Airworthiness Directives; Boeing Model 747-100, -100B, 100B SUD, -200B, and -300 Series Airplanes; and Model 747SP and 747SR Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 747-100, -100B, 100B SUD, -200B, and -300 series airplanes; and Model 747SP and 747SR series airplanes. This proposed AD would replace certain requirements of an existing AD. This proposed AD would require repetitive inspections to detect cracks in various areas of the upper deck floor beams, and repair if necessary. This proposed AD is prompted by the results of fatigue testing that revealed severed upper chords of the upper deck floor beams due to fatigue cracking. We are proposing this AD to detect and correct cracking in the upper chords of the upper deck floor beams. Undetected cracking could result in large deflection or deformation of the upper deck floor beams, resulting in damage to wire bundles and control cables for the flight control system, and reduced controllability of the airplane. Multiple adjacent severed floor beams could result in rapid decompression of the airplane.
Airworthiness Directives; Various Transport Category Airplanes Manufactured by McDonnell Douglas
The FAA proposes to revise an existing airworthiness directive (AD) that applies to various transport category airplanes manufactured by McDonnell Douglas. The existing AD currently requires a one-time test of the fire extinguishers for the engine and auxiliary power unit (APU), as applicable, to determine the capability of the Firex electrical circuits to fire discharge cartridges, and troubleshooting actions if necessary. This proposed AD would remove certain transport category airplanes from the applicability of the existing AD. This proposed AD is prompted by reports indicating that fire extinguishers for the engine and auxiliary power unit had failed to discharge when commanded. We are proposing this AD to prevent failure of the fire extinguishers to fire discharge cartridges, which could result in the inability to put out a fire in an engine or in the APU.
Airworthiness Directives; Aviointeriors S.p.A. (formerly ALVEN), Series 312 Box Mounted Seats
The FAA proposes to adopt a new airworthiness directive (AD) for Aviointeriors S.p.A. (formerly ALVEN), series 312 box mounted seats. This proposed AD would require initial and repetitive inspections of the seat attachments for cracks, and if necessary, replacing the attachments. This proposed AD results from 10 reports of cracked attachments of series 312 box mounted seats. We are proposing this AD to prevent series 312 box mounted seats from detaching from the passenger compartment floor, which could result in injury to the occupant of the seat, and prevent evacuation of passengers in the event of an emergency.
Airworthiness Directives; Boeing Model 747-200F and -200C Series Airplanes
This amendment supersedes an existing airworthiness directive (AD), applicable to all Boeing Model 747-200F and -200C series airplanes, that currently requires repetitive detailed inspections or a one-time open-hole high frequency eddy current inspection to detect cracking of certain areas of the upper deck floor beams, and corrective actions if necessary. This amendment requires new one-time inspections for cracking of the web, upper chord, and strap of the upper deck floor beams. This action also requires modifying or repairing the upper deck floor beams, as applicable, which eventually necessitates accomplishment of new repetitive inspections for cracking of the upper deck floor beams. The actions specified by this AD are intended to prevent fatigue cracks in the upper chord and web of upper deck floor beams and the resultant failure of such floor beams. Failure of a floor beam could result in damage to critical flight control cables and wire bundles that pass through the floor beam, and consequent loss of controllability of the airplane. Failure of the floor beam also could result in the failure of the adjacent fuselage frames and skin, and consequent rapid decompression of the airplane. This action is intended to address the identified unsafe condition.
Airworthiness Directives; Saab Model SAAB 2000 Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Saab Model SAAB 2000 series airplanes. This AD requires a one- time inspection to detect a broken terminal stud on a main relay of the electrical power generator, and corrective action if necessary. This AD is prompted by disconnection of an electrical power generator during an inspection flight, which was caused by a broken terminal stud on the main relay. We are issuing this AD to prevent a broken terminal stud on the main relay of an electrical power generator, which could reduce the redundancy of electrical power systems, result in increased pilot workload, and contribute to reduced controllability of the airplane.
