Airworthiness Directives; The Cessna Aircraft Company Models 525, 525A, and 525B Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain The Cessna Aircraft Company (Cessna) Models 525, 525A, and 525B airplanes. This proposed AD would require you to install identification sleeves on the wiring for both engine fire extinguisher bottles. This proposed AD results from reports of incorrectly connecting the wires to the engine fire extinguisher bottles. We are issuing this proposed AD to prevent incorrect installation of the wires to the engine fire extinguisher bottles, which could result in failure of the engine fire extinguisher bottles to discharge when activated. This failure could lead to the inability to control an engine fire.
Airworthiness Directives; Turbomeca Arrius 2F Turboshaft Engines
This document publishes in the Federal Register an amendment adopting emergency airworthiness directive (AD) 2005-09-51 that we sent previously to all known U.S. owners and operators of certain Turbomeca Arrius 2F turboshaft engines. This AD requires before further flight, replacing the Module 2 on certain engines listed by serial number (SN) in this AD. This AD results from a report of the failure of a high pressure turbine (HPT) blade and damage to two other HPT blades in a Turbomeca Arrius 2F turboshaft engine. We are issuing this AD to prevent failure of the engine and subsequent loss of power.
Airworthiness Directives; Tiger Aircraft LLC Models AA-5, AA-5A, AA-5B, and AG-5B Airplanes
The FAA proposes to revise Airworthiness Directive (AD) 95-19- 15, which applies to all Tiger Aircraft LLC (Type Certificate A16EH formerly held by American General Aircraft Corporation and Grumman American Aviation Corporation) Models AA-5, AA-5A, AA-5B, and AG-5B airplanes. AD 95-19-15 currently requires you to inspect the wing attach shoulder bolts for fretting, scoring, wear, or enlarged or elongated mounting holes (known as damage from hereon); replace any damaged parts; repair any damaged areas; inspect the wing spar at the center spar clearance gap for excessive clearance; and shim the spar if excessive clearance is found. Since we issued AD 95-19-15, FAA has received and evaluated new service information that limits the serial numbers for the Model AG-5B airplanes of AD 95-19-15. Consequently, this proposed AD retains all the actions of AD 95-19-15 and includes the serial numbers for the Model AG-5B airplanes in the applicability section. We are issuing this proposed AD to prevent wing attach shoulder bolt failure, which, if not detected and corrected, could lead to structural damage of the wing/fuselage to the point of failure.
Airworthiness Directives; General Electric (GE) CF6-80E1 Series Turbofan Engines
The FAA is adopting a new airworthiness directive (AD) for General Electric (GE) CF6-80E1 series turbofan engines that have an electronic control unit (ECU) with software version E.1.M. or earlier installed. This AD requires installing improved software for the ECU. This AD results from an uncommanded engine acceleration event caused by a failure of the ECU digital interface unit (DIU). We are issuing this AD to prevent an undetected failure of the ECU DIU, which could result in uncommanded acceleration to the overspeed limit without response to throttle commands. The airplane could then experience asymmetric thrust.
Airworthiness Directives; Boeing Model 747 Airplanes
The FAA is superseding an existing airworthiness directive (AD), which applies to certain Boeing Model 747 airplanes. That AD currently requires inspections to detect cracks in the front spar pressure bulkhead chord, and repair if necessary. This new AD requires repetitive high frequency eddy current (HFEC) inspections of the body station (BS) 1000 bulkhead chord for cracks, repetitive detailed inspections of the bathtub fittings, if installed, for cracks, and corrective action if necessary. Initiation of the new inspections ends the inspections of the existing AD. This AD also revises the applicability of the existing AD to include additional airplanes. This AD is prompted by reports of cracks in the BS 1000 bulkhead chord. We are issuing this AD to detect and correct fatigue cracks in the BS 1000 bulkhead chord, which, if not repaired before they reach critical length, could result in the failure of the adjacent structure and skin and lead to in-flight depressurization of the airplane.
