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:

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.

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.

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.

We propose to adopt a new airworthiness directive (AD) for the products listed above. 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.

We are adopting a new airworthiness directive (AD) for certain oxygen reserve cylinders. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country with which we have a bilateral agreement to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:

The MCAI describes the unsafe condition as:

The FAA is correcting an error in an existing airworthiness directive (AD) that was published in the Federal Register on November 13, 2007 (72 FR 63800). The error resulted in the wrong appendix information. This AD applies to all Boeing Model 707 airplanes and Model 720 and 720B series airplanes. This AD requires accomplishing an airplane survey to define the configuration of certain system installations, and repair of any discrepancy found. This AD also requires modifying the fuel system by installing lightning protection for the fuel quantity indication system (FQIS), ground fault relays for the fuel boost pumps, and additional power relays for the center tank fuel pumps and uncommanded on-indication lights at the flight engineer's panel.

The FAA proposes to supersede an existing airworthiness directive (AD) that applies to 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. The existing AD currently requires a one-time inspection of the horizontal hinge pin of the 103VU electrical panel in the avionics compartment to determine if the hinge pin can move out of the hinge, and related investigative and corrective actions if necessary. This proposed AD would require installing a hinge pin stopper on the internal door of the 103VU electrical panel. This proposed AD results from a report indicating that electrical wire damage was found in the 103VU electrical panel due to contact between the hinge pin and the adjacent electrical wire harness. We are proposing this AD to prevent contact between the horizontal hinge pin and the adjacent electrical wire harness, which could result in damage to electrical wires, and consequent arcing and/or failure of associated systems.

This action will establish Class E airspace at Wheatland, WY. Additional Class E airspace is necessary to accommodate aircraft using a new Area Navigation (RNAV) Global Positioning System (GPS) Standard Instrument Approach Procedure (SIAP) at Phifer Airfield. This will improve the safety of Instrument Flight Rules (IFR) aircraft executing the new RNAV GPS SIAP at Phifer Airfield, Wheatland, WY.

The FAA is revising an existing airworthiness directive (AD) that applies to all Boeing Model 747 series airplanes. That AD currently requires the implementation of a corrosion prevention and control program. We issued that AD to prevent degradation of the structural capabilities of the affected 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 reports of incidents involving corrosion and cracking in transport category airplanes, which have jeopardized the airworthiness of the affected airplanes. We are issuing this AD to prevent degradation of the structural capabilities 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 superseding an existing airworthiness directive (AD), which applies to certain Boeing Model 747-200B, 747-200C, 747- 200F, 747-300, 747-400, and 747SP series airplanes. That AD currently requires doing a detailed inspection of the left and right longeron extension fittings, and corrective action if necessary. This new AD adds airplanes to the applicability of the existing AD. This AD results from reports that accidental drilling damage to the longeron extension fittings was found on airplanes not subject to the existing AD. We are issuing this AD to detect and correct accidental drilling damage of the longeron extension fittings, which could lead to cracking of the longeron extension fittings and result in rapid decompression of the airplane.

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: ``An accumulator cylinder had material defects and suffered an in-flight burst failure causing damage to the aircraft structure.'' We are issuing this AD to require actions to correct the unsafe condition on these products.

The Federal Aviation Administration (FAA) announces its determination that the Noise Exposure Maps submitted by the Greater Orlando Airport Authority for Orlando Executive Airport under the provisions of 49 U.S.C. 47501 et seq. (Aviation Safety and Noise Abatement Act) and 14 CFR Part 150 are in compliance with the applicable requirements. The FAA also announces that it is reviewing a proposed Noise Compatibility Program that was submitted for Orlando Executive under Part 150 in conjunction with the Noise Exposure Map, and that this program will be approved or disapproved on or before June 28, 2008.

We propose to adopt a new airworthiness directive (AD) for the products listed above.

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.

This AD results from mandatory continuing airworthiness information (MCAI) issued 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:

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.

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.

These special conditions are issued for AmSafe Aviation for a list of approved models. 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.

We propose to adopt a new airworthiness directive (AD) for the products listed above.