Airworthiness Directives; Airbus Model A300 B2 and B4 Series Airplanes; Model A300 B4-600, A300 B4-600R, A300 C4-605R Variant F, and A300 F4-600R (Collectively Called A300-600) Series Airplanes; and Model A310 Series Airplanes
The FAA is superseding an existing airworthiness directive (AD), which applies to certain Airbus Model A300 B2 and B4 series airplanes; Model A300 B4-600, A300 B4-600R, A300 C4-605R Variant F, and A300 F4-600R (collectively called A300-600) series airplanes; and Model A310 series airplanes. That AD currently requires replacement of the transformer rectifier units (TRUs) in the avionics compartment with new, improved TRUs. This new AD requires replacement of the TRUs installed according to the existing AD with different TRUs that are improved. This AD is prompted by analysis that has revealed that certain diodes installed in the TRUs are the main factor contributing to the continuing TRU failures. We are issuing this AD to prevent failure of the TRUs. Failure of multiple TRUs could result in loss of the thrust reversers, autothrottle, flaps, and various systems (wing/ cockpit window anti-ice, trim tank pumps, and windshield wipers) on the airplane; or display of incorrect information to the flightcrew.
Airworthiness Directives; Aviointeriors S.p.A. Series 312 Seats
The FAA is superseding an existing airworthiness directive (AD), that is applicable to Aviointeriors S.p.A. (formerly ALVEN), series 312 seats. That AD requires initial and repetitive inspections of the seat central crossmember for cracks, and if necessary, replacing the crossmember with a new crossmember. This ad requires the same actions and adds other crossmember part numbers for inspection. In addition, this AD replaces the original design crossmembers with reinforced design crossmembers as optional terminating actions to the repetitive inspections. This AD results from reports of 88 cracked seat central crossmembers and 60 aisle side crossmembers, to date; and, from the introduction of reinforced optional seat crossmembers by the manufacturer. We are issuing this AD to prevent the loss of the structural integrity of the seat due to cracks in seat crossmembers, which could lead to passenger injury.
Airworthiness Directives; Dassault Model Falcon 10 Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for all Dassault Model Falcon 10 series airplanes. This AD requires revising the Limitations section of the airplane flight manual (AFM) to include a statement prohibiting flight into known or forecasted icing conditions, and installing a placard in the flight deck. In lieu of the AFM revision and placard installation, this AD allows identifying the part number of each flexible hose in the wing anti-icing system, performing repetitive detailed inspections of each hose for delamination, and performing corrective actions if necessary. This AD is prompted by a report of delamination of the internal wall of a flexible hose in the wing anti-icing system. We are issuing this AD to prevent collapse of the flexible hoses in the wing 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.
Airworthiness Directives; Boeing Model 777-200 and -300 Series Airplanes Equipped With Rolls Royce Model RB211 TRENT 800 Engines
The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 777-200 and -300 series airplanes. This AD requires inspecting the thrust reversers for damage of the insulation blankets, the inner wall, and the compression and drag link fittings; and repair if necessary. This AD also requires applying sealant to certain areas of the thrust reverser. This AD is prompted by two reports of thrust reverser failure; investigation revealed that the inner wall of the thrust reversers had collapsed from exposure to hot engine core compartment air. We are issuing this AD to prevent failure of a thrust reverser and adjacent components and their consequent separation from the airplane, which could result in a rejected takeoff (RTO) and cause asymmetric thrust and consequent loss of control of the airplane during reverse thrust operation. If an RTO does not occur, these separated components could cause structural damage to the airplane or damage to other airplanes and possible injury to people on the ground.
Airworthiness Directives; the Cessna Aircraft Company Models 208 and 208B Airplanes
This document makes a correction to Airworthiness Directive (AD) 2005-07-01, which was published in the Federal Register on March 25, 2005 (70 FR 15223), and applies to all the Cessna Aircraft Company (Cessna) Models 208 and 208B airplanes. We incorrectly referenced the affected airplane models as C208 and C208B throughout the document. The correct airplane models are 208 and 208B. This action corrects the regulatory text.