Airworthiness Directives; Boeing Model 747-100, -100B, -100B SUD, -200B, -200C, -300, -400, and -400D Series Airplanes; and Model 747SR Series Airplanes
The FAA is superseding an existing airworthiness directive (AD), which applies to certain Boeing Model 747 series airplanes. That AD currently requires a one-time inspection to determine the material type of the stop support fittings of the main entry doors (MEDs). That AD also currently requires repetitive detailed inspections to detect cracks of certain stop support fittings of the MEDs, and replacement of any cracked stop support fitting with a certain new stop support fitting. This new AD adds new inspections, and replacement if necessary, of the stop support fittings of MED 3, and adds airplanes to the applicability. This AD is prompted by reports of MED 3 having certain stop support fittings that are susceptible to stress corrosion cracking. We are issuing this AD to detect and correct stress corrosion cracking of the stop support fittings of the MEDs, which could result in damage to the adjacent forward edge frame of the door and consequent loss of a MED and rapid decompression of the airplane.
Airworthiness Directives; Boeing Model 777-200 and -300 Series Airplanes
This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 777-200 and -300 series airplanes, that requires modification of the bolt holes of the lower side of the body splice t-chord common to the paddle fittings of the lower wing panel. The modification includes performing a high frequency eddy current inspection of the fastener holes for cracks, repairing the hole if necessary, and replacing the fasteners with new inconel bolts. This action is necessary to prevent fatigue cracks in the lower t-chord at the bolt holes common to the paddle fittings that could result in fractures of one or more of the t-chord segments, which could lead to detachment of the lower wing panel and consequent loss of the wing. This action is intended to address the identified unsafe condition.
Airworthiness Directives; Boeing Model 747-100, 747-100B, 747-200B, 747-300, 747-400, 747-400D, 747SR, and 747SP Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 747-100, 747-100B, 747-200B, 747-300, 747-400, 747-400D, 747SR, and 747SP series airplanes. This AD requires replacing or modifying the control panels for the galley cart lift and modifying related electrical cable assemblies, as applicable. This AD is prompted by reports of injuries to catering personnel and flight attendants who were loading or unloading galley carts on one deck when, due to a disabled or malfunctioning safety interlock door switch, the galley cart lift unexpectedly moved when it was activated from the control panel on the other deck. We are issuing this AD to ensure that the galley cart lift can be sent only from the deck on which it is in use, which will prevent unexpected movement of the cart lift that could result in possible injury to catering personnel or flight attendants.
Airworthiness Directives; Boeing Model 777-200 Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 777-200 series airplanes. This AD requires replacing the pressure switches on the override/jettison fuel pumps with new pressure switches, and replacing the ship side electrical connectors for the pressure switches on override/jettison fuel pumps with new connectors. This AD is prompted by reports that the ``FUEL LOW CENTER'' message does not activate when the fuel level in the center tank is low. We are issuing this AD to prevent the fuel pumps in the center fuel tank from running dry and becoming a potential ignition source, which could result in a fuel tank explosion.
Definition of Commuter Aircraft at Ronald Reagan Washington National Airport
The Federal Aviation Administration (FAA) is amending the regulations for aircraft permitted to operate in commuter slots at Ronald Reagan Washington National Airport (DCA). This change is necessary to conform the regulations to amendments set forth in the Vision 100Century of Aviation Reauthorization Act of 2003 (Vision 100) Section 426, which increases the maximum seating capacity for aircraft used in commuter slots at DCA.
Airport Noise Compatibility Planning
On September 24, 2004, the Federal Aviation Administration (FAA) published a final rule, with request for comments, to amend the regulations implementing airport noise compatibility planning. The amendment included revisions stemming from changes to the authorizing legislation that had not been incorporated into the implementing regulations. In addition, the final rule contained several minor, technical changes. This action is a summary and disposition of the comments received in response to that final rule.
Miscellaneous Changes to Commercial Space Transportation Regulations
This proposal would prohibit obtrusive space advertising and make other minor changes to the regulations governing commercial space transportation. The proposed changes are necessary to reflect a statutory change, capture current practice, and to correct errors in a table. The purpose of the changes is to give the public and the regulated industry accurate and current information.
