Airworthiness Directives; BAE Systems (Operations) Limited Model BAe 146 and Avro 146-RJ Airplanes
The FAA proposes to supersede an existing airworthiness directive (AD) that applies to certain BAE Systems (Operations) Limited Model BAe 146 and Avro 146-RJ airplanes. The existing AD currently requires a one-time inspection to detect corrosion of the flap structure and machined ribs, corrective actions if necessary, and reprotection of the rib boss bores. This proposed AD would require a records review of the results of that inspection, and an additional inspection and related investigative/corrective action if necessary. This proposed AD results from the development of an improved inspection for corrosion in the subject area. We are proposing this AD to detect and correct corrosion in the flap structure and machined ribs, which could result in reduced structural integrity of the airplane.
Airworthiness Directives; Airbus Model A318, A319, A320, and A321 Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Model A318, A319, A320, and A321 airplanes. This proposed AD would require revising the Limitations section of the airplane flight manual (AFM); performing a one-time hardness test of certain ribs of the left- and right-hand engine pylons, as applicable, which would terminate the AFM limitations; and performing related corrective actions if necessary. This proposed AD results from a report that certain stainless steel ribs installed in the engine pylon may not have been heat-treated during manufacture, which could result in significantly reduced structural integrity of the pylon. We are proposing this AD to detect and correct reduced structural integrity of the engine pylon, which could lead to separation of the engine from the airplane.
Airworthiness Directives; Airbus Model A330-200, A330-300, A340-200, and A340-300 Series Airplanes, and Model A340-541 and A340-642 Airplanes
The FAA is revising an earlier NPRM for an airworthiness directive (AD) that would have applied to certain Airbus Model A330- 200, A330-300, A340-200, and A340-300 series airplanes, and A340-541 and A340-642 airplanes. The original NPRM would have required inspecting to determine if certain emergency escape slides/slide rafts (referred to as slide/rafts) are installed in certain crew/ passenger doors; and, if so, performing a one-time inspection to determine if the electrical harnesses of the slide/rafts are properly routed, and rerouting the harnesses if necessary. The original NPRM resulted from a report that a slide/raft failed to deploy properly during a deployment test. This action revises the original NPRM by expanding the applicability of the proposed AD. We are proposing this AD to detect and correct improper routing of the electrical harnesses of certain slide/rafts, which could prevent proper deployment of the slide/rafts and delay evacuation of passengers and flightcrew during an emergency.
Airworthiness Directives; Airbus Model A300 B4 Series Airplanes; Model A300 B4-600 Series Airplanes; Model A300 C4-605R Variant F Airplanes; Model A310-200 Series Airplanes; and Model A310-300 Series Airplanes
The FAA proposes to supersede an existing airworthiness directive (AD) that applies to certain Airbus Model A300 B4-600 and A300 C4-600 series airplanes. The existing AD currently requires a one- time inspection to detect damage of the pump diffuser guide slots (bayonet) of the center tank fuel pumps, the pump diffuser housings, and the pump canisters; repetitive inspections to detect damage of the fuel pumps and the fuel pump canisters; and corrective action, if necessary. This proposed AD would add, for new airplanes, repetitive inspections of the pump bodies for cracking, damage, and missing and broken fasteners; repetitive inspections of the fuel pump canisters for a cracked flange web; and corrective actions if necessary. For all airplanes, this proposed AD would also add replacement of the fuel pump canisters with new reinforced fuel pump canisters, which ends the repetitive inspections. This proposed AD results from fuel system reviews conducted by the manufacturer. We are proposing this AD to detect and correct damage of the center tank fuel pumps and fuel pump canisters, which could result in separation of a pump from its electrical motor housing, loss of flame trap capability, and a possible fuel ignition source in the center fuel tank.
Airworthiness Directives; Airbus Model A300 B2 and A300 B4 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 Series Airplanes)
The FAA is revising an earlier supplemental NPRM for an airworthiness directive (AD) that applies to certain Airbus airplanes as listed above. The first supplemental NPRM would have required repetitively inspecting for cracking in the web of nose rib 7 of the inner flap on the wings, and performing related investigative/ corrective actions if necessary. The original NPRM resulted from reports of cracking in the web of nose rib 7 of the inner flap. This action revises the first supplemental NPRM by requiring eventual replacement of nose rib 7 with a new, improved rib, which would terminate the proposed inspections. This action also removes from the applicability airplanes on which the improved nose rib 7 was installed during production. We are proposing this supplemental NPRM to prevent cracking in the web of nose rib 7, which could result in rupture of the attachment fitting between the inner flap and flap track 2, and consequent reduced structural integrity of the flap.