Federal Motor Vehicle Safety Standards; Tire Pressure Monitoring Systems; Controls and Displays
This final rule establishes a new Federal motor vehicle safety standard (FMVSS) requiring installation of a tire pressure monitoring system (TPMS) capable of detecting when one or more of a vehicle's tires is significantly under-inflated. This final rule responds to a mandate in the Transportation Recall Enhancement, Accountability, and Documentation (TREAD) Act. This final rule requires installation in all new light vehicles of a TPMS capable of detecting when one or more of the vehicle's tires, up to all four tires, is 25 percent or more below the manufacturer's recommended inflation pressure (placard pressure) or a minimum activation pressure specified in the standard, whichever is higher.

Airworthiness Directives; Eurocopter France Model AS350B, BA, B1, B2, B3, D, and AS355E Helicopters
This document proposes adopting a new airworthiness directive (AD) for the specified Eurocopter France (ECF) model helicopters. This proposal would require replacing the hydraulic fluid at a specified time interval when operating in cold weather. This proposal is prompted by reports of ice forming due to condensation in some parts of the hydraulic system during cold weather operation. The actions specified by this proposed AD are intended to prevent ice from forming in the hydraulic system resulting in an unintended movement of the flight controls and subsequent loss of control of the helicopter.
Airworthiness Directives; Bombardier Model CL-600-2B16 (CL-604) Series Airplanes
The FAA withdraws a notice of proposed rulemaking (NPRM) that proposed a new airworthiness directive (AD) for certain Bombardier Model CL-600-2B16 (CL-604) series airplanes. The proposed AD would have required replacing the side-brace fitting shafts of the main landing gear (MLG) with new, improved side-brace fitting shafts; inspecting for corrosion of the MLG side-brace fitting shafts; and replacing the nut, washer, and cotter pin of the MLG side-brace fitting shafts with new parts; as applicable. Since the proposed AD was issued, we have received new data that the actions that would have been required by the proposed AD have already been accomplished on all of the affected airplanes. Accordingly, the proposed AD is withdrawn.
Airworthiness Directives; McDonnell Douglas Model DC-10-10, DC-10-10F, DC-10-15, DC-10-30, DC-10-30F (KC-10A and KDC-10), DC-10-40, DC-10-40F, MD-10-10F, MD-10-30F, MD-11, and MD-11F Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain McDonnell Douglas airplanes identified above. This proposed AD would require repetitive functional tests for noisy or improper operation of the exterior emergency control handle assemblies of the mid, overwing, and aft passenger doors, and corrective actions if necessary. This proposed AD also would provide for optional terminating action for the repetitive tests. This proposed AD is prompted by a report that the exterior emergency control mechanism handles were inoperative on a McDonnell Douglas MD-11 airplane. We are proposing this AD to prevent failure of the passenger doors to operate properly in an emergency condition, which could delay an emergency evacuation and possibly result in injury to passengers and flightcrew.
Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model ERJ 170 Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for all Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model ERJ 170 series airplanes. This AD requires revising the Limitations section of the airplane flight manual to advise the flightcrew to make sure the correct instrument landing system (ILS) identifier is included on the flight management system (FMS) flight plan before the flightcrew initiates an approach to landing with the autopilot engaged. This AD is prompted by reports that the airplane's autopilot may apply large- amplitude control inputs while following ILS guidance to a runway that is not included on the FMS flight plan. We are issuing this AD to prevent hazardous maneuvers close to the ground, which could result in an impact with an obstacle or terrain.

