Airworthiness Directives; EMBRAER Model EMB-135BJ Airplanes
Document Number: E8-470
Type: Rule
Date: 2008-01-16
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model ERJ 170 and ERJ 190 Airplanes

Airworthiness Directives; Airbus Model A310 Series Airplanes
Document Number: E8-370
Type: Rule
Date: 2008-01-16
Agency: Federal Aviation Administration, Department of Transportation
The FAA is superseding an existing airworthiness directive (AD), that applies to certain Airbus Model A310 series airplanes. That AD currently requires modification of certain wires in the right-hand (RH) wing. This new AD requires further modification by installing an additional protection sleeve and segregating route 2S in the RH pylon area. This AD results from analysis of wire routing that revealed that route 2S of the fuel electrical circuit, located in the RH wing, does not provide adequate separation of fuel quantity indication wires from wires carrying 115-volt alternating current (AC). We are issuing this AD to ensure that fuel quantity indication wires are properly separated from wires carrying 115-volt AC. Improper separation of such wires, in the event of wire damage, could lead to a short circuit and a possible ignition source, which could result in a fire in the airplane.
Airworthiness Directives; EMBRAER Model EMB-120, -120ER, -120FC, -120QC, and -120RT Airplanes
Document Number: E8-170
Type: Rule
Date: 2008-01-16
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product.

Airworthiness Directives; Airbus Model A300 Airplanes; and Model A300 B4-600, B4-600R, and F4-600R Series Airplanes, and Model C4-605R Variant F Airplanes (Collectively Called A300-600 Series Airplanes)
Document Number: E7-25503
Type: Rule
Date: 2008-01-16
Agency: Federal Aviation Administration, Department of Transportation
The FAA is superseding an existing airworthiness directive (AD), which applies to all Airbus Model A300 B2 and B4 series airplanes; and all Model A300 B4-600, B4-600R, and F4-600R (collectively called A300-600) series airplanes. That AD currently requires repetitive inspections to detect cracking of the upper radius of the forward fitting of frame 47, and repair if necessary. This new AD retains those requirements, but reduces inspection thresholds and repetitive intervals, and adds related investigative and corrective actions. This AD also provides an optional terminating action for the repetitive inspections only for airplanes with cracking that is within certain limits, and a post-repair inspection program following the optional terminating action. This AD results from reports of additional cracking in airplanes that were inspected in accordance with the existing AD. We are issuing this AD to detect and correct fatigue cracking of the left and right upper radius at frame 47, which could propagate and result in reduced structural integrity of the airplane.
Airworthiness Directives; McDonnell Douglas Model DC-10-10, DC-10-10F, DC-10-15, and MD-10-10F Airplanes
Document Number: E8-385
Type: Proposed Rule
Date: 2008-01-14
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for certain McDonnell Douglas Model DC-10-10, DC-10-10F, DC-10-15, and MD- 10-10F airplanes. This proposed AD would require repetitive inspections for the presence of stray nickel or chrome plating deposits on the air filler valve bore of certain main landing gear (MLG) shock strut cylinders, and if necessary, related investigative and corrective actions. Doing the corrective action would terminate the repetitive inspections. This proposed AD results from a report of a left MLG collapse during landing rollout. We are proposing this AD to detect and correct stray nickel and chrome plating deposits, corrosion, and cracking of the air filler valve bore on the MLG cylinder, which could result in landing gear failure, significant damage to the airplane, and injury to personnel.
Airworthiness Directives; Boeing Model 727-200 Series Airplanes Equipped With an Auxiliary Fuel Tank System Installed in Accordance With Supplemental Type Certificate SA1350NM
Document Number: E8-384
Type: Proposed Rule
Date: 2008-01-14
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 727-200 series airplanes. This proposed AD would require deactivation of auxiliary fuel tank systems installed in accordance with Supplemental Type Certificate (STC) SA1350NM. This proposed AD results from fuel tank system reviews conducted by the manufacturer that identified potential unsafe conditions for which the manufacturer has not provided corrective actions. We are proposing this AD to prevent the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.
Airworthiness Directives; Airbus Model A318, A319, A320, and A321 Airplanes
Document Number: E8-383
Type: Proposed Rule
Date: 2008-01-14
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to supersede an existing airworthiness directive (AD) that applies to certain Airbus Model A318, A319, A320, and A321 airplanes. The existing AD currently requires repetitive inspections for cracking in the forward lug of the support rib 5 fitting of both main landing gear (MLG), and repair if necessary. The existing AD also provides optional terminating actions for certain airplanes, as well as other optional methods for complying with the inspection requirements of the existing AD. This proposed AD would continue to require repetitive inspections for cracking in the forward lug of the support rib 5 fitting of the left and right MLG at new repetitive intervals in accordance with new service information, and repair or replacement of any cracked MLG fitting if necessary. This proposed AD would also require modification of the rib bushings of the left and right MLG, which would end the repetitive inspections. This proposed AD results from cracks found in the forward lug of the MLG support rib 5 fitting. We are proposing this AD to prevent cracking in the forward lug of the MLG, which could result in failure of the lug and consequent collapse of the MLG during takeoff or landing.
Airworthiness Directives; Airbus Model A310 Series Airplanes and A300-600 Series Airplanes
Document Number: E8-380
Type: Proposed Rule
Date: 2008-01-14
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to supersede two existing airworthiness directives (ADs). One existing AD applies to certain Airbus Model A310 series airplanes and requires repetitive inspections for cracking of the flap transmission shafts, and replacing the transmission shafts if necessary. That existing AD also provides an optional terminating action for the repetitive inspections. The other existing AD applies to all Airbus Model A310 and A300-600 series airplanes and requires a one- time inspection of the trimmable horizontal stabilizer actuator (THSA), corrective actions if necessary, and follow-on repetitive tasks. This proposed AD would require revising the Airworthiness Limitations Section of the Instructions for Continued Airworthiness to incorporate new limitations and maintenance tasks for aging systems maintenance. This proposed AD results from the manufacturer's determination that life limitations and maintenance tasks are necessary in order to ensure continued operational safety of the affected airplanes. We are proposing this AD to prevent reduced structural integrity of these airplanes due to the failure of system components.
Airworthiness Directives; Boeing Model 767-200, -300, and -400ER Series Airplanes
Document Number: E8-378
Type: Proposed Rule
Date: 2008-01-14
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 767-200, -300, and -400ER series airplanes. This proposed AD would require an inspection to determine the manufacturer and manufacture date of the oxygen masks in the passenger service units and the flight attendant and lavatory oxygen boxes, as applicable. This proposed AD would also require related investigative/ corrective actions if necessary. This proposed AD results from a report that several passenger masks with broken in-line flow indicators were found following a mask deployment. We are proposing this AD to prevent the in-line flow indicators of the passenger oxygen masks from fracturing and separating, which could inhibit oxygen flow to the masks and consequently result in exposure of the passengers and cabin attendants to hypoxia following a depressurization event.

