Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-135 and -145 Series Airplanes
The FAA proposes to supersede an existing airworthiness directive (AD) that applies to certain EMBRAER Model EMB-135 and -145 series airplanes. The existing AD currently requires revising the airplane flight manual (AFM) to prohibit in-flight auxiliary power unit (APU) starts, and installing a placard on or near the APU start/stop switch panel to provide such instructions to the flightcrew. This proposed AD would add an optional revision to the AFM that allows limited APU starts and would add a terminating action. This proposed AD is prompted by the airplane manufacturer developing modifications that revise or eliminate the need for restrictions to in-flight APU starts. We are proposing this AD to prevent flame backflow into the APU compartment through the eductor during in-flight APU starts, which could result in fire in the APU compartment.
Airworthiness Directives; Boeing Model 707 Airplanes and Model 720 and 720B Series Airplanes
The FAA proposes to supersede an existing airworthiness directive (AD) that applies to certain Boeing Model 707 airplanes and Model 720 and 720B series airplanes. The existing AD currently requires a preventive modification of the front spar fitting on the outboard engine nacelle. This proposed AD would remove the requirement to do this preventive modification, and would require repetitive inspections for cracking of the front spar fitting of the inboard and outboard nacelle struts, and replacement of any cracked fitting with a new fitting. The proposed AD would also apply to more airplanes. This proposed AD is prompted by a report indicating that a crack was found in a front spar fitting that had been replaced as part of the modification required by the existing AD. We are proposing this AD to detect and correct this cracking, which could result in reduced structural integrity of the engine nacelle, and consequent separation of an engine from the airplane.
Civil Penalty Assessment Procedures; Correction
This action makes minor editorial corrections to the final rule published in the Federal Register on October 4, 2004 (69 FR 59490) and technical corrections to one of the regulations it amended. That final rule adopted changed procedures concerning initiating and adjudicating an administratively assessed civil penalty against an individual acting as a pilot, flight engineer, mechanic, or repairman. Corrections include a quote and reference in the preamble, the removal of a redundant paragraph in the rule language, and several cross references to, and a typographical error in, redesignated paragraphs.
Airworthiness Directives; Bombardier-Rotax GmbH Type 912 F, 912 S, and 914 F Series Reciprocating Engines
The FAA is superseding an existing airworthiness directive (AD) for Bombardier-Rotax GmbH Type 912 F, 912 S, and 914 F series reciprocating engines. That AD currently requires venting of the lubrication system and inspection of the valve train on all engines. That AD also requires venting of the lubrication system of all engines on which the lubrication system has been opened, and any engine on which the propeller has been rotated one full turn in the wrong direction. This AD requires similar actions, and also requires removing the existing part number oil dipstick from service and installing a new oil dipstick. This AD results from the need to clarify the mandated procedures for inspections and venting. This AD also results from the manufacturer discovering that under certain circumstances, the oil level in the oil tank can fall below the minimum level required to sustain proper engine lubrication. We are issuing this AD to prevent damage to the engine valve train due to inadequate venting of the lubrication system, which can result in an in-flight engine failure and forced landing.

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 any petition or its final disposition.
Airworthiness Directives; Boeing Model 757-200, -200PF, and -200CB Series Airplanes
This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 757-200, -200PF, and -200CB series airplanes, that requires an inspection of certain ballscrews of the trailing edge flap system to find their part numbers, and replacement of the ballscrews with new, serviceable, or modified ballscrews if necessary. This action is necessary to prevent a flap skew due to insufficient secondary load path of the ballscrew of the trailing edge flaps in the event that the primary load path fails, which could result in possible loss of a flap and reduced controllability of the airplane. This action is intended to address the identified unsafe condition.

This action proposes to revise the Class E airspace at Point Lay, AK. Three new Standard instrument approach procedures (SIAP's) are being published for Point Lay, AK. Additional Class E airspace is needed to contain aircraft executing instrument approaches at Point Lay Airport. Adoption of this proposal would result in additional Class E airspace upward from 1,200 feet (ft.) above the surface at Point Lay, AK.
