Airworthiness Directives; Turbomeca Arriel 1B, 1D and 1D1 Turboshaft Engines
Document Number: 05-22007
Type: Proposed Rule
Date: 2005-11-04
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for Turbomeca Arriel 1B, 1D and 1D1 turboshaft engines. This proposed AD would require inspecting the 2nd stage nozzle guide vanes (NGV2) for wall thickness. This proposed AD results from one instance of a fractured 2nd stage turbine blade followed by an uncommanded engine shutdown. We are proposing this AD to detect and prevent perforation of the NGV2 that could cause fracture of a turbine blade that could result in an uncommanded engine in-flight shutdown.

Airworthiness Directives; General Electric Company CF6-80E1 Series Turbofan Engines
Document Number: 05-21805
Type: Rule
Date: 2005-11-02
Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for General Electric Company (GE) CF6-80E1 series turbofan engines installed on Airbus Industrie A330 series airplanes. This AD requires a check of the holding torque of the thrust reverser actuation system (TRAS) locks, and if necessary a visual inspection of the TRAS lock flexible drive shafts, within 10 flight cycles after all aborted takeoffs in which the thrust reverser was deployed. This AD results from reports of operators finding several damaged TRAS lock flexible drive shafts during inspections and checks of the drive shafts. We are issuing this AD to prevent inadvertent in-flight deployment of the thrust reverser, which can result in loss of control of the airplane.
Airworthiness Directives; Pratt & Whitney JT9D Series Turbofan Engines
Document Number: 05-21804
Type: Proposed Rule
Date: 2005-11-02
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to supersede an existing airworthiness directive (AD) for Pratt & Whitney (PW) JT9D series turbofan engines. That AD currently requires revisions to the Airworthiness Limitations Section (ALS) of the manufacturer's Instructions for Continued Airworthiness (ICA) to include required enhanced inspection of selected critical life-limited parts at each piece-part opportunity. This proposed AD would modify the JT9D series engines ALS sections of the manufacturer's manuals and an air carrier's approved continuous airworthiness maintenance program to incorporate additional inspection requirements. The mandatory inspections are needed to identify those critical rotating parts with conditions, which if allowed to continue in service, could result in uncontained failures. We are proposing this AD to prevent critical life-limited rotating engine part failure, which could result in an uncontained engine failure and damage to the airplane.
Airworthiness Directives; Honeywell International Inc., (Formerly AlliedSignal, Inc. and Textron Lycoming) ALF502L Series and ALF502R Series Turbofan Engines
Document Number: 05-21802
Type: Proposed Rule
Date: 2005-11-02
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to supersede an existing airworthiness directive (AD), AD 95-04-11, for Honeywell International Inc., (formerly AlliedSignal, Inc. and Textron Lycoming) ALF502L series and ALF502R series turbofan engines. That AD currently establishes stress rupture retirement life limits for certain third stage turbine discs used in conjunction with certain third stage turbine nozzles. This proposed AD would bring requirements forward and unchanged, from the previous AD for ALF502R series turbofan engines. Also, this proposed AD would establish new reduced stress rupture retirement life limits for certain part numbers (P/Ns) of third stage turbine disc and shaft assemblies installed in ALF502L series turbofan engines. This proposed AD would also require removing those same parts from service using a drawdown schedule. This proposed AD results from a report of failure of a third stage turbine disc and shaft assembly, leading to turbine blade release and separation of the exhaust nozzle. We are proposing this AD to prevent total loss of engine power, in-flight engine shutdown, release of turbine blades, separation of the exhaust nozzle, and possible damage to the airplane.

Finding of No Significant Impact
Document Number: 05-21746
Type: Notice
Date: 2005-11-01
Agency: Federal Aviation Administration, Department of Transportation
On May 23, 2005, the FAA Office of Commercial Space Transportation (AST) received an application for a launch license from Space Exploration Technologies, Inc. (SpaceX) to conduct launches of its Falcon 1 launch vehicle from Omelek Island, U.S. Army Kwajalein Atoll/Ronald Reagan Ballistic Missile Test Site (USAKA/RTS). The FAA participated as a cooperating agency with the U.S. Army Space and Missile Defense Command (USASMDC) in preparation of the Environmental Assessment (EA) for the Proof-of-Principle Space Launches from Omelek Island (February 2005). The EA analyzed the environmental consequences of conducting two proof-of-principle launches of the Falcon 1 Launch Vehicle from Omelek Island, USAKA/RTS. From its independent review and consideration, the FAA has determined that the FAA's proposed action is substantially the same as the actions already analyzed in the USASMDC EA and that FAA's comments and suggestions have been satisfied (see 1506.3(c) and FAA Order 1050.1E, 518h). The FAA formally adopts the EA and hereby incorporates the analysis to support its decision on this license application. After reviewing and analyzing currently available data and information on existing conditions, project impacts, and measures to mitigate those impacts, the FAA has determined that licensing the proposed launch activities is not a Federal action that would significantly affect the quality of the human environment within the meaning of the National Environmental Policy Act (NEPA). Therefore, the preparation of an Environmental Impact Statement (EIS) is not required and the FAA is issuing a Finding of No Significant Impact (FONSI). The FAA made this determination in accordance with all applicable environmental laws.

Airworthiness Directives; AvCraft Dornier Model 328-100 Airplanes
Document Number: 05-21697
Type: Proposed Rule
Date: 2005-11-01
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to revise an existing airworthiness directive (AD) that applies to all AvCraft Dornier Model 328-100 airplanes. The existing AD currently requires revising the Airplane Flight Manual (AFM) to provide the flightcrew with additional information regarding procedures to ensure complete pressurization of the hydraulic lines for the flaps. The existing AD also requires, for certain airplanes, modification of the flap actuators of the flight controls. This proposed AD would allow the removal of the AFM revisions after modifying the flap actuators of the flight controls. This proposed AD results from the determination that the AFM revisions are not necessary after modifying the flap actuators of the flight controls. We are proposing this AD to prevent an uncommanded retraction of the flaps during takeoff, which could result in an aborted takeoff and consequent potential for runway overrun.
