inspection of the grip and pitch horn assembly for a crack in the disassembled hub assembly, and replacing any cracked part with an airworthy part. This amendment is prompted by the determination that an additional enhanced inspection is needed to ensure the integrity of the hub assembly. The actions specified by this AD are intended to prevent failure of the grip or pitch horn and subsequent loss of control of the helicopter.
Redesignation of Mountainous Areas in Alaska
This final rule updates the designated mountainous areas in the State of Alaska. Regulations currently designating mountainous areas in Alaska were established in 1956. Since that time, we have concluded that areas previously considered non-mountainous should be expanded, and two areas previously designated mountainous should be considered non-mountainous. This final rule will allow aircraft operating in certain non-mountainous areas to fly at altitudes acceptable for the actual topography of the area.
Airworthiness Directives; Boeing Model 767-200 and -300 Series Airplanes
The FAA is superseding an existing airworthiness directive (AD), which applies to certain Boeing Model 767 series airplanes. That AD currently requires repetitive detailed and eddy current inspections of the aft pressure bulkhead for damage and cracking, and repair if necessary. This new AD also requires one-time detailed and high frequency eddy current inspections of any ``oil-can'' located on the aft pressure bulkhead, and related corrective actions if necessary. An ``oil-can'' is an area on a pressure dome web that moves when pushed from the forward side. This AD is prompted by reports of cracking at ``oil-can'' boundaries on the aft pressure bulkhead. We are issuing this AD to detect and correct fatigue cracking of the aft pressure bulkhead, which could result in rapid depressurization of the airplane and possible damage or interference with the airplane control systems that penetrate the bulkhead, and consequent loss of controllability of the airplane.
Airworthiness Directives; MD Helicopters, Inc. Model 600N Helicopters
This document proposes superseding an existing airworthiness directive (AD) for the MD Helicopters, Inc. (MDHI) Model 600N helicopters. That AD currently requires certain inspections of both upper tailboom attachments, nutplates, and angles for a crack or thread damage, and repairing or replacing any cracked or damaged part. Also, that AD requires replacing certain tailboom attachment bolts, adding a washer to each bolt, and modifying both upper access covers. This action would require installing six additional inspection holes in the aft fuselage skin panels and inspecting the upper and lower tailboom attachment fittings, the upper longerons, and the angles and nutplates for cracks. Also, the AD would provide a terminating action of modifying the fuselage aft section to strengthen the tailboom attachments and longerons. This proposal is prompted by an analysis that shows that certain tailboom attachments and longerons may develop cracks. The actions specified by the proposed AD are intended to prevent failure of a tailboom attachment, loss of the tailboom, and subsequent loss of control of the helicopter.
Airworthiness Directives; Raytheon Aircraft Company 90, 99, 100, 200, and 300 Series Airplanes
This document incorporates corrections to Airworthiness Directive (AD) 2005-01-04, which was published in the Federal Register on January 6, 2005 (70 FR 1169) with regulatory corrections published on January 27, 2005 (70 FR 3871). AD 2005-01-04 applies to certain Raytheon Aircraft Company 90, 99, 100, 200, and 300 series airplanes. This action incorporates the corrections into one document to help eliminate any confusion. We are re-issuing the AD in its entirety.
Membership in the National Parks Overflights Advisory Group
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. This notice informs the public of two vacancies on the NPOAG (now the NPOAG Aviation Rulemaking Committee) for members representing environmental interests and invites interested persons to apply to fill the vacancies.
Airworthiness Directives; Agusta S.p.A. Model A109E Helicopters
This document proposes adopting a new airworthiness directive (AD) for Agusta S.p.A. (Agusta) Model A109E helicopters. This proposal would require visually inspecting each main transmission support fitting (fitting) attachment bolt (bolt) for a fracture, a crack, or looseness, and verifying the torque on each fitting bolt. This proposal is prompted by two incidents of fatigue failure of the bolts that secure the transmission rear support fittings to the helicopter. The actions specified by this proposed AD are intended to detect a fracture, a crack, or looseness of a fitting bolt, and prevent fatigue failure of a fitting bolt and subsequent loss of control of the helicopter.
Airworthiness Directives; Eurocopter France Model AS355E, F, F1, F2, and N Helicopters
This document proposes superseding an existing airworthiness directive (AD) for the specified Eurocopter France (ECF) model helicopters. That AD currently requires replacing certain main or combiner gearboxes with airworthy gearboxes. Further investigation has shown that the main gearbox is not affected, and this action would require replacing a certain combiner gearbox with a modified airworthy gearbox. This proposal is prompted by a report of a freewheel unit slipping resulting in an engine overspeed and shutdown. Also, this proposal is prompted by the conclusion of the investigation, which finds the freewheel slippage is due to the surface treatment applied to certain freewheel rollers in the combiner gearbox. The actions specified by the proposed AD are intended to prevent an engine overspeed, an engine shutdown, and subsequent loss of control of the helicopter.