Special Conditions; The New Piper Aircraft, Inc.; PA-46-350P and PA-46-500TP; Protection of Systems for High Intensity Radiated Fields (HIRF)
These special conditions are issued to The New Piper Aircraft, Inc.; Vero Beach, Florida, for a type design change for the PA-46-350P and PA-46-500TP model airplanes. These airplanes will have novel and unusual design features when compared to the state of technology envisaged in the applicable airworthiness standards. These novel and unusual design features include the installation of electronic flight instrument system (EFIS) displays Model 700-00006-003 Entegra, manufactured by Avidyne Corporation, Inc., for which the applicable regulations do not contain adequate or appropriate airworthiness standards for the protection of these systems from the effects of high intensity radiated fields (HIRF). These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to the airworthiness standards applicable to these airplanes.
Airworthiness Directives; Boeing Model 757-200, -200PF, -200CB, and -300 Series Airplanes
This document corrects two typographical errors that appeared in airworthiness directive (AD) 2004-23-06 that was published in the Federal Register on November 16, 2004 (69 FR 67047). The errors resulted in an incorrect reference to an amendment number and an incorrect reference to a service bulletin. This AD applies to certain Boeing Model 757-200, -200PF, -200CB, and -300 series airplanes. This AD requires inspection for damage of the W2800 wire bundle insulation, wire conductor, the wire bundle clamp bracket, and the BACC10GU( ) clamp, and repair or replacement with new or serviceable parts, if necessary. This AD also requires installation of spacers between the clamp and the bracket.
Process for Requesting Waiver of Mandatory Separation Age for Certain Federal Aviation Administration (FAA) Air Traffic Control Specialists
This final rule establishes procedures and some standards by which an air traffic controller in a flight service station, en route or terminal facility, or at the David J. Hurley Air Traffic Control System Command Center may request a waiver of the mandatory separation age. By taking this action, the Secretary of the Department of Transportation (DOT) implements congressional authority to issue such exemptions.
Airworthiness Directives; Pilatus Aircraft Ltd. Models PC-12 and PC-12/45 Airplanes
The FAA adopts a new airworthiness directive (AD) for all Pilatus Aircraft Ltd. (Pilatus) Models PC-12 and PC-12/45 airplanes. This AD requires you to check the airplane logbook to determine whether any main landing gear (MLG) actuator (part number (P/N) 960.30.01.103) with serial numbers (SNs) 830E through 881E is installed. If any MLG actuator with one of these SNs is installed, you are required to replace the MLG actuator with a P/N 960.30.01.103 actuator that has a SN other than 830E through 881E. The pilot is allowed to do the logbook check. If the pilot can positively determine that no MLG actuator with one of these SNs is installed, then no further action is required. This AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Switzerland. We are issuing this AD to prevent failure of the MLG actuator caused by an incorrect heat treating process, which could result in loss of hydraulic extension/retraction of the MLG. This failure could lead to loss of control during ground operations.
Airworthiness Directives; The New Piper Aircraft, Inc. Models PA-23-235, PA-23-250, and PA-E23-250 Airplanes
The FAA adopts a new airworthiness directive (AD) that supersedes Airworthiness Directive (AD) 74-06-01, which applies to certain The New Piper Aircraft, Inc. (Piper) Models PA-23-235, PA-23- 250, and PA-E23-250 airplanes equipped with Garrett Aviation Services (Garrett) (formerly AiResearch) turbosuperchargers installed under supplemental type certificate (STC) SA852WE, SA909WE, or SA978WE; or installed under Piper Aircraft Drawing Number 32016. AD 74-06-01 currently requires you to replace turbosupercharger oil tanks, install fire shrouds, seal all openings in the fire shrouds, and add drainage provisions in the oil tank fairings for airplane serial numbers 27-1 through 27-2504; and add drainage provisions in the air scoops on serial numbers 27-2505 and higher. This AD requires you to replace the oil reservoir and related hoses with a fireproof oil tank and fire- shielded hoses. This AD results from a report of a fatal accident related to the breakdown of the turbocharger oil reservoir following a fire in the engine nacelle. We are issuing this AD to prevent turbosupercharger oil reservoirs with inadequate fire resistance from failing when exposed to flame or exhaust gases. This failure could lead to an in-flight fire within the nacelle area penetrating the firewall and subsequent failure of the wing spar.
