Federal Aviation Administration 2005 – Federal Register Recent Federal Regulation Documents

The FAA proposes to adopt a new airworthiness directive (AD) for certain Learjet Model 23, 24, 24A, 24B, 24B-A, 24C, 24D, 24D-A, 24E, 24F, 24F-A, 25, 25A, 25B, 25C, 25D, and 25F airplanes. This proposed AD would require replacement of the spherical accumulator for the main hydraulic system with a new cylindrical accumulator. For certain airplanes, this proposed AD would also require modification of the accumulator pressure gauge. This proposed AD is prompted by reports of the failure of two thrust reverser accumulators (which are similar to the main hydraulic system's spherical accumulator) and fatigue cracks found on four thrust reverser accumulators. We are proposing this AD to prevent failure of the spherical accumulator for the main hydraulic system, due to fatigue cracking on the threads, which could result in the loss of hydraulic power, damage to the surrounding airplane structure, and loss of airplane control. The failure of the accumulator could also result in injury to any persons in the surrounding area. The loss of hydraulic fluid could also leak onto a potential source of ignition and result in a consequent fire.

This action proposes to extend Federal Airway V-343 from the Bozeman, MT Very High Frequency Omni-directional Range/Tactical Air Navigation (VORTAC) to the initial approach fix for the Area Navigation (RNAV) runway 15 approach to the Bert Mooney Airport (BTM), MT. Specifically, the FAA is proposing this action to enhance the management of air traffic arrivals at BTM.

This action establishes Class E airspace at Marion, KY. Area Navigation (RNAV) Global Positioning System (GPS) Standard Instrument Approach Procedures (SIAP) Runway (RWY) 7 and RWY 25 have been developed for Marion-Crittenden County Airport. As a result, controlled airspace extending upward from 700 feet Above Ground Level (AGL) is needed to contain the SIAPs and for Instrument Flight Rules (IFR) operations at Marion-Crittenden County Airport. The operating status of the airport will change from Visual Flight Rules (VFR) to include IFR operations concurrent with the publication of the SIAP.

The FAA proposes to rule and invite public comment on the release of land at the Pueblo Memorial Airport under the provisions of Section 125 of the Wendell H. Ford Aviation Investment Reform Act for the 21st Century (AIR 21).

The FAA proposes to rule and invite public comment on the release of land at the Pueblo Memorial Airport under the provisions of Section 125 of the Wendell H. Ford Aviation Investment Reform Act for the 21st Century (AIR 21).

This amendment realigns the boundary of the Class D airspace area at Worcester Regional Airport, MA. This action will incorporate a shelf and cutout of the Worcester Class D airspace area to accommodate the airport traffic pattern for Spencer Airport (60M).

The FAA proposes to rule and invite public comment on the release of land at the Pueblo Memorial Airport under the provisions of Section 125 of the Wendell H. Ford Aviation Investment Reform Act for the 21st Century (AIR 21).

The FAA proposes to rule and invite public comment on the release of land at the Centennial Airport under the provisions of Section 125 of the Wendell H. Ford Aviation Investment Reform Act for the 21st Century (AIR 21).

The FAA proposes to rule and invite public comment on the release of land at the Salt Lake City International Airport under the provisions of Section 125 of the Wendell H. Ford Aviation Investment Reform Act for the 21st Century (AIR 21).

The FAA proposes to supersede an existing airworthiness directive (AD) for General Electric Company (GE) CF34-1A, -3A, -3A1, - 3A2, -3B, and -3B1 turbofan engines. That AD currently requires a onetime inspection, and if necessary replacing certain fan disks for electrical arc-out indications. That AD also reduces the life limit of certain fan disks. This proposed AD would require the same actions and adds one disk part number (P/N) and serial number (SN) to the affected fan disks. This proposed AD results from an error in the first part number and serial number listed in Table 1 of the original AD. We are proposing this AD to prevent rupture of the fan disk due to cracks that initiate at an electrical arc-out, which could result in an uncontained failure of the engine.

The FAA is adopting a new airworthiness directive (AD) for certain Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. This AD requires inspecting to identify the wing anti-ice ducts (piccolo tubes) in the wing leading edge. For airplanes with affected piccolo tubes, this AD requires revising the airplane flight manual (AFM) to introduce new procedures for operation in icing conditions. The optional implementation of repetitive inspections for cracks of affected piccolo tubes, and corrective actions if necessary, terminates the operational limitations. The optional installation of certain new piccolo tubes terminates both the AFM revision and the inspections. This AD was prompted by reports of failed piccolo tubes. We are issuing this AD to prevent cracked piccolo tubes, which could result in air leakage, a possible adverse effect on the anti-ice air distribution pattern and anti-ice capability without annunciation to the flight crew, and consequent reduced controllability of the airplane.

The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A321 series airplanes. This AD requires repetitive measurements for correct control rod gap of the hold-open mechanism of all emergency doors, and corrective actions if necessary. This AD also requires replacing the control rods with new, improved control rods, which would terminate the repetitive measurements. This AD results from a report that an operator found it impossible to lock emergency doors 2 and 3 in the open position. We are issuing this AD to prevent failure of the emergency doors to lock in the open position, which could interfere with passenger evacuation during an emergency.

The FAA is adopting a new airworthiness directive (AD) for certain Saab Model SAAB 2000 airplanes. This AD requires an inspection for cracking of the fastener holes in the front and rear spars, a modification of the fastener holes of the front and rear spars and the rear spar web, and related investigative/corrective actions if necessary. This AD is prompted by a report of cracking of certain fastener holes in the lower spar cap of the rear spar and in the lower skin at the front spar. We are issuing this AD to prevent cracking of the front and rear spars, which could result in fuel leakage and consequent reduced structural integrity of the wing structure.