Airworthiness Directives; Bell Helicopter Textron Canada Model 407 Helicopters
This amendment adopts a new airworthiness directive (AD) for Bell Helicopter Textron Canada (Bell) Model 407 helicopters that requires creating a component history card or equivalent record for each crosstube assembly, converting accumulated run-on landings to an accumulated Retirement Index Number (RIN) count, and establishing a maximum accumulated RIN for certain crosstube assemblies. This amendment is prompted by fatigue testing, analysis, and evaluation by the manufacturer that determined that run-on landings impose a high stress on landing gear or crosstubes and may cause cracking in the area above the skid tube saddle. The actions specified by this AD are intended to prevent fatigue failure in a crosstube assembly due to excessive stress during run-on landings and subsequent loss of control of the helicopter.
Airworthiness Directives; Agusta S.p.A. Model A119 Helicopters
This document proposes adopting a new airworthiness directive (AD) for Agusta S.p.A. (Agusta) Model A119 helicopters. This proposal would require visually inspecting each main transmission support fitting (fitting) attachment bolt (bolt) for a fracture, a crack, or looseness, and verifying the torque on each fitting bolt. This proposal is prompted by two incidents of fatigue failure of the bolts that secure the transmission rear support fittings to the helicopter. The actions specified by this proposed AD are intended to detect a fracture, a crack, or looseness of a fitting bolt, and prevent fatigue failure of a fitting bolt and subsequent loss of control of the helicopter.
Airworthiness Directives; Eurocopter France Model EC120 Helicopters
This document proposes adopting a new airworthiness directive (AD) for Eurocopter France (Eurocopter) Model EC120 helicopters. This proposal would require inspecting the tail rotor drive shaft (drive shaft) damper half-clamps (half-clamps) to determine if they are centered on the friction ring, and if not correctly positioned, centering the half-clamps on the friction ring. This proposal is prompted by the discovery of half-clamps that were incorrectly positioned. This condition, if not detected, could result in interference of the two half-clamps with the drive shaft, which could result in scoring on the drive shaft, failure of the drive shaft, and subsequent loss of control of the helicopter.
Airworthiness Directives; Boeing Model 747-100, -100B, -100B SUD, -200B, -200C, -200F, and -300 Series Airplanes; and Model 747SP and 747SR Series Airplanes; Equipped With Pratt & Whitney Model JT9D-3, and -7 Series Engines
The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing transport category airplanes listed above. This proposed AD would require repetitive inspections for cracks of the upper surface of the aft lower spar web of the inboard and outboard struts, as applicable; and repetitive inspections for cracks of the upper surface of the intermediate web bay of the aft lower spar. This proposed AD would also require repetitive inspections and torque checks of the bolts common to the aft lower spar chords and the fitting of the rear engine mount bulkhead for missing, loose, or fractured bolts, as applicable; and corrective action, if necessary. This proposed AD is prompted by reports of cracking in the aft lower spar web and reports of missing and fractured bolts. We are proposing this AD to detect and correct cracking of the aft lower spar web, and to prevent missing, loose, or fractured bolts common to the aft lower spar chords and the fitting of the rear engine mount bulkhead, which could result in the loss of the aft lower spar load path and reduced structural capability of the pylon, which may result in the separation of the engine from the airplane.

Modification of Class E Airspace; Ozark, MO
This action amends Title 14 Code of Federal Regulations, part 71 (14 CFR part 71) by revising Class E airspace at Ozark, MO. A review of the Class E airspace area extending upward from 700 feet above ground level (AGL) at Ozark, MO revealed it is not in compliance with established airspace criteria. This airspace area is enlarged and modified to conform to FAA Orders. The intended effect of this rule is to provide controlled airspace of appropriate dimensions to protect aircraft departing from and executing Standard Instrumental Approach Procedures (SIAPs) to Air Park South Airport. This rule also amends the Air Park South Airport airport reference point (ARP) in the legal description to reflect current data. The area is modified and enlarged to conform to the criteria in FAA Orders.