Airworthiness Directives; Airbus Model A310 Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for all Airbus Model A310 series airplanes. This AD requires modifying the wire routing of electrical harness 636VB in the right-hand wing. This AD is prompted by the manufacturer's analysis for compliance with Special Federal Aviation Regulation No. 88, which has shown that wiring 2M of the 115V anti-collision white strobe lights and wiring 2S of the fuel quantity indication system (FQIS) should be rerouted into separate conduits. We are issuing this AD to prevent chafing damage to wiring 2M and 2S, which could result in a short circuit and consequently introduce an electrical current into the wiring of the FQIS and create an ignition source in the fuel tank.
Airworthiness Directives; Boeing Model 747-100 and -200B Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 747-100 and -200B series airplanes. This AD requires installing bonding clips and bonding jumpers from the housing of each fuel pump to airplane structure outside the fuel tanks. This AD is prompted by the results of fuel system reviews conducted by the manufacturer. We are issuing this AD to ensure adequate electrical bonding between the housing of each fuel pump and airplane structure outside the fuel tanks. Inadequate electrical bonding, in the event of a lightning strike or pump electrical fault, could cause electrical arcing and ignition of fuel vapor in the wing fuel tank, which could result in a fuel tank explosion.
Airworthiness Directives; Airbus Model A310 Series Airplanes; and Model A300 B4-600, B4-600R, and F4-600R Series Airplanes, and Model C4 605R Variant F Airplanes (Collectively Called A300-600)
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A310 series airplanes; and Model A300 B4-600, B4- 600R, and F4-600R series airplanes, and Model C4 605R Variant F airplanes (collectively called A300-600). This AD requires relocating contactor 9DG located at rack (relay box) 107VU and adding protective sleeves to the two wire (cable) looms near the door hinge of rack 107VU. This AD is prompted by reports that interference was noticed during production between the wire looms located near the door hinge of rack 107VU and the terminals of contactor 9DG. We are issuing this AD to prevent possible short circuits in the wire looms supplying the fuel pump systems and the pitot probe heating system, which could lead to a possible loss of function of flight-critical systems and reduced controllability of the airplane.
Airworthiness Directives; Boeing Model 747-100, -200B, -200F, -200C, -100B, -300, -100B SUD, -400, -400D, -400F, and 747SR Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 747 series airplanes. This AD requires a one-time inspection for discrepancies of the frame web and inner chords on the forward edge frame of the number 5 main entry door cutout, and related corrective action. This AD is prompted by a report of cracking of the frame web and inner chords on the forward edge frame of the number 5 main entry door. We are issuing this AD to find and fix discrepancies of the frame web and inner chords, which could result in cracking, subsequent severing of the frame, and consequent rapid depressurization of the airplane.
Airworthiness Directives; Rolls-Royce Deutschland (RRD) (Formerly Rolls-Royce, plc) Tay 611-8, Tay 620-15, Tay 620-15/20, Tay 650-15, Tay 650-15/10, and Tay 651-54 Turbofan Engines
The FAA is superseding an existing airworthiness directive (AD) for certain RRD Tay 611-8, Tay 620-15, Tay 620-15/20, Tay 650-15, Tay 650-15/10, and Tay 651-54 turbofan engines with ice-impact panels installed in the low pressure (LP) compressor case. That AD currently requires visually inspecting all ice-impact panels and fillers in the LP compressor case for certain conditions, and if necessary, replacing any ice-impact panels and fillers that have those conditions. This AD requires initial and repetitive visual inspections of all ice-impact panels and fillers in the LP compressor case for certain conditions and replacing as necessary, any or all panels. This AD also introduces a new compliance date of no later than March 1, 2005, to have all but one engine on each airplane in compliance with the polysulfide bonding of panels. This AD results from RRD issuing two service bulletins since AD 2004-05-22 was published, that required repetitive visual inspections of panels, and defines a minimum configuration and repair standard. We are issuing this AD to prevent release of ice-impact panels due to improper bonding that can result in loss of thrust in both engines.
