Airworthiness Directives; Airbus Model A300 Airplanes; Model A310 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 NPRM for an airworthiness directive (AD) that applies to all Airbus Model A300 airplanes and Model A310 airplanes, and certain Airbus Model A300-600 series airplanes. The original NPRM would have superseded an existing AD that currently requires an inspection of the wing and center fuel tanks to determine if certain P-clips are installed and corrective action if necessary; an inspection of electrical bonding points of certain equipment in the center fuel tank for the presence of a blue coat and related investigative and corrective actions if necessary; and installation of new bonding leads and electrical bonding points on certain equipment in the wing, center, and trim fuel tanks, as necessary. The original NPRM proposed to require, for certain airplanes, installation of bonding on an additional bracket. The original NPRM resulted from fuel system reviews conducted by the manufacturer. This new action revises the original NPRM by adding a requirement, for certain airplanes, to modify the fuel/defuel valves on the left-hand wing. We are proposing this supplemental NPRM to ensure continuous electrical bonding protection of equipment in the wing, center, and trim fuel tanks and to prevent damage to wiring in the wing and center fuel tanks, due to failed P-clips used for retaining the wiring and pipes, which could result in a possible fuel ignition source in the fuel tanks.
Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-135 and EMB-145 Series Airplanes
This action withdraws a notice of proposed rulemaking (NPRM) that proposed a new airworthiness directive (AD), applicable to certain EMBRAER Model EMB-135 and EMB-145 series airplanes. That action would have required an inspection of the base and support surfaces of the glide slope antenna and of certain electrical connectors of the navigation system, and applicable corrective actions if necessary. Since the issuance of the NPRM, we have received new data showing that the proposed inspection and corrective actions will not eliminate the display of erroneous or misleading information to the flightcrew in the cockpit. However, we have been informed that the navigation system manufacturer has developed effective corrective actions to address the unsafe condition identified in the NPRM. Since we issued the NPRM, we have issued other rulemaking, which provides corrective actions for the identified unsafe condition. Accordingly, the proposed rule is withdrawn.
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 a one-time inspection of each fuel quantity indication system (FQIS) wire harness connector for corrosion of the shield-to-backshell connection, corrosion on the ground jumper, and damage to the ground jumper; a loop resistance test of each FQIS wire harness; and related investigative and corrective actions if necessary. This proposed AD results from reports of corrosion of the out-tank wire harness of the spar connector backshell for the FQIS. We are proposing this AD to detect and correct corrosion of the out-tank wire harness, which could prevent correct grounding of the lightning shield and result in total loss of the electrical grounding between the lightning shield and the airplane structure. This condition, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.
Improving Public Safety Communications in the 800 MHz Band
The Commission clarifies the standard for determining the acceptability of costs that Sprint Nextel Corporation (Sprint) is required to pay in connection with the 800 MHz rebanding process. Specifically, the Commission clarified the provision in the 800 MHz Report and Order that such costs must be the ``minimum necessary'' to accomplish rebanding of 800 MHz licensees in a reasonable, prudent and timely manner
Airworthiness Directives; Airbus Model A318, A319, A320, and A321 Airplanes
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by an airworthiness authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as a fire in the auxiliary power unit air intake. We are issuing this AD to require actions to correct the unsafe condition on these products.
Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-145XR Airplanes
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; Boeing Model 747-400, 747-400D, and 747-400F Series Airplanes
The FAA is superseding an existing airworthiness directive (AD), which applies to all Boeing Model 747-400, -400D, and -400F series airplanes. That AD currently requires revising the airplane flight manual (AFM) to require the flightcrew to maintain certain minimum fuel levels in the center fuel tanks, and to prohibit the use of the horizontal stabilizer fuel tank. This new AD requires installing new integrated display system (IDS) software; and also requires revising the AFM to include procedures to prevent dry operation of the center wing and horizontal stabilizer fuel tanks, for maintaining minimum fuel levels, and for de-fueling fuel tanks. For certain airplanes, this new AD also requires removing certain program pin ground wires of the IDS. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to reduce the potential for 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; Boeing Model 777 Airplanes
The FAA is adopting a new airworthiness directive (AD) for all Boeing Model 777 airplanes. This AD requires repetitive measurements of the freeplay of the right and left elevators, rudder, and rudder tab, and related investigative and corrective actions if necessary. This AD also requires repetitive lubrication of the elevator, rudder, and rudder tab components. This AD results from reports of freeplay-induced vibration of unbalanced control surfaces. Excessive freeplay of control surfaces can cause unacceptable airframe vibration during flight. The potential for vibration of the control surface should be avoided because the point of transition from vibration to divergent flutter is unknown. We are issuing this AD to prevent flutter, which can cause damage to the control surface structure and consequent loss of control of the airplane.