Airworthiness Directives; Boeing Model 737-100, -200C, -300, -400, and -500 Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for all Boeing Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This AD requires repetitive inspections for cracks in the fuselage skin, doubler, bearstrap, and frames surrounding the main, forward, and aft cargo doors; and repair of any cracking. This AD also requires inspections of certain existing repairs for cracking, and related corrective action if cracking is found. This AD is prompted by reports of multiple fatigue cracks in the fuselage skin and bonded skin doubler, bearstrap, and doorway frames surrounding the forward and aft cargo doors. We are issuing this AD to find and fix fatigue cracking in the fuselage skin, doubler, bearstrap, and frames, which could result in reduced structural integrity of the frames, possible loss of a cargo door, and consequent rapid decompression of the fuselage.
Airworthiness Directives; Boeing Model 737-600, -700, -800, and -900 Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 737-600, -700, -800, and -900 series airplanes. This AD requires installing and testing an updated version of the operational program software of the flight control computers. This AD is prompted by a report of an airplane pitching up with rapidly decreasing indicated airspeed after the flightcrew set a new altitude into the autopilot. We are issuing this AD to prevent anomalous autopilot operation that produces a hazardous combination of airplane attitude and airspeed, which could result in loss of control of the airplane.
Airworthiness Directives; Boeing Model 767-300 and -400ER Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 767-300 and -400ER series airplanes. This AD requires replacing the in-flight entertainment cooling card, located in the P50 card file in the main equipment center, with a new, improved cooling card. This AD is prompted by a report of an improperly designed component on the in-flight entertainment (IFE) cooling card, which may cause the IFE cooling system to incorrectly interpret signals from airplane system interfaces. We are issuing this AD to prevent failure of the IFE cooling card to configure itself correctly in response to input signals from airplane system interfaces during a forward cargo fire, which could result in the IFE cooling fan causing smoke to penetrate occupied areas of the airplane.
Airworthiness Directives; Boeing Model 737-100, -200, -200C, -300, -400, and -500 Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This AD requires repetitive detailed and eddy current inspections to detect cracking of the frame web around the cutout for the doorstop intercostal strap at the aft side of the body station 291.5 frame at stringer 16R, and corrective actions if necessary. This AD is prompted by reports of fatigue cracks in the web of the body station 291.5 frame near the forward galley door. We are issuing this AD to detect and correct fatigue cracking of the aft frame and frame support structure of the forward galley door, which could result in a severed fuselage frame web, rapid decompression of the airplane, and possible loss of the forward galley door.
Airworthiness Directives; Bombardier Model DHC-8-102, -103, -106, -201, -202, -301, -311, and -315 Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Bombardier Model DHC-8-102, -103, -106, -201, -202, -301, -311, and-315 airplanes. This AD requires revising the airplane flight manual to include applicable procedures to follow when the flightcrew receives abnormal indications of airspeed, altitude, or vertical airspeed. This AD also requires modifying the static system. This AD is prompted by a report of a leak in the static pressure system, which could result in loss of the static systems and consequent erroneous data displayed on the pilot's flight instruments. We are issuing this AD to advise the flightcrew of applicable procedures in the event of abnormal indications of airspeed, altitude, or vertical airspeed; and to prevent leaks in the static system, which could result in the loss of critical flight information that could result in reduced controllability of the airplane or controlled flight into terrain.
Airworthiness Directives; Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Bombardier Model CL-600-2B19 (Regional Jet Series 100 and 440) airplanes. This AD requires modification of the Auxiliary Power Unit (APU) cooling air exhaust. This AD is prompted by reports of incomplete drainage of the APU enclosure. We are issuing this AD to prevent a negative pressure condition from developing in the APU enclosure when the APU is operating on the ground, which could create a potential fire hazard if flammable liquid leakage occurs inside the APU enclosure and cannot be drained overboard.
Airworthiness Directives; Airbus Model A318, A319, A320, and A321 Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for all Airbus Model A318, A319, A320, and A321 series airplanes. This AD requires an inspection of the spoiler servo control for certain part numbers, and corrective action if necessary. This AD is prompted by a report of a broken piston rod bearing of the spoiler servo control. We are issuing this AD to prevent breakage of the piston rod bearing, which could cause loss of the associated hydraulic system and spoiler extension, and could result in reduced controllability of the airplane.