The FAA is adopting a new airworthiness directive (AD) for certain GE CF6-80C2 and CF6-80E1 turbofan engines. This AD requires you to inspect the high pressure compressor rotor (HPCR) stage 11-14 spool shaft for circumferential repair cuts, and to repair or replace the spool shaft if you find certain circumferential cuts. This AD results from an updated stress analysis. We are issuing this AD to prevent failure of the HPCR stage 11-14 spool shaft due to low-cycle fatigue that could result in an uncontained engine failure.

This document incorporates corrections to add service information to Airworthiness Directive (AD) 2005-13-09, which was published in the Federal Register on June 22, 2005 (70 FR 35993). AD 2005-13-09 applies to certain GROB-WERKE Model G120A airplanes. This action adds GROB-WERKE Service Bulletin No. MSB1121-052/2, dated February 14, 2005, to paragraphs (e)(1), (e)(2), and (h) of AD 2005-13- 09. This service information was included in the notice of proposed rulemaking (NPRM) for this AD, but we inadvertently omitted it in the final rule request for comments. We are re-issuing the AD in its entirety to help eliminate any confusion that this AD may have created.

This document revises an earlier proposed airworthiness directive (AD), applicable to certain Boeing Model 727-100 and -100C series airplanes, that would have required repetitive inspections of the frame inner chord, outer chord, and web of the forward and aft edge frames of the lower lobe forward cargo door (FCD) cutout, and corrective action if necessary. This new action revises the proposed rule by adding high frequency eddy current inspections and a detailed inspection for cracks of certain areas described above. This new action also removes one airplane from the applicability. The actions specified by this new proposed AD are intended to detect and correct fatigue cracking of the forward and aft edge frames of the lower lobe FCD cutout, which could result in the loss of the FCD and rapid decompression of the airplane. This action is intended to address the identified unsafe condition.

The FAA proposes to adopt a new airworthiness directive (AD) for all Bombardier Model DHC-7 series airplanes. This proposed AD would require implementing a corrosion prevention and control program (CPCP) either by accomplishing specific tasks or by revising the maintenance inspection program to include a CPCP. This proposed AD is prompted by the determination that, as airplanes age, they are more likely to exhibit indications of corrosion. We are proposing this AD to prevent structural failure of the airplane due to corrosion.

The FAA proposes to adopt a new airworthiness directive (AD) for all CENTRAIR 101 Series gliders. This proposed AD would require you to make pen and ink changes to the Limitations Section of the glider maintenance manual to eliminate contradictory information concerning the structural life limit. This proposed AD results from a review by FAA of the Limitations Section of the CENTRAIR Model 101AP glider maintenance manual that revealed conflicting information concerning the structural life limit. We are issuing this proposed AD to assure that the published life limit is adhered to and to prevent structural failure of the glider once this life limit is reached.

Pursuant to FAA's rulemaking provisions governing the application, processing, and disposition of petitions for exemption, part 11 of title 14, Code of Federal Regulations (14 CFR), this notice contains the disposition of certain petitions previously received. The purpose of this notice is to improve the public's awareness of, and participation in, this aspect of FAA's regulatory activities. Neither publication of this notice nor the inclusion or omission of information in the summary is intended to affect the legal status of any petition or its final disposition.

The FAA is issuing this notice to advise the public of a meeting of RTCA Special Committee 204: 406 MHz Emergency Locator Transmitters.

This document confirms the effective date of the direct final rule which revises Class E airspace at McCook, NE.

These special conditions are issued for Gulfstream Model G150 airplanes. These airplanes will have a novel or unusual design feature(s) associated with side-facing single-occupant seats. 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.

The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 777-200 and -300 series airplanes. This AD requires inspecting the valve control and indication wire bundles of the fuel system of the wing rear spar for discrepancies, and corrective action if necessary. This AD is prompted by reports of six incidents of the wire bundles chafing against the rear spar stiffeners outside the fuel tank. We are issuing this AD to prevent this chafing, which could result in wire damage leading to a short circuit, subsequent ignition of flammable vapors, and possible uncontrollable fire during fueling or flight.

The FAA is revising Airworthiness Directive (AD) 95-19-15 for all Tiger Aircraft LLC (Type Certificate A16EA 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. That AD was written to apply to all serial numbers of all models. A design change was made in this area beginning with serial number 10175 of the Model AG-5B airplanes. Therefore, the action should not apply to Model AG-5B airplanes with a serial number of 10175 or higher. This AD retains all the actions of AD 95-19-15 for all airplanes originally affected, but cuts off the applicability for the Model AG-5B airplanes at serial number 10174. We are issuing this AD to continue 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.

The FAA proposes to adopt a new airworthiness directive (AD) for General Electric Company (GE) CF6-45A, CF6-50A, CF6-50C, and CF6- 50E series turbofan engines. This proposed AD would require removing from service pre-GE Service Bulletin (SB) No. CF6-50 S/B 72-1268 configuration low pressure turbine (LPT) stage 2 interstage seal assemblies and stage 3 interstage seal assemblies. The proposed AD would also require installing new or reworked configuration stage 2 interstage seal assemblies and stage 3 interstage seal assemblies. This proposed AD results from reports of fan mid shaft separation, leading to separation of the LPT stage 1 disk, disk overspeed, and uncontained engine failure. We are proposing this AD to prevent uncontained engine failure and damage to the airplane.