Airworthiness Directives; BAE Systems (Operations) Limited Model BAe 146 and Avro 146-RJ Airplanes
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; McDonnell Douglas Model 717-200 Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain McDonnell Douglas Model 717-200 airplanes. This AD requires installing a certain junction(s) and changing the wiring of the first officer's pitot static heater system. This AD results from a report of temporary loss of the auto-flight function with displays of suspect or erratic airspeed indications. We are issuing this AD to prevent display of suspect or erratic airspeed indications during heavy rain conditions, which could reduce the ability of the flightcrew to maintain the safe flight and landing of the airplane.
Airworthiness Directives; Airbus Model A330 and A340 Airplanes
The FAA is superseding an existing airworthiness directive (AD), which applies to certain Airbus Model A330-200, A330-300, A340- 200, and A340-300 series airplanes; and Model A340-541 and -642 airplanes. That AD currently requires repetitively resetting the display units (DUs) for the electronic instrument system (EIS), either by switching them off and back on again or by performing a complete electrical shutdown of the airplane. This new AD requires installing new software, which would end the actions required by the existing AD. This new AD also adds additional airplanes that may be placed on the U.S. Register in the future. This AD results from an incident in which all of the DUs for the EIS went blank simultaneously during flight. We are issuing this AD to prevent automatic reset of the DUs for the EIS during flight and consequent loss of data from the DUs, which could reduce the ability of the flightcrew to control the airplane during adverse flight conditions.
Airworthiness Directives; McDonnell Douglas Model DC-8-62, DC-8-62F, DC-8-63, DC-8-63F, DC-8-72, DC-8-72F, and DC-8-73F Airplanes
The FAA is adopting a new airworthiness directive (AD) for all McDonnell Douglas Model DC-8-62, DC-8-62F, DC-8-63, DC-8-63F, DC-8-72, DC-8-72F, and DC-8-73F airplanes. This AD requires deactivating certain components (the sump heater, scavenge valve, and scavenge pump) of the center wing fuel tank. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent certain conditions related to these components, which could lead to a possible ignition source in the fuel tank and a potential fire or explosion.
Airworthiness Directives; Gulfstream Model GIV-X, GV, and GV-SP Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Gulfstream Model GIV-X, GV, and GV-SP series airplanes. This AD requires revising the airplane flight manuals (AFMs) of those airplanes, and doing repetitive functional checks of the forward water drain/supply valves and applicable corrective actions. This AD also provides for optional terminating action for the repetitive functional checks. This AD results from reports of failed forward water drain/ supply valves on numerous airplanes, and reports of ice striking the wing-to-body fairings and engine nose cowls of several airplanes. We are issuing this AD to prevent leakage from failed water drain/supply valves allowing the build-up of ice on the airplane, which could separate and strike the airplane structure aft of the failed valves; become ingested by a propulsion engine; or become a hazard to persons or property on the ground.
Airworthiness Standards; Propellers; Reopening of Comment Period
On April 11, 2007, the FAA published a Notice of Proposed Rulemaking (NPRM) regarding the revision of airworthiness standards for the issuance of original and amended type certificates for airplane propellers. The comment period closed on June 11, 2007. However, the FAA is reopening the comment period for an additional 45 days in response to requests from McCauley Propeller Systems, Hartzell Propeller, Inc., and the General Aviation Manufacturers Association. The reopening of the comment period is needed to permit these companies, and other affected parties, additional time to develop comments responsive to the NPRM.