Airworthiness Directives; Raytheon Aircraft Company 90, 99, 100, 200, and 300 Series Airplanes
The FAA is adopting a new airworthiness directive (AD) to supersede (AD) 98-15-13, which applies to certain Raytheon Aircraft Company 90, 100, 200, and 300 series airplanes. This AD adds the Raytheon Beech 99 series to the applicability listed in AD 98-15-13. The compliance actions remain the same for those aircraft originally affected by AD 98-15-13. AD 98-15-13 currently requires you to check the airplane maintenance records from January 1, 1994, up to and including the effective date of that AD, for any MIL-H-6000B fuel hose replacements on the affected airplanes; inspecting any replaced rubber fuel hose for a spiral or diagonal external wrap with a red or orange- red stripe along the length of the hose with 94519 printed along the stripe; and replacing any MIL-H-6000B rubber fuel hose matching this description with an FAA-approved hose having a criss-cross or braided external wrap. We are issuing this AD to prevent fuel flow interruption, which could lead to uncommanded loss of engine power and loss of control of the airplane.
Airworthiness Directives; Boeing Model 747-400, 777-200, and 777-300 Series Airplanes
This document revises an earlier proposed airworthiness directive (AD), applicable to certain Boeing Model 747-400, 777-200, and 777-300 series airplanes, that would have required, for certain airplanes, replacement of the cell stack of the flight deck humidifier with a supplier-tested cell stack, or replacement with an end plate and subsequent deactivation of the flight deck humidifier. For other airplanes, that proposed AD would have required replacement of the cell stack with a blanking plate or a new cell stack, or replacement of the blanking plate with a supplier-tested cell stack. This new action revises the proposed AD by adding airplanes to the applicability; adding new inspections to determine certain part numbers; requiring replacement of the blanking plate with a supplier-tested cell stack if necessary; and changing certain words to clarify the intent of the proposed AD. The actions specified by this new proposed AD are intended to prevent an increased pressure drop across the humidifier and consequent reduced airflow to the flight deck, which could result in the inability to clear any smoke that might appear in the flight deck. This action is intended to address the identified unsafe condition.
Airworthiness Directives; Gulfstream Aerospace LP Model Gulfstream 100 Airplanes; and Model Astra SPX and 1125 Westwind Astra Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Gulfstream Aerospace LP Model Gulfstream 100 airplanes; and Model Astra SPX and 1125 Westwind Astra series airplanes. This AD requires adjusting the ground contact switches of the main landing gear. This AD is prompted by two occurrences of uncommanded deployments of the ground airbrakes during descent. We are issuing this AD to prevent a false ``Ground'' position signal, which could result in deployment of the ground airbrakes and reduced controllability of the airplane.
Airworthiness Directives; Airbus Model A320 Series Airplanes
The FAA is superseding an existing airworthiness directive (AD), which applies to certain Airbus Model A320 series airplanes. That AD currently requires repetitive inspections to detect fatigue cracking in certain areas of the fuselage, and corrective action if necessary. That AD also provides for an optional terminating action for the repetitive inspections. This new AD revises the compliance threshold and repetitive intervals for the inspections required by the existing AD. This AD is prompted by a full-scale fatigue survey on the Model A320 fleet. We are issuing this AD to detect and correct fatigue cracking of the fuselage, which could result in reduced structural integrity of the airplane.
Airworthiness Directives; Airbus Model A320 Series Airplanes
The FAA is superseding an existing airworthiness directive (AD), which applies to certain Airbus Model A320 series airplanes. That AD currently requires repetitive inspections to detect fatigue cracking in certain areas of the fuselage, and corrective action if necessary. That AD also provides for an optional terminating action for the repetitive inspections. This new AD reduces the compliance threshold and repetitive intervals for the inspections required by the existing AD. This AD is prompted by a full-scale fatigue survey on the Model A320 fleet. We are issuing this AD to detect and correct fatigue cracking of the fuselage, which could result in reduced structural integrity of the airplane.
Notice of Public Meeting
The Federal Aviation Administration (FAA) will hold a public meeting to gather additional comment and data on a proposed Airworthiness Directive published as a Notice of Proposed Rulemaking (NPRM), Docket Number FAA-2004-18038, (Directorate Identifier 2004-NE- 01-AD), in the Federal Register on June 16, 2004. This public meeting will follow the procedure provided in Sec. 11.53 of Title 14 of the Code of Federal Regulations (14 CFR 11.53).

Special Conditions: Dassault-Breguet Model Falcon 10 Airplane; High Intensity Radiated Fields (HIRF)
These special conditions are issued for a Dassault-Breguet Model Falcon 10 airplane modified by Long Beach Avionics of Long Beach, California. The modified airplane will have novel and unusual design features when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. The modification incorporates the installation of a Collins Model ALI-80 Altimeter and Model MSI-80 Mach Airspeed Indicator. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for the protection of these systems from the effects of high- intensity radiated fields (HIRF). These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that provided by the existing airworthiness standards.