Airworthiness Directives; Airbus Model A300 B2 and A300 B4 Series Airplanes; A300 B4-600, B4-600R, and F4-600R Series Airplanes; and Model C4-605R Variant F Airplanes (Collectively Called A300-600 Series Airplanes)
The FAA is revising an earlier NPRM for an airworthiness directive (AD) that applies to certain Airbus Model A300 B2 and A300 B4 series airplanes, and A300-600 series airplanes. The original NPRM would have superseded an existing AD that currently requires repetitive inspections to detect cracks in Gear Rib 5 of the main landing gear (MLG) attachment fittings at the lower flange, and repair, if necessary. That AD also requires modification of Gear Rib 5 of the MLG attachment fittings, which constitutes terminating action for the repetitive inspections. The original NPRM proposed to reduce the compliance times for all inspections, and require doing the inspections in accordance with new revisions of the service bulletins. The original NPRM resulted from new service information that was issued by the manufacturer and mandated by the French airworthiness authority. This new action revises the original NPRM by proposing new repetitive inspections of certain areas of the attachment fittings that were repaired in accordance with the actions specified in both the existing AD and the original NPRM. We are proposing this supplemental NPRM to prevent fatigue cracking of the MLG attachment fittings, which could result in reduced structural integrity of the airplane.
Airworthiness Directives; Bombardier Model DHC-7 Airplanes
The FAA is revising an earlier NPRM for an airworthiness directive (AD) that applies to all Bombardier Model DHC-7 airplanes. The original NPRM would have required implementing a corrosion prevention and control program (CPCP) either by accomplishing specific tasks or by revising the maintenance inspection program to include a CPCP. The original NPRM resulted from a determination that, as airplanes age, they are more likely to exhibit indications of corrosion. This action revises the original NPRM by clarifying certain compliance aspects of the proposed AD that were not adequately defined in the original NPRM. We are proposing this supplemental NPRM to prevent structural failure of the airplane due to corrosion.
Airworthiness Directives; Pacific Aerospace Corporation Ltd. Model 750XL Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Pacific Aerospace Corporation Ltd. Model 750XL airplanes. This proposed AD would require you to inspect the condition of the insulation of the wiring adjacent to the electrical plugs mounted in the left-hand (LH) and right-hand (RH) sides of the forward end of the cockpit center console for signs of abrasion and arcing. If you find evidence of abrasion or arcing, this proposed AD would require you to replace the affected wire(s) and secure the wires away from the back shells of the electrical plugs. This proposed AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for New Zealand. We are proposing this AD to detect and correct damaged wires on the LH and RH sides of the forward end of the cockpit center console, which could result in short-circuiting of the related wiring. This could lead to electrical failure of affected systems and potential fire in the cockpit.

Programmatic Environmental Impact Statement: Launches and Reentries Under an Experimental Permit
The Commercial Space Launch Amendments Act of 2004 (CSLAA), enacted on December 23, 2004, directs the Secretary of Transportation and, through delegations, the Federal Aviation Administration (FAA) Office of Commercial Space Transportation, to establish an experimental permit regime for developmental reusable suborbital rockets. The intent of Congress for the experimental permit regime is to reduce the regulatory burden on developers of reusable suborbital rockets. Congress intended that, ``[a]t a minimum, permits should be granted more quickly and with fewer requirements than licenses.'' (H. Rep. 108.429 Sec. VII) To address the intent of Congress and meet a reduced timeline for issuing permits, a congressionally mandated 120 day timeline, the FAA is preparing a Programmatic Environmental Impact Statement (PEIS) to evaluate the impacts of launches and reentries conducted under an experimental permit. The intent of the PEIS is to facilitate the development of a permit application package and the subsequent environmental review by FAA, and to ensure that the issuance of an experimental permit is consistent with the FAA's mission of protecting public health and safety, safety of property, and the national security and foreign policy interests of the United States. The proposed action for this PEIS is to issue experimental permits for the launch and reentry of reusable suborbital rockets. Suborbital rocket means a vehicle, rocket-propelled in whole or in part, intended for flight on a suborbital trajectory, the thrust of which is greater than its lift for the majority of the rocket-powered portion of its ascent. Suborbital trajectory means the intentional flight path of a launch vehicle, reentry vehicle, or any portion thereof, whose vacuum instantaneous impact point does not leave the surface of the Earth. The FAA will prepare the PEIS in accordance with the National Environmental Policy Act (NEPA), the Council on Environmental Quality (CEQ) NEPA regulations (40 Code of Federal Regulations [CFR] Parts 1500-1508), and the FAA procedures for implementing NEPA in FAA Order 1050.1E.

Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-135 Airplanes and Model EMB-145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain EMBRAER Model EMB-135 airplanes and Model EMB-145, -145ER, - 145MR, -145LR, -145XR, -145MP, and -145EP airplanes. This AD requires replacing the horizontal stabilizer control unit (HSCU) with a modified and reidentified or new, improved HSCU. For certain airplanes, this AD also requires related concurrent actions as necessary. This AD is prompted by reports of loss of the pitch trim system due to a simultaneous failure of both channels of the HSCU. We are issuing this AD to prevent loss of pitch trim and reduced controllability of the airplane.
Airworthiness Directives; Airbus Model A318-100 Series Airplanes; Model A319-100 Series Airplanes; Model A320-111 Airplanes; Model A320-200 Series Airplanes; Model A321-100 Series Airplanes; and Model A321-200 Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A318-100 series airplanes; Model A319-100 series airplanes; Model A320-111 airplanes; Model A320-200 series airplanes; Model A321-100 series airplanes; and Model A321-200 series airplanes. This AD requires replacing the water drain valves in the forward and aft cargo doors with new valves. This AD results from a report indicating that, during a test of the fire extinguishing system, air leakage through the water drain valves in the forward and aft cargo doors reduced the concentration of fire extinguishing agent to below the level required to suppress a fire. We are issuing this AD to prevent air leakage through the water drain valves, which, in the event of a fire in the forward or aft cargo compartment, could result in an insufficient concentration of fire extinguishing agent and consequent inability of the fire extinguishing system to suppress the fire.
Airworthiness Directives; Airbus Model A330-200 and -300 Series Airplanes; and Model A340-200 and -300 Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A330-200 and A330-300 series airplanes; and Model A340-200 and -300 series airplanes. This AD requires repetitive detailed inspections for discrepancies of the inboard and outboard actuator fittings of the aileron servo controls, corrective actions if necessary, and eventual replacement of all the attachment bolts of the aileron servo controls. This AD results from several cases of bushing migration on the inboard and outboard actuator fittings of the aileron servo controls; in one case the bushing had migrated completely out of the actuator fitting and the fitting was cracked. We are issuing this AD to prevent rupture of the inboard and outboard actuator fittings of the aileron servo controls, which could result in airframe vibration and consequent reduced structural integrity of the airplane.
Airworthiness Directives; Airbus Model A318-100 and A319-100 Series Airplanes, A320-111 Airplanes, A320-200 Series Airplanes, and A321-100 and A321-200 Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A318-100 and A319-100 series airplanes, A320-111 airplanes, A320-200 series airplanes, and A321-100 and A321-200 series airplanes. This AD requires operators to review the airplane's maintenance records to determine the part numbers of the magnetic fuel level indicators (MFLI) of the wing fuel tanks, and related investigative and corrective actions if necessary. This AD results from several in-service incidents of wear and detachment of the top-stops from the MFLI. Such detachment allows the top-stop to move around the wing fuel tank, and the top-stop could come into contact or in close proximity with a gauging probe, resulting in compromise of the air gap between the probe and the structure and creating a potential ignition source. We are issuing this AD to prevent an ignition source in the wing fuel tank in the event of a lightning strike, which could result in a fire or explosion.
Airworthiness Directives; Aerospatiale Model ATR72 Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Aerospatiale Model ATR72 airplanes. This AD requires a one-time general visual inspection for contamination of the surface of the upper arms of the main landing gear (MLG) secondary side brace assemblies; and repetitive eddy current inspections for cracking of the upper arms, and related specified and corrective actions if necessary. This AD also mandates eventual replacement of aluminum upper arms with steel upper arms, which would end the repetitive inspections. This AD results from two reports of rupture of the upper arm of the MLG secondary side brace due to fatigue cracking. We are issuing this AD to prevent cracking of the upper arms of the secondary side brace assemblies of the MLG, which could result in collapse of the MLG during takeoff or landing, damage to the airplane, and possible injury to the flightcrew and passengers.