Modification of Class E Airspace; Nevada, MO
This action amends Title 14 Code of Federal Regulations, part 71 (14 CFR part 71) by revising Class E airspace at Nevada, MO. A review of the Class E airspace area extending upward from 700 feet above the surface at Nevada, MO, revealed it does not reflect the current Nevada Municipal Airport airport reference point (ARP) nor the correct location of the Nevada nondirectional radio beacon (NDB) and is not in compliance with established airspace criteria. Extensions to this airspace area are enlarged and modified to conform to FAA Orders. The intended effect of this rule is to provide controlled airspace of appropriate dimensions to protect aircraft departing from and executing Standard Instrument Approach Procedures (SIAPs) to Nevada Municipal Airport.
Airworthiness Directives; Rolls-Royce Deutschland Ltd. & Co KG (formerly Rolls-Royce plc), Model Tay 611-8, 620-15, 650-15, and 651-54 Turbofan Engines
The FAA is superseding an existing airworthiness directive (AD) for Rolls-Royce Deutschland Ltd. & Co KG (RRD) (formerly Rolls- Royce plc) Model Tay 611-8, 620-15, 650-15, and 651-54 turbofan engines, with low pressure (LP) fuel tube, part number (P/N) JR33021A, installed. That AD currently requires initial and repetitive inspections of the LP fuel tubes. This AD requires the same inspections and adds a requirement to replace the fuel tube with a new design tube, as mandatory terminating action to the repetitive inspections. This AD results from the manufacturer introducing a new design fuel tube, which eliminates the unsafe condition. We are issuing this AD to prevent a dual-engine flameout due to fuel exhaustion, which could lead to forced landing and possible damage to the airplane.
Notice of Meeting of the National Parks Overflights Advisory Group Aviation Rulemaking Committee
The National Park Service (NPS) and Federal Aviation Administration (FAA), in accordance with the National Parks Air Tour Management Act of 2000, announce the next meeting of the National Parks Overflights Advisory Group Aviation Rulemaking Committee (NPOAG ARC). This notice informs the public of the date, location, and agenda for the meeting. Dates and Location: The NPOAG ARC will meet February 23-25, 2005, at the Holiday Inn Sunspree Resort, 520 Historic Nature Trail, Gatlinburg, TN 37738. The meeting will begin at 8:30 a.m. on Wednesday, February 23, 2005.
Airworthiness Directives; Air Tractor, Inc. Models AT-502, AT-502A, AT-502B, and AT-503A Airplanes
The FAA proposes to supersede Airworthiness Directive (AD) 2002-26-05, which applies to certain Air Tractor, Inc. (Air Tractor) Models AT-502, AT-502A, AT-502B, and AT-503A airplanes. AD 2002-26-05 lowers the safe life for the wing lower spar cap for Models AT-502, AT- 502A, AT-502B, and AT-503A airplanes and those that incorporate or have incorporated Marburger Enterprises, Inc. winglets. AD 2002-26-05 also requires you to eddy-current inspect the wing lower spar cap immediately prior to the replacement/modification to detect and correct any crack in a bolthole before it extends to the modified center section of the wing and report the results of this inspection to the Federal Aviation Administration (FAA). Since we issued AD 2002-26-05, we have determined that additional airplanes should be added to the applicability section. We also developed an alternative method of compliance (AMOC) to the requirements of AD 2002-26-05. This proposed AD retains the action required in AD 2002-26-05, adds additional airplanes to the applicability, and includes an AMOC. We are issuing this proposed AD to prevent fatigue cracks from occurring in the wing lower spar cap before the established safe life is reached. Fatigue cracks in the wing lower spar cap could result in the wing separating from the airplane during flight.
Airworthiness Directives; The New Piper Aircraft, Inc. PA-34 Series Airplanes
The FAA proposes to supersede Airworthiness Directive (AD) 93- 24-14, which applies to all The New Piper Aircraft, Inc. (Piper) PA-34 series airplanes. AD 93-24-14 currently requires you to repetitively replace the bolt and stack up that connect the upper drag link to the nose gear trunnion. This proposed AD is the result of many service difficulty reports related to the collapse or inadvertent retraction of the nose landing gear (NLG). Consequently, this proposed AD would retain the actions required in AD 93-24-14 until the actions of the proposed AD would begin, require you to inspect the NLG and components of the NLG using new procedures for rigging the nose gear installation, and require you to replace unserviceable parts. We are also issuing this proposed AD to detect, correct, and prevent future 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.
Special Conditions: Boeing Model 747SP; NASA Stratospheric Observatory for Infrared Astronomy (SOFIA); Cryogenic Systems Using Liquid Nitrogen and Liquid Helium
This notice proposes special conditions for the Boeing Model 747SP airplane. This airplane, as modified by L-3 Communications/ Integrated Systems of Waco, Texas, will have novel and unusual design features associated with cryogenic systems using liquid nitrogen and liquid helium. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These proposed 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.