Special Conditions: Airbus Model A330, A340-200 and A340-300 Series Airplanes; Lower Deck Mobile Crew Rest (LD-MCR) Compartment
These special conditions are issued for the Airbus Model A330, A340-200, and A340-300 series airplanes. These airplanes will have novel or unusual design features associated with a lower deck mobile crew rest (LD-MCR) compartment. 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.
Standard Instrument Approach Procedures; Miscellaneous Amendments
This amendment establishes, amends, suspends, or revokes Standard Instrument Approach Procedures (SIAPs) for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, addition of new obstacles, or changes in air traffic requirements. These changes are designed to provide safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.
Airworthiness Directives; Boeing Model 767-300 and 767-300F Series Airplanes Equipped With General Electric or Pratt & Whitney Engines
This amendment adopts a new airworthiness directive (AD), that is applicable to certain Boeing Model 767-300 and 767-300F series airplanes equipped with General Electric or Pratt & Whitney engines. This AD requires reworking the wing-to-strut diagonal braces and the aft pitch load fittings of the wings, and reinstalling the diagonal braces with new fuse pins and associated hardware. This action is necessary to prevent undetected loss of the diagonal brace fuse pins of the wings and consequent increased loads in other wing-to-strut joints, which could result in separation of the struts and engines from the wings. This action is intended to address the identified unsafe condition.
Airworthiness Directives; Airbus Model A318, A319, A320, and A321 Series Airplanes Equipped With Air Cruisers/Aerazur Forward and Aft Passenger Door Emergency Escape Slides
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A318, A319, A320, and A321 series airplanes equipped with certain forward and aft passenger door emergency escape slides. This AD requires modifying the forward and aft door slides. This AD is prompted by manufacturer testing that has shown contact between the inflation hose and fabric roll, within a short period of time after inflation of the emergency escape slides, can rupture the inflation hose at its end fittings. We are issuing this AD to prevent interference between the inflation hose and slide fabric and rupture of the inflation hose, which could result in incomplete inflation of the emergency escape slides and consequent unavailability of those slides during an emergency evacuation.
Airworthiness Directives; Rolls-Royce plc RB211-524 Series Turbofan Engines
The FAA is superseding an existing airworthiness directive (AD) for certain Rolls-Royce plc (RR) RB211-524 series turbofan engines. That AD currently requires initial and repetitive borescope insepctions of the head section and meterpanel assembly of the combustion liner, and replacement, if necessary, with serviceable parts. In addition, that AD allows an optional installation of a front combustion liner with a strengthened head section as a terminating action to the inspection requirements. This AD requires initial and repetitive borescope inspections of the head section and meterpanel assembly of the combustion liner, and replacement if necessary with serviceable parts. This AD also requires reduction of the inspection intervals of certain RB211-524 engine models that have not been repaired to RR Field Repair Scheme FRS5367/B, and a mandatory terminating action to be completed by a certain date. This AD results from five events that are directly attributed to combustor head breakup and meterpanel failure which were found at overhaul inspection. At least one of these events resulted in a combustion case burn-through. We are issuing this AD to prevent engine combustion liner deterioration, which can result in combustion liner breakup, case burn-through, and engine fire.
Airworthiness Directives; Pratt & Whitney JT8D-200 Series Turbofan Engines
The FAA is superseding existing airworthiness directive (AD) 99-22-14 for Pratt & Whitney (PW) JT8D-200 series turbofan engines. That AD currently requires removing low pressure turbine (LPT)-to- exhaust case bolts and nuts and replacement with improved LPT-to- exhaust case bolts and nuts on JT8D-209, -217, -217A, -217C, and -219 engines. That AD also requires installation of improved high pressure turbine (HPT) containment hardware on JT8D-217C, and -219 engines. This AD requires installation of improved HPT containment hardware on JT8D- 209, -217, -217A, -217C, and -219 engines. This AD results from four reports of uncontained HPT failures of JT8D-200 series engines, since AD 99-22-14 was issued. We are issuing this AD to prevent uncontained HPT events resulting from HPT shaft fractures.