Airworthiness Directives; Boeing Model 767-400ER, 777-200, and 777-300 Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 767-400ER, 777-200, and 777-300 series airplanes. This AD requires replacing, with new parts, the existing tie-down fitting studs that secure galleys, purser work stations, and closets to the seat tracks. This AD is prompted by a report that tie-down fitting studs were found damaged. We are issuing this AD to prevent a galley, purser work station, or closet from detaching from the tie-down fitting studs during an emergency landing, which could injure passengers or crewmembers, or obstruct escape routes and impede emergency evacuation.
Regulations Governing Fees for Services Performed in Connection With Licensing and Related Services-2005 Update
The Board adopts its 2005 User Fee Update and revises its fee schedule to recover the costs associated with the January 2005 Government salary increases and to reflect changes in overhead costs to the Board.
Hazardous Materials: Hazardous Waste Manifest Requirements; Withdrawal of Notice of Proposed Rulemaking
The Research and Special Programs Administrationthe predecessor agency to the Pipeline and Hazardous Materials Safety Administration (PHMSA)and the Environmental Protection Agency (EPA) issued final rules in 1980 requiring that a manifest accompany each shipment of hazardous waste during transportation. In 49 CFR 172.205, PHMSA provided that the uniform manifest ``may be used as the shipping paper required by'' the Hazardous Materials Regulations, so long as it contained all the required information. On May 22, 2001, EPA published a notice of proposed rulemaking (NPRM) to revise the hazardous waste manifest system. One of EPA's proposed changes would have allowed the uniform manifest to be prepared and transmitted electronically from the generator to the disposal facility, rather than requiring it to accompany the shipment. EPA is deferring final action on the electronic manifest pending further analysis, outreach, and possible supplemental proposals. Therefore, PHMSA is withdrawing an NPRM published on August 8, 2001, that would have amended the Hazardous Materials Regulations on the use of the Uniform Hazardous Waste Manifest for shipments of hazardous wastes. The changes proposed in that NPRM would have accommodated changes proposed by EPA. PHMSA proposed to require that, if the generator of a hazardous waste prepares an electronic manifest, either a physical copy of the electronic manifest or another document containing the information required for a shipping paper must accompany the hazardous waste in transportation.

Airworthiness Directives; Hartzell Propeller Inc. (Formerly TRW Hartzell Propeller) Models HC-B3TN-2, HC-B3TN-3, HC-B3TN-5, HC-B4TN-3, HC-B4TN-5, HC-B4MN-5, and HC-B5MP-3 Turbopropellers
The FAA is revising an existing airworthiness directive (AD), that is applicable to Hartzell Propeller Inc. (formerly TRW Hartzell Propeller) models HC-B3TN-2, HC-B3TN-3, HC-B3TN-5, HC-B4TN-3, HC-B4TN- 5, HC-B4MN-5, and HC-B5MP-3 turbopropellers. That AD requires, before further flight, that all new propellers being installed and all serviceable propellers being reinstalled, are attached using part number (P/N) B-3339 bolts and P/N A-2048-2 washers, and that the bolts are properly torqued. That AD also requires a onetime torque-check of P/N A-2047 bolts that are already installed through propellers and replacement of those bolts if necessary, with P/N B-3339 bolts and P/N A-2048-2 washers. This AD requires the same actions, and includes the use of other equivalent FAA-approved serviceable bolts and washers. This AD results from the need to make nonsubstantive wording changes and additions to clarify that terminating action is achieved by attaching propellers with P/N B-3339 bolts and P/N A-2048-2 washers or other equivalent FAA-approved serviceable bolts and washers, to the engine flange, as instructed in the compliance section of this AD. We are issuing this AD to preclude propeller attaching bolt failures or improperly secured propellers, which could lead to separation of the propeller from the airplane.