Type: Rule
Date: 2008-01-07
Agency: Federal Aviation Administration, Department of Transportation
The FAA is revising an existing airworthiness directive (AD) that applies to all Boeing Model 747 series airplanes. That AD currently requires that the FAA-approved maintenance inspection program be revised to include inspections that will give no less than the required damage tolerance rating for each structural significant item, and repair of cracked structure. We issued that AD to ensure the continued structural integrity of the entire fleet of Model 747 series airplanes. This new AD clarifies the applicability of the existing AD by specifying which Boeing Model 747 airplanes are affected by this AD because we have determined that certain new variants that have not yet been certified will not be subject to the requirements of this AD. This AD results from a report of incidents involving fatigue cracking in transport category airplanes that are approaching or have exceeded their design service objective. We are issuing this AD to ensure the continued structural integrity of all Boeing Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-200C, 747-200F, 747-300, 747-400, 747-400D, 747-400F, 747SR, and 747SP series airplanes.

The FAA is adopting a new airworthiness directive (AD) for PW PW4164, PW4168, and PW4168A turbofan engines with certain low pressure turbine (LPT) stage 4 disks, part number (P/N) 51N404, installed. This AD requires removing certain LPT stage 4 disks, listed by serial number at the next piece-part exposure or within 7,500 cycles-since-new (CSN). This AD results from a report of improperly manufactured LPT stage 4 disks. We are issuing this AD to prevent an uncontained engine failure due to low-cycle fatigue (LCF), which could result in damage to the airplane.
Special Conditions; Adam Aircraft Industries Model A700; External Fuel Tank Protection During Gear-Up or Emergency Landing
Document Number: E7-25466
Type: Rule
Date: 2008-01-03
Agency: Federal Aviation Administration, Department of Transportation
These special conditions are issued for the Adam Aircraft Industries Model A700 airplane. This airplane will have a novel or unusual design feature(s) associated with an External Centerline Fuel Tank (ECFT) that increases the total capacity of fuel by 184 gallons. The tank is located below the fuselage pressure shell immediately below the wing. The Adam A700 ECFT is a novel, unusual and a potentially unsafe design feature that may pose a hazard to the occupants during a gear-up or emergency landing due to fuel leakage and subsequent fire. Traditional aircraft construction places the fuel tanks in a protected area within the wings and/or fuselage. Fuel tanks located in these areas are well above the fuselage skin and are inherently protected by the wing and fuselage structure. 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.
Airworthiness Directives; Robinson Helicopter Company Models R22, R22 Alpha, R22 Beta, R22 Mariner, R44 and R44 II Helicopters
Document Number: E7-25395
Type: Rule
Date: 2008-01-03
Agency: Federal Aviation Administration, Department of Transportation
This amendment adopts a new airworthiness directive (AD) for the specified Robinson Helicopter Company (Robinson) helicopters. This action requires a one-time visual inspection for skin separation along the leading edge of blade skin aft of the skin-to-spar bond line on the lower surface of each blade and in the tip cap area. This action also requires a ``tap test'' for detecting a separation or void in both bonded areas. This action also requires repainting any exposed area of the blades. If any separation or void is detected, replacing the blade before further flight is required. Thereafter, before each flight, this AD also requires checking for any exposed (bare metal) along the skin-to-spar bond line on the lower surface of each blade near the tip. If any bare metal is found, a mechanic must inspect the area. This amendment is prompted by 11 reports of blade debond, some occurring in flight causing the pilot to feel excessive vibrations and land, and some found during routine maintenance. The actions specified in this AD are intended to detect blade skin debond and to prevent blade failure and subsequent loss of control of the helicopter.