Airworthiness Directives; Boeing Model 777-200 and -300 Series Airplanes
This document revises an earlier proposed airworthiness directive (AD), applicable to certain Boeing Model 777-200 and -300 series airplanes. That proposed AD would have required a one-time inspection of the clevis end of the vertical tie rods that support the center stowage bins to measure the exposed thread, installation of placards that advise of weight limits for certain electrical racks, a one-time inspection and records check to determine the amount of weight currently installed in those electrical racks, corrective actions, and replacement of the vertical tie rods for the center stowage bins or electrical racks with new improved tie rods, as applicable. This new action revises the proposed rule by revising the applicability to include additional airplanes. The actions specified by this new proposed AD are intended to prevent failure of the vertical tie rods supporting certain electrical racks and the center stowage bins, which could cause the center stowage bins or electrical racks to fall onto passenger seats below during an emergency landing, impeding an emergency evacuation or injuring passengers. This action is intended to address the identified unsafe condition.
Airworthiness Directives; Boeing Model 777-200 Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 777-200 series airplanes. This proposed AD would require replacing the pressure switches on the override/jettison fuel pumps with new pressure switches, and replacing the ship side electrical connectors for the pressure switches on override/jettison fuel pumps with new connectors. This proposed AD is prompted by reports that the ``FUEL LOW CENTER'' message does not activate when the fuel level in the center tank is low. We are proposing this AD to prevent the fuel pumps in the center fuel tank from running dry and becoming a potential ignition source, which could result in a fuel tank explosion.
Airworthiness Directives; Boeing Model 737-600, -700, -800, and -900 Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 737-600, -700, -800, and -900 series airplanes. This proposed AD would require installing and testing an updated version of the operational program software of the flight control computers. This proposed 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 proposing 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; 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 replacing eight brake fuses of the hydraulic quantity limiter with new or modified and reidentified fuses. This proposed AD is prompted by reports indicating that brake fuses of the hydraulic quantity limiter of the main landing gear have failed. We are proposing this AD to prevent loss of both hydraulic and brake systems if one fuse on each hydraulic system were to fail simultaneously, and consequent reduced controllability of the airplane.
Airworthiness Directives; Boeing Model 727-200 Series Airplanes Equipped With a No. 3 Cargo Door
The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 727-200 series airplanes equipped with a No. 3 cargo door. This proposed AD would require repetitive detailed and high frequency eddy current inspections for cracking of the forward, lower corner frame and forward end of the lower beam of the No. 3 cargo door, and corrective actions if necessary. The proposed AD provides an optional terminating action for the repetitive inspections. This proposed AD is prompted by reports of cracking at the forward, lower corner frame and lower beam of the No. 3 cargo door. We are proposing this AD to detect and correct cracking of the forward, lower corner frame and forward end of the lower beam of the No. 3 cargo door, which could result in failure of the affected door stops, loss of the cargo door, and consequent rapid decompression of the airplane.
Airworthiness Directives; Boeing Model 767-200, -300, and -300F Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 767-200, -300, and -300F series airplanes. This proposed AD would require installing a new, improved foam seal around certain ducts in the forward cargo compartment. This proposed AD is prompted by the detection of incorrectly installed smoke barrier seals around the electrical/electronic equipment air supply and exhaust ducts. We are proposing this AD to prevent fire extinguishing agent from leaking out of the seals around the ducts in the forward cargo compartment in the event of an in-flight fire, which could result in failure to extinguish the fire and consequent smoke or fire extinguishing agent entering a compartment occupied by passengers or crew.
Airworthiness Directives; Boeing Model 767-300 and -400ER Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 767-300 and -400ER series airplanes. This proposed AD would require 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 proposed 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 proposing 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; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-135 and EMB-145 Series Airplanes
The FAA is superseding an existing airworthiness directive (AD), which applies to certain EMBRAER Model EMB-135 and EMB-145 series airplanes. That AD currently requires replacing the nose landing gear wheel nuts and associated inner and outer seals, and reidentifying the landing gear strut. This new AD adds an airplane to the applicability and revises a part number for a replacement part. This AD is prompted by a report of an invalid part number for the new nose landing gear wheel nut. We are issuing this AD to prevent separation of the wheels from the nose landing gear due to the failure of the outer wheel bearings, and consequent loss of control of the airplane during takeoff and landing.
