Federal Aviation Administration May 2005 – Federal Register Recent Federal Regulation Documents

The Federal Aviation Administration (FAA) announces its determination that the noise exposure maps submitted by the County of San Diego for McClellan-Palomar Airport under the provisions of 49 U.S.C. 47501 et. seq. (Aviation Safety and Noise Abatement Act ) and 14 CFR part 150 are in compliance with applicable requirements.

The FAA is adopting a new airworthiness directive (AD) for CFM International CFM56-5, -5B, and -5C series turbofan engines. This AD requires removing certain part number (P/N) air turbine starters from service. This AD results from several reports of uncontained failures of air turbine starters where high-energy particles were not contained within the containment feature of the starter. We are issuing this AD to prevent uncontained failures of air turbine starters, which could result in damage to the airplane.

This document incorporates corrections to clarify the intent of Airworthiness Directive (AD) 2005-08-06, which was published in the Federal Register on April 19, 2005 (70 FR 20271). AD 2005-08-06 applies to all CENTRAIR 101 series gliders. This action clarifies the applicability to point out that the affected hinge pins were installed at manufacturer on serial numbers 101A600 through 101A637 and could be replaced on other serial number gliders with hinge pins that Centrair delivered between February 20, 1995, and February 28, 2001. We are re- issuing the AD in its entirety to help eliminate any confusion that this AD may have created.

The FAA proposes to adopt a new airworthiness directive (AD) for all transport category airplanes listed above. This proposed AD would require repetitive inspections for cracks of the main landing gear (MLG) shock strut cylinder, and related investigative and corrective actions if necessary. This proposed AD is prompted by two reports of a collapsed MLG and a report of cracks in two MLG cylinders. We are proposing this AD to detect and correct fatigue cracks in the shock strut cylinder of the MLG, which could result in a collapsed MLG during takeoff or landing, and possible reduced structural integrity of the airplane.

The FAA proposes to adopt a new airworthiness directive (AD) for certain Bombardier Model CL600-1A11 (CL-600), Model CL-600-2A12 (CL-601), and Model CL-600-2B16 (CL-601-3A, CL-601-3R, and CL-604) series airplanes. This proposed AD would require operators to assign serial numbers or part numbers to certain landing gear parts; and to establish the number of landings on the parts, if necessary. This proposed AD also would require operators to revise the Airworthiness Limitations section of the Instructions for Continued Airworthiness to reflect the new life limits of the landing gear parts. This proposed AD is prompted by reports that landing gear parts that have safe-life limits but do not have serial numbers or part numbers can be removed from one landing gear and re-installed on another, making tracking difficult. We are proposing this AD to prevent life-limited landing gear parts from being used beyond their safe-life limits, which could lead to collapse of the landing gear.

This amendment adopts a new airworthiness directive (AD) for Agusta S.p.A. (Agusta) Model A119 helicopters that requires visually inspecting each main transmission support fitting (fitting) attachment bolt (bolt) for a fracture, a crack, or looseness, and verifying the torque on each fitting bolt. This amendment is prompted by two incidents of fatigue failure of the bolts that secure the transmission rear support fittings to the helicopter. The actions specified by this AD are intended to detect a fracture, a crack, or looseness of a fitting bolt, and prevent fatigue failure of a fitting bolt and subsequent loss of control of the helicopter.

This amendment adopts a new airworthiness directive (AD) for Eurocopter France (Eurocopter) Model EC120 helicopters that requires inspecting the tail rotor drive shaft (drive shaft) damper half-clamps (half-clamps) to determine if they are centered on the friction ring, and if not correctly positioned, centering the half-clamps on the friction ring. This amendment is prompted by the discovery of half- clamps that were incorrectly positioned. The actions specified by this AD are intended to detect incorrect positioning of the drive shaft half-clamps, and to prevent interference of the half-clamps with the drive shaft, which could result in scoring on the drive shaft, failure of the drive shaft, and subsequent loss of control of the helicopter.

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 proposes to rule and invites public comment on the application to impose and use the revenue from a PFC at Cincinnati/ Northern Kentucky International Airport under the provisions of the 49 U.S.C. 40117 and Part 158 of the Federal Aviation Regulations (14 CFR part 158).

This action revokes Jet Route 711 (J-711), modifies Jet Routes 133 and 889R (J-133 and J-889R), and modifies two colored Federal airways (B-25 and A-1) in Alaska. The FAA is taking this action to remove all airways and routes off the Hinchinbrook, AK, Nondirectional Radio Beacon (NDB) in preparation for the NDB's eventual decommissioning from the National Airspace System (NAS).