Airworthiness Directives; Cessna Model 680 Airplanes
Document Number: 07-6265
Type: Rule
Date: 2008-01-03
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for certain Cessna Model 680 airplanes. This AD requires inspecting the routing of the aft fairing wire bundle assembly for adequate separation between the wiring and the hydraulic line; inspecting for chafing or damage of the wire bundle assembly and for damage to the hydraulic line, and doing corrective actions if necessary. This AD results from an incident report which indicated that a hydraulic leak and wire chafing, including signs of heat damage, were found within the lower tail cone fairing area. Similar wire chafing has also been found on other airplanes. We are issuing this AD to detect and correct wire chafing, and inadequate separation of the wiring and hydraulic line, which could lead to electrical arcing and a hydraulic leak and could result in a potential source of ignition and consequent fire.
Airworthiness Directives; Various Transport Category Airplanes Equipped With Auxiliary Fuel Tanks Installed in Accordance With Certain Supplemental Type Certificates
Document Number: E7-25482
Type: Proposed Rule
Date: 2008-01-02
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for various transport category airplanes. This proposed AD would require deactivation of Southeast Aero-Tek, Inc., auxiliary fuel tanks. This proposed AD results from fuel system reviews conducted by the manufacturer, which identified potential unsafe conditions for which the manufacturer has not provided corrective actions. We are proposing this AD to prevent the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.
Airworthiness Directives; Construcciones Aeronauticas, S.A., (CASA) Model C-212 Airplanes
Document Number: E7-25481
Type: Proposed Rule
Date: 2008-01-02
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for the products listed above that would supersede an existing AD. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
Airworthiness Directives; Boeing Model 737-600, -700, -700C, -800 and -900 Series Airplanes
Document Number: E7-25477
Type: Proposed Rule
Date: 2008-01-02
Agency: Federal Aviation Administration, Department of Transportation
The FAA is revising an earlier proposed airworthiness directive (AD) for certain Boeing Model 737-600, -700, -700C, -800 and -900 series airplanes. The original NPRM would have required sealing the fasteners on the front and rear spars inside the main fuel tank and on the lower panel of the center fuel tank, inspecting the wire bundle support installation in the equipment cooling system bays to identify the type of clamp installed and determine whether the Teflon sleeve is installed, and doing related corrective actions if necessary. The original NPRM resulted from a design review of the fuel tank systems. This action revises the compliance time for the corrective actions specified in the original NPRM. We are proposing this supplemental NPRM to prevent arcing at certain fuel tank fasteners in the event of a lightning strike or fault current event, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.
Special Conditions: Boeing Model 787-8 Airplane; Systems and Data Networks Security-Isolation or Protection From Unauthorized Passenger Domain Systems Access
Document Number: E7-25467
Type: Rule
Date: 2008-01-02
Agency: Federal Aviation Administration, Department of Transportation
These special conditions are issued for the Boeing Model 787-8 airplane. This airplane will have novel or unusual design features when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. These novel or unusual design features are associated with connectivity of the passenger domain computer systems to the airplane critical systems and data networks. For these design features, the applicable airworthiness regulations do not contain adequate or appropriate safety standards for protection and security of airplane systems and data networks against unauthorized access. 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 standards. Additional special conditions will be issued for other novel or unusual design features of the Boeing Model 787-8 airplanes.

These airplanes, as modified by AmSafe Aviation, will have novel and unusual design features associated with the lap belt or shoulder harness portion of the safety belt, which contains an integrated airbag device. The applicable airworthiness regulations do not contain adequate and 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 airworthiness standards.
Airworthiness Directives; General Electric Company CF6-45 and CF6-50 Series Turbofan Engines
Document Number: E7-25458
Type: Proposed Rule
Date: 2008-01-02
Agency: Federal Aviation Administration, Department of Transportation
This supplemental NPRM revises an earlier proposed airworthiness directive (AD), applicable to certain General Electric Company (GE) CF6-45 and CF6-50 series turbofan engines. That proposed AD would have required inspecting and reworking certain forward and aft centerbodies of the long fixed core exhaust nozzle (LFCEN) assembly. That proposed AD resulted from reports of separation of the forward and aft centerbodies of the LFCEN assembly due to high-imbalance engine conditions. This supplemental NPRM revises the proposed AD to add one engine model, and by replacing the LFCEN instead of repairing the centerbodies. This proposed AD results from the engine manufacturer issuing new service information. We are proposing this AD to prevent the forward and aft centerbody of the LFCEN assembly from separating, leading to additional damage to the airplane.
