Airworthiness Directives; Pratt & Whitney PW4164, PW4168, and PW4168A Series Turbofan Engines
The FAA proposes to supersede an existing airworthiness directive (AD) for Pratt & Whitney (PW) PW4164, PW4168, and PW4168A series turbofan engines. That AD currently requires initial and repetitive torque checks for loose or broken front pylon mount bolts made from INCO 718 material and MP159 material, and initial and repetitive visual inspections of the primary mount thrust load path. This proposed AD would require the same actions, but at reduced intervals for front pylon mount bolts made from MP159 material. This proposed AD results from analysis by the manufacturer that the MP159 material pylon bolts do not meet the full life cycle torque check interval requirement, in a bolt-out condition. We are proposing this AD to prevent front pylon mount bolt and primary mount thrust load path failure, which could result in an engine separating from the airplane.
Airworthiness Directives; Honeywell International Inc., (Formerly AlliedSignal, Inc., Formerly Textron Lycoming, Formerly Avco Lycoming) T5311A, T5311B, T5313B, T5317A, T5317A-1, T5317B Series Turboshaft Engines and Lycoming Former Military T53-L-11B, T53-L-11D, T53-L-13B, T53-L-13B/D, and T53-L-703 Series Turboshaft Engines
The FAA proposes to supersede an existing airworthiness directive (AD), AD 98-22-11, for AlliedSignal, Inc. T5317A-1 turboshaft engines. That AD currently requires repetitive engine fuel pump pressure tests of certain fuel control regulator assemblies to determine if both fuel pumps in the fuel control regulator assemblies are producing fuel pressure. That AD also requires replacing the fuel control regulator assembly, if necessary. This proposed AD would require initial and repetitive visual and dimensional inspections of fuel control regulator assembly main and secondary drive shaft and pump gear splines, installed in certain fuel control regulator assemblies. This proposed AD would also expand the engine applicability, and include certain engines installed on helicopters certified under Sec. 21.25 or 21.27 of the Code of Federal Regulations (14 CFR 21.25 or 14 CFR 21.27). This proposed AD results from several reports of loss of fuel flow from the engine fuel control regulator assembly due to failure of both main and secondary drive shaft and pump gear splines. We are proposing this AD to prevent in-flight engine failure and forced autorotation landing.
Human Space Flight Requirements for Crew and Space Flight Participants
The FAA proposes requirements for human space flight of crew and space flight participants as required by the Commercial Space Launch Amendments Act of 2004. If adopted, this rulemaking would establish requirements for crew qualifications, training, and notification. It would also establish training and informed consent requirements for space flight participants. The rulemaking would also modify existing financial responsibility requirements to account for the FAA's new authority for space flight participants and crew, and to issue experimental permits. The experimental permit is the subject of a separate rulemaking. The FAA is conducting this rulemaking in order to fulfill its responsibilities under the new act. The requirements are designed to provide an acceptable level of safety to the general public, and to notify individuals on board of the risks associated with a launch or reentry.
Service Difficulty Reports
The Federal Aviation Administration (FAA) is withdrawing a delayed final rule published on September 15, 2000. That final rule would have amended the reporting requirements for certificate holders concerning failures, malfunctions, and defects of aircraft, aircraft engines, systems, and components. We are withdrawing this rule to allow the FAA time to re-examine the service difficulty report (SDR) program and consider the comments received since the delayed final rule was published. In this action we are also adopting several amendments that improve the functioning of the SDR program.
Airworthiness Directives; Airbus Model A320-111 Airplanes, and Model A320-200 Series Airplanes
This document corrects information in an existing airworthiness directive (AD) that applies to certain Airbus Model A320- 111 airplanes, and Model A320-200 series airplanes. That AD currently requires a detailed inspection of the tail cone triangle to determine its position, and corrective actions if necessary. This document corrects the applicability by specifying that the AD affects only airplanes identified in Airbus Service Bulletin A320-27-1132, Revision 01, dated June 19, 2002. This correction is necessary to ensure that only affected airplanes are subject to the requirements of the AD.