Airworthiness Directives; MT-Propeller Entwicklung GmbH Propellers
The FAA proposes to adopt a new airworthiness directive (AD) for certain MT-Propeller Entwicklung GmbH variable pitch and fixed pitch propellers with serial numbers (SNs) below 95000, which have not been overhauled since April 1994. This proposed AD would require you to perform initial and repetitive visual inspections of those propeller blades. Further, this proposed AD would require you to remove all propeller blades from service with damaged erosion sheath bonding or loose erosion sheaths and to install any missing or damaged polyurethane protective strips. This proposed AD results from reports of stainless steel leading edge erosion sheaths separating from propeller blades and reports of propeller blades missing or without polyurethane protective strips due to insufficient inspection procedures in older MT-Propeller Entwicklung GmbH Operation & Installation Manuals. We are proposing this AD to prevent erosion sheath separation leading to damage of the airplane.
Airworthiness Directives; Goodrich De-icing and Specialty Systems “FASTprop” Propeller De-icers
The FAA proposes to adopt a new airworthiness directive (AD) for Goodrich De-icing and Specialty Systems ``FASTprop'' propeller de- icers, part numbers P4E1188 series, P4E1601 series, P4E2200 series, P4E2271-10, P4E2575-7, P4E2575-10, P4E2598-10, P5855BSW, P6199SW, P6592SW, P6662SW, and P6975-11, installed. This proposed AD would require inspection, repair, or replacement of those ``FASTprop'' propeller de-icers that fail visual checks before the first flight each day. This proposed AD results from reports of Goodrich ``FASTprop'' propeller de-icers becoming loose or debonded, and detaching from propeller blades during operation. We are proposing this AD to prevent Goodrich ``FASTprop'' propeller de-icers from detaching from the propeller blade, resulting in damage to the airplane and possible injury to the passengers and crewmembers.
Airworthiness Directives; Teledyne Continental Motors GTSIO-520 Series Reciprocating Engines
The FAA proposes to adopt a new airworthiness directive (AD) for Teledyne Continental Motors (TCM) GTSIO-520 series reciprocating engines. This proposed AD would require initial and repetitive visual inspections of the starter adapter assembly and crankshaft gear. This proposed AD would also require unscheduled visual inspections of the starter adapter assembly and crankshaft gear due to a rough-running engine. This proposed AD would also require replacement of the starter adapter shaft gear needle bearing with a certain bushing. Also, this proposed AD would require installation of a certain TCM service kit at the next engine overhaul, or at the next starter adapter replacement, whichever occurs first. Also, this proposed AD would require adding a certain placard to the instrument panel before further flight. This proposed AD results from six service difficulty reports and one fatal accident report received related to failed starter adapter assemblies. We are proposing this AD to prevent failure of the starter adapter assembly and or crankshaft gear, resulting in failure of the engine and possible forced landing.
Airworthiness Directives; Turbomeca Artouste III Series Turboshaft Engines
The FAA proposes to adopt a new airworthiness directive (AD) for Turbomeca Artouste III series turboshaft engines. This proposed AD would require modification of the engine air intake assembly. This proposed AD results from a report of an in-flight shutdown and subsequent loss of control of the helicopter due to ice ingestion into the engine. We are proposing this AD to prevent ice ingestion into the engine, which could lead to an in-flight shutdown and subsequent loss of control of the helicopter.
Airworthiness Directives; Dornier Model 328-100 and -300 Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Dornier Model 328-100 and -300 series airplanes. This proposed AD would require operators to install colored identification strips on the pulley brackets, fairlead bracket assemblies, operational assemblies, and flight control cables. This proposed AD is prompted by a report that the flight control systems do not have elements that are distinctively identified. We are proposing this AD to prevent the incorrect re-assembly of the flight control system during maintenance, which could result in reduced controllability of the airplane.
Airworthiness Directives; BAE Systems (Operations) Limited (Jetstream) Model 4101 Airplanes
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 the overhaul of certain auxiliary components installed on the main landing gear (MLG) and nose landing gear (NLG). This proposed 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 proposing this AD to prevent failure of the MLG or NLG, and consequent damage to the airplane and injury to flightcrew and passengers.