The FAA is revising Airworthiness Directive (AD) 2004-25-16, which applies to aircraft equipped with a fuel regulator shutoff valve part number (P/N) 14D11, A14D11, B14D11, C14D11, 23D04, A23D04, B23D04, C23D04, or P23D04 used with B1500, B2030, B2500, B3040, B3500, B4050, or B4500 B-Series combustion heaters. AD 2004-25-16 currently requires you to repetitively inspect the fuel regulator shutoff valve (visually or by pressure test) for fuel leakage and replace the fuel regulator shutoff valve with an improved design replacement part with a manufacturer's date code of 02/02 or later if fuel leakage is found. AD 2004-25-16 also allows you to disable the heater as an alternative method of compliance. Since we issued AD 2004-25-16, we received several comments requesting a revision to paragraph (e)(2). Consequently, this AD retains the actions required in AD 2004-25-16 and revises the requirements in paragraph (e)(2) to remove a required action. We are issuing this AD to prevent failure of the fuel regulator shutoff valve, which could result in fuel leakage in aircraft with these combustion heaters. This failure could result in an aircraft fire.

In compliance with the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.), this notice announces that the Information Collection Requests (ICR) abstracted below have been forwarded to the Office of Management and Budget (OMB) for extension of the currently approved collections. The ICR describes the nature of the information collection and the expected burden. The Federal Register Notices with a 60-day comment period soliciting comments on the following collections of information were published on February 17, 2005, pages 8132-8133, with the exception of the notice for 2120-0574, which was published on August 25, 2004, page 52324.

This document confirms the effective date of the direct final rule which revises Class E airspace at Mountain Grove, MO.

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

This action establishes Class E airspace at Perryville, AK to provide adequate controlled airspace to contain aircraft executing a new Standard Instrument Approach Procedure (SIAP) and Departure Procedure. This rule results in new Class E airspace upward from 700 feet (ft.) and 1,200 ft. above the surface at Perryville, AK.

This action revises Class E airspace at St. Michael, AK to provide adequate controlled airspace to contain aircraft executing two new Standard Instrument Approach Procedures (SIAPs) and a new Textual Departure Procedure. This Rule results in new Class E airspace upward from 700 feet (ft.) above the surface at St. Michael, AK.

The FAA proposes to rule and invites public comment on the application to use the revenue from a PFC at Waterloo Municipal Airport under the provisions of the 49 U.S.C. 40117 and Part 158 of the Federal Aviation Regulations (14 CFR part 158).

This document makes a correction to Airworthiness Directive (AD) 2005-06-07. That AD applies to GE CF6-80A1/A3 and CF6-80C2A series turbofan engines. We published AD 2005-06-07 in the Federal Register on March 21, 2005, (70 FR 13365). A service bulletin number in the compliance section is incorrect. This document corrects that service bulletin number. In all other respects, the original document remains the same.

The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 747-400 and 747-400D series airplanes. This proposed AD would require an inspection for corrosion and cracks of the station 980 upper deck floor beam, and repair and related investigative actions if necessary. This proposed AD is prompted by reports of corrosion under the cart lift threshold at the station 980 upper deck floor beam. We are proposing this AD to detect and correct such corrosion, which could result in a cracked or broken floor beam, extensive damage to adjacent structure, and possible rapid decompression of the airplane.

This amendment establishes, amends, suspends, or revokes Standard Instrument Approach Procedures (SIAPs) for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, addition of new obstacles, or changes in air traffic requirements. These changes are designed to provide safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.

This action revises Class E airspace at Nome, AK to provide adequate controlled airspace to contain aircraft executing new Standard Instrument Approach Procedures (SIAP). This Rule results in additional Class E surface area and Class E airspace upward from 700 feet (ft.) and 1,200 ft. above the surface at Nome, AK.

The FAA proposes to supersede an existing airworthiness directive (AD) that applies to all BAE Systems (Operations) Limited (Jetstream) Model 4101 airplanes. The existing AD requires operators to determine the number of flight cycles accumulated on each component of the main landing gear (MLG) and the nose landing gear (NLG), and to replace each component that reaches its life limit with a serviceable component. The existing AD also requires operators to revise the Airworthiness Limitations section (ALS) of the Instructions for Continued Airworthiness in the aircraft maintenance manual to reflect the new life limits. This proposed AD would require revising the ALS to incorporate extended and more restrictive life limits for structurally significant items. This proposed AD is prompted by engineering analysis of fleet operations which resulted in more restrictive life limits. We are proposing this AD to prevent failure of certain structurally significant items, including the MLG and the NLG, which could result in reduced structural integrity of the airplane.

The FAA proposes to adopt a new airworthiness directive (AD) for all Boeing Model 737-600, -700, -700C, -800, and -900 series airplanes. This proposed AD would require repetitive inspections of the aft pressure bulkhead web for fatigue cracks, crack indications, discrepant holes, and corrosion, and repair if necessary. This proposed AD is prompted by reports of fatigue cracks in the aft pressure bulkhead web. We are proposing this AD to detect and correct such fatigue cracks, which could result in a rapid decompression of the airplane.