Airworthiness Directives; Fokker Model F.28 Mark 0100 Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for all Fokker Model F.28 Mark 0100 series airplanes. This proposed AD would require an inspection to determine the part number of the passenger service unit (PSU) panels for the PSU modification status, and corrective actions if applicable. This proposed AD is prompted by reported incidents of smoke in the passenger compartment during flight. One of those incidents also included a burning smell and consequently led to emergency evacuation of the airplane. We are proposing this AD to prevent overheating of the PSU panel due to moisture ingress, which could result in smoke or fire in the passenger cabin.
Airworthiness Directives; Bombardier Model DHC-8-102, -103, -106, -201, -202, -301, -311, and -315 Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Bombardier Model DHC-8-102, -103, -106, -201, -202, -301, - 311, and -315 airplanes. This proposed AD would require revising the airworthiness limitations section of the Instructions for Continued Airworthiness by incorporating new and revised structural inspection procedures and new and revised inspection intervals for the longitudinal skin joints in the fuselage pressure shell. This proposed AD would also require phase-in inspections and repair of any crack found during any phase-in inspection. This proposed AD is prompted by a report indicating that visual inspections were not adequate for detecting fatigue cracking in portions of the longitudinal skin joints in the fuselage pressure shell. We are proposing this AD to detect and correct fatigue cracking of the longitudinal skin joints in the fuselage pressure shell, which could affect the structural integrity of the airplane, and result in loss of cabin pressurization during flight.
Airworthiness Directives; Airbus Model A300 B2 and B4 Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Model A300 B2 and B4 series airplanes. This proposed AD would require modifying the wiring of the autopilot pitch torque limiter switch. This proposed AD is prompted by several reports of pitch trim disconnect caused by insufficient length in the wiring to the pitch torque limiter lever. We are proposing this AD to prevent possible trim loss when the flightcrew tries to override the autopilot pitch control, which could result in uncontrolled flight of the airplane.
Airworthiness Directives; Learjet Model 23, 24, 24A, 24B, 24B-A, 24C, 24D, 24D-A, 24E, 24F, 24F-A, 25, 25A, 25B, 25C, 25D, 25F, 28, 29, 31, 31A, 35, 35A (C-21A), and 36 Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Learjet Model 23, 24, 24A, 24B, 24B-A, 24C, 24D, 24D-A, 24E, 24F, 24F-A, 25, 25A, 25B, 25C, 25D, 25F, 28, 29, 31, 31A, 35, 35A (C-21A), and 36 airplanes. This proposed AD would require a one-time inspection of the center ball of the aileron control cable or cables for a defective swage, and corrective actions if necessary. This proposed AD is prompted by a report indicating that an aileron cable failed on one affected airplane when the cable underwent a tension check. We are proposing this AD to prevent severe weakening of the aileron cable, and consequent reduced controllability of the airplane.
Airworthiness Directives; Airbus Model A319, A320, and A321 Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Model A319, A320, and A321 series airplanes. This proposed AD would require modifying the parking brake system to automatically restore the normal parking brake if the parking brake pressure decreases below a certain threshold. This proposed AD is prompted by a report of failure of the parking brake while the airplane was on the holding point of the runway before takeoff, leading to a runway departure. We are proposing this AD to ensure normal braking is available to prevent possible runway departure in the event of failure of the parking brake.
Airworthiness Directives; McDonnell Douglas Model 717-200 Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain McDonnell Douglas Model 717-200 airplanes. This proposed AD would require repetitively replacing and testing a certain relay of the passenger oxygen release system in the forward cabin. This proposed AD is prompted by reports of a failed relay of the passenger oxygen release system. We are proposing this AD to prevent failure of the relay, which could result in the oxygen masks failing to deploy and deliver oxygen to the passengers in the event of a rapid decompression or cabin depressurization.
Airworthiness Directives; Bombardier Model DHC-8-400, -401, and -402 Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Bombardier Model DHC-8-400, -401, and -402 airplanes. This proposed AD would require revising the Airworthiness Limitation section of the Instructions for Continued Airworthiness of the Dash 8 400 Series (Bombardier) Maintenance Requirements Manual to reduce the life limits of the main landing gear (MLG) orifice support tube, upper bearing, and piston plug; and to reduce the threshold for initiating repetitive detailed inspections for cracking of the engine isolator brackets. This proposed AD is prompted by the discovery of fatigue failures, during type certification fatigue testing, at the engine isolator bracket and at the orifice support tube, upper bearing, and piston plug in the shock strut assembly of the MLG, which are principal structural elements. We are proposing this AD to prevent the development of cracks in these principal structural elements, which could reduce the structural integrity of the engine installation and the MLG. Reduced structural integrity of the engine installation could result in separation of the engine from the airplane, and reduced structural integrity of the MLG could result in collapse of the MLG.
Airworthiness Directives; Dornier Model 328-100 and -300 Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Dornier Model 328-100 and -300 series airplanes. This proposed AD would require a pressure test and detailed inspection of each fuselage drain line to determine if there is a blockage, and related investigative/corrective actions if necessary. This proposed AD is prompted by a report of leakage at one of the drain lines in the fuselage. We are proposing this AD to prevent blockage within the drain lines, causing fluids to collect. These fluids may freeze and expand, damaging the drain lines, and allowing fuel to leak into the cabin and fuel vapors to come into contact with ignition sources, which could result in consequent fire in the cabin.
Airworthiness Directives; Fokker Model F.28 Mark 1000, 2000, 3000, and 4000 Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for all Fokker Model F.28 Mark 1000, 2000, 3000, and 4000 series airplanes. This proposed AD would require a detailed inspection to determine the presence of incorrectly installed bushings in the attachment holes of the reinforcing strap of the left- and right-hand wings' lower skin, and corrective actions if necessary. This proposed AD is prompted by a report that bushings were installed in accordance with improper procedures in the structural repair manual. We are proposing this AD to detect and correct improperly installed bushings, which could result in reduced tensile strength of the reinforcing strap of the wing's lower skin, and consequently a reduction of the structural capability of the wing and possible wing failure.
Airworthiness Directives; Fokker Model F.28 Mark 0070 and 0100 Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for all Fokker Model F.28 Mark 0070 and 0100 series airplanes. This proposed AD would require repetitive inspections for damage of the drive rod assembly of the aileron tab on each aileron actuator; repetitive measurements of the clearance between the aileron hydraulic lines and the drive rod; and related investigative and corrective actions if necessary. This proposed AD is prompted by a report of an aileron 2 fault caused by severe wear of the polyamide washer that is part of an anti-rotation bush assembly in the aileron attachment lug. We are proposing this AD to prevent excessive wear of the polyamide washer of the aileron actuator bush assembly, which could result in aileron flutter and loss of control of the airplane.
Airworthiness Directives; Airbus Model A300 B4-600, B4-600R, and F4-600R Series Airplanes, and Model C4-605R Variant F Airplanes (Collectively Called A300-600 Airplanes)
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Model A300-600 airplanes. This proposed AD would require an inspection for evidence of chafing between the hydraulic flexible hose and the ram air turbine (RAT) hub, and related investigative and corrective actions if necessary. This proposed AD is prompted by reports of holes in the RAT hub cover. We are proposing this AD to prevent a hole in the RAT hub cover. A hole in the RAT hub cover could allow water to enter the RAT governing mechanism, freeze during flight, and jam the governing mechanism. In addition, the metal particles that result from chafing between the hydraulic flexible hose and the RAT could mix with the lubricant grease and degrade the governing mechanism. In an emergency, a jammed or degraded RAT could result in its failure to deploy, loss of hydraulic pressure or electrical power to the airplane, and consequent reduced controllability of the airplane.
